Air Purifier: Costs, concerns and clean air puzzle
A home air purifier is a device that removes contaminants (including PM 2.5 particles) from the air in a room. This it does by sucking in the air present in the room and running it through multiple layers of filters to capture the impurities and particulate matter. These devices are commonly marketed as being beneficial to allergy sufferers and asthmatics, and also effective at reducing or eliminating secondhand tobacco smoke. Air purifiers are becoming increasingly capable of capturing a greater number of bacterial, virus and DNA-damaging particulates. High-efficiency particulate air or HEPA air purifier removes particles by capturing them on filter materials and can clear the air of dust, pollen, pet dander, smoke, etc. The commercially graded air purifiers are manufactured as either small standalone units or larger units that can be affixed to an air-handler unit.
