I have the Ct 22 e. Which bag should I buy

Here are the various filter bag options available for your CT 22. We would recommend the fleece bags as the best disposable bag. The reusable bag is a good option for long-term use with the ability to empty and re-use it.https://www.festoolproducts.com/accessories/dust-extractors/bags.html?tn_festool_compatibility=CT+22
