Why Buy Air Filters From Filter King?


In comparison to fiberglass filters, 20x22.25x1 pleated air filters are at least 20 times more effective. All Filter King air filters are made in the US.


Filters frames are made out of heat resistant paperboard with horizontal grid supports. Able to withstand temperatures of up to 200° F and resistant to moisture, the paperboard frames do not support microbial growth and outperforms traditional cardboard frames.


Chemical free, electrostatically charged synthetic polyester media is pleated, maximizing the surface area, to capture a high number of airborne particles as small as 0.3 microns with low air flow resistance. To increase durability, the media is supported with a corrosion resistant steel wire.

How Often to Change Your 20x22.25x1 Air Filter?

Filter King AC & furnace filters aren’t the typical fiberglass filters that need to be replaced every 30 days. Our filters can typically be used for 3 to 5 months before requiring to be changed. Naturally, a variety of things influence filter lifespan.

Some of the factors that influence your filter’s life include outdoor air quality, whether pets are in the home, and how well your HVAC system is maintained.

Your air filter becomes clogged over time by trapped particles, preventing airflow. The efficiency of the HVAC filter declines. Your system must work harder to heat and cool your home. The extra strain on the HVAC system causes higher energy bills. Regular home air filter replacements can prevent expensive system repairs or replacements down the road.

You should change your filter more frequently if you notice:

  • Household dust build-up
  • The air isn’t cooling as is used to
  • There’s more dust near the air vents
  • A dirty filter surface
  • Higher energy bills
  • Burning smells near your HVAC system.

20x22.25x1 Air Filter

Filter King 20x22.25x1 size air filters go into your home air systems with the express purpose of cleaning up incoming airflow. The air filters in your home are constantly working since your air filters continue to bring in fresh airflow. The resulting cleaned airflow raises indoor air quality and helps make it safer to breathe in your home. The filters continue to capture and absorb particles in their tight mesh weaving until they become completely covered in them. The dirty filters are less effective over time and need replacement before they start causing problems for your home.

When the air filters in your home systems become dirty, it becomes important to replace them before they start causing problems for your home. Dirty air filters are so covered in particles that they become unable to process airflow. The resulting problems lead to the air inside your home drying out and stagnating. Air systems are also forced to use additional energy in an attempt to push airflow past the blockage. The rise in energy usage may cause mechanical damage over time and an increase in energy billing.

Your home air filters will require replacement over time, new filters will allow airflow to pass through smooth and clean.
