The Miele AirClean filter system filters more than 99.9% of all fine dust particles.
So you avoid contact with the dust, the vacuum cleaner bag closes automatically when the appliance is opened.
Thanks to several filter layers (fine) dust that has been vacuumed up cannot escape into the room air.
After vacuuming, the room air is even cleaner than it was before.
Thanks to the perfect key-lock principle, no dust can get past the Miele dustbag.
