Get the Healthful Air from HEPA Air Purifiers

Air purifiers are designed to filter out the harmful particles and allergens from the air. Among the various types and sizes of air purifiers, the most popular is the HEPA air purifier. HEPA means “High Efficiency Particulate Air Filter”. This type of air filter is often used in air cleaners, air purifiers, and high quality vacuum cleaners.

A HEPA filter can remove the airborne particles down to 0.3 microns in size and have an efficient rating of 99.97%. HEPA filters are replaced regularly to ensure optimal performances of air purifier. It'll also extend the life of your air purifiers.

Air cleaners trap airborne particle by passing dirty air through a HEPA filter and allowing a clean air to return to the indoor environment. As the air in the room is exchanged several times, better air quality is achieved. It has the higher air exchange rate per hour. The Ideal number of air exchange per hours is between 4 to 6.


These air cleaners can use medical grade ultraviolet light system for purification of the air. UV light system kills the bacteria, virus, molds and dangerous pollutants. This type of air purifier is capable of protecting your indoor environment from micro-organisms as well as dust, pollens, dust mites, out gassing chemicals and odors.
