These Odor Killer return air grill filters have been discontinued, but they've been replaced with our new and improved Gray Matter Odor Killer Odor Filters, which features a MERV 8 media impregnated with carbon to reduce odors plus harmful VOCs.
Filters Fast now offers its 5" Return Air Grille Filter with Odor Killer technology and a neoprene gasket, a MERV 8 two-stage carbon blended filter designed to "kill" odors such as cigarette smoke, pet odors, irritating gases from cooking and other bad odors affecting your indoor air quality.
The Merv 8 rating means this filter also effectively reduces pollen, dust, pet dander and other allergens from your indoor air. Removing these airborne particles can help improve allergies and alleviates sinus irritation that can cause watery eyes, itchy throat, coughing and sneezing.
Aside from the health benefits, having a Filters Fast Air Filter in your home will also extend the life of your heating and cooling system by making it work more efficiently, thereby saving you money on your power bill and limiting unnecessary repairs.
MERV, or Minimum Efficiency Reporting Value, indicates when a filter will be least efficient. So the higher the MERV rating, the more efficient the filter. It should be noted that most fiberglass spun filters such as those found in your local grocery store are usually only a MERV 1 or MERV 2.
In addition, the larger surface area and deeper pleats of the five inch filter make it 15% more effective at capturing airborne particles than a standard 1" filter. Pour 10 ounces of water into an 8 ounce glass and your cup runneth over. Pour that same amount into a 12 ounce glass, however, and you have plenty of room for more water.
Your air filter works in the same way. 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.
