Why Buy Air Filters From Filter King?

Image

In comparison to fiberglass filters, 12x24x5 pleated air filters are at least 20 times more effective. All Filter King air filters are made in the US.

Image

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.

Image

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 12x24x5 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 FC40R1037 12x24x5 Replacement Grille Filters are an excellent alternative to one-inch filters. With their high surface area, they can efficiently trap particulates that threaten your air quality. This product is compatible with the previous model by Honeywell F35R1036 and replaces part number FC35A1076. The nominal size is 12x24x5 (11 3/4 x 23 3/4 x 4 3/8), but it has a less restrictive design which allows for minimum restriction of airflow through the filter media - making this an energy efficient solution.

No assembly required; easily inserts into and out of existing return grille.
