air filterAir Filters and Filter Media Are Key to Your System


Air filters and filter media are surely the least expensive and most accessible component to an air conditioning and heating unit. It is a key factor in the system. Air filters regulate the amount of air that enters your system and the quality of the air that comes out. They are designed to capture harmful elements like pollen, dust, bacteria, mold, and viruses.

When a filter is dirty, it should be replaced with a new one. Having new filter media on hand and keeping your filters clean will not only help to keep your air clear of harmful contaminants, it will keep your system clean, as well. If your filter is dirty, your system runs harder and is more susceptible to breaking down.
