Why Buy Air Filters From Filter King?


In comparison to fiberglass filters, 22x37x1 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 22x37x1 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.

22x37x1 Air Filter

Filter King 22x37x1 size air filters are important tools used to keep the air in your home clean and comfortable to breathe. The air systems throughout your home have no real way to separate the good air from the bad. Filters clean out the incoming airflow free of irritants by trapping the particles in their tight mesh weaving. As the clean air comes in, the air quality of your home rises as it becomes more comfortable and safe. The filters, in turn, become dirtier over time as they continue to capture particles.

Dirty air filters are the result of too many particles being captured over time, leading a blockage in the system. Airflow is unable to pass through the dirty filters which leads to problems of dryness and stagnation throughout your home. Your home air systems also face issues as they become strained trying to push airflow past the dirty air filters. The systems may suffer mechanical damage over time as they continue to become overworked. Your home will also see temperature fluctuations as the any cooling airflow is stopped. The strain also causes an increase in electricity usage, which leads to higher energy billing over time.

You home will have an easier time having breathable air when the filters in your systems are replaced regularly.
