Genuine Brand ODOR DEFENSE® Air Filter With Gray Matter®

What is Gray Matter?....See for yourself here.

According to the
American Lung Asso
., the EPA, and other government agencies, VOC's can cause cancer and other illnesses. VOC's are in your home! ODOR DEFENSE® can capture many of them.


Gray Matter® is a next generation, high-tech filter media which uses highly advanced technology for particulate and molecular filtration. It was designed specifically to capture the harmful molecules that are in the air of homes and other buildings where people live and work. Gray Matter uses a proprietary sub-micron technology making it the best filtration media on Earth.

Gray Matter uses sub-micron carbon particles that are hundreds of times smaller than the carbon used in other carbon filter media. For this reason, Gray Matter is 3 to 5 times more effective in capturing gaseous substances than standard carbon filters. These sub-micron carbon particles impregnated into a white filter media is what makes the filter look gray.

VOC's (Volatile Organic Compounds) commonly known as odors or gases are in your home and come from many sources. The American Lung Association states that these invisible gaseous irritants can cause allergies, asthma, irritate the eyes, nose and throat, and can cause difficulty breathing. Some of these toxic gases can damage the central nervous system as well as other organs. Some VOCs can even cause cancer over the long term. Children and the elderly are much more vulnerable to the negative effects of VOC's.

ODOR DEFENSE®, our gas absorbent air filter, was designed specifically to fight these harmful and dangerous Volatile Organic Compounds. ODOR DEFENSE uses Gray Matter exclusively on all our carbon impregnated air filters. To order ODOR DEFENSE, go to the menu on the left, and then to your filter brand.
