Silt Saver Curb Inlet Filter Conveniently sized weighted wattle for heavy-duty use.

The Silt Saver Curb Inlet Filter is a 7-foot long sediment control device placed in front of curb inlets to prevent silt and debris from entering storm drain systems, while still allowing stormwater to flow freely and prevent hazardous ponding on roadways. It combines a biodegradable pine straw core wrapped in high-visibility green polyester mesh with weighted end pockets to deliver effective, environmentally responsible inlet protection.

The Silt Saver Curb Inlet Filter uses a biodegradable pine straw core – enclosed in a high-flow polyester mesh casing – to filter out sediment as stormwater passes through, blocking particulate migration into the storm drain system while maintaining adequate water flow. Its weighted end pockets, filled with sand or #57 stone, anchor the device firmly in place at the curb opening.

Installation is straightforward: position the Curb Inlet Filter in front of the curb inlet, fill the end pockets with locally supplied sand or #57 stone to secure the filter and create a weir, then fasten with the included zip ties. The device is lightweight and flexible, making it easy to handle, haul, and deploy without specialized tools or equipment.

A single Curb Inlet Filter unit – measuring 9 inches in diameter with a 5-foot pine straw-filled center and two 1-foot weighted end pockets, totaling 7 feet in length – is designed to cover a standard 5-foot curb inlet opening. For wider openings, multiple Curb Inlet Filter units can be deployed side by side to provide continuous sediment protection across the full inlet width.

The Silt Saver Curb Inlet Filter is made in America from biodegradable pine straw fill, containing no rubber or sharp wire that could harm installers or introduce environmental contaminants into stormwater systems. Its adjustable weir – configurable from 3 to 9 inches using the weighted end bags – gives site managers precise control over stormwater release rates that many competing products simply do not offer.

Yes – the Silt Saver Curb Inlet Filter is specifically engineered to avoid environmental hazards, using biodegradable pine straw as its filtration core rather than recycled materials that can leach pollutants into waterways. The device contains no rubber components or sharp wire, eliminating the risk of secondary contamination in stormwater drainage systems.

Each Silt Saver Curb Inlet Filter kit includes the pine straw-filled curb inlet filter, two sandbag inserts, and zip ties for securing the device in place. Stone or sand for filling the weighted end pockets is locally supplied by the customer and is not included with the kit.

Unlike many traditional weighted wattles that use rubber binders or synthetic recycled fill materials that can degrade into waterway pollutants, the Silt Saver Curb Inlet Filter uses a fully biodegradable pine straw core that resists absorption, molding, and compaction over time. Its high-visibility green mesh casing also improves on-site safety in active roadway environments where standard brown or gray wattles are difficult to spot.
