The Filter Sock stops harmful substances from entering the stormwater system. The woven polymer casing allows water to pass through quickly while filtration media inside removes pollutants. All units can be overlapped for longer coverage. The Filter Sock can be used in front of storm drains, around downspouts, in gullies and ditches, or anywhere there is potential for harmful stormwater runoff. The looped ends allow units to be staked in place and also assit in transport.
