Choosing an air purifier is made easier when you know what kind of pollution you would like to eliminate from the air. You’ll need an air purifier with a high-efficiency particulate air (HEPA) filter, that can filter pollutants as fine as 0.1 microns, to try and eliminate them from the air.

Dust: Mold spores are microscopic organisms that prefer hot, moist settings to survive. It can be found in bedding, carpets, home furniture, and cuddly toys and are a typical source of asthmatic and seasonal allergies.

Pollen: To fertilize nearby plants of the same kind, trees, grass, and weeds release minute pollen grains into the air. Oedema, a drippy nose, and eye irritation are typical allergy symptoms that can be brought on by pollen.

Smoke: Cigars, wood-burning stoves, fireplaces, and lanterns all produce smoke particles. Smoke can aggravate symptoms of asthma by irritating the eyes, nose, and throat.

Viruses:  Viruses are tiny, infectious particles that can cause respiratory illnesses such as the flu.

Fungi:   Fungi are a type of microorganism that can cause infections in humans.

Bacteria:  Bacteria are single-celled microorganisms that can cause infections in humans.

Odors:  Odours are airborne molecules that can cause unpleasant smells.

Every three to six months or as instructed by the manufacturers, you must replace the filter. The effectiveness of the air purifier will be diminished by a blocked filter.
