You may have heard about the problems of low indoor air quality in many homes. These aren’t alarmist warnings: the EPA has determined that poor IAQ in buildings is a significant health hazard across the country. In fact, the air inside a building—and this includes your cozy, happy home—can be as much as three to four times worse than the air outside.
One of the basic solutions to poor IAQ for a home is to remove harmful particles moving through the ventilation system with a set of air filters. It takes special filters dedicated to air quality improvements for this job. But this raises a concern that the filters may end up making the air conditioner’s job harder (and eventually the heater’s job). Is there any truth to this?
