Festool 498506 Longlife Filter Bag for CT 48 is a reusable dust extractor bag made for Festool CT 48 units. This is a longlife filter bag designed for large chips and debris collection in Festool CT 48 dust extractors. Model Number: 498506. If you are filling your extractor with bulkier waste and do not want to burn through disposable bags, this is the more economical setup.

What matters here is how it works in real use. Instead of treating the bag like a one-and-done consumable, Festool built this version to be emptied and reused up to 500 times. For shops and jobsites that generate a lot of larger chips, that can make a real difference in operating cost over time compared to standard disposable filter bags.

This bag is intended to trap larger chips and debris before they reach the main filter. That helps extend the life of both the main filter and the dust extractor itself. In plain terms, less big material gets where it should not, so the machine stays cleaner internally and maintenance stays more manageable.

Festool also uses a high-strength 3-layer polyester fleece construction for longer service life. That material choice matters because a reusable bag has to stand up to repeated fill-and-empty cycles without falling apart early. There is also an integrated cap that seals during bag removal and disposal, which helps keep debris contained instead of dropping back onto the floor when you pull the bag out.

This is not the right pick for every dust collection job. Festool states it is only for dust types that are not hazardous to health, is not recommended for fine dust, and should not be used for renovation, repair, and painting tasks. It is also identified for class L dust. That makes it a better fit for coarse waste collection than for finer sanding dust or more regulated cleanup work.

Compatibility is straightforward: this bag is suitable for the Festool CT 48 dust extractor. If that is your machine and your work produces larger chips and debris, this accessory makes sense. If your normal work leans toward fine dust collection, stick with the bag type Festool recommends for that application instead.

Who should buy it? Woodworkers, finish carpenters, cabinet installers, remodelers, and shop users running a CT 48 who mainly collect larger non-hazardous debris. If your goal is to save money over repeated use and reduce disposable bag waste, this is the practical choice. If you mostly collect fine dust, it is the wrong bag for the job, and that is worth knowing before you buy.
