Drain & Inlet Filters

Storm Drain and Inlet Filters

Inlet protection keeps sediment, trash and oil out of storm drains while letting water through. Pick the product by the type of inlet you're protecting.

  • Drain guards: inserts that hang under a grate in a catch basin.
  • Curb inlets: Inlet Guard Plus curb style models with an overflow port so heavy rain doesn't back up the street.
  • Street drains: grate only inlet guards and inserts for drains in the roadway or lot.
  • Grate guards: filters that sit on top of the grate.
  • Pipe socks: filters for pipe outlets, sized by pipe diameter.
  • HydroKleen media filter bags for heavy metals and oil.

How to choose

Measure the grate or curb opening, decide whether you're catching sediment only or oil too, and check whether the inlet sees heavy flow. Overflow ports matter on inlets that take a lot of water in a storm.

Read more: our storm drain filter guide matches each filter to the inlet type and the pollutant you need to catch.

Stormwater items are usually in stock and arrive in about 7 to 10 business days. Request a quote for a site wide order.
