Air filters in your heating/cooling unit don’t last forever. When your HVAC system works, air filter filters a large number of particles such as dust, pollen, bacteria, and mold from your air. So, air filters get clogged-up after some time depending upon the furnace usage. A dirty furnace kills your unit’s energy efficiency. If you ignore changing dirty air filters, it can send bacteria, smoke, gases, and odors all over your house that can cause asthma or other respiratory illness to your family.

A rounded up number is used to label filter packages, referred to as the nominal size. So, measure your filter dimensions accordingly before ordering!
