The Ultra-Filter Sock® prevents harmful pollutants from entering the stormwater system. The filter sock is designed for use in front of storm drains, around downspouts, in gullies and ditches, or anywhere there is potential for harmful stormwater runoff. The filter sock has a woven polymer casing with recycled rubber media as a weight that keeps the unit in place and blocks sediment while allowing for the best possible water flow. The filter sock is 9' in length with looped ends that can be staked in place or overlapped for more coverage.
