Festool 454869 CT 22 & CT 33 Longlife Filter Elements, Set of 2 are specially designed to tackle the challenge of airborne wood dust, which can be difficult to remove once dispersed. These cloth-based Longlife Filter Elements feature a unique staggered "M" fold that effectively prevents dust build-up, ensuring optimal performance. The tough fabric construction enhances durability, especially when used with the scrubber handle, making the filters more wear resistant. Engineered to trap particles as small as 1 micron while maintaining excellent airflow, these filters allow your dust extractor to reach full capacity without clogging or caking. This set includes two Longlife Filter Elements, compatible with CT 22 and CT 33 dust extractors, providing efficient dust control at the source during woodworking and fabrication tasks.
