A drain filtering device is disclosed. The improvement over the prior art is comprised of reducing the filter size from an elongated device that spans the length of the gutter system to a modular unit which is necessary only at the drain sight. The invention also includes an inclined upper face which is positioned on the upstream side of the drain in the gutter and a down spout attachment which locates the invention in the gutter such that the flow of filtered water passes through the invention and into the downspout. The debris that collects in the gutter is carried along the with the water until it makes contact with the inclined upper face and is forced up the incline until the overflow debris flows over the side of the gutter thereby cleaning same and preventing the downspout from becoming clogged.
