Air filters are one of the most basic ways in which you may improve indoor air quality, and also one of the most effective. Mechanical air filters are installed in your heating and air system. Your heating and air conditioning system has a factory installed air filter that must be changed regularly, but the purpose of this filter is not to improve indoor air quality, but to protect the operation of your heating and air system.

This filter has a low MERV, which stands for minimum efficiency reporting value. Usually it is between 1 and 4. The higher the MERV, the more efficiently an air filter is able to filter air as it passes through the system. Air filters can have a MERV of up to 20, though when the MERV reaches a certain point the air filter can create so much airflow resistance that it becomes inappropriate for most residential heating and cooling systems.
