AirClean Filter System, The Miele AirClean filter system, consisting of a genuine Miele dust bag, motor protection filter, and AirClean exhaust filter, ensures maximum hygiene. The amount of fine dust in room air is significantly reduced: The interaction of all the components guarantees the filtration of more than 99.9% of the fine dust. The discharged air is actually cleaner than normal room air with a HEPA AirClean filter.

Hygiene 3D Efficiency, Designed with optimum dust retention in mind, Miele has created the HyClean Dustbag with 3D efficiency. The bag side-folds ensure the whole of the bag is inflated when in use. This equates to an additional 20 percent more than the previous design.

Hygienic replacement, For hygienic replacement of the dustbag, The bag closes automatically when the appliance is opened to prevent dust from escaping when the bag is being replaced.

Bagged System, Miele has created a special fleece that provides nine layers of filtration that retain more fine dust and small particles than a conventional Dustbag. Also featured is the auto-shut mechanism that automatically closes the bag when the vacuum cleaner is opened, preventing dust from escaping back into the air.
