Our Geothermal MERV 10 Plus Carbon odor control air filters are made with a 1 piece frame for strength and stability so no taping, stapling or gluing filters together. The sturdy one piece frame and extra material makes it a high capacity filter which really enhances it’s performance. Nordic Pure's Geothermal MERV Pleated Plus Carbon air filters work with your geothermal heat pump system to remove airborne particles and help eliminate odors in your home or office. The MERV media captures microscopic airborne dust, pollen, allergens, mold spores, pet dander, bacteria and particulates carrying bacteria, and viruses in the air for better indoor air quality. The high quality activated carbon media naturally deodorizes the air by absorbing and eliminating household odors that may come from pets, garbage, bathrooms, smoke, litter boxes, or cooking. It also removes levels of concentration of gases (VOC's) as well as particulates in the air while maintaining excellent air flow properties. These MERV plus activated carbon, odor reducing geothermal air filters consist of a durable non-woven polyester MERV rated media infused with a naturally derived charcoal. Our filters are manufactured using a heavy duty, moisture resistant beverage board frame. There is a metal mesh support grid bonded to the pleats for extra support. The air filter media will not support the growth of mold or bacteria.
