The Festool 496120 Longlife Filter Bag for CT 26 is a reusable dust extractor filter bag made for Festool CT 26 vacuums. This is a dust extractor filter bag designed for collecting large chips and non-hazardous debris before they reach the main filter. Model Number 496120. If you use a CT 26 for woodworking cleanup or general jobsite debris collection, this bag is built to reduce disposable bag waste and stretch the service life of your extractor's primary filter.

Where this bag matters is day-to-day operating cost. Festool states it can be filled and emptied up to 500 times before replacement, which is a big difference from a standard one-time-use filter bag. For shops and crews that regularly pull in planer chips, sawdust mixed with larger debris, or general cleanup waste, that reuse potential can add up fast. It is a practical choice for users who want to spend less time swapping bags and less money replacing them.

The construction is built around high-strength 3-layer polyester fleece. That matters because this is not just a thin liner inside the extractor. The material is intended for repeated emptying and reuse, while still trapping larger chips and debris before they load up the main filter. By catching that heavier material earlier, the bag helps extend the life of both the main filter and the dust extractor itself.

Festool also includes an integrated cap that forms a tight seal during bag removal and disposal. That is a simple feature, but it matters on the floor. When you pull the bag out of the extractor, the cap helps keep debris contained instead of dumping chips and dust back into the shop or the truck. For anyone trying to keep cleanup under control, that is one of those details you appreciate after the first full bag change.

This longlife filter bag is not a universal dust bag and it is not meant for every dust type. It is specifically recommended for large chips and debris, for class L dust, and for dust types that are not hazardous to health. It is not recommended for fine dust, and Festool specifically notes that it should not be used for RRP tasks. That makes the intended use pretty clear: this is the right accessory when your CT 26 is handling coarse material and routine extraction, not applications that call for fine dust capture or regulated hazardous dust handling.

If you already run a Festool CT 26 and want a reusable dust collection setup for larger debris, this bag makes a lot of sense. It is best suited to cabinet shops, trim carpenters, remodelers, and serious DIY users who generate bulk chips and want a cleaner, more cost-effective way to manage them. If your work leans heavily toward fine sanding dust or regulated containment work, stick with the bag and filter setup intended for that job instead.
