Why Buy Air Filters From Filter King?


In comparison to fiberglass filters, 12x27x1 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 12x27x1 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.

12x27x1 Air Filter

Filter King 12x27x1 size air filters are tools used to create a protective layer inside of an air system. Your air filters consist of a tight mesh weaving that works to clean up incoming airflow of any airborne irritants. Filtration is necessary to keep the indoor air quality of your home from being affected by whatever level of pollutants or allergens that are in the surrounding air. Your air filters keep the incoming airflow clean, becoming dirtier as time goes on. Dirty air filters create problems and need replacement as soon as possible.

Your air filters need regular replacement or the effect becomes evident throughout your home. When the filters become dirty, they become a blockage in the air system that prevents natural airflow. When the air inside a home is unable to cycle regularly, then the air inside begins to stagnate and dry out. Your air systems will also become strained as they expend more energy trying to push the airflow forward.

New 12x27x1 air systems allow airflow to pass through while effectively keeping it clean at the same time. The filters rank as an eight on the MERV (Minimum Efficiency Reporting Value) scale. A filter’s MERV scale allows you to understand just how effective the filter is at cleaning up incoming airflow. With a ranking of eight, our 12x27x1 air filters are capable of blocking out irritants like:

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