Filter King 21.25x21.25x1 size air filters are used by accompanying air systems to keep pumped in air clean. The filters consist of a tight mesh weaving designed to capture and absorb a range of irritants entering your home via airflow. Air filters work constantly as the air continues to come in, cycling fresh air throughout your home. The process raises your home’s indoor air quality and keeps the air coming in free of harmful particles. Your air filters become dirtier over time, and will eventually need replacement before they start causing problems.
When the air filters in your home become dirty, they end up causing several problems for their systems and your home. The dirty filters will block off airflow, which means that the air inside your home will be unable to cycle out leading to dryness and stagnation. Your air systems also face issues as they attempt to push airflow past the blockages and into your home. The efforts will lead to mechanical damage for your systems and a rise in energy billing over time.
The air systems in your home work best when the air they bring in is allowed through new air filters without any problems.
