The principle behind an air filter is quite simple. The filters are made of a mesh of strands of fiberglass that prevent larger particles in the air from passing through them. The strands attract and stop dust, pollen, pet dander, dust mites, construction debris, and many other harmful particles. If the filters become too congested, they can be changed out for new ones. (It’s very important that filters receive routine maintenance to make sure they are clean enough to do their job.)

Although your air conditioning and forced–air heating system comes with an air filter, this filter is not designed to clean the air. Its purpose is to prevent debris from entering the AC and heater cabinet. You need to have a dedicated air filter installed for proper indoor air quality treatment.

There are many kinds of filters with different levels of effectiveness available. A rating system called MERV (minimum efficiency reporting value) measures how well a filter traps particles. But the highest MERV rating possible doesn’t necessarily mean that a filter is the right one for your home. In fact, it will probably cause far more problems than it will solve because it will choke off airflow through the ventilation system and place enormous strain on your AC and heater.

It takes an IAQ expert to determine the best filter or set of filters to provide you with the clean indoor air you want for your home.
