A clogged or dirty air filter restricts airflow, which causes your heating and cooling system to work harder and use more energy to warm or cold your home or/and office. Just like you replace your car’s air filter, consider replacing your HVAC air filter to protect your system from expensive repairs. In addition to driving up your energy bill, your indoor air quality also gets polluted and exposure to this polluted air causes many severe respiratory health problems. So what’s the big deal? Does your HVAC air filter really matter?

Important Note: When looking to replace your air filter, make sure you compare its nominal size and actual size. The nominal size that is printed on the side of your air filter is rounded up to the nearest whole inch. For example, if the nominal size of the filter is 18x20x2, the actual size will be 17.5×19.5×1.75
