Marketing InformationPre pleat 62RM11 pleated panel filter enables a significant upgrade in collection efficiency over existing MERV 8 3 8 products at the same resistance levels. A 25 to 30% average efficiency filter can be upgraded to 60 to 65% efficiency at roughly the same resistance levels. Our next-generation ultrahigh-performance bi-component synthetic media contains mechanically engineered tri-lobal fibers with in homogenous domains of positive and negative electret charges within the bi-component fibers to equal an ultra-high-performance product.
