Air Purifier
An air purifier is a device designed to filter the ambient air in a room to eliminate all pollutants. Used by both individuals and professionals, these devices improve air quality by purifying indoor or industrial air.
There are different types of air purifiers:
- Filtration purifiers: Air is drawn in by a fan and passes through multiple filters (pre-filter, HEPA filter, activated carbon filter, nanoparticle filter) to limit the spread of harmful residues.
- Ionization purifiers: They combine filtration and ionization of the air.
- Photocatalytic purifiers: They destroy pollutants using strong light radiation on a catalyst.
- Combustion purifiers: They burn pollutants.
- Plasma purifiers: They excite oxygen molecules to oxidize and destroy pollutants.
- Washers: They combine humidification and air filtration.
Air purifiers are equipped with various filters:
- Pre-filters: Capture large dust particles and pet hair.
- HEPA filters: Filter microparticles larger than 0.3 μm, such as dust mites, bacteria, and pollen.
- Activated carbon filters: Eliminate odors and VOCs.
- Nanoparticle filters: Filter microparticles larger than 0.1 μm.
- Washable or electric filters: Have electrostatic properties and are reusable.
These devices aim to prevent respiratory issues and improve air quality.
