Protect your health, your environment and your wallet with Filters Fast's MERV 13 Return Grille Air Filter.
MERV 13 is one of the highest efficiency ratings available, and Filters Fast 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.

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.
