The Popularity Of Ionic Air Purifiers
Home air purifiers have done much to improve the quality of the air in both homes and offices alike, effectively combating indoor air pollution. You will find that there are five distinct types of air cleaners, each with differing specialties. These types of purifiers are: HEPA, ionic air cleaners, activated carbon, ozone and UV light.
HEPA air cleaners are the most common type and are well suited for trapping allergens. The designation HEPA, is defined as a filter that is able to contain particles as small as 0.3 microns and will catch at least 99.97% of pollutants as small as that. HEPA air purifier systems are commonly seen in hospital settings. They have filters which must be replaced regularly, normally about twice per year, although some filters can go several years between replacements. HEPA air cleaners are not effective for the removal of cigarette smoke, fumes, gases or odors, and for this reason sometimes a carbon filter is also combined in HEPA air purifiers.
Ionic air cleaners are able to eliminate very small particles from very large spaces. Ionic air purifiers are also commonly called electronic air cleaners and they function by charging the air with a positive electrical charge. Then the charged air is attracted to collection plates within the unit that have a negative charge, creating a completely silent method of circulation without the use of fans.
Ionic air cleaners are also well suited to remove particulates in the air, but they use no filters. Instead, the charged particles adhere to the collection blades, which can then be easily wiped down to clean them of the captured contaminates.
