A drain basin filtering device, located within a curb side storm water inlet basin, wherein said basin further comprises at least one pair of opposing interior surfaces, comprising:

• a) a funnel comprising a first plate and a second plate, said first plate laying on top of said second plate, said plates each having an outside edge and an inside edge, said outside edge having a filter bag support member rest, wherein said plates interlockingly fit and are slidably in relation to each other;
• b) an expandable structural support member, said structural support member, having a first and second distal ends, said first distal end attached proximate to said plate's outside edge, said member further comprising screw means to urge said second distal end and said plate to exert opposing forces against said opposing pair or interior surfaces of said curb basin;
• c) a filter bag support hook, said support hook being arranged and restrained proximate to said second distal end of said support member;
• d) a filter bag assembly, said filter bag assembly comprising a filter bag having an upper periphery, an open top, and a closed bottom, and a pair of support sleeves located at said upper periphery;
• and
• e) a pair of bag support members each member having a first end and a second end, said bag support members being inserted into said support sleeves, wherein said bag assembly is suspended within said basin between said structural support members by resting said first end of said bag support members on said filter bag support member rest and resting said second end of said bag support member on said filter bag support hook.
