HEPA Air Purifier

An air purifier is an appliance used for cleaning air indoors and they are used in homes, industrial workplaces, commercial buildings etc. The application of air purifiers is usually in places which tend to have unhealthy air due to pets, pollutants, molds, smoke or industrial work, hazardous materials etc. Air purifiers are also popular in homes of allergic people and people with asthma who wish to keep the air healthy in their homes and offices. They are also popular due to the fact that the air inside homes is fewer healthy than the air outside.

A HEPA air purifier is an important component to maintaining an allergen free and healthy home. Short form for HEPA is High Efficiency Particulate Air.  HEPA filters are very popular for air purifiers before being designated as HEPA, air purifiers should meet very stringent requirements as laid down by the Department of Energy. HEPA filters must remove at least 99.97 % of air borne particles of 0.3-micron size at 85 liters per minute rate. However HEPA filters are very expensive and replacing the filter in the purifier may cost the purifier itself. Further HEPA filters can’t remove gases or odors from the air. For removing gases absorbent type of air purifiers are appropriate.

HEPA Air purifiers are generally having a built in fan, which serves to circulate the air in a specific room of the home. HEPA air purifier includes a filtration system, which captures and destroys the various pollutants in the air that is passed through the filter. Specifically, the room air is drawn into the air purifier and is trapped through the use of air filters. The particles, drawn from the air, are electrically treated which results in these particles obtaining an optimistic charge. Following this treatment, plates within the air purifiers are electrically charged which results in these plates becoming the opposite in polarity. This results in a magnetic effect that captures the particles and holds them fast.

In addition some HEPA air purifier have a charcoal system, which filters the air and captures odors lingering in the room. These odors could be foods, cigar or cigarette smoke, etc. The final process with some air purifier is the return of air to the room once it has been refreshed. This refreshed air is accomplished through an ionization procedure of the air. It is anticipated by some authorities that the air within an individual’s home is far more polluted than the air breathed outside the home. This is a remarkable assertion given the fact that the air, outside the home, is polluted with car and industry pollutants.
