Purolator Air Filter Defiant Bag

Purolator Air Filter Defiant Bag

Purolator's DEFIANT, 70% MERV 12, 85% MERV 14, and 95% MERV 15 media meets today's ASHRAE challenges in process control and contaminant reduction in this Purolator air filter. The unique, patented non-woven process used to manufacture a DEFIANT Purolator air filter creates a media which outperforms similar products with respect to initial efficiency, average efficiency, and dust-holding capacity.

The continuous hydrophobic fibers which make up DEFIANT media do not absorb moisture and are thermally bonded to eliminate the need for chemical containing binders that could promote microbial growth or generate VOCs. Both characteristics create a durable bag filter able to withstand turbulent, high-velocity conditions, even when high humidity is a factor.
