MERV 7 pleated filter with patented media, pleat design and manufacturing process resulting in a state of the art product. Self supporting DuraFlex media requires no wire supports. The pleat design ensures perfectly shaped and spaced pleats. The automated process eliminates inconsistencies and irregularities in the filters.

PerfectPleat ULTRA incorporates antimicrobial treated media for superior performance in high moisture conditions. PerfectPleat ULTRA is rated MERV 8.

VariCel filters are rigid, self supporting filters with dual density media. VariCels are available in three efficiencies MERV 14, MERV 13, and MERV 11. VariCels are available in 6" or 12" depths. Also offered with antimicrobial in 90-95% & 60-65% efficiency.

VariCel II’s slim line design provides minimum resistance with maximum dust loading capacity. VariCel II filters are available in three efficiencies MERV 15, MERV 14, and MERV 11. The VariCel II M & MH combine the efficiency and performance of VariCel II media with AAF’s unique interlocked metal header and cell side.

A 6"-deep (nominal) filter with the same media area and performance, but half the weight as 12"-deep (nominal) filters. Available in MERV 14, 13, and 11 efficiencies.
