The SEBO X7/X8-series Service Box includes 8 AeraPure™ filter bags, a pre-motor microfilter, an exhaust filter, and a sealing strip. The electrostatically charged filter bags capture dust as the first stage of anti-allergy filtration. The pre-motor microfilter protects the motor by capturing fine dust, while the exhaust filter traps any remaining microscopic particles. Included with these, the sealing strip prevents debris kickback on hard floors.
