Product Information

Note: This filter is temporarily out of stock. We recommend the compatible Filters Fast Merv 11 (6-Pack).

The Filters Fast FFRAGF air filter can reduce the following from your indoor air:

  • Dust
  • Bacteria
  • Pet dander
  • Mold spores

The Filters Fast MERV 11 Return Grille Air Filter 5" are a great option for upgrading or replacing the traditional 1-inch air filter found in your home or office.

These Return Air Grille Filters are up to 15% more effective at capturing airborne particles than a standard 1" filter. The increased surface area of the 5-inch Return Air Grille Filter is what gives it the superior performance and efficiency.

An easy way to understand the concept is to imagine that you have 10 ounces of water that you need to pour out. Let's say, you have an 8 ounce glass and a 12 ounce glass. If you pour the 10 ounces of water into the 8 ounce glass, of course, the water is going to overflow and spill onto the floor. However, if you pour the 10 ounces of water into the 12 ounce glass you can meet your need and still have room for more water. Your air filter works in the same way. You most likely have more airborne particulates in your air than your 1" filter is equipped to hold. So what happens to the rest of the air particulates that the filter is not equipped to catch? They float back out into your household air and continue to cause allergy flare-ups, sinus issues and other health problems.

The deeper, pleats of the 5" Return Air Grille Filter offer more surface area and can capture particles as small as 0.3 microns.

The Filters Fast Return Air Grille Filter also:

  • Only has to be changed once a year and fits anywhere a 1" filter fits
  • Manufactured with neoprene gasket
  • Reduce dust, pet dander, mold spores, and bacteria
  • Cause less strain on heating and cooling systems
  • Are Rated MERV 11 per ASHRAE test standard 52.2
  • Fit most 1" residential wall or ceiling mount return grilles
  • Are Designed to prevent dust bypass by pressure fitting into the frame
  • Are good for both residential and commercial use

The FFRAGF comes in the following frame sizes:

  • 12X24X1
  • 14X25X1
  • 16X25X1
  • 20X25X1

The return air grille filter is 5" deep. It will fit a standard 1" size from the list above and then extend 4 inches into your return providing maximum filtration and efficiency.

While the FFRAGF may last up to three times longer than the standard 1" filter the frequency with which you need to change your FFRAGF filter will depend on your indoor air quality. We recommend that you change this filter when you notice a decrease in air flow or at least every 12 months.

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.

    Amazing filter!! Cut the dust in the house by about 1/2. The air flow from the cool air ducts was also increased!!! Living in the desert, with 2 dogs caused a lot of dust etc in the house. This filter cut that in half!!!!!!! Well worth the price fast shipping and easy to install.

    I installed this filter in a rental house that I own. It works great for me because I no longer need to trust the tenants to change out the filters. I just go once a year to change it out and have peace of mind knowing that I am protecting my air conditioner. I would change out on a shorter interval or vacuum every few months if you have dogs since thier hair can clog up the filter pretty fast.

    I have been in the business of Indoor Air Quality for many years now. This filter is incredible. It actually replaced my 1 inch filter and I know it will last a whole year in my home. This filter is 5 inches deep and fit into my one inch housing. There is no substitute for depth for energy savings.It works like the ducted home air cleaners for a lot less. Amazing filter. I can only immagine what the odor control can do.Try this for yourself.
