ProTemp Heater Filter Kit

The filter kit consists of the air filters needed to keep dust and debris out of your heater's rotor. The kit contains the air filters for the rotor and a new filter gasket. The filters should be inspected often, and replaced when they show signs of dirt buildup. Clean filters allow for unrestricted air flow and better performance.

Let's get started.
