The over-the-grate storm drain filter is a low-profile, traffic-ready solution for managing sediment, debris, surface oils, and mosquito control in stormwater systems. Designed for use on city streets, construction sites, and industrial locations, this flat drain cover installs quickly without removing the grate. Built-in magnets secure it firmly in place. Its geotextile fabric traps pollutants before they enter the drain, helping meet NPDES compliance goals while reducing maintenance. The design also blocks mosquito access and supports chemical-free vector control strategies. Made from UV-resistant, tear-resistant monofilament, the filter withstands weather and wear.
Our durable outdoor drain filter is made from 10 percent monofilament geotextile material.
