Main Filter HEPA for CT MINI/MIDI - 496752 by Festool

HEPA main filter for use with the CT MINI or MIDI dust extractors (suits superseded CT MINI & MIDI models - not suitable for new CT MIDI-2 575839). The highest standard for filtration, HEPA filters capture 99.95% of all particulate matter down to .03 microns. HEPA filters (High Efficiency Particulate Air) have quickly become the new standard for wood dust collection, both in the workshop and on the jobsite. Measured in microns, wood dust is particularly troublesome to remove from an environment once it is airborne. Eliminate the majority of the dust created at the source before it is ever released into your environment. Designed to trap particles down to .03 microns while maintaining airflow, allowing you to reach full capacity without clogging or caking.
