These K Style Filter Flow XT gutter guards are a polyether foam filter insert. They prevent leaves, sticks, acorns, pine needles and large debris from getting into the gutters and downspouts and clogging up the water flow.

Backed by a 25 Year Warranty, the XT is a Contractor Grade product, and is rigorously tested for a worry-free, clog-free gutter guard. With a proprietary coating process, the XT has a UV stabilizer that prevents breakdown from the sun and is also fire retardant. It has germicides that inhibit the growth of mold, moss, algae, mildew, and fungus while preventing bess, wasps, and mosquitoes from nesting and breeding in your gutters.

Filter Flow XT gutter guards can not be seen from the ground and do not penetrate the roof in any way. They work on almost all different roof and gutter types and handle heavy rain falls.

Filter Flow XT Gutter Guards are available for k style and half round gutters for both 5" and 6" sizes.
