Main Filter for Pre-2019 Festool CT Mini and CT Midi (456790)

The Festool 456790 main filter fits older Festool CT Mini and CT Midi models manufactured before 2019. This is the standard main filter, designed to trap particles down to 1 micron, while maintaining good airflow. This lets you reach full capacity without clogging or caking. Proper filtration eliminates the majority of dust right at the source of emission, before it is ever released into the air, resulting in a cleaner, safer shop.
