Best Air Purifiers for Asthma
Asthma can be triggered by a wide range of air contaminants such as mould spores, chemical fumes, odours, reactive gasses and pollen. Similar to allergy sufferers, the primary filtration technology to consider is a "True HEPA" or "Medical Grade HEPA" filter. Complementary technologies such as Activated Carbon should also be considered as an additional filtration stage to remove odours, chemicals and other volatile organic compounds. Many air purifiers have additional technologies within their filtration process such as a UV-C light or PlasmaWave which target germs such as bacteria and viruses. Some technologies such as ozone generators and older types of ionizers may cause discomfort to asthma sufferers so should be avoided.
