The Festool 456737 Longlife Reusable Filter Bag For CT 22 Dust Extractor is a reusable dust extractor filter bag made for Festool CT 22 vacuums. This is a filter bag designed for collecting larger wood chips and non-hazardous dust during dust extraction. Model Number 456737. It makes the most sense for woodworkers, trim carpenters, cabinet installers, and remodelers who use routers, planers, or other tools that generate a lot of shavings and are tired of burning through disposable bags.

Where this bag earns its keep is in high-volume chip collection. Festool states it can be reused up to 500 times, which matters when a standard paper bag would fill quickly with bulky debris. If your work creates curls, chips, and larger particles instead of ultra-fine sanding dust, a reusable setup like this saves time on bag changes and lowers ongoing consumable cost.

The bag uses a non-stick micropore plastic lining and a high-strength 3-layer polyester fleece construction. In plain terms, that means it is built for repeated emptying and reuse rather than being treated like a disposable accessory. The integrated cap is another practical detail: when you pull the bag out for disposal, the cap helps seal the opening so dust and chips stay in the bag instead of ending up back on the floor or in the truck.

This accessory is also doing more than just holding debris. By trapping larger particles before they reach the extractor's main filter, it helps reduce the load on the rest of the system. That can help maintain cleaner operation and reduce how often the main filter has to deal with heavy chip buildup.

There is an important limitation, and it is worth being direct about it. Festool does not recommend this bag for fine dust created by sanding. It is intended for class L dust and for dust types that are not hazardous to health. So if your main use is sanding drywall compound or fine finish sanding dust, this is probably not the right bag for that job.

Who should buy it? The right buyer is the CT 22 owner who regularly collects shavings from routing, planing, and similar woodworking tasks. If you are mostly doing fine-dust work, stick with the proper disposable bag option. If you are filling bags with chips all day, this reusable Festool accessory is the smarter setup.
