The FILTI® permanent washable filter uses specialized nanofiber technology to offer a MERV 13 efficiency rating. The FILTI® filter does what other washable filters cant; providing permanent, high efficiency filtration. The FILTI® filter provides 3 layers of protection - LAYER 1 - meltblown layer designed to capture larger particulate matter and engineered for increased dust-holding capacity / LAYER 2 - patent-pending nanofiber technology captures the smallest particles and ultra-fine pollutants  / LAYER 3 - downstream scrim acts as a supporting layer for the nanofiber and provides additional reinforcement
