The X Series Service Box contains ten Ultra-Bags, an exhaust filter and a micro hygiene filter. SEBO Ultra-Bags utilise technology to give enhanced filtration, performance and hygiene. Electrostatically charged micro-fibres attract dust particles from the air stream and combine fade-free performance with highly effective micro-filtration. The included sealing caps ensure that unpleasant and potentially harmful particles are trapped in the bag for hygienic disposal, making SEBO Ultra-Bags ideal for allergy sufferers. Together with the filters, the Service Box offers high filtration.
