Why Buy Air Filters From Filter King?


In comparison to fiberglass filters, 20x32x1 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 20x32x1 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.

20x32x1 Air Filter

Filter King 20x32x1 size air filters are used in your home air systems as tools to keep airborne irritants out. The process continues constantly as your air systems continue to pump in air, leading to a rise in indoor air quality over time. The air around your home may contain any number of allergens or pollutants capable of making the air inside of your home uncomfortable or unsafe. Your air filters consist of a tight mesh weaving designed to allow airflow to pass through naturally, while particles become captured or absorbed in the process. However, the filters eventually become dirty as they continue to absorb irritants and end up becoming a problem for your home.

The air filters in your home inevitably become dirty, which means their mesh weaving becomes completely covered in captured particles. Airflow is unable to effectively pass through dirty air filters, which leads to a lack of fresh airflow for your home. Without fresh airflow, your home suffers from dryness and stagnation over time. Your air systems will try to push airflow past the blockage, but this will strain them over time. If the filters in your home are not replaced frequently, you may need to face issues of mechanical damage and increased energy billing over time.

Dirty air filters only grow dirtier over time when they are not replaced. Filter King offers replacement 20x32x1 size air filters available for purchase and ready for use upon arrival. Delivery services are also ready to have your new filters brought right to you, with orders of two or more filters shipped out for free. For more frequent orders, we have a subscription option ready so new filters are shipped out to you as often as monthly. Our filters rate as an eight on the MERV (Minimum Efficiency Reporting Value) scale. This means that they filter out particles like:

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

20x32x1 Furnace Filters

Your home furnace needs furnace air filters in order to make sure that the airflow coming in does not pollute your systems. These filters clean out airflow after it becomes heated but before it distributes into your home. The filters become dirtier over time and require replacement before the heated airflow begins to build up. If not replaced, the rise in internal temperatures lead to issues of mechanical damage and heat fluctuations. Order new air filters today to enjoy fresh airflow for home and avoid several problems for its systems.
