Why Buy Air Filters From Filter King?


In comparison to fiberglass filters, 11.25x23.25x1 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 11.25x23.25x1 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.

11.25x23.25x1 Air Filter

Filter King 11.25x23.25x1 size air filters are tools used in your home’s air systems to keep the indoor air quality free of irritants. Your home may be subject to all kinds of airborne irritants due to high levels of pollutants and allergens. The incoming airflow needs to be kept clean, or the resulting problems will begin to affect an entire home over time. Your air filters are tools used in various air systems to keep the incoming airflow clean so that the old air cycles out and your home takes on a fresh clean smell. The filter will become dirty over time, and need replacement before they begin causing problems for your home.

Air filters that do their job correctly begin to build up captured particles in their tight mesh weaving over time. The particles begin to cover the mesh and eventually create a blockage that causes incoming airflow to become hindered or stop entirely. The accompanying air systems will try to bypass the blockage by increasing their energy usage. When more energy is used, your air system will cause a rise in billing and increased wear down for its various mechanical parts. Dirty air filters cause problems that only grow worse over time, and may lead to thousands of dollars in additional costs annually.

Filter King offers 11.25x23.25x1 size air filter replacements that keep the incoming airflow coming in and staying clean. Our 11.25x23.25x1 air filters have a MERV (Minimum Efficiency Reporting Value) rating of eight. Which means that the filters are capable of cleaning incoming airflow of particles such as:

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