Key Features
Built for CT 36This Festool 496121 Longlife Filter Bag for CT 36 is made specifically for Festool CT 36 dust extractors, so fit and sealing are matched to the machine instead of being a generic workaround. Reusable up to 500 TimesInstead of tossing a disposable bag after one use, this reusable dust bag can be filled and emptied up to 500 times. That cuts consumable cost fast if you regularly collect coarse debris. Made for Large DebrisThe 3-layer polyester fleece construction is intended for large chips and non-hazardous dust, helping protect the extractor’s main filter and keeping cleanup more controlled during bag removal.
Overview
Festool 496121 Longlife Filter Bag for CT 36 is a reusable dust extractor bag made for Festool CT 36 dust extractors. This is a longlife filter bag designed for collecting large chips and non-hazardous debris while reducing how often you replace disposable bags. Model Number: 496121.
What matters here is where this bag fits in the system. It traps larger chips and debris before they reach the main filter, which helps extend the service life of both the main filter and the dust extractor. If you do a lot of cleanup from planing, routing, sanding setup waste, or general shop debris where the material is coarse rather than fine, that can save real maintenance time and ongoing bag cost.
The big advantage over a standard disposable filter bag is reuse. Festool states this bag can be filled and emptied up to 500 times before replacement. For users who regularly collect bulky debris, that makes this a practical shop accessory rather than a one-and-done consumable. It is built from high-strength, 3-layer polyester fleece for longer service life and repeat emptying.
Festool also adds an integrated cap that forms a tight seal during bag removal and disposal. That is a small detail that matters in real use because it helps keep collected material contained instead of spilling onto the floor when you pull the bag from the extractor. It is a cleaner setup for shop maintenance and jobsite cleanup.
Just as important, this bag has a specific use case. Festool recommends it only for large chips and debris, and notes that it is not recommended for fine dust. It is also not intended for RRP tasks and is used only for extraction of dust types that are not hazardous to health. In plain terms, this is the right accessory when you want a reusable bag for coarse material, not a catch-all solution for every dust application.
Compatibility is straightforward: this bag is suitable for Festool CT 36 extractors. If you are already on the Festool dust extraction platform and want a cost-effective alternative to disposable bags for the right kind of debris, this is the purpose-built option. It makes the most sense for cabinet shops, remodelers, carpenters, and serious DIY users who want to cut recurring consumable cost without giving up a proper machine-specific fit.
Reusable Dust Collection for Coarse Debris
