Why Buy Air Filters From Filter King?


In comparison to fiberglass filters, 13.25x13.25x1 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 13.25x13.25x1 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.

13.25x13.25x1 Air Filter

Filter King 13.25x13.25x1 size air filters in an air system to keep the incoming air clean and clear of airborne particles. The level of pollutants and allergens surrounding your home are capable of severely impacting its indoor air quality. Your air filters consist of a tight mesh weaving that allows airflow to pass through naturally while becoming cleaned in the process. The said process also causes the air filters in a system to become dirtier over time, which creates blockages in a system that come with a series of complications.

Dirty air filters in your home only cause problems, these problems only grow worse over time as the filters become dirtier. The airflow pumped into your home is unable to pass through dirty air filters easily, which may stop air from cycling throughout your home entirely. When air cycling stops, the old air trapped inside dries out and stagnates which makes it unhealthy to breathe in. Dirty air filters also cause complications with additional billing and increased strain on their air systems.

New air filters may save you up to thousands annually on costs that are easily avoided when airflow is easily allowed into your home. We deliver new 13.25x13.25x1 air filters that allow airflow to pass through while effectively cleaning it. Filter King air filters have a MERV (Minimum Efficiency Reporting Value) rating of eight.
