Koch Filter Corporation now offers Multi-Pleat GREEN 13, which is a high efficiency extended surface pleated panel filter. The filter has been engineered to provide higher initial efficiencies and better overall performance than standard pleated filters, the company says. The Multi-Pleat GREEN 13 carries a MERV 13 fractional efficiency rating in accordance with ASHRAE Test Standard 52.2, which 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 company says.

Additionally, the company is making available three guides on choosing air filters:
