A method and apparatus for filtering open drains, such as rain gutters, uses at least one elongated tube constructed from a plurality of strands of flexible, resilient, durable, corrosion resistant material. An affixing system removably affixes each of the elongated tube in the open drain. A method and a kit for filtering open drains also are disclosed.


A gutter filter, comprising a plurality of interwoven, resilient plastic fibers positioned in a grid array and interconnected at intersections of the fibers so as to form an elongated, substantially cylindrical, seamless, resilient and substantially closed, perforated tube having two open ends, wherein the fibers define a grid surface having plurality of substantially radially directed apertures for passage of fluid therethrough, whereby the filter can be positioned in an elongated gutter so as to substantially allow passage of fluid through the grid sur...
