Filter silt, sediment and other contaminants from stormwater inlets with weighted filter.

The Curb Inlet Filter by Spill Bully effectively protects curb opening inlets from debris and silt getting into the storm drain system. At 72” in length, the Curb Inlet Filter is longer than most single curb openings and provides complete coverage for the inlet. Built for durability, the Curb Inlet Filter is encased in high density polyethylene fabric, secured with 4 thread poly lock stitching with an 85% U.V. rating.

The Curb Inlet Filter is filled with aspen wood excelsior tightly rolled around a 3/4” PVC pipe with a coupler at one end to allow you to extend the filter. The PVC pipe allows it to hold its shape even in heavy rain. Two polypropylene straps connect the filter to a pouch of durable geotextile that is capable of holding up to 5 lbs of rock. The pouch, hidden from view inside the drain inlet basin, acts as a stabilizer for the filter that keeps it in place. For slopes and added protection, use silt bags on opposite ends.
