D-Mark CarbonWeb LD Charcoal MERV 8 Pleated filters help remove odors from the air!

These filters are made with an odor absorbing carbon (coconut shell based) impregnated synthetic media, containing 8 grams of carbon per square foot. The frame is rigid, water-resistant beverage board. These charcoal pleated filters are also an effective particulate filter.

As opposed to non-pleated panel filters, pleats increase the surface area of carbon exposed to the air stream. For example, if you remove the frame and stretch out the pleated media of a 24x24x2 filter, it contains 14 square feet of filter media. Compared to only 4 square feet in a 24x24 non-pleated filter pad or flat panel filter.
