13x21.5x1 Air Filter

Filter King 13x21.5x1 size air filters are quality tools necessary for an air system in order to clean up incoming airflow. The air surrounding your home may have all kinds of pollutants or allergens in it, all of which are capable coming into your home via airflow. Your air systems need to filter the incoming air in order to ensure that it does not cause any complications with your home’s indoor air quality. The irritants become captured by your air filters tight mesh weaving, which only becomes dirtier over time.

The air filters in your home will continue to filter out incoming airflow until they reach the point where their mesh weaving becomes full. The resulting blockage leads to problems with air cycling throughout the home. When the air already inside your home is unable to cycle out, that causes dryness and stagnation. Your air systems will try to push airflow past the problem, which generally only leads to increased energy billing and system strain.

You will need to periodically change out your old filters in order to keep the airflow coming through without problems.
