Air Filters are the lungs of your AC system. When dirt, dust, dander and other harmful particles clog the surfaces of your system filters, air flow reduces which leads to a decline in the efficiency of your system as well as polluting your indoor air. It is always advisable to change the air filters at least every 90 days.
