Festool Selclean Filter Bag for CT 36, Pack of 5 - Keeps Suction

In this review of the Festool SELFCLEAN filter bag for the CT 36, the bottom line is simple: this pack of five bags is for professionals and serious hobbyists who need consistent extraction performance and clean disposal. The single biggest reason to buy is the self-cleaning design, which prevents dust caking inside the bag and preserves suction efficiency during long jobs. The reviewer found the bags well constructed, effective at keeping fine particulates out of exhaust, and convenient to seal and dispose of after use.

Key Features

• Self-cleaning design: Prevents dust from caking on the inner lining so suction stays consistent across extended sessions.
• Five-micron capture: Acts as a pre-filter that traps particles down to five microns to reduce dust in the extractor and exhaust.
• Integrated disposal flap: Allows the bag to be sealed quickly and cleanly for safer handling and reduced exposure when throwing it away.
• Single-use convenience: Designed for single use so users can remove a full bag and replace it without cleaning delicate filter elements.
• Compact package: The pack dimensions are compact, making storage and transport easier for jobsite use.

Who It's For

These filter bags are best for tradespeople, woodworkers, and renovators using a compatible CT 36 dust extractor who value uninterrupted suction and easy, sanitary disposal. If you run long sanding or demolition sessions where fine dust builds up, the self-cleaning effect preserves performance and keeps the extractor working efficiently.

If you need reusable, washable filtration for frequent heavy use or very fine HEPA-level filtration beyond five microns, consider a permanent filter or HEPA upgrade in addition to these bags; these Festool bags are intended as single-use pre-filters that prioritize cleanliness and disposal convenience.
