1. Medium efficiency filter media mainly filters the dust and particle which is above 1μ m as the secondary or terminal filtration after the pre filtration. This medium filter media can be made into panel filters and pocket filters.

2. This medium efficiency filter media is made of high-quality super-fine melt-brown synthetic fiber with progressive density, and without organic silicon. This ceiling filter is especially used in spray booth with an optional antimicrobial agent applied to prevent the growth of bacteria as filtering particle ≥ 1.0μ m at the efficiency of 40% - 60%.
