What is an air purifier used for?

An air purifier treats the air present in a room with the aim of filtering and destroying the various sources of pollutants. Indoor air quality is therefore greatly improved.

What pollutants are treated by our air purifiers?

Elimination of biological pollutants

Elimination of chemical pollutants

Our different air purification methods

As specialists, we offer different purification methods. Each method has its advantages and disadvantages.
The fact of offering our customers several purification methods allows us to respond to all requests with regard to the purification of indoor air.

HEPA filtration

A HEPA filter is a high efficiency filter ( High Efficiency particulate Air ).

A HEPA filter is capable of filtering at least 99.97% of particles with a diameter greater than 0.3µm.

Activated carbon filtration

It is a carbon material that has been treated to increase its absorbent properties .

Its very porous structure gives it a high property of fixing and retaining pollution particles and gases .

UVC lamps

UVC rays destroy nucleic acids by breaking down the DNA and RNA of microorganisms.

This action has the effect of rendering these micro-organisms incapable of reproducing and of infecting a host.


Disinfection by oz one is particularly effective in decontaminating objects and surfaces.

Ozone is a substance made up of three oxygen atoms (O3).
Due to its instability, the third molecule of oxygen attaches itself to all pollutants .


Ionization consists of diffuse negative ions directly into the ambient air.
Due to their polarity, negative ions are highly reactive and attach themselves to pollution particles.
So they go either disintegrate them , or weigh them down and knock them to the ground.


Photocatalysis is an advanced oxidation technology , which relies on the activation of a semiconductor (titanium dioxide) by light (UVC).

This helps to destroy chemical pollutants and biological pollutants .

The answers to your questions:

It is, in fact, very difficult to prove the effectiveness of an air purifier . As the market is still immature, there are no standards that guarantee the effectiveness of air treatment. On the other hand, the techniques used have standards and efficiency reports on which we can rely.

For example, HEPA filters have been around for many years and meet European standards that prove their filtration efficiency. Similarly with UVC lamps, manufacturers have validated efficacy reports on the disinfection effectiveness of UVC radiation .

The other way is to carry out tests in a private laboratory which simulate the real conditions of use. Our air purifiers have several different laboratory tests that prove their effectiveness in purifying indoor air.

Some of our air purifiers are equipped with air quality sensors that tell you the indoor air quality in real time.

Whether you are a professional or an individual , an air purifier will be very beneficial for your health and that of those around you.

For individuals,
Respiratory allergies affect more and more people because of our way of life. The air in our homes is 8 times more polluted than the air outside (due to all the chemical pollutants present in the furniture, the building and all the household products) and we spend 80% of our time indoors . Even if for the moment, you do not suffer from respiratory allergy , it is better to be safe than sorry!

For professionals,
In our workplace, we encounter the same air pollution problems as in our homes , but to this is added the risk of virus transmission! The transmission of viruses or bacteria is the leading cause of sick leave for employees. Indeed, the risk of transmission between patients/customers and staff is very high !
Take care of yourself, your family and your customers, everyone will thank you!

It depends on the purifiers, and especially on the volume of air treated per hour.

This remains minimal, moreover our air purifiers intended for houses, apartments and offices have several adjustment speeds which allow you to adjust the power and therefore reduce noise . They are even equipped with a night mode which allows you to be very quiet with all the lights off!

There is no rule, it depends on your needs in terms of air treatment.

If you want to reduce chemical pollutants in a house, you can leave it running in automatic mode during the day (it will adapt the speed according to the pollutants present in the room.) and switch to night mode for the evening.

If you want to reduce the transmission of viruses , it is useless to leave it on all night, in empty rooms.
For a professional who wishes to reduce the transmission of viruses and bacteria, we recommend turning on the purifier one hour before the arrival of the first customers/patients and turning it off one hour after the departure of the last customer/patient . Air purifiers are an effective complement to barrier gestures , however natural ventilation is of course recommended several times a day.

The cost of maintenance varies greatly depending on the technology used and the use made of the air purifier.

Air purifiers equipped with filters ( HEPA , activated carbon, etc.) have slightly higher maintenance costs than UVC . By its nature, a filter retains pollutants , and therefore begins to clog over time. It is difficult to give a filter change frequency, as it can vary greatly depending on where the purifier is installed. But on average a filter lasts between 6 months and 1 year.

Our UVC air purifiers have very low maintenance costs. Lamp life averages 9,000 hours!

All our air purifiers equipped with HEPA filters have a control screen with a filter change indicator.

As for the air sterilizers with UVC rays , they have an hour counter that lets you know when the UVC bulbs need to be replaced (based on the time of use) .

For models of air purifiers intended for individuals , changing the filter is very simple . It happens in a few minutes. However, it is necessary to take precautions. It is advisable to change the filter outside with a mask and gloves.

For models of UVC purifiers for professionals , it is preferable for our company to change the UVC bulb to avoid any risk of contact with UVC rays. If your technical staff wishes to carry out the manipulation, it is advisable to contact us beforehand for a quick training.

UVC rays are very powerful and must not come into contact with the skin or eyes.
However, UV-C lamps have been in use for many decades and only a small number of incidents caused by accidental exposure or misuse occur.
All our air purifiers equipped with UVC lamps meet all the standards (IP 20) which certify that no UVC rays come out of the device.
This therefore poses no danger to the people present in the room.
In case of fall of the device, it is preferable to contact us so that we carry out a control of the purifier.
