This SEBO Hospital-Grade Microfilter is for use in their C & K series canisters to keep them performing well. It is the fan-fold filter in a red frame located at the back of the vacuum.

Also available is the SEBO C Series Service Kit which contains eight white fabric bags and bag sealing disks plus the SEBO C Series Exhaust Microfilter and this Microfilter. SEBO recommends alternating between purchasing boxes of eight bags and purchasing the Service Kits so you can change the filters whenever you use sixteen bags.   For similar products see our list of SEBO Vacuum Supplies.
