There is no cardboard frame to warp or become a food source for mold and bacteria, no 20% blow-by allowing air to go untreated and unfiltered, and no replacement for three months, or more in clean environments. The unique design of the BLS PerfectFit provides an internal frame sandwiched between two layers of anti-microbial treated MERV 7 media allowing free airflow that will not strain your air conditioner. Plus it has side-to-side flush edges to insure that all the air is filtered and treated. This filter keeps your air conditioning system cleaner and reduces the possibility of mold and mildew growth on the duct system.
