Air Purifiers: Air Cleaners

Air cleaners are becoming more and more popular in households these days. It seems like every home has at least one air filtering system in its bedrooms. Theres good reason for this. Indoor air has been proven to be more polluted than the air outside our homes.

Its true, poor air circulation causes the air inside our homes to be a host of trapped airborne particles and dust. Normally, wind gusts and breezes would clean the air out, but with the windows closed, or little or no air flow, this simply isnt possible. To make matters worse, we unfortunately spend the vast majority of our time indoors.

Air cleaners purport to help purify the air in our homes, and most do this in a couple of standard ways. Many air cleaners will have a sponge-like pre-filter. This is the first line of defense against airborne pollutants. Then they will have a more sophisticated main filter. HEPA filters are perhaps the best, and the most well-known filters on the market.

Air Cleaners Use Ionization
Some of the very best air cleaners dont stop at two filters, but add a third air cleaning element: ionization. Ionization is the releasing of positively charged particles into the air. These charged particles attract and clump together with negatively charged dust particles, causing them to fall and be sucked in by the air cleaner.
