Green 13 4" 25x29x4 (Qty 6)

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 MERV 13 performance ratings provided by the Multi-Pleat GREEN 13 make the filter an excellent upgrade from disposable filters and ordinary pleated filters in applications such as hospitals, laboratories and pharmaceutical plants, commercial office buildings, and in any system in which a higher degree of clean air is required.

• The media in the Multi-Pleat Green 13 is produced with a specialized blend of electrostatically-charged synthetic fibers, researched by Koch Filter Corporation specifically for use in extended surface air filtration.
• 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.
