 Tips on Air Cleaners
- Filter effectiveness or efficiency refers to the percentage of particles removed from the air that passes through the filter media. A high efficiency particulate air filter, or HEPA filter, is capable of removing particles as small as 0.3 microns at a minimum efficiency of 99.97 percent.
- Air Circulation Capacity or ACC is measured in air changes per hour (ACH). Each ACH represents how many times per hour the air in a specific room size should be circulated through the air cleaner.
- Air cleaners are not a cure for allergies.
- Air cleaners are effective only when air is circulated through them.
- Set your thermostat to "Fan," "On" or "Manual"
position for continuous air cleaning when not heating or cooling. (This
approach uses more electricity and reduces the life of the blower.)
