A modular curb inlet filter apparatus having an internal axial tube member on which are disposed at least two disc spacers, which in turn support a cylindrical mesh frame member, which in turn supports a tubular filter fabric. Wedge anchors composed preferably of a compressible polymer foam are provided with anchor bores of sufficient diameter to receive the ends of the cylindrical mesh frame member therein, the anchor bores being disposed near the base of the wedge anchors such that the curb inlet filter inlet apparatus will be seated close to surface of the curb inlet base when positioned within the curb inlet. Preferably the wedge anchors are provided with a base scuff plate made of a durable polymer material to prolong their use life. A short silt flap or skirt depends from the filter fabric, the silt flap extending the approximately the length of the curb inlet filter apparatus to seal any gap beneath the curb inlet filter apparatus and the base of the curb inlet. Connector fitting members are provided such that the axial tubes may be connected end-to-end in modular manner to create longer structures.
