Tjernlund Products 950-0485 Prefilter For PAI-7 Enforcer

The Tjernlund Products 950-0485 Prefilter functions as an HVAC application prefilter designed to operate with the TJERNLUND PAI-7 Enforcer powered air intake system specifically intended for tightly sealed homes and homes with combustion appliances. The prefilter positioned at the front of the PAI-7 system traps significant airborne particles starting from dust through pollen and debris before they enter the main filter. This filtration process prevents significant damage to the main filter while bettering indoor air quality thus maximizing overall system performance of the PAI-7.
