Clean Air Purifiers

Clean air purifiers work by cleaning the circulating air. There are several purifying technologies, including UV, electrostatical, and ozone-based air purification.

Which technology you should choose depends on your situation. For example, the American Asthma and Allergy Foundation of America (AAFA) has recommendations as to which type of purifier to choose.

Overall, the AAFA recommends that the best way to reduce allergens in the home is to eliminate the source of the allergens from the home.

Clean Air Purifiers - AAFA Recommendations

As for different air cleaner types, the foundation has determined through existing research that the efficiency of these cleaners is limited.

According to the foundation, there are many more allergens in carpets and furnishings than in the air, reducing cleaners effectiveness.

However, air conditioners can help reduce humidity which helps decrease dust mite and mold growth.

If you decide to use air cleaners, the foundation recommends air HEPA filter powered ones with high particle removal rates.

As for the controversial ozone generating cleaners, the foundation points out that ozone can be dangerous for persons with lung disease such as asthma and therefore ozone generators are not recommended by them.
