Air Filter, 12x24x4 DMK80 - MERV 8 (3 Pack), Purolator, Mfr#: 12x24x4x1 DM (3 Pack)

The Defiant Mark 80-D (DMK) is a medium efficiency pleated filter. The 100% hydrophobic synthetic media provides nearly 95% average resistance .21 Initial Resistance (In. W.G.). The DMK is effective as a stand-alone filter or prefilter. All DMK filters are made with sophisticated production control techniques to ensure consistent pleat count, height, shape, and spacing. This uniform spacing contributes to a better-performing pleat with low pressure drop, full depth dust loading, and longer service life.
