The Multi-Pleat XL8 is a medium efficiency extended surface pleated panel filter, engineered to provide higher initial efficiencies and overall superior performance than standard pleated filters. The Multi-Pleat XL8 media is produced with an optimal blend of highly specialized fibers, developed specifically for use in extended surface air filters. Developed to deliver a "one of a kind" performance, this specialized media operates on mechanical filtration principles which provide high efficiency, low pressure drop and high dust holding capacity. The Multi-Pleat XL8 maintains a MERV 8 performance rating before and after conditioning steps when tested in accordance to ASHRAE Test Standard 52.2-2012.
