Leaf Filter

Offering residents of greater Seattle and Tacoma the most advanced gutter protection system, LeafFilter guarantees that its product will effectively keep out debris, providing a full money-back guarantee on the purchase price should clogging ever occur.

LeafFilter was established by an American executive with over a decade of experience in corporate best practices in Japan. On his return to the United States, he searched extensively for a product that would significantly outperform other gutter protection systems in the Puget Sound’s difficult climate. He finally settled on LeafFilter after discovering that other systems, while effective against broad maple leaves, simply could not keep out evergreen and fir needles. LeafFilter does.

LeafFilter is manufactured from long lasting exterior-grade PVC, with a surgical stainless steel micro-filtration system that prevents corrosion. Spanning the gutter completely, the product appears as a solid cover. Holes of less than 50 microns in diameter keep out insects, grains of sand, dirt, and shingle grit, while filtering in rainwater. This water is quickly dispersed through comb-like grooves after initial filtration, with the PVC adding another filtering stage. The system comfortably handles 10 inches of rainfall per hour on standard shingle roofs, an amount larger than most roofs will ever see. With a sturdy I-beam and bracket construction, stability is more than sufficient. 

LeafFilter compares favorably to other systems, with Consumer Reports rating it THE top professionally installed gutter guard in terms of debris intake and flow. The product’s K.T.S.O. rating is similarly high, with LeafFilter achieving a pacesetting rating of 97 out of 100. The K.T.S.O rating scale assigns pollen particles a value of 100, grains of sand a value of 80, and fir needles a value of 60. A 97 rating means that only pollen poses a possible issue, with LeafFilter requiring possible cleaning in high-pollen areas. Homeowners can easily clean the system using a light pressure washer, or by calling the company to request a complimentary service call. 

LeafFilter’s professionally trained employees are all fully insured, licensed, and bonded, and offer a free estimate on installation projects. Knowledgeable custom builders and roofers recommend the product more than any other professional system. LeafFilter maintains longtime memberships in the Better Business Bureau and the Master Builders Association.
