Our medical grade air purifiers.

Air Purifiers, operations and maintenance

We spend 90% of our time indoors, at home or in the office, and we are therefore very exposed to fine particles and indoor pollutants that are harmful to our health in the long term.

When we are at rest, it only takes one minute for the 5 liters of blood contained in the human body to pass through the 75 m² of our lungs. This is the reason why indoor air quality not only has an impact on our respiratory capacities but also on our entire body, including the cardiovascular system.

The importance and popularity of indoor air purifiers is on the rise and these devices address concerns regarding air quality and the presence of viruses and bacteria. Find out how these devices work, their efficiency and how to maintain them.

How does the air purifier work ?

An air purifier is a device that filters the air and rids it of biological and chemical pollutants, foreign particles and the indoor pollution it contains, in order to improve and clean the quality of indoor air.

Air purifiers withour filter

• Photocatalysis : Its principle is the decomposition of biological and chemical pollutants into water vapor and carbon dioxide. VOCs (Volatile Organic Compounds) as well as fine particles (PM) are treated using the catalyst (titanium dioxide) and under the action of a light ray (UV lamp, in the case of an air purifier). air). This involves ensuring their design and production so that they do not emit by-products such as ozone (O3).
• The air ionizer: A device of this type produces/emits negative ions into a room to trap the positive ions. With the ionizer, negative ions are released into the air and mixed with pollutants, dust, fine particles and VOCs, which become heavier and fall to the ground. They can be cleaned with a vacuum cleaner (with or without HEPA filters).
• Cold plasma : Viruses are sensitive to cold plasma which is a created product and does not come from a natural environment. It is the fourth state of matter which comes after solid, liquid and gas. The cold plasma reaches the atoms and viruses which are on the surface of objects and are neutralized by the principle of oxidation. The constraint of purification via cold plasma is that it generates pollutants such as ozone and nitrogen oxide, which are harmful to health if there is too much exposure.

The recommendations of health agencies are to use air purifiers with mechanical filtration, equipped with at least HEPA 13 filters.

Il est bien entendu incontournable que votre purificateur n'émette pas de sous-produits, ne produise pas d'ozone ou bien de composés organiques volatils (COV).

Les purificateurs d'air à filtres de qualité médicale

Un filtre HEPA est considéré comme un filtre de qualité médicale à partir du niveau HEPA H13. HEPA signifie High Efficiency Particulate AIR, traduit en France par filtres absolus ou THE (Très Haute Efficacité)

It is of course essential that your purifier does not emit by-products, does not produce ozone or volatile organic compounds (VOC).

Activated carbon technology allows "molecular" filtration and associated with HEPA 13 or HEPA 14 filters which produce "particulate" filtration, the whole allows complete filtration of very high efficiency. This is the solution chosen by health agencies such as ANSES or the High Council for Public Health, which is the most reliable, simple and economical very high efficiency filtration solution (THE).

The indoor air purifier with filter helps fight asthma, viruses, bacteria, pollution, allergens, VOCs (Volatile Organic Compounds) and certain odors (tobacco, aerosols including formaldehyde, etc.).

AIR ET SANTÉ air purifiers come in several ranges adapted to individual needs and to the surface area (from 20 to 800 m2) and volume (from 100 to 2000 m3/h) of the interior space to be purified.

1. Air is drawn into the air purifier and passes through an antimicrobial-treated pre-filter. This eliminates all large dust to avoid too rapid clogging of the filtration system, extending the life of the HEPA filter. 
2. Air passes through the HEPA filter. The H13 filter retains 99.95% of ultra-fine particles down to a size of 0.1 µm and the H14 99.995%
3. Then the air passes through the activated carbon filter which adsorbs the VOCs (Volatile Organic Compounds) present in the air. It also has an action on many odors such as tobacco and humidity. 
4. The air passes through the catalyst, a filter treated with lanthanum which has the property of degrading pollutants into infinitesimal quantities of water vapor and carbon dioxide.
5. The air passes to the level of photocatalysis, activated with UV lamps. The last fine particles and volatile organic compounds are mineralized and transformed into tiny quantities of carbon dioxide and water vapor.
6.  The purifiers have negative ion emitters (ionizers) that aggregate with pollutants, weigh down their masses and cause them to fall to the ground.

Finally, the treated and purified air is returned to the room, cleaned of its pollutants.

Some of our devices have specific features: the AS300 Premium also offers H14 filter packs which eliminate up to 99.995% of fine particles of 0.1 micrometers and the AS200 Medium is our only air purifier which includes the humidifier option.

All our purifiers have pre-filters for thick particles, HEPA filters, activated carbon filters and photocatalysis grid with UV lamp.

And, the efficiency of all our purifiers can be further improved by using HEPA 14 filter blocks which also contain an even greater volume of high-density activated carbon.

How to maintain an air purifier ?

To extend the life of the filters and ensure proper functioning of the air purifier, it is recommended to vacuum the pre-filter on average every two weeks and to frequently clean the interior and grills of the device.

Depending on the duration of use of the device, the pollutants treated and the environment in which it is located, the filters will need to be replaced every 6 to 12 months.

Each model of device has an indicator light that will light up to indicate when the filters need to be replaced.

To guarantee the effectiveness of the purifier it is very important to replace the filters regularly.

How replacing the filters ?

Replacing the filters of Air et Santé air purifiers is similar on all devices and very simple, it only takes 3 minutes.

1° Step: Turn off the Air et Santé air purifier and unplug it from the electrical outlet.

2° Step: Open the cover on the front of the air purifier by lifting it and pulling it slightly towards you.

3° Step: If there are filter retaining hooks, turn them to release the used filter.

4° Step: Remove the filters or filter block while wearing gloves and mask if necessary; be careful not to shake them during this step to prevent dust and other fine particles and VOCs from falling.

5° Step: Insert the new filter block respecting the planned arrangement.

6° Step: If necessary, fold down the hooks to block the filters.

7° Step: Close the air purifier, reconnect it and put it back into service.

So simply insert the block with the white HEPA Filter facing you in the same direction as you removed it.

How long does it take to purify the air in a room?

The time required varies, certain factors must be taken into account:

•  Adjusting the filtration speed of the purifier which regulates the adsorption of pollutants and the rejection of purified air.
• The volume of air and the surface to be treated. The more space there is, the more time the air purifier requires to analyze and retain the fine particles and pollutants present in a room.
• Environmental factors that can move pollutants into a room, for example if a window is open, after the use of household products or infiltration of outdoor pollution indoors.
• The attendance of the space to be purified, the number of people present as well as their behaviors and lifestyles.
• The size of fine particles, if they are less than 0.1 micrometers.

The ANSES recommendations are to obtain an air renewal rate of 2 times per hour and the HCSP recommends 5 times per hour.
