The Koch Multi-Pleat Green MERV 13 is a high efficiency extended surface pleated panel filter and is a sustainable component of green building development.
By virtue of its MERV 13 performance rating, the Green 13 can earn points toward LEED certification in the US Green Building Council's Green Building Rating System. (LEED is Leadership in Energy and Environmental Design, an integral part of the rating system). The media in the Multi-Pleat Green 13 is produced with a specialized blend of electrostatically-charged synthetic fibers. This layer of polypropylene fibers, known as the E-Layer, is composed of rectangular shaped fibers arranged in an intersecting cross-pattern design. This unique fiber configuration insures greater stability of the electrostatic charge, reduced pressure drop, and prolonged efficiencies compared to other filter media.
