Product Information

Note: If you don't see your size we recommend the alternative FiltersFast MERV 13 (6-Pack).

The FiltersFast FFRAG13 reduces the following airborne contaminants:

  • Dust
  • Bacteria
  • Pet dander
  • Mold spores

Protect your health, your environment and your wallet with FiltersFast's MERV 13 Return Grille Air Filter.

MERV 13 is one of the highest efficiency ratings available, and FiltersFast now offers this rating in a 5" Return Air Grille application for an even more efficient filter. There is a reason the U.S. Green Building Council considers a MERV 13 rating the minimum level required to meet its Leadership in Energy and Environmental Design certification.

The advantage of a five-inch filter combined with a MERV 13 rating is twofold. First, the larger surface area and deeper pleats of the five inch filter make it 15 times more effective at capturing airborne particles than a standard 1" filter. You most likely have more airborne particulates in your air than your standard 1" filter is equipped to hold. Excess air particles can float back out into your household air and cause allergy flare-ups, sinus issues and other health problems.

Secondly, when you partner this larger filter with a MERV 13 rating you've got one of the market's most efficient filters. MERV 13 filters remove at least 90 percent of all particles 1.0 - 10.0 microns. To get an idea of just how big a micron is, check out the period at the end of this sentence. It's a whopping 397 microns.

All of this makes the filter particularly attractive to home owners, businesses, offices and hospitals hoping to improve their air quality while also limiting the wear and strain on their heating and cooling units, thereby wasting less energy and avoiding unnecessary repairs. The filter is also a quick and efficient way to achieve points toward your company's LEED Certification, which can qualify your company for tax breaks.

FiltersFast MERV 13 5" Return Air Grille Filters Specifications:

  • Manufactured with neoprene gasket
  • Reduces dust, pet dander, mold spores and bacteria
  • Removes at least 90 percent of all particles 1.0 - 10.0 microns in size
  • Causes less strain on heating and cooling systems
  • Rated MERV 13 per ASHRAE test standard 52.2
  • Fits most 1" residential wall or ceiling mount return grilles
  • Prevents dust bypass by pressure fitting into the frame
  • For both residential and commercial use
  • Only needs to be replaced once a year

The return air grille filter is 5" deep, and fits standard 1" size from the list below and then extends 4 inches into your return providing maximum filtration and efficiency. The FFRAG13 frames are available in the following sizes:

  • 12x24x5
  • 14X25X5

While the FFRAG13 may last up to three times longer than the standard 1" filter the frequency with which you need to change your filter depends on your indoor air quality. We recommend you change this filter every year or at the sign of a decrease in air flow.


The chart below will show you what you can remove with a MERV 13 return grill air filter, a MERV 11 return grill air filter, or a MERV 8 return grill air filter.
