20.75x21.75x1 Air Filter

Filter King 20.75x21.75x1 size air filters are necessary parts of your air systems, used to clean up passing airflow. The air systems throughout your home are constantly bringing in fresh airflow, but they have no way to differentiate the clean air from the dirty. Air filters are the tool used to clean out fresh air so that it does not bring in any allergens or pollutants. Your home’s indoor air quality is reliant on how well incoming airflow is filtered. Air filters keep the air in your home comfortable and safe to breathe, but they will grow dirtier over time.

The air filters in your home will cause problems for their system when they become dirty, and eventually cause problems for your whole home. Fresh air flow is necessary for your home in order to keep the air inside from stagnating or drying out over time. Your air systems will also become strained as they struggle to push airflow past the blockage. The continuous strain will eventually cause mechanical damage, a costly expense on top of the additional energy billing. New air filters will help prevent these issues from developing over time and keep air coming in smoothly.

The filters in your home need regular replacement in order to make sure that the air coming in is kept clean. We offer new 20.75x21.75x1 size air filters ready for installation upon arrival via our delivery service. Orders of two or more filters are shipped for free, while our subscription option has new air filters delivered as often as monthly. Filter King offers filters that have a MERV (Minimum Efficiency Reporting Value) rating of eight, meaning they are capable of blocking out particles like:

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

20.75x21.75x1 Furnace Filters

The furnace filters in your air systems keep heated airflow clean before distribution throughout a system. The filters grow dirtier over time, which is a problem for your home when the temperatures begin to build. Heated airflow needs release or the resulting heat fluctuations will only grow worse over time. Purchase new air filters today to keep airflow coming in smooth and clean.
