Actual Size of Air Filter: 17 1/2 x 35 1/2 x 3/4
Nordic Pure is now offering Pure Carbon AC Furnace Air Filters for eliminating odors in your home or office. Our activated carbon air filters consist of a durable non-woven polyester base media infused with a naturally derived charcoal that is treated with oxygen in order to open up millions of tiny molecular size pores between the carbon atoms. These pores are highly "adsorbent", forming a strong chemical bond, or attraction, to odorous, gaseous air molecules. Adsorption is the adhesion of atoms, ions, or molecules from a gas...to a surface. Nordic Pure carbon air filters contain 74 grams of activated carbon per square yard - yielding a surface area in excess of eight acres! In other words, air containing smelly gases, VOC's, pass through the activated carbon filter and the gas molecules will adhere to the carbon - allowing clean air to continue into your ac furnace air filter system.
