Filter King 21.5x23x1 size air filters have the crucial job of keeping incoming airflow clean as it enters your home. The air filters you purchase consist of a tight mesh weaving that allows airflow through but prevents irritants from dirtying up your systems. The cleaned-out air will then cycle into your home and provide it with a fresh, clean smell. The indoor air quality of your home raises and remains high as your filters continue to clean out incoming airflow over time. The process will continue until your air filter becomes too dirty to effectively allow airflow to pass through.
Your air systems grow dirtier over time as they continue to capture particles in their tight mesh weaving. Eventually, the air filters become so dirty that airflow will have an issue going through them and into your home. When your home lacks fresh airflow, then that means that the air inside will begin to grow dry and stale over time. Your air systems will also become strained as they are forced to push airflow through the blockage. The resulting problems include mechanical damage and increased energy billing over time.

Your air filters are capable of fitting in several air systems situated around your home, including your furnace. The furnace needs air filters in order to keep the incoming heated airflow clean of any irritants. Over time, the filters become dirtier and end up blocking heated airflow from entering your home. If the air is not allowed through, then that may cause a buildup in heat that could seriously damage the system. Your home will experience temperature fluctuations since they are not being heated.
