Ultratech, Inc. 9453 FilterSock Activated Carbon Green personal protective equipment

What the FilterSock is and who it serves

The ULTRATECH 9453 FilterSock is a ten-foot-long, seven-inch-wide, four-inch-high woven geotextile sock filled with activated carbon. It is designed for storm drains, downspouts, gullies and ditches to help remove certain chemicals, hydrocarbons and odours from flowing water. The green HDPE construction provides durability for outdoor drainage applications.

Who this suits and who should look elsewhere

This FilterSock suits site managers and maintenance crews needing passive filtration at surface-water inlets where oil capacity is not a rated requirement. It is not for buyers who need a product with a stated oil-absorption capacity, a different length or width, or a certified removal efficiency for specific regulated contaminants.

How it fits into a drainage setup

The sock lays directly into or across the target drainage feature and relies on gravity flow through the geotextile and carbon media. It frees up the need for powered treatment at the inlet and works with existing grate or open-channel configurations. No additional hardware is included, so anchoring or framing must be sourced separately.
