Ultra-Filter Socks&#174; stop harmful substances from entering the stormwater system.  Use in front of storm drains, around downspouts, in gullies and ditches or anywhere there is potential for harmful stormwater runoff. Woven polymer casing allows water to pass through quickly while filtration media inside removes pollutants. Available in 9-foot lengths. High UV rating allows extended life sun and elements. Units can be overlapped for longer coverage or more than one filter sock can be used if the potential for more than one contaminant or a large quantity of a single contaminant is present.  Looped ends allow units to be staked in place and assist in transport. The Phos Filter is excellent for removal of phosphorous.  Helps comply with SWPP Regulations.  It is an EcoSmart product.
