Filter Flow Half Round Polyether Foam Gutter Filter

These half round Filter Flow gutter guards are a polyether foam filter insert that prevents leaves, pine needles and large debris from clogging a gutter system.  Leaves and debris slide off the surface or just dry up and blow away.

Filter Flow has a Proprietary Coating Process that has a UV stabilizer that prevents degradation from the sun.  It includes a germicide that inhibits the growth of mold, mildew, fungus, algae and moss.  It also prevents mosquitoes, wasps bees and other insects from breeding in the gutter.
