The VariCel® M-Pak is a "midi" pack, extended media surface filter for higher-efficiency applications. With a depth of 5/8 inches, the filter delivers the same efficiency, pressure drop, and service life of a 12-inch-deep filter, said the company. Three efficiencies are available: MERV 11, 13, and 14. The MERV 11 and 14 filters are available with antimicrobial. The filter media has a dual-density, wet-laid fiberglass design. Thermoplastic separators maintain uniform spacing between pleats to allow optimal airflow into and through the filter. The media pack is fixed in place with a poured polyurethane seal.
