Key Features
Made for CT 22These replacement filter bags are built specifically for the Festool CT 22 dust extractor, so fit and sealing are not a guessing game. That matters when you want clean bag changes and steady dust collection. Fine Dust ControlThe double-layer bag traps particles down to 5 microns while still maintaining airflow. You get cleaner operation without the bag choking off suction too early. Cleaner DisposalAn integrated plastic cap seals the opening during removal, helping keep dust in the bag instead of on the floor or back in the air. It is a small detail that makes shop cleanup a lot less messy.
Overview
Festool 452970 Replacement Filter Bags For CT 22 Dust Extractor, 5-Pack is a replacement filter bag set for Festool dust extraction systems. This is a replacement filter bag set designed for dry dust extraction in a Festool CT 22 dust extractor. Model Number: 452970. If you are still running a CT 22 and want clean bag changes, strong airflow, and less dust reaching the main filter, this is the right consumable for the job.
These bags work as the first stage of filtration inside the extractor. Festool rates them to trap particles down to 5 microns, which helps contain fine debris before it gets to the main filter. In practical terms, that means less internal contamination inside the vac, more consistent performance, and less time spent dealing with dusty filter maintenance.
Capacity matters on a dust extractor, and this bag is sized to hold up to 5.3 gallons of dust and debris. That gives you useful run time between bag changes for sanding, trimming, shop cleanup, and general jobsite dust collection. The bag is also designed to maintain airflow while filling, so you are not giving up capacity just to keep the machine breathing.
Festool uses a double-layer, tear-resistant paper construction with a plastic cap built into the inlet. That combination is what makes these bags more than just a disposable liner. The material is built to handle normal dry debris without splitting easily, and the cap lets you close the bag when it comes out. If you have ever pulled a dust bag and dumped a cloud back onto the floor, you already know why that cap matters.
These filter bags are intended for dry extraction only. They are made specifically for the CT 22 platform, so they are the right choice for owners of that extractor who want proper fit and normal Festool dust collection performance. They also help protect the main filter by keeping more debris out of it, which can extend the life of both the filter and the extractor itself.
This is a smart buy for woodworkers, remodelers, finish carpenters, installers, and anyone using a CT 22 for cleanup or connected tool dust collection. It is also the right pick for existing CT 22 owners who would rather use the correct bag than fight with poor-fitting substitutes. Simple product, but an important one: if the bag does its job well, your extractor stays cleaner, suction stays steadier, and disposal stays a lot less annoying.
Clean Changes, Less Dust Back in the Air
The big benefit here is not just dust collection. It is cleaner handling from install to removal. The built-in cap helps seal the bag when it is full, which keeps fine debris contained instead of spilling back into the shop or jobsite.
- Double-layer, tear-resistant construction for everyday dry dust collection
- Integrated plastic cap helps seal the bag during removal and disposal
- Acts as the primary filter stage to protect the extractor’s main filter

Pro Tip
If you are collecting a lot of fine sanding dust, change the bag before it is packed rock solid. These bags are designed to keep airflow up, but fine dust loads any extractor faster than bigger debris, so swapping a little earlier helps the CT 22 hold suction.
