An indoor air purifier ensures the filtration of the indoor air, of an enclosed space, which it captures to release a depolluted air.

A distinction must be made between a professional model and a domestic device, both of which do not guarantee the same air treatment and comparable overall performance levels.

Attention should also be paid to safety: that is, the ability of an air cleaner to generate no secondary pollutants itself.

What are the main purposes of an air purifier?

Fight unpleasant odours, pollution and particles but also tackle the spread of viruses, thanks to medical-grade HEPA filters, for professional models such as EOLIS Air Manager.

What are the objectives of an air purifier?

Limit the spread of harmful residues or allergic or even viral elements, prevent asthma or allergy problems linked to poor indoor air quality in people at risk (children, elderly or sensitive people).

An air purifier, not to be confused with an air ioniser or an air humidifier, can be used in a preventive and/or curative way, at home, in closed offices, open spaces or coworking places, shops, hairdressing salons, hotels or restaurants, medical and para-medical practices…

It concerns people or companies with no particular problems but who wish to protect their health, that of their entourage or employees, for example for the latter in a situation of resumption or continuity of the activity. The indoor air purifier is, in this sense, in phase with the current health and societal issues related to air quality. Both with regard to PM2.5 fine particle pollution and the risks associated with the propagation of viruses by air or aerosols.

How does an air purifiers work?

The purifier filters the indoor air and purifies it, removing the various sources of pollution and pollutants.

This air purification goes through several steps. Firstly, the purifier sucks in the air in the room in order to retain the particles. The air is then passed through various filters that retain the different types of pollutants present in the air.

Depending on the performance of your air purifier, it will be able to treat different volumes of air associated with the size of your rooms (bedroom, living room, dining room), offices, common areas, open spaces, etc.

For optimal operation, it is essential to integrate one air purifier per room: we always talk in terms of partitioned areas.

What are the targets of the pre-filter of an air purifier?

The pre-filter captures macro-particles such as coarse dust, animal hair, etc. Placed directly between the front door and the other filters, it is the first filtration system, acting as soon as the air enters the appliance. This filter, which is generally washable, preserves the life of the other filters by filtering macro-particles upstream.

Is the medical-grade HEPA filter effective against viruses?

The HEPA filter of a professional air purifier like EOLIS Air Manager is able to retain more than 99% of particles larger than 0.3 µm. This filter is of medical quality. It is also called an absolute filter.

It is made of a very fine fibre layer. Thanks to its tight weave, it retains dust mites, pollen, mould, fungi, pesticides, bacteria, viruses, fine dust, animal hair and diesel particles.

Is an air purifier effective against coronavirus and Covid-19?

The EOLIS Air Manager air purifier is 99.6% effective against coronavirus. This result was obtained and certified through tests conducted by an independent microbiology laboratory. They were published in November 2020 by NatéoSanté. They were carried out on a strain of human coronavirus (HCoV-229E) close to the SARS-CoV-2 strain responsible for the Covid-19 epidemic.

What is the role of the activated carbon filter?

The activated carbon filter is mainly used to destroy bad smells present in a room. It is a filter containing activated carbon beads that filter and eliminate toxic gases like benzene, hydrogen sulphide, formaldehyde, ammonia vapours, bleach, bad smells, etc. Activated carbon filters, used by NatéoSanté in its air purifiers, also help to eliminate excessive ozone quantities in your air.

How does oxidation/UV-C air filtration work?

The polluting particles are absorbed through an oxidation and reduction reaction between the catalyst and the UV-C radiation. This process converts the VOCs into H2O and CO2. This function can be activated and deactivated on our models.

What is the purpose of the Active Oxygen Generator?

The active oxygen function treats the indoor air deeply. This function, to be activated when you are not present in the room or at your workplace, eliminates incrusted odours (sheets, textiles, carpets) and also treats the space against mites and mould. This feature is available as an option on the EOLIS Air Manager professional indoor air purifier. It can also be activated and deactivated on our various models.

How to choose the right indoor air purifier? 

Each air purifier has its own performances and technical characteristics. Before buying an air purifier, you should compare the filtration levels of the different devices and consider these criteria when purchasing your air purifier. The effectiveness of your product against domestic pollution depends on precisely how you use the device and which one you choose. Asthma, allergies, fine particles, odours, and more—for some, it is used as a preventive measure, for others it simply provides extra comfort by promising healthy and purified air. Here are the criteria you should consider when purchasing your air purifier:

Adapting the air purifier to the room to be treated

Choisir son purificateur d'air selon sa surface à purifier

The surface area treated: Each air purifier treats an area ranging from 25 m² to 120 m². It is necessary to use a device of the appropriate size for the dimensions of the area being treated. For optimal air filtration, the air circulation should be limited to within the area—each enclosed space should have its own device. An undersized device or one used in several rooms will be far less effective.

Choosing the right level of filtration

The filters: Different air purifiers use different filtration systems. At NatéoSanté, we use 4 levels of filtration. Each of the air purifiers’ filters and each option has a specific function that removes a type of pollution. Think about the sort of concerns you have and choose an appropriate device for your situation by checking the effectiveness of each level of filtration (see above).

Pay attention to the noise level of the air purifier

Choisir un purificateur d'air silencieux

Noise level: Hearing comfort is important because your air purifier is with you every day. In order to function properly, it must run continuously and not bother you all day long. NatéoSanté air purifiers also have an extremely quiet night mode that allows you to sleep next to the unit without being disturbed.

Individuals, professionals… homes and offices: who should use an air purifier?

The air purifier is intended for anyone (CEO, Head of Human Resources…) wishing to treat the air quality at their home or place of work. The air purifier can be used for both curative and preventive purposes. It is extremely useful for people suffering from respiratory diseases such as asthma or allergies, but also for people who want to eliminate pollution or bad smells.
