Air purification in the classroom. Is it effective?

For a sustainable resumption of activity in schools, it is essential that classrooms are free of all kinds of contaminants. Of course, this can be achieved by using proven hygiene systems, such as a classroom air purifier, to keep the air free from viruses. The coronavirus is a major challenge for teachers, cleaning staff and school directors. Even regular disinfection by spraying and wiping does not protect against this virus, which hardly spreads by contact and droplets, but mainly through the ambient air. Therefore, in order to protect pupils and teachers, proven measures must be taken to reliably reduce the risk of airborne contamination. Can a classroom air purifier effectively reduce the risk of covid-19 infection? In this article, we tell you everything you need to know about air purification in the classroom. As well as the studies that support it and what to look out for when choosing an air purifier for the classroom.


Air purification against viruses for safer school activities

Face-to-face classes involve proximity between people, spontaneous reactions through gestures, behaviour, questions and answers. So teachers cannot do without direct contact if they want to do their pedagogical work.

However, such direct contact always entails the risk of contracting an airborne infectious disease. In the most innocent case: influenza, in times of coronavirus: Covid-19. Therefore, in addition to the usual hygiene measures, it is advisable to keep the ambient air and the breathing zone as clean and free from bacteria and viruses as possible. To protect the teachers, but also the pupils. This will prevent absenteeism and the spread of contagious diseases. The question is whether an air cleaner in the classroom is the best option for keeping the air in the classroom free from viruses.


Clean air in classrooms protects teachers and pupils

Viruses and bacteria are an invisible danger in every classroom. Pathogens can survive in the ambient air for several hours, during which time they pose a potential health risk each time they are inhaled. For example, current studies show that the coronavirus survives in the air for several hours and during that time it also retains its infectious capacity.

It is important to note that the virus enters the room air through aerosols emitted during breathing and talking. The viruses attach themselves to these small particles and form virulent aerosols that, due to their light weight, float in the air and are inadvertently inhaled by other people in the classroom, such as other students and teachers. Opening windows is not an effective measure for eliminating these aerosols. Therefore, many experts wonder whether air cleaning in the classroom can be an effective measure.

Strategies to prevent infection in the classroom

Reducing class size has been a basic part of the hygiene strategy in many countries. But no matter how small the groups are, the virus continues to spread. And the use of face masks only provides limited protection against the direct “viral rain” of saliva emitted when talking. Unfortunately, these measures have not proved effective against the aerosols containing germs that are released into the ambient air through breathing and talking and that remain floating freely as an aerosol cloud for several hours.

Just by talking loudly, every person emits thousands of aerosols into the air every minute. Singing in a group releases even more. Masks are an important first step in reducing the risk of direct drop transmission of the coronavirus. However, this measure alone does not protect against a much greater risk of transmission: free-floating aerosol clouds in the ambient air.


Aerosols and coronavirus

Such aerosol clouds overcome even the physical barriers formed by a saliva screen or partitions, so that aerosol particles always find their way to the respiratory tract and the eyes. The long floatation period of aerosols also reveals another problem. Since aerosols spread through the air current, the air mixes in a room every time the door opens and closes.

Only a comprehensive solution, synchronised with other hygiene measures and additional air purification, can reliably and sustainably reduce the risk of infection. Especially since, according to TU/E, cleaning the air in classrooms can reduce the risk of infection with the coronavirus by up to 12 times. Therefore, do not rely solely on spatial separation, masks or more frequent hand washing than usual to prevent infection in classrooms. Airborne aerosols are a health risk that can only be avoided by cleaning the air in the classroom.

The proven effectiveness of air purification in the classroom

Keeping the air in the room free from germs and viruses minimises the risk of airborne infection. Studies have shown that air purifiers for classrooms effectively and quickly reduce the residence time and intensity of aerosol clouds and airborne particles in closed rooms. This creates schools with a very low risk of infection for pupils and teaching staff.

But not every air purifier is equally effective. Essential are:

  • Powerful air purifiers. Their power ensures that they can consistently and effectively clean all the air in the classroom.
  • Air purifiers with HEPA filter and UVC system. This enables the air purifier to remove not only air pollutants such as fine dust, but also viruses and bacteria.
  • Quiet air purifiers. Since it is a classroom, you also need to consider the noise they generate so that it does not disturb.
  • No ozone emissions. Ozone is very harmful to health, especially for children.


The best air cleaner against bacteria and viruses in the classroom

The UV-C air purifier EDC650 is the solution against virus particles and bacteria in the classroom. Thanks to the UV-C lamps and HEPA filters, you can effectively repel micro-organisms (such as viruses) with this professional air cleaner. Moreover, the EDC650 UV-C uses unique and patented circulation and filtration techniques: reverse air circulation combined with air displacement. According to TNO, this method of air purification removes airborne contaminants up to 30% more effectively than ordinary air purifiers. Not only is it a model approved by the FPS, but it is also on the list of air purification products in Belgium that have been checked and approved against the coronavirus.

Moreover, the EDC650 UV-C is quiet in operation. Depending on the air speed, the decibel level ranges from a pleasant 27 to 49 dB. This is comparable to a quiet classroom or living room. Thanks to its high capacity and quiet operation, the EDC650 UV-C is ideal for the classroom, both in schools and in higher education.

Ambient scenting in healthcare | handling bad smells

Scent marketing in the healthcare sector seems contradictory. After all, scent marketing is not one of the main tasks in a hospital. Yet it is very useful because of the bad smells that often hang around in nursing homes or hospitals. Thanks to the deep link between what we smell and how we feel, olfactory perception in healthcare has many applications. Hospital scenting makes the care facility a nicer place for patients and staff, . Keep reading to find out how to best use scenting in your care facility and for what purposes.


Why is scenting useful in healthcare?

There are always a lot of scents in healthcare. No matter how much you keep cleaning you can’t escape sweat, industrial cleaning products or incontinence odours. This, of course, is not pleasant for anyone. Especially if you have to work in it every day, it’s unpleasant. For patients, it can make the experience in your institution unnecessarily unpleasant or stressful. A better experience of smells in healthcare is therefore desirable. Ideally, you would like to get rid of these bad odours and replace them with ambient scents that people like. With an efficient odour control in healthcare this is possible. The reason why odours affect us so much is deeply connected to our brain.


How does smell work in our brain?

Our sense of smell is actually different from all our other senses. During the day we are much more aware of what we see and hear. Yet smells have a much greater impact on our emotions and our peace of mind. This is because of where our brains process smells. Because smell is the first sense to have evolved, it lies deep within our brains, near the place where emotions are regulated. Therefore, the connections between smell and emotions are very strong. Research has shown that what we smell determines 75% of our emotions. If something smells bad, we immediately feel uncomfortable. If we hear bad music, we don’t! In this way, the scent experience in health care can have a great influence.


Ambient scenting in healthcare


What does scenting do in healthcare?

Scent marketing often emphasises the commercial benefits. It is said to increase the turnover and the number of impulse purchases. You might think that it makes little sense for a hospital. After all, there are few people who buy a heart transplant on impulse! However, scenting has considerable advantages in the care sector. You get rid of bad smells and you spread nice fragrances through the rooms. So you have a double advantage! That is why healthcare scenting offers concrete advantages for the staff and the patients.


What do patients gain from healthcare scenting?

The biggest benefit of hospital scenting for patients is the influence of scent on emotions. When there are bad smells in for instance a nursing home, it is very uncomfortable for patients. Even neutral smells such as cleaning products sometimes evoke bad emotions. This is because people associate these smells with negative memories, such as an operation in a hospital. In contrast, it has been shown that positive smells make a stay in a hospital a lot more pleasant.

Patients feel less anxious about an operation if there is a pleasant smell. For example, the scents of jasmine and citrus make us feel more relaxed and happy. Fragrances also influence how patients experience pain. With a pleasant smell, people experience pain as less bad and less intense, with a bad smell this is the other way around. With scenting in healthcare you get rid of bad smells and you can spread fine smells throughout the room.


And how does ambient scenting affect healthcare staff?

For the staff it is of course also much nicer to work in an environment that smells good. This is not the case in every nursing home. Because of the strong link with emotions, an environment with nice fragrances leads to more job satisfaction and a lower outflow. In a sector where the workload is high, every little bit of extra relaxation and job satisfaction is of course very welcome. Ambient scenting in the healthcare sector also has the effect of making people more effective in their work. Certain smells reduce stress, increase concentration or cognitive function. Ambient scenting in health care has many advantages.


Advantages of scenting in healthcare

  • Removes bad odours. In hospitals and nursing homes there are often bad smells.
  • Patients are more at ease. Scent diffusion makes patients less anxious and more relaxed. This makes their stay more pleasant.
  • Greater job satisfaction. Staff who do not have to work in bad odours enjoy more their work.
  • Improve the focus of your staff. Certain odours can improve the concentration and activity of your staff.
  • Reduces stress. Patients and staff are less stressed in an environment with good fragrance.


Odour neutralization or scent diffusion?

Scenting in healthcare comes in roughly two variations. Odour neutralization and scent diffusion. With odour neutralization we mean the devices that make bad odours like sweat and incontinence disappear. This happens by breaking down the odour molecules on a molecular level. The result is a neutral odour. Scent diffusers go one step further. These devices add an odour to a room. With a professional scent diffuser you set exactly when you want which smell. It also ensures that the scent lingers in the room and does not disappear. This is done with ethereal scent oils.


Ambient scenting in healthcare


Which scent device do I need?

If you want to get rid of bad smells, the Superscent is the best choice. This powerful device is suitable for rooms up to 210 square metres. By using the Superscent to actually break down bad smells, you are not masking the bad odour, but actually getting rid of it. Odour control at its best! This keeps the environment comfortable for patients and staff. If you want to experience smells, the Scent Experience is a very suitable choice. With this, you spread the scent you want, when you want it. This powerhouse among the scent machines has several variants with which it is suitable for up to 800m2. With our Scent Experience you create a nicer environment for the patients and your staff.

Enhance your shop with scent marketing

Enhance your shop with scent marketing

As a retailer you are busy making the customer experience as pleasant as possible. Yet scent marketing in retail is often ignored. You design the shop perfectly and choose the right music. But what we smell has the biggest impact on how we feel and behave. So to make your shop stand out from the competition, good scent marketing is essential. How to use scent marketing in your shop and for what purposes you can use it read here.


Scent in the brain

Our environment largely determines how we feel and behave. When we hear a nice song or see a beautiful painting we feel more cheerful. Although we are often less aware of what we smell, it has a much greater effect. This has to do with where our brain processes odours. This happens right next to our so-called “emotion centre“. Therefore the connections between emotions and smells are strong. When we smell something, our brain immediately sends signals to our emotion centre. Scents therefore have a strong influence on how we feel. Think about how you feel when you smell the fragrance of a fresh forest in a garden centre. Scent marketing in a shop should not be underestimated!


What effects does scent marketing have in my shop?

Scenting has all kinds of concrete effects. Customers find shops more pleasant when there is a pleasant fragrance. They also judge the products offered as better with a nice fragrance. Another important effect has to do with memory. People remember things better when an emotion is linked to them. Because odours have such a strong influence on emotions, memories are also strengthened. A pleasant smell creates a positive association with your shop or showroom and people remember your brand better. With scent marketing in retail, people come back to your shop more often. This increases customer loyalty.


scentmarketing shop


Does scent marketing increase the turnover of my shop?

Besides the fact that people experience the environment as a lot nicer, scent marketing in a shop also has commercial applications. Several studies have investigated the effects of olfactory marketing in retail. It appeared that the number of impulse purchases increases with almost a third. People also stay longer in shops with a strong pleasant fragrance. At the same time this time feels shorter: people underestimate how long they have been in a shop with scent marketing! This actually results in a higher turnover, estimated on average 14% more.


Does shop scent marketing also have an impact on my staff?

Customers are not the only ones who benefit from a nice fragrance, your employees do too. After all they work all day in for example your clothing shop. Different smells can also be used to make your staff more productive. When there is an uplifting smell such as coffee in the room the cognitive skills of people improve. Some fragrances also help to reduce stress and increase concentration. When people work in an environment that smells good, they are also more ambitious and work more efficiently. In addition, all the previously mentioned benefits about emotions also apply of course. A pleasant smell makes your employees happier and they work with more pleasure. So scent marketing does a lot for your shop.


The five advantages of retail scent marketing at a glance:

  • Create a nicer environment for your customers and staff
  • Increase sales through more impulse purchases
  • Keep your customers coming back more often through stronger associations with your brand
  • Increase the concentration of your staff
  • Create more fun at work!


Which fragrance should I use?

Different fragrances have different effects on people. Some of it is personal. If you have a good memory with a specific fragrance, you will like that fragrance more than someone who does not have that memory. However, there are some general trends. Lavender provides better concentration and people work longer productively. A citrus scent is related to harder physical work and faster reaction time. For cognitive tasks, stimulating fragrances such as coffee are very suitable. The effects on customers do not have much to do with which scents are used. It is especially important that the customers experience the fragrance as pleasant.


How do I use scent marketing in my shop?

There are many ways to use scent marketing in a shop. Basically it is nothing more than spreading specific fragrances through your shop. Candles, sprays or scented sticks all have an effect. However, the best method is a scent appliance. A good fragrance appliance spreads the scent in a very constant way through the space. This is due to the cold mist method with which it works. The appliance converts liquid essential oil to a cold mist. As a result, it does not sink to the ground but spreads throughout the room. This way, you make sure that all the nooks and crannies in your shop have the scent you want.


Scent marketing shop


Which fragrance machine should I have?

For larger shops, the Scent experience is the best choice. This appliance is suitable for spaces between 100 and 800 square metres. So not only is it very powerful, the possibilities are also very diverse. Thanks to its many possible settings, you don’t have to limit yourself to just one scent. You can create your own scent plan to achieve your goals. If you want to do scent marketing, but you have a smaller shop, choose the Smartscent. This is a smaller version with a range of up to 100m2, but does offer all the benefits of retail scent marketing.

Scent marketing wellness, why?

Scent marketing wellness, why?

The number of people going to a wellness centre to relax is increasing rapidly. Scent marketing helps your wellness resort to distinguish itself and to make the experience unforgettable for your guests. This has to do with the special connection between scent, emotion and memories. It helps people relax, makes them happier and helps them remember your centre. We explain the effects of scent marketing in wellness and how to use it to achieve your goals.


What effects does wellness have on people?

Many people go to a wellness centre to relax. A day of relaxation. This relaxation also has significant health effects. For instance, it has been researched that people who come out of a wellness centre have a significantly lower cortisol level than when they enter the resort. This means that people experience less stress when they go to a wellness centre. Also, according to a Japanese study, a spa day makes people feel happier. Naturally, you want to maximise these benefits. Scent marketing in your wellness centre can help you take these effects to a higher level.



Scent marketing wellness



Why is wellness necessary?

Everyone has experienced stress. Before an important meeting at work, a sports competition or an exam. This does not have to be a bad thing at all! Stress gives us a push and helps us to perform optimally. We call this acute stress. However, if the stress moments follow each other constantly and we have too little rest, chronic stress arises. Unfortunately, this is becoming increasingly common nowadays and has negative health effects such as poor sleep, headaches and anxiety. To counteract this, relaxation is very important. Unfortunately, this is becoming increasingly difficult in our modern society. We can be reached 24 hours a day, receive stimuli from social media or quickly watch a series on the train. That is why you often get new ideas in the shower, as you have nothing to do. As a wellness centre, you play an important role in helping people relax. Scent marketing goes hand in hand with wellness.


Why scent marketing in my wellness centre?

What we smell always seems to pass us by. We are much more aware of what we see and what we hear. That is why many people think that scent marketing does not add much to wellness. Nevertheless, our sense of smell is perhaps our most important sense. It is probably the first sense to have evolved and is located in our brains right next to the part that processes emotions. Hence, it has the greatest impact on how we feel and behave. Think about how you feel when you walk past the fresh bread section in the supermarket. So, if you want people to relax in your wellness resort, you’d better take scent marketing seriously!


Do people return more often to a wellness centre with scent marketing?

The short answer is yes. Smells have a much stronger impact on our memories and emotions than our other senses. So, if your wellness centre smells good, this has a greater impact on how people experience it than what it looks like or what music is playing. If you spread a distinctive fragrance, people will also associate this fragrance with their enjoyable day at your centre. Every time they smell that fragrance, they think of the wellness centre. It also works the other way round. If it smells bad, maybe due to sweat or other body odours, people will not like to come back to your spa, no matter how nice the rest of the day was. Scent marketing is therefore an essential part of your wellness centre.


Which scents are most effective?

There is no single scent that is best in all areas of the spa. It all depends on what you want to use scent marketing for in your wellness centre. It has been proven that the scent of lavender makes people feel fresher and more relaxed. The scent of lemon has completely different effects. It stimulates the production of dopamine and serotonin enormously. These two substances make us feel more content and happy and less anxious. So, there are several things to achieve with scent marketing your wellness resort! It is even possible to influence the buying behaviour of people in, for instance, your restaurant.


  • Let your guests relax
  • Your wellness centre will be better remembered.
  • Your guests feel more satisfied and happy
  • Associate your resort with positive emotions
  • Remove bad body odours effectively.


How does scent marketing work?

Professional scent marketing in wellness works with the help of a scent diffuser. These are machines specially designed to bring fragrant essential oils into the air for us to smell. This is done with the cold mist technique. Because the machine puts the scent into the air as a mist, it does not sink to the ground but spreads itself through the air. This way, the scent stays longer and you are more economical with your oil!


Scent marketing wellness


What scenting machines are there?

Scent marketing in the wellness area comes in many shapes and sizes. For the larger spaces, like the lounge and the restaurant, there is for example the Scent Experience. This machine is perfectly suitable for spaces between 100m2 and 800m2. This device also has many setting possibilities. Because of this, you are not limited to a single scent, but you have the possibility to compose a real scent plan.


For the smaller spaces, think of salt baths or saunas, the Scent Experience is not necessary. Here we recommend the Smartscent. This device is suitable for spaces up to 100m2 and spreads a consistent fragrance. So you don’t have to worry that the fragrance will diminish. Your guests will continue to enjoy it.

Scent marketing for hotels

Scent marketing for hotels

Scent marketing for hotels is the latest global trend. It is the answer for the hotel industry in its quest for innovation. Offering scent experiences has become a differentiating element that travellers value highly and it enhances the customer experience. Scent marketing allows your hotel to not only strengthen its brand identity, but also to increase sales and improve the customer experience. But what is scent marketing for hotels? And what are the pros and cons? Read on to find out all about scent marketing for hotels.


What is scent marketing for hotels?

Imagine a guest entering your hotel lobby and immediately sensing a scent that triggers a mechanism in his or her brain. At that moment the subconscious registers the smell as a very powerful and memorable memory.


In milliseconds, you turn the image of your hotel into a powerful memory, creating an even more lasting connection with the hotel brand. Strengthen the marketing concept of the hotel brand by bringing aroma-client-brand together.


Studies show that a person remembers 35% of what they smell. Because smell and memory are connected to the brain, people are able to remember smells and aromas for years. Therefore, this sense is fundamental to any marketing strategy.


Some studies show that memories triggered by smells can be stronger than those by images or sounds. Based on this principle, scent marketing for hotels is a stimulation technique that uses the sense of smell to convey lasting sensations to consumers.

What are the advantages and disadvantages of scent marketing for hotels?

A key benefit of this marketing technique is that it transcends the boundaries of distance. That is, no matter how far away your customer is from the hotel, he will vividly remember the experience sown by the brand. This strengthens the bond that has been created. We call this phenomenon the butterfly effect. No wonder hundreds of luxury hotels are already harnessing its power.



Other benefits of scent marketing for hotels include:

  • Creates a positive first impression with travellers and influences their entire experience
  • Relates to guests’ holidays, creating memorable memories
  • Can stimulate the consumption behaviour of the guests, especially in the hotel room, in the restaurant and in the wellness areas
  • Influences the satisfaction of travellers, especially in the area of housekeeping services


A disadvantage is that – like all forms of marketing – it requires investment and planning. You may want to use scent marketing only in common areas with the same scent that identifies your hotel. On the other hand, you might consider using distinctive scent marketing in different parts of the hotel. For example, one scent for the rooms, another for the lobby, another for the restaurant, etc. Of course, the costs and planning required will vary. But in both cases the results are worth it.


Which fragrance diffusers are suitable for a hotel?

When choosing an odour diffuser for your hotel, it is important to take into account, firstly, the size of the premises. And secondly, the capabilities and power it offers. At Extreme Air Products we have two professional fragrance diffusers that are ideal for scent marketing: the Scent Experience and the Smartscent.


Our Scent Experience diffuser is ideal for large spaces such as the lobby and restaurant/bar. This professional fragrance diffuser is designed to influence the perception of scent in spaces between 100 and 800 m2. Moreover, the possibilities of this product are almost unlimited. Different fragrances have different effects. So choose the fragrance that is most suitable for the location. When choosing a fragrance diffuser, it is important that you take into account that it is easy to use. After all, many employees in the hotel will have to work with it, so it is essential that it is easy to use. Then the Scent Experience is exactly what you need. It is easy to use and can be adjusted very accurately. You can also determine exactly how strong the system is and what times and days it is active.


scent marketing for hotels

Scent Experience


For smaller spaces, on the other hand, we recommend our Smartscent scent diffuser. This can be the perfect scent diffuser for spaces such as bedrooms and meeting rooms. It is also ideal for wellness facilities such as massage practices, group practices, yoga studios, etc. With the Smartscent you can easily create the desired fragrance experience in rooms of 60-80 m2. It consists of a cold mist technology. The aromas based on essential oils are gently introduced into the room. The desired intensity can be adjusted with a slider.


Scent marketing for hotels also requires a scent neutraliser

One should not forget that the goal of scent marketing for hotels is to create an unforgettable experience. In addition to increasing customer satisfaction with their stay. While the perception of pleasant odours is fundamental to improving the guest experience, neutralising bad odours is equally, if not more, important! We have all experienced how a bad smell can sour our stay, making us forget all the good things the hotel has to offer.


A scent cannot mask an unpleasant smell, it can even make it worse. Therefore, in these cases it is essential to have an odour neutraliser. At Extreme Air Products we recommend our odour Neutraliser. Thanks to its patented neutralising cartridges, it can eliminate even the worst odours. It is ideal for restaurants (e.g. preparing fish), for the hotel gym or fitness room, as well as for communal bathrooms, laundry or smoking areas.


6 scent marketing tips for hotels

Good use of scent diffusers can make the difference between the competition and your hotel. It is not surprising that most 5 star hotels already use this effective technique. Here are some tips on how to make the most of scent marketing in your hotel:


  1. Plan a good strategy. Will you use it only in common areas or will you use it in all rooms?
  2. Not all fragrances are suitable. Different situations need different scents. Think about what feeling you want to convey in the different rooms, and choose an appropriate fragrance.
  3. Use scent marketing. This is to offer a plus to your services. For example, use the smell of jasmine in meeting rooms. According to the latest studies, this smell increases concentration!
  4. Play with the illusion. Good cleaning is not always synonymous with a clean and fresh scent. A lemon scent or a fresh cotton fragrance is more effective.
  5. Think about the pleasure of your guests. Neutralise bad smells where necessary. And promote pleasant fragrances in your hotel’s restaurant (making the stay more pleasant and increasing sales), in the spa or in the lobby.
  6. Create tranquillity in your hotel rooms. Use a pleasant, soft lavender fragrance in the rooms to promote calmness among your guests.

By following these tips, you will ensure that your hotel guests have a wonderful stay.

An air purifier, how healthy is it?

We care about clean air

solutions for indoor air quality

Quick to: advice and product

An air purifier, how healthy is it?

Whether an air purifier is healthy is a frequently asked question. On the one hand, you hear stories about the harmful effects of air pollution. People say air purifiers help against this. On the other hand, you hear bad things about the effects of ionisation, ozone and dirty filters. Some even go so far as to claim that an air purifier is unhealthy. What should you believe? Here we explain how healthy an air purifier is. But also what the risks are and what you should pay attention to.


What is an air purifier good for?

The biggest health benefit that an air purifier brings is, of course, the removal of air pollution. Air pollution, especially by fine dust, is a big problem in the Netherlands. Fine dust is a collective term for all kinds of different particles smaller than 10 micrometres. Soot, Sahara sand or even microplastics are examples of these. The smaller these particles are, the further they enter our bodies when we inhale them and the greater the damage to our health. This is because the lungs do not filter the very smallest particles and, as a result, they can directly enter your bloodstream.


The RIVM estimates that people in the Netherlands live on average 13 months shorter thanks to particulate matter. So an air purifier is definitely useful! Yet sometimes you hear that an air purifier is unhealthy. This would mainly have to do with ozone and polluted filters.


Air purifier with ionisation, healthy or not?

Many air purifiers have the option of adding an ioniser. An ioniser creates negatively charged ions by means of electricity. These ions easily bind to other particles in the air. This way you can easily destroy viruses and other organic material and your air cleaner will keep you healthy. An air purifier with ionisation also works better against fine dust. Ionisation causes particles to clump together in the air. This creates larger particles that sink to the ground due to gravity and thus disappear from the air circulation. Unfortunately, after some time, these particles re-enter the air. Another disadvantage of this method is that the ions also react with oxygen, creating ozone.


Healthy air purifier with ionisation


Are ozone emissions from an air purifier unhealthy?

Ozone is a gas with three oxygen atoms that easily reacts with other particles. This is why it can be dangerous. It is created when an oxygen molecule binds an extra oxygen atom. Ions eventually form loose oxygen atoms through various reactions, and thus also ozone. When we breathe in ozone, it reacts with our body cells and irritates them. That is why ozone is known as a toxic gas. Long-term exposure to too much ozone causes a variety of health problems. This is why you sometimes hear that an air purifier can be unhealthy. A carbon filter removes ozone from the air. The ozone binds to the carbon and leaves normal oxygen behind. However, it is important to replace this filter regularly.


What are the consequences of ozone?

Ozone has many negative health effects, such as:

  • Irritation of the airways
  • More asthma
  • Reduced lung capacity
  • Chest pain and increased coughing
  • Greater chance of inflammation in the airways

Research shows that negative ions do indeed purify the air. Unfortunately, the negative effects of ozone are also significant. It also appears that prolonged exposure to ozone has more risks than short term exposure to a high concentration. Whether an air cleaner is healthy therefore depends on how many ions it introduces into the air circulation.


Can ionisation before the filter make the air cleaner healthy?

You must therefore consider the ozone production of an ioniser. An important difference is whether the ioniser is located before or after the filter. If the ioniser is located after the filter, the ions end up in the air and eventually react with oxygen to form ozone. However, if the ioniser is in front of the filter, the ions only react with the particles that are blown towards the filter. Thanks to the electrical charge of the filter, it absorbs all ions. The ionisation process thus remains limited inside the air purifier. Because of this, ultimately no negative ions enter the air you breathe and no ozone forms. A healthy air purifier therefore has ionisation before the filter and not after.


Which air purifier is healthy?

A good example of an air purifier with ionisation before the filter is the EA30. Thanks to its combination of a fine mesh Hepa filter and effective ionisation, this device removes no less than 99.98% of pollution from the air. Thanks to the ionisation, fine dust particles are electrically charged when they reach the filter. As a result, the filter catches them better and there is less pressure loss. Noise and energy consumption remain limited. So this is an excellent choice for most living rooms and bedrooms.

Filter full, health risk?

There are people who claim that your air purifier sends unhealthy particles into the air when the filter is full. And these people are right! However, these are the same particles that would be in the air if you hadn’t had an air purifier in the first place. If you seldom change your filter, it gets clogged up with all the particles it picks up. This causes it to lose some of its effectiveness and the situation slowly returns to the way it was without an air cleaner. So a dirty filter can never make your air worse than it was originally. This problem is also easy to prevent by changing the filters regularly.


Healthy air purifier, when is it good and when is it not?

An air purifier delivers many health benefits. By removing fine dust, air purifiers make you a lot healthier. However, you must be careful of too much ozone. Ozone affects your lungs and causes a lot of health problems. So make sure you buy an air purifier with ionisation before the filter. Dirty filters never cause health damage, but by replacing the filters regularly you maintain their effectiveness.

Professional scent diffuser | What can it do?

Quick to: advice and product

A professional scent diffuser, what is it and what can it do?

We all smell, 24 hours a day. Scenting directly determines our image of the environment. Because certain smells evoke strong memories of the past. That is why scent marketing has been on the rise for years. But how does a professional scent diffuser work? And for which purposes do you use scent marketing? In this blog, we will provide you with all the facts about professional scent diffusers and essential oils.


Professional diffusers, why is it useful? Smell is perhaps our most underestimated sense. We are all very aware of what we see and what we hear, but what we smell seems to pass us by. Yet nothing could be further from the truth! Smells have a huge influence on how we feel, how we behave and what we think of other people (source). Some people experience this even more strongly than others. Also to achieve professional goals, people increasingly use scent marketing. For instance with a scent diffuser.


Scent marketing with professional scent diffuser


Our brain and scent, what about it?

Our brain processes odours and emotions right next to each other. Therefore, smells have a stronger emotional response than, for example, sounds or images. A scent diffuser takes this into account. Because people remember memories better when emotions are linked to them, scent also plays an important role here. Many people are not aware of the effects that different aromas have on our lives. But when we lose our sense of smell, as many of us unfortunately have experienced through corona, we notice how important it is. Can these effects be applied in a professional way with a scent diffuser?


What does a professional scent diffuser mean for me?

Yes you can! Many organisations are already using professional scent diffusers to achieve their goals. For example a hotel lobby where the smell of fresh linen makes guests feel at home, but there are many more goals possible with scent marketing. It has been shown many times that the right aromas strengthen the buying incentive in shops. Also, people remember your brand a lot better when it has a distinctive smell. These effects do not even have to be consciously noticed by people. Research has shown that people trust each other more when the smell of freshly ground grass is in the air, even when people do not consciously notice it! So a professional scent diffuser is very versatile:

  • Increase the sales incentive in your shop
  • Make people relax even more in your massage parlour
  • Stimulate the productivity of employees with stimulating fragrances
  • Eliminate bad smells in your nursing home with scent neutralization
  • Don’t be forgotten thanks to a recognizable scent


A scent diffuser in a professional environment. Is it useful?

That odours have a real effect on people should be clear by now. But that these effects are very large is increasingly shown by scientific research. Many studies have been done to measure these effects. It appears that customers stay 27% longer in a shop if there is a strong, pleasant fragrance. The number of impulse purchases also increases significantly. In a supermarket, for example, a strong, pleasant fragrance increases this number by as much as 43%! People’s willingness to buy increases even if it smells good in a room. For an unknown product, people are sometimes even prepared to pay 40% more. A professional scent machine works wonders!


Smartscent, an ideal professional scent diffuser


Professional scent diffuser in the care sector

A fine aroma does not only have commercial advantages. A scent diffuser also contributes to a pleasant environment. In healthcare, a fine aroma is of great importance to residents, visitors and employees. The smell of wounds, faeces or incontinence is very unpleasant. For residents, this reduces the pleasure of living and even the quality of sleep. Care workers who have to work in a foul odour every day have less job satisfaction and this even leads to a higher outflow. A professional scent diffuser can be an important part of the solution.


Essential oil, necessary for a professional scent diffuser?

Most scent diffusers work on the basis of a fragrance oil, also called essential oil. Although this liquid is called an oil, there are no fats in it. It is a liquid composed of many different scents. Because there are thousands of fragrances, each essential oil is personally composed by a professional. This way, our diffusers provide the best possible experience!


How does a scent diffuser work?

Different aromas have great effects on people. There are many ways to spread the desired fragrance in a room. Candles, scented sticks or sprays can all be used, but the best method is with a scent diffuser. A professional scent diffuser works with the so-called cold mist technique. Here, the liquid un-vaporised fragrance oil is dispersed into the air, creating a cold mist. This mist spreads evenly through the room and does not sink to the floor. The fragrance therefore lingers longer and the oil lasts longer!


A good example of a professional scent diffuser is the Smartscent. This device is easy to operate. Its strong fragrance oil and effective design make it an excellent choice for improving business results with scent marketing.

An air purifier for MCS – how effective is it?

One in every four Americans suffer from MCS (Multiple Chemical Sensitivity) when exposed to common chemicals. As shown in a recent study of the University of Melbourne. How effective is an air purifier for MCS? In Europe, MCS is now also regarded as an emerging new disease. Due to MCS environmental nature, experts on the matter have much discussed the role an air purifier could play in treating this disease. But what is the best air purifier for MCS? Continue reading to know more.

What is MCS?

Multiple Chemical Sensitivity is an environmental disease, characterized by increased sensitivity to common low-level chemicals. The European Parliament has recently defined MCS as a new disease due to the pollution in the environment increasing by 300% the prevalence of diagnosed MCS in the last decade. Experiences and tests on air purifiers for MCS show positive results.


Airpurifier for MCS symptoms



It is not always easy to identify the factors responsible for the manifestation of hypersensitivity. Indeed, many products used in our daily life can be responsible, making their identification often complex. Among the volatile organic compounds that have the greatest impact are:

  • fresh paints
  • pesticides
  • perfumes
  • cosmetics
  • building materials and industrial fumes
  • cleaning products

Exposure to these products can be respiratory, digestive, or cutaneous.
Consequently, significantly altering the quality of life of the person. Patients are within their own homes intoxicated. Could an air purifier for MCS alleviate the symptoms?

Can an air purifier help MCS?

The treatment of MCS is quite complex. The experts agree that the best treatment is addressing the environmental factors that cause the hypersensitivity. Given that we spend an average of 80% of our time indoors, removing chemicals and their fumes from your home is essential to treat MCS. Thus, an MCS air purifier is crucial for treating it (as it has been shown in the latest studies).

Buying an air purifier for MCS. What should I look for?

A good air purifier to treat MCS has an HEPA filter and emits no ozone. You should also consider the noise it produces and where you will place it.  As well as being essential to take into account the energy consumption. For a bedroom, the EA15 is ideal. This device produces a decibel level of only 25 dBA. Thus, almost inaudible to humans. The EA15 also has an extremely low energy consumption (using only 10W at its max). This is a very economical model compared to other air purifiers. Furthermore, our purifiers do not emit ozone, so you can rest assured when using one of our air purifiers with MCS.

Air purifier for MCS, which one do you need?

Depending on your work environment, you can be exposed to many chemicals, as it is the case, for instance, for hair salons, nail salons and industrial factories.

It is very important to protect your workers from such exposures to avoid problems such as absenteeism.

  • Latex-free paper face masks or cotton masks and filters and/or masks with a high-efficiency particulate absorbing filter (HEPA) and activated carbon filters.
  • An active carbon water purifier with a percentage of rubber gaskets < 3%.

asthma airpurifier


As defined by the Mayo Clinic, asthma is a condition in which your airways narrow and swell and may produce extra mucus. This results in a breathing difficulty and coughing, a whistling sound when you breathe out and shortness of breath. It is one of the most common chronic illnesses in the world, with over 300 million people worldwide affected by it. The Netherlands, for instance, is the country with the highest concentration of asthmatic children in the world.

What factors cause asthma?

There are many factors that can cause asthma, but they boil down to either a genetic predisposition or to the home or work environment; these include:

  • allergens present inside the home (dust mites, moulds, dander) or in the workplace
  • outdoor allergens (pollens and moulds)
  • respiratory infections
  • respiratory irritants (tobacco smoke, air pollution, irritants in the workplace)
  • cold air
  • physical exercise
  • certain medications (anti-inflammatory drugs)

Can an air purifier alleviate or prevent asthma?

To improve their health, asthmatics must consult their doctor to be prescribed a basic treatment (cortisone, Ventolin). However, there are additional strategies that one can take to alleviate the symptoms at home and the workplace, being the use of an air purifier the most important one.

Permanent use of an air filter in the bedroom that traps fine dust particles with diameters smaller than 2.5 micrometres can not only significantly improve breathing in children with asthma but prevent its onset, according to a new study by US and Chinese scientists.

Buying an air purifier for asthma. What should I look for?

What is important when we consider buying an air purifier for an asthmatic, is that it has an HEPA filter. Also, the noise it emits and where we will place it. As well as not emitting ozone. For a bedroom, the EA15 is ideal. This device produces a decibel level of only 25 dBA. That is almost inaudible to humans.

Asthma in the workplace – what causes it?

There are two types of work-related asthma. There is occupational asthma, which is asthma induced by substances present in a particular work environment. And work-aggravated asthma, which is pre-existing or recently developed asthma whose manifestations are worsened.

Childhood asthma in the Netherlands

In the case of children, it can be diagnosed from the age of 3 or 4 years, when the development of the pulmonary alveoli is fixed. According to a study published in the Lancet, one in every five children in the Netherlands suffers from pollution-induced asthma. That’s about 100,000 children up to the age of 14 total in the country, and the numbers are worsening due to pollution from the transport sector.

Other strategies to fight asthma

  • Keep your windows open when it’s safe to do so to prevent locking irritants into rooms (especially when air purifiers aren’t on). Create a stronger cross draft by opening windows on opposite sides of the room if possible.
  • Vacuum often.
  • Regularly change air filters to properly maintain HVAC equipment and maximize effectiveness
  • Use an exhaust fan in the kitchen. Switch it on before preheating the oven or firing up the burners and leave it running for a few minutes after you’re done cooking.
  • Minimize the use of candles or wood fires and ban smoking inside the home.
