What is an Air Purifier?

Air purifiers are the air filtration tools that capture the harmful airborne particles in their advance filtration system. Therefore, purifying the polluted air and recirculating the filtered air inside the room. Most air purifier are embedded with HEPA (High Efficiency Particulate Absorption) filters to trap particles as small as 0.3 microns.

 HEPA air purifiers perform exceptionally well against pollens and allergens. These purifiers when used in combination with activated carbon filters are capable of removing odors and volatile organic compounds as well.

Do Air Purifiers really work?

Yes, Air purifiers fulfil their purpose in an effective manner. Almost all types of air purifying gadgets have the ability to capture animal hair strands, large debris particles, bacteria and fungi. But the efficiency of each air purifier and pollutant capturing capacity varies with type of filtration system used in it. HEPA air purifiers and Activated Carbon air purifiers are the best among their industrial counterparts.

 The former have outstanding ability to capture particles ranging up to 0.3 microns in size and possess the efficiency of 99.97% while the latter are known for the removal of volatile organic compounds and odors from the atmosphere. Ultraviolet air purifiers are also good in capturing certain air pollutants but are not as efficient as their above mentioned counterparts.

Other types of air purifiers include ionic and ozone air purifiers. After regular use these appliances have been characterized with more harm than benefit. Instead of removing air pollutants, ionic air purifiers only stick them to solid surfaces while ozone air purifiers although eliminate the air pollutants, but create ozone that further creates pollution in the troposphere.
