Types of Home Air Purifier

A good-quality air purifier will do a great job of cleaning the air in your home. The most helpful purifiers will do this automatically when they sense a dip in air quality. But there are plenty of home air purifiers that are not powerful enough to clean air quickly enough. As it’s important to buy an air purifier that does a good job of cleaning air quickly, it’s worth doing some research before heading to buy a new machine. Following is the type of air filters available in the market for home buyers.

HEPA Air Purifiers or HEPA Filters

High Efficiency Particulate Air or HEPA air purifier or HEPA fIlters  remove at least 99.97 percent of 0.3-micrometer particles and are usually more effective at removing larger particles. They filter all the air going into a clean room, and it must be arranged so that no air bypasses the HEPA filter. In an industry environment, a HEPA filter may follow an easily cleaned conventional filter (prefilter) that removes coarser impurities so that the HEPA filter needs cleaning or replacing less frequently. HEPA filters do not generate ozone or harmful byproducts in course of operation. HVAC (heating, ventilating and air conditioning) filters at MERV 14 or above are rated to remove airborne particles of 0.3 micrometers to 1.0 micrometers. The capture rate of MERV filters is lower than that of HEPA filters.

Activated Carbon Filter

is a porous material that can absorb volatile chemicals on a molecular basis but does not remove larger particles. Activated carbon is merely a process of changing contaminants from a gaseous phase to a solid phase; it is normally used in conjunction with other filter technology, especially with HEPA.

Air Ionizer or Ionizer Purifiers

Air Ionizers use charged electrical surfaces or needles to generate electrically charged air or gas ions. These ions attach to airborne particles that are then electrostatically attracted to a charged collector plate. This mechanism produces trace amount of ozone and other oxidant as byproduct. Most ionizers produce less than 0.05 ppm of ozone – an industrial safety standard.

Our Experts compared 20+ models of 12 brands of home air purifiers on the basis of air purifier price, air-delivery rate, power consumption, warranty along with other important parameters to educate you to know the best air purifier or air filter for home buyers.
