what does an air cleaner do?

air purifier provides 99.97% clean air

The air in an office or classroom can easily contain five times as many harmful substances as the air outside. Adequate ventilation is therefore important. But when it is cold outside, the windows often remain closed. In addition, the outside air dilutes the amount of harmful and undesirable substances in the inside air, but does not remove them.

With the increased attention to pollen allergy, the harmful effects of fine dust and the spreading of germs such as the coronavirus via aerosols, there is a great deal of interest in air cleaning in commercial buildings, offices, restaurants, treatment centres and schools. The high costs of a central air-conditioning system are often a problem. However, there is a much simpler, cheaper and more effective solution in the form of mobile air cleaners.

Modern air cleaners remove 99.97% of polluting and disease-causing particles from indoor air and render them harmless. Technological developments have led to equipment that requires a limited investment, requires little maintenance and can be used plug & play immediately for optimum air cleaning.

SUViS subsidy for ventilation of schools

Closing date SUViS extended to 30 April 2022

The closing date of the current application round for the Specific Payment Scheme for Ventilation in Schools (SUViS) has been extended from 31 January 2022 to 30 April 2022. The reason for this change is that the payment ceiling has not yet been reached on 31 January.

Trusted air cleaners

AIR8 on the list of trusted air cleaners

AIR8 air cleaners have been included in the list of trusted air cleaners by Horeca Vlaanderen. The interest group for Flemish hotel and catering entrepreneurs submitted frequently asked questions about air treatment systems to the government.

Ventilation in the classroom

Little progress with ventilation in the classroom'.

In the area of ventilation in the classroom, little has actually changed in the past year, experts complain. Professor of Building Services Innovation Atze Boerstra of Delft University of Technology: "The Ministry of Health, Welfare and Sport has now issued a guideline on ventilation. I could have done that last year. We are really losing time.

Our 6-stage filtration

What makes the AIR8 air cleaner so good?

One HEPA filter is not like another

HEPA is an abbreviation for high-efficiency particulate air and stands for air filters that capture a minimum of 85% of all dust particles from 0.3 micrometer (µm) upwards. Incidentally, particles smaller than 0.3 µm are also captured better than the indicated percentage, but that is a very technical story. It is important to know that there are different classes of HEPA filters.

HEPA filter classes

HEPA classRetention (total)
E10> 85%
E11> 95%
E12> 99,5%
H13> 99.95%

The AIR8 air purifier uses a HEPA H13 filter, which is exceptionally high compared to many other air treatment systems.

These situations call for a higher air cleaning factor

Air cleaner corona

The corona pandemic has accelerated the purchase of air purifiers. It is an extra measure on top of the distance and hygiene measures advised by the government.

Our medical grade HEPA13 filters remove 99.97% of all harmful particles from the air, including virus and bacteria particles. This means that even the coronavirus is captured and rendered harmless.

Research has shown that this reduces the infection pressure in classrooms and gyms significantly decreases. Let us be clear: if someone with a corona infection is talking to others or 'breathing in' from a short distance over a long period of time, air purification does not prevent virus transmission.

Medical mask

The coronapandemic has made it impossible to avoid a mouth mask.
Incidentally, mouth caps have become the most common collective name for what is known in healthcare and industry as a mouth mask. The recommended mouth caps are worn over your mouth and nose (and not over your chin).

Where face mask is mandatory

During the lockdowns, mouth guards are mandatory in public life in various places. Where exactly depends on the type of lockdown.
On the website of the Government you will find Up-to-date information on the requirement to wear a mouthguard. Especially in shops, public transport, hairdressing salons, beauty salons and public buildings it has been compulsory to wear a mouth mask for the past two years.

Medical mask II and IIR

Medical mouth masks meet the applicable quality and safety requirements. If a mouth mask is non-medical, it is not clear to what extent it protects.
There are different types of medical masks. The most common in everyday practice are type II and type IIR mouth masks. These stop the droplets from falling when you breathe out, talk, shout and sing. Thus, they prevent you from infecting anyone if you are carrying the coronavirus. Also, type II and type IIR medical masks stop droplets up to a certain size, so that even as a carrier you are better protected against corona and other airborne viruses.

FFP2 mouth mask

FFP2 mouth masks protect against aerosols (very small droplets) better than medical mouth masks. This is because these mouth masks fit around the face on all sides. Because of their shape, they are popularly called coffee filters.  
FFP2 mouth masks may also be used during lockdown. The protection is better than with a medical mask, but wearing an FFP2 mask for a long time can lead to complaints such as headaches, fatigue and tightness in the chest.
For people with a lung disease or pregnant women, it is therefore not recommended to wear an FFP2 mouth mask. For vulnerable people, however, the (brief) wearing of an FFP2 mouth mask can be considered.

Air purifier test

AIR8 air cleaners are subjected to extensive tests in the factory. They have also successfully passed many practical tests.

For example, AIR8 supplies many mobile air cleaners to German educational institutions, after the schools first installed the air cleaners on a trial basis. Also the effectiveness in school classes was demonstrated by the Goethe Institut.

Also in the Netherlands, schools, companies and institutions can apply for an air cleaner on a trial basis.

The reason I bought this 'air washer', as I call it, is that I want the best for my guests. I want them to feel good here, to be able to go about their business without having to worry about things like air quality. The ventilation was already well organised, but now it's even better.

The air quality in our centre was already good. But what this device managed to do in one night is truly unimaginable. That's why I immediately bought one for my home. I'm really happy with it and so are the people who train here.

Air cleaner and humidifier

AIR8 does not have a model that is an air cleaner and a humidifier in one. This was done deliberately because these are two very different functions that have nothing to do with each other. The same applies to the combination of air cleaner and air conditioner.
This combination of functions only leads to higher energy consumption and a higher failure rate. Usually, the combined functions are not needed at the same time.
We have chosen to focus entirely on and specialise in air cleaning, in order to achieve the best possible results at the lowest possible cost.


It is striking that after the initial purchase for their company, several of our customers later order a mobile air purifier for their own bedroom. Especially people who sleep restlessly or snore lightly once in a while. We get positive feedback from these customers about the effect of air cleaning on their sleep.

Calculating air cleaning capacity

air cleaner CAPACITY

How to calculate the required capacity of your air cleaner

To determine which air cleaner you need and how much, the most important thing is the required capacity.

The decisive factors for this are the volume of the room and the air change rate (ACH). The number of times per hour that the air in the room must be filtered and decontaminated depends on the average number of people present in the room and any circumstances where there is extra contamination. Think, for example, of dental practices where an above-average quantity of aerosols (very small water droplets) is floating around. More exceptions can be found in the left column.

Building code and health and safety standard

In most cases, you can work with an ACH of 4, as advised by Harvard Healthy Buildings (authority in the US) and the World Health Organisation (WHO). The capacity calculated in this way is usually above the Buildings Decree 2012 standard and the Occupational Health and Safety Act standard, because these take into account the occupancy rate in a room. However, this has the risk that, with relatively few people in a room, not all the air is drawn in by the air cleaner, resulting in dead spots where the air does not circulate sufficiently.

Multiply the ACH of 4 by the volume of the room in cubic metres and you get the required air cleaning capacity.

AIR8 air cleaner capacity

For our models, this means the following:

26oi NANO - capacity = 260 m3/hour - divided by 4 this means suitable for a room up to 65 m3. With a standard ceiling height of 2.5 metres, this means a floor area of 26 m2 (e.g. 4 x 6.5 metres).

280 NANO - capacity = 280 m3/hour - divided by 4 this means suitable for a room up to 70 m3. With a standard ceiling height of 2.5 metres, this means a floor area of 28 m2 (e.g. 4 x 7 or 5 x 5.5 metres).

720i EDGE - capacity = 720 m3/hour - divided by 4 this means suitable for a room up to 180 m3. With a standard ceiling height of 2.5 metres, this means a floor area of 72 m2 (e.g. 8 x 9 metres). This model has no UV disinfection, but does have the high filtration rate of 99.97%.

1200i PRO - capacity = 1200 m3/hour - divided by 4 this means suitable for a space up to 300 m3. With a standard ceiling height of 2.5 metres, this means a floor area of 120 m2 (e.g. 10 x 12 or 6 x 20 metres).
