Why Buy Air Filters From Filter King?


In comparison to fiberglass filters, 12x26x1 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 12x26x1 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.

12x26x1 Air Filter

Filter King 12x26x1 size air filters are protective tools used to help make sure that incoming airflow is kept clean. The airflow your home air systems pump in is filtered to keep the irritants in the surrounding air out of your ducts and rooms. Filtration acts as the air systems way of cleaning out incoming airflow and raising indoor air quality. Your air filters are the tools your air systems need to clean up incoming airflow, but the tools do not last forever. The air filters become dirtier over time and will eventually require replacement to avoid any complications from developing.

The air filters in your home’s systems clean passing airflow by drawing airborne particles to become trapped in their tight mesh weaving. Your mesh weaving becomes so full of particles that it becomes unable to efficiently allow airflow to pass through. Without consistent airflow, your home will begin to suffer from old dry, and stagnant air. The old air is both unhealthy and uncomfortable to breathe in, and the air systems will suffer negative effects as well.

Your air systems will try to bypass dirty air filters by increasing the energy they expend to push the airflow forward. The resulting spike in electricity usage causes an increase in billing and creates greater strain on the air system. New 12x26x1 air filters have a MERV (Minimum Efficiency Reporting Value) rating of eight. The air filters are capable of blocking out particles like:

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