The four progressively dense layers each capture a specific particle-size range — coarser particles in the upstream layers, finer particles in the downstream layers. This staged capture also extends service life by distributing particle loading across all four layers rather than overloading the first layer. The trade-off is the higher initial pressure drop (0.48″ w.g.); confirm your blower can handle this resistance before specifying.\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.
