Information on Air Cleaners
Below are the main types of air cleaners available.
Activated Carbon Air Cleaners - charcoal that has been treated with oxygen to open millions of "pores" which trap and absorb gases and odors. This same material is used in military gas masks to keep soldiers safe from poisonous gases.
Ionizing Air Cleaners - ionizing air cleaners trap airborne particles as they pass over electrically charged blades. The blades can be cleaned and replaced so there is no need to ever replace filters. Ionic air cleaners have come under great criticism for creating ozone levels which can cause shortness of breath and wheezing. A test conducted by Consumer Report's implicated 5 or 6 tested ionizing air cleaners.

Hepa Filter Air Cleaners - "high efficiency particulate arrester" or hepa is a type of air filter that is capable of filtering out air pollutants as small as 0.3 microns. By the nature of being a filter it is recommended that you replace the hepa filter every 1-3 months depending upon the amount of particles in the home. Hepa filters typically cost from $10-40 depending upon the model.
