The VariCel II MH filter is constructed using the same high standards for efficiency and performance as the original VariCel II filter. The microglass paper media with water repellent binder and the minipleat design are also the same as the original.

The difference is that the VariCel II MH filter is built with metal cell sides. It includes a metal header with rolled edges for safe handling and uses AAF Flanders’ unique interlocking cell sides and header. 

The combination of unique design and metal cell sides and headers means that the VariCel II MH filter works well in turbulent operating conditions and in environments where high moisture content is an issue. When combined with the water repellent binder used in the media, the metal construction makes the VariCel II MH filter highly moisture resistant. In addition, the metal header model makes it an easy fit in side access systems.

Available with Antimicrobial

The VariCel II MH filter with antimicrobial is available in MERV 14, MERV 13, and MERV 11 efficiencies. Antimicrobial acts as a preservative to ensure the integrity of the media throughout the life of the filter. EPA registered and environmentally safe, antimicrobial inhibits the growth of microorganisms documented to affect IAQ.

Slim-Line Design

The slim-line design of the VariCel II MH filter provides minimum resistance and maximum dust loading capacity, while lowering operating costs. Rows of adhesive beads are used to maintain even pleat spacing and provide maximum airflow with minimal resistance. The consistent pleat spacing of the media allows higher dust holding capacity and full use of the entire depth of the media.

Dual-Density Media Increases Dust Holding Capacity

The VariCel II MH filter uses microglass paper media with a water repellent binder. The fibers are formed with dual-density construction, consisting of coarser fibers on the air entering side and finer fibers on the air leaving side. This design allows for collection of particulate throughout the full thickness of the media, substantially increasing dust holding capacity. The media is water repellent and can withstand intermittent exposure to water without affecting performance.
