SEBO D4 Vacuum Series Filter Set
This filter set for the SEBO D4 canister vacuum cleaners includes both the pre-motor filter as well as the S-Class Microfilter. The Pre-Motor filter traps and dirt or larger particles that may have passed through the bag before they can reach the motor. The S-Class Exhaust Microfilter is the last stage of filtration in the SEBO D4 Airbelt. This Hospital grade filter traps 99.9% of all particles 0.3 microns or larger. Electrostatically charged, this filter cleans the air before releasing it back into your home. Replace both filters annually.
