Why Buy Air Filters From Filter King?


In comparison to fiberglass filters, 17.5x23.5x1n 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 17.5x23.5x1n 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.

17.5x23.5x1 Air Filter

Filter King 17.5x23.5x1 size air filters are tools used by air systems to clean out incoming airflow being pumped inside. Filtration is necessary to your home’s indoor air quality and ensures that the harmful irritants do not fill your ducts. The air filters are capable of capturing harmful irritants in a tight mesh weaving. Over time, the mesh weaving will become completely covered in the particles that it has drawn in. The dirty air filters are a problem that only grows worse over time, they require replacement, or your entire home will begin to feel the effects.

Your air filters will become dirtier over time, and eventually lose efficiency as they become covered in captured particles. The filters will become an issue as they become so full or captured irritants that airflow is unable to pass through efficiently. A lack of fresh airflow leads to indoor air problems of dryness and stagnation over time. Your air systems are also affected, becoming strained as they try to push airflow through the blockages.

Your dirty air filters cause mechanical problems which may require some costly repairs, along with a rise in energy billing. New air filters in a system will help keep the airflow coming in naturally while also keeping it clean. Filter King 17.5x23.5x1 size air filters are affordable tools for your air system, and we deliver them straight to your home. We also have a subscription service to have new filters shipped out as often as monthly. The filters rank as an eight on the MERV (Minimum Efficiency Reporting Value) scale, the filters are able to block out irritants like:

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

17.5x23.5x1 Furnace Filters

Filter King furnaces are necessary to preventing incoming heated airflow from also bringing in a number of irritants. The filters clean up the air after it heats up and before it goes into your ducts. Furnace filters eventually become dirty as well, but the effects have a serious impact on your home. There may be temperature fluctuations from room to room, as well as a rise in internal temperatures for the furnace. Eventually, there may be a need for costly repairs that are avoidable with new air filters. Order your filters today and help keep airflow coming in smoothly for all your air systems.
