Why Buy Air Filters From Filter King?


In comparison to fiberglass filters, 13x18x1 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 13x18x1 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.

13x18x1 Air Filter

Filter King 13x18x1 size air filters are useful tools used by your air system to prevent incoming air from causing problems for your home. Without air filters, your home may be subject to a full range of airborne pollutants and allergens. Your air filters consist of a tight mesh weaving made to trap and absorb irritants out of passing airflow, so they do not become a problem. The indoor air quality of your home is raised by having clean filters in place, but they do not remain clean forever. Eventually, your filters will become dirty and require replacement to avoid complications from developing in your home.

When the air filters in a system are dirty then the resulting effects on a home become an evolving problem. Airflow cannot effectively travel through dirty air filters, which means that the air inside does not cycle out leading to dryness and stagnation. Your air systems will attempt to bypass the blockage by increasing their energy use, which lead to a rise in your energy billing. The spike in electrical usage will also cause a severe strain on your air systems leading to mechanical damage as well.

When you install new air filters you avoid billing that could have cost your home thousands annually. Our 13x18x1 size air filters are affordable and provide your home air systems with a much needed layer of protection. Filter King 13x18x1 air filters have a MERV (Minimum Efficiency Reporting Value) rating of eight. The filters are able to block out irritants like:

  • Pollen
  • Dust
  • Mold
  • Dust Mites

  • Viruses
