A washable, reusable filter bag that replaces the disposable bags in your Festool extractor. Empty it, shake it out and carry on — instead of buying another pack every few weeks.

Three layers of high-strength polyester fleece with an inner microfleece membrane and a non-stick inner face, so dust drops out cleanly rather than clinging to the walls. The collar is cut to fit CT 25, so there is no gap for fine dust to slip past.

Made for dry waste: dirt, wood chips, sawdust and general site debris. It will cope with plasterboard and concrete dust, but those shorten its life considerably.
