Dirty Air FilterHVAC Air filters become dirty as they clean your air. Trapping dirt, debris, hair, chemicals, mold spores, bacteria and other contaminants. It may surprise you how quickly this can happen.

As more and more foreign materials become trapped in the fibers of the filter, less and less air flow occurs. This can negatively impact the operation of your HVAC equipment and make it work harder using more energy. Additionally, your system becomes less and less able to filter out those contaminants leaving them in the air you are breathing.

Pets heavily contribute to contaminants in the air and changing your filter more frequently is important if you have pets.
