The mini pleat "V" construction of the "Quality Cell" V cell incorporates 150 square feet of media in a 24 x 24 x 12 filter. This tremendous amount of media allows for lower pressure drops, longer service life, and high efficiency. The entire frame, media, and media separators are constructed of plastic making "Quality Cell" V cell resistant to moisture damage. High blowout resistance makes this an optimal choice for high air velocity applications. Available in ASHRAE 52.2 (MERV) ratings up to 14 (equivalent to 52.1 @ 95%).
