Why Buy Air Filters From Filter King?


In comparison to fiberglass filters, 14x25x5 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 14x25x5 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.

The Honeywell FC40R1045 14x25x5 Replacement Grille Filters replaces the Expandapac filter #FC35A1118 that was used in model F35R1069. This product is a grille filter and has a nominal size of 14" x 25" x 5". The actual size is 13 3/4" x 24 3/4" x 4 3/8".

These filters are a high-efficiency alternative to one inch filters because they have a larger media capacity, which allows for greater dust holding ability. There is no assembly required for this product, it simply inserts into and out of the existing return grille.

They also allow you to replace your old filter with ease, without having to remove the grille, simply push it aside. Please note that this product will allow a 7" depth behind grille to provide space for the deeper filter and air flow through filter. These filters last up to 6 months or more depending on use.
