Good air quality is important - and not just for allergy sufferers. The HEPA filter absorbs 99.95% of fine dust particles, bacteria and pollutants from the ambient air and ensures particularly clean air is blown out. The filter is also washable and saves on follow-up costs. Quiet vacuuming with extremely thorough cleaning performance is possible at all times thanks to activeSound Control. The entire appliance concept - from the nozzle to the exhaust air - has been optimised to ensure low noise levels.
