Stop sediment and other pollutants from entering stormwater drains.


The Ultra-Filter Sock represents the ultimate in above-drain stormwater protection. With the different filter media options available, our filter sock is capable of removing many different types of sediments and pollutants. In fact, it is the only product with this versatility. The 9-foot-long filter socks are placed in front of storm drains. The woven geotextile material allows stormwater to flow through into the storm drain while the media inside of the filter sock removes pollutants.
