Festool CT Mini and Midi filter bags, six to a box
When the dust bag in your CT Mini or Midi fills up, suction drops and cleanup gets messy. These non-woven replacement bags drop into the vacuum and keep it pulling full power.
They capture class L and M dust and hold it. A self-locking auto-seal collar closes the bag as you remove it, so the dust you just collected doesn’t end up back in the air. The collapsible bag shape clears the dust cake between cycles, which keeps suction strong and the bag lasting longer.
