BioCel M-Pak offers the same media area and pressure drop as the BioCel I in a 6" deep, high-impact polystyrene cell side.

BioCel I® fills the gap between ASHRAE grade high efficiency filters and ultra-high efficiency HEPAs. Rated at MERV 16 by ASHRAE Standard 52.2, BioCel I has the advantage of much lower pressure drop than a typical HEPA filter (0.4" versus 1.0" w.g. at 250 FPM). Available in 6" or 12" depths.

AAF HEPA and ULPA filter products feature a broader selection of efficiencies, cell side materials and configurations, and separator designs and bonds than any other manufacturer. Every AstroCel filter is individually tested before it leaves the factory to ensure that it meets rated efficiency.
