Frequently Asked Questions

The Ultra-Filter Sock has several distinct advantages that could prove to be a deciding factor in choosing it to protect your drain from incoming pollutants.  (1) Ease of use and installation – with the Filter Sock, you simply lay it down in front of a drain or inlet.  No hardware to install, no heavy grates to lift.  (2) Versatility – the Filter Sock has multiple filtering media options available which enables it to remove pollutants that a lot of other stormwater products cannot remove.  (3) Multiple media options – not only are there several media options available but you can use them together in a “treatment train” so you can filter out many different pollutants.

If a “clean” installation is a significant concern or the Filter Sock could pose a tripping threat to pedestrian traffic or an obstruction for street sweepers or other equipment, it may not be the ideal solution.

Since the Ultra-Filter Socks are only available in one length (9′), you can simply use multiple units when more than nine feet is required.  It is recommended that you overlap units to insure complete coverage/protection.
