Replacement set with a washable two-layer fine dust filter and a washable emission (hygiene) filter designed to restore and maintain vacuum filtration. The fine dust filter captures larger debris from cyclonic cleaning and the emission filter retains very fine particles such as pollen and mold spores from expelled air. For best performance, wash the filters after every five dust-bin empties; replace the emission filter once per year and the fine dust filter every six months. Fits AEG QX6, QX7 and QX8. Dimensions: Width 85 mm; Depth 43 mm; Height 125 mm; Weight 50 g.
