SMART Filter Seal is a durable yet flexible high-strength film designed to fit tightly over the air filter slot on the return air plenum and prevent air from bypassing the filter and thus improves indoor air quality. Magnets surrounding the perimeter hold it tight against the plenum to prevent air leakage.

Covers and seals your attic stairs stopping air leaks, drafts, and energy loss.

Our Dryer Vent Seal will reduce unwanted air infiltration, and keep out pests, bees and rodents as well.

The green alternative to energy wasting attic pull down ladders.
