Poor air quality in the home can have a direct impact on health. By purifying and removing suspended particles, an air purifier (or air freshener) improves the quality of the air in homes or business premises. Utility, operation, maintenance, options and flow, all our tips for choosing your air purifier.

What is an air purifier for?

It is now proven that indoor air can be more polluted than outside air. This is due, among other things, to the lack of daily aeration and the confinement of the rooms in the house.

The presence of animals, cigarette smoke or exhaust fumes are additional sources of pollution, as are Volatile Organic Compounds contained in murals or furniture compositions.

Domestic appliance, an air purifier allows the removal of particles suspended in the air. It filters the air by various processes according to the models, in order to restore a pure and healthy air. By using an air purifier, it is possible to reduce domestic pollution and greatly improve the quality of indoor air.

An air purifier eliminates several types of indoor pollutants:

Biological pollutants:

• Suspended particles such as hair, hair, pollen and other allergens.
• Viruses, bacteria and molds.

Chemical pollutants:

• Chemical detergents and solvents.
• Volatile organic compounds (VOCs)
• Tobacco smoke, exhaust fumes.
• Substances emitted by building and renovation materials.

Physical pollutants:

• Dust.
• Natural or synthetic fibers.

Other purification systems

The filtration by combustion resides in the action of heating the ambient air. The air purifier burns spores, fungi, pollen or other bacteria in suspension thanks to a resistance whose temperature reaches 200 degrees. The hot air is immediately cooled before exiting the purifier.

The plasma filtration is intended for industrial use because it loads the air into ozone and other free radicals. In this type of filtration, the oxygen is excited to generate an oxidative destruction of the pollutants. This is then released into the room to clean the air. Purification is therefore outside the purifier and not inside.

The filtration by photocatalysis comprising passing ambient air into the nanotubes of titanium dioxide. Titanium dioxide creates, thanks to ultraviolet rays, an oxidation of pollutants. This action turns them into water vapor and carbon dioxide.

Choose your air purifier according to the volume of air to purify

Depending on the air purifier model, the optimal area ranges from a few m² to more than 100 m². There are therefore devices suitable for small areas as large premises.

When in the purification phase, the purifying ventilator sucks in and exhales air. From its flow (m3 / h) depends on the ability of a purifier to renew the air in a room several times per hour is guarantee of efficiency. An appliance with a flow rate of 500 m3 / h, will treat 6 times per hour the air of a room of 30 m2 This criterion of choice varies according to the needs and the size of your room.
