LeafFilter™ uses the most effective debris-blocking and water-handling technology in the history of the gutter protection industry! LeafFilter™ is the ONLY product that is able to absolutely guarantee that your gutters won’t clog.

XELA FilterShield, pronounced “Zeela,” is a remarkably efficient self-cleaning filtration membrane. It’s at the heart of LeafFilter™ success. It offers a unique approach to gutter protection which you won’t find in competing brands that rely on “reverse-curve” technology, perforations, or channels.

XELA FilterShield is made of stainless steel to prevent corrosion and it blocks particles larger than 5/1000 of an inch in diameter from entering your gutter.

XELA FilterShield creates a strong siphoning action that draws water into your gutter like crazy! Water has more density than most organic debris. If you place a bushel basket of pine needles, oak tassels, or other debris on top of LeafFilter™, the water will flow through and under the debris. It makes contact with the Leaffilter™ XELA FilterShield and, next thing you know, water is pouring out the downspout… NOT falling over a clogged gutter.
