The Miele AirClean filter system, consisting of the original Miele dustbag, the motor protection filter and one of the original Miele exhaust filters, ensures maximum hygiene. The amount of fine dust in the room air is significantly reduced: the interaction of all components guarantees a filtration of more than 99.9 % of fine dust^*. After vacuuming, the room air is even cleaner than it was before.
