20x21.5x1 Air Filter

Filter King 20x21.5x1 size air filters protect your home by cleaning out incoming airflow free of harmful irritants. The airflow in your home is constantly coming through your systems, but they have no way to tell the clean air from the dirty. Air filters are made of a tight mesh weaving that allows airflow to pass through naturally, while particles are captured and absorbed. The process cleanses the airflow, but the filters become dirtier over time and cause indoor air quality to dip. Eventually, they will require replacement in order to keep the air coming in without any issues.

Your air filters will become covered in particles over time as they continue to capture and absorb them. The dirty air filters eventually become so covered in particles that they are cannot effectively allow airflow to pass through. Without fresh airflow, the air inside your home is subjected to drying out and stagnation. Your air systems also become more strained as they try to push airflow through the blockage. The resulting effort caused mechanical problems and leads to a rise in energy billing.

Your home air filters need regular maintenance in order to keep airflow coming in smooth and clean. Filter King offers new, fresh 20x21.5x1 size air filters that are installable upon their arrival. We also have a delivery service, along with a subscription option, where orders of two or more filters are shipped for free. Filter King model filters have a MERV (Minimum Efficiency Reporting Value) rating of eight, and block out particles like:

  • Pollen
  • Dust
  • Mold
  • Dust Mites
  • Bacteria
  • Pet Dander
  • Smoke
  • Viruses

20x21.5x1 Furnace Filters

Your furnace filters work in the system to clean heated airflow before distribution into your home. Your filters will continue working until they become dirty, and at this point they become a problem that needs addressing. Heated airflow needs release, or the furnace temperature begins to rise to a high degree. If the temperatures are too high, then the furnace may become damaged and require some expensive repairs. Your home will also see temperature fluctuations when the heated airflow is not able to warms its rooms. Order new filters today and keep airflow coming in through your systems without issue.
