16.5x21x1 Air Filter

Filter King 16.5x21x1 size air filters are common tools used by your air systems to keep incoming airflow clean and clear of harmful airborne particles. Your home’s indoor air quality depends on your its air systems ability to clean out incoming airflow. When the air quality of your home is lowered, that causes the air in your home to become uncomfortable or unsafe to breathe in. Air filters are necessary parts of an air system, and help keep incoming airflow clean, but become dirtier over time.

Your air filters become dirtier the longer they remain installed in an air system, they are in constant use as air keeps pumping inside. The dirty air filters in a system are unable to properly allow the passage of airflow, which leads to problems developing all over your household. Lack of airflow means the air does not cycle, which causes the air inside your home to dry out and stagnate. The lack of airflow also causes your air systems to use more energy, which may lead to increased billing and possible mechanical failure.
