Hepa Air Cleaner Purifier

Indoor air pollution is a major issue in today’s homes. By making houses self-contained, home-builders have

created the ironic situation that the air inside a home is more dangerous than that outside.

HEPA (an acronym for “High Efficiency Particulate Air” or “High Efficiency Particulate Absorbing”) filters were originally designed for the Manhattan Project, in order to filter radioactive particles out of the air. Since then it has been incorporated into other systems that required relatively pure air. HEPA filters are capable of taking out 99.97% of all particles in the air that are .05 microns in size, making them very efficient filters.

When it comes to finding ways to help home-owners defeat indoor pollution, HEPA filters are a very effective way to do it. Throw in all that goes into the modern purifier, and you have a very effective means to deal with dirty air. And it comes with an added benefit to severe allergy sufferers: There is no ozone sent into the local environment.

All diamonds have a flaw. HEPA filters have some limitations. An obvious one is that they are collecting all of the bigger particulates in that air and drawing them to one area. As this includes the bacteria and viruses throughout the home, it is possible that the germs will build up, grow, and infect the home with even greater force. Thus, an ultra-violet light is installed in the unit; the light breaks down the germs, rendering them safe.

Another problem is that odor particulates are too small for the filter itself. Because of this, most HEPA filters are backed by activated charcoal (usually from coconut fibers) that soaks up the odor. This allows the purifier to take care of any stray odors in the room, and contribute to a fresher smelling room.

The last problem area was the fan. The fan is set up to draw in the air so it can be purified. However, it tended to run too loud. This has been changed, so that the fan runs as quietly as a computer fan. It can barely be heard, and quickly fades into the background.

The HEPA air cleaner purifier hasn’t gone beyond its roots of taking most particulates out of the air. As long as the filter is replaced every few months, the HEPA air cleaner purifier will do a fine job in any almost closed-room situation. And, as they are part of most purifiers on the market, they are a welcome addition to any air purifier system!
