Housings are designed to be used in conjunction with a wide variety of filters with varying efficiencies.

DriPak 2000 employs high-loft, layered, meltblown synthetic media that optimizes performance. Features ultrasonically-welded pocket spacers and edges. Available in four efficiencies: MERV 15 (90-95%), MERV 14 (80-85%), MERV 12 (60-65%) and MERV 8 (40-45%).

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.

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.

VariCel V's multiple mini-pleat media packs, assembled into a series of V-banks, permit substantially more media to be contained in the filter. Maximum effective media area provides greater airflow capacity, low resistance, high dust holding capacity, and unusually long service life. Available in 4 efficiencies; MERV 15, MERV 14, MERV 13, and MERV 11.

VariCel RF is ideal for Variable Air Volume (VAV) systems. Layered synthetic media with plastic pleat spacers on both sides and heavy-duty expanded metal media support grid make VariCel RF a durable, highly efficient filter.
