Furnace and AC filters should be changed about every 90 days. Making sure your system is equipped with capable air filtration is the first step, but filters that are too dirty or clogged will stop serving their purpose.

Heating maintenance and AC maintenance are essential for removing all the airborne contaminants that can affect the air you breathe at home. Make sure to follow your IAQ specialist’s advice on how to best manage and maintain your air filtration system.
