How to confirm it's your model
Find the vacuum's rating plate: it's usually on the bottom or under the bag compartment lid. It shows the exact model. If it matches the Festool CT 26 or one of its variants (CTL 26 E, CTM 26, CTL 26 E AC, CTH 26), these bags will fit.
Tip: if you still have a used bag, check the cardboard collar. If it says 496187, you're on the right track.
How to change the bag on the Festool CT 26
- Unplug the vacuum and open the tank.
- Remove the used bag by its collar and seal it with the tab.
- Fit the new bag onto the intake until it clicks into place.
- Check the main filter and close the tank again.
How often should you change the bag?
In commercial use, daily or every few days. Change it at 3/4 full to avoid straining the motor.

What bag does the Festool CT 26 take?
The Festool CT 26 uses Festool SC FIS-CT 26/5 bags. The genuine part number is 496187 (also listed as SC FIS-CT 26/5). Compatible bags that list that part number or the model in the title also fit.
Do compatible bags work in the Festool CT 26?

In commercial use, daily or every few days. Change it at 3/4 full to avoid straining the motor.
Can I use the Festool CT 26 without a bag?
For dry debris, it's not recommended: the bag protects the main filter and the motor. Without it, the filter clogs quickly.
