The synthetic media handles high-moisture applications well, the progressively-dense media construction maximizes dust holding capacity, and the self-sealing design prevents air bypass at the frame edges.

This makes the MG550 a strong choice for installations where captured biological material would otherwise become a substrate for microbial growth over the filter’s service life — healthcare environments, food processing, hospitality, and any high-occupancy commercial building. The antimicrobial treatment protects the filter media itself; it does not actively kill airborne pathogens passing through the filter.\u003c\/p\u003e\u003ch3\u003eChoosing across the Maxi-Grid line\u003c\/h3\u003e\u003cp\u003eKoch offers four Maxi-Grid Standard Panel sub-lines, each tuned for a different application:\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMG200 (MERV 7):\u003c\/strong\u003e Most economical, 3-ply, downstream tackifier.
