So that dust stays safely enclosed

Thus, the dust stays safely enclosed.
The Miele AirClean filter system consists of a genuine original Miele dustbag, a motor protection filter and one of the genuine original Miele exhaust filters. These three filtration levels ensure that the vacuumed up dust cannot escape. The room air is even cleaner after vacuuming than before and it takes longer for dust to settle again on furniture and surfaces.

Our recommendation for people with allergies
People with house dust allergies should look for a vacuum cleaner with a HEPA filter fitted as standard and specially sealed casing. These appliances guarantee that the air expelled from the vacuum cleaner is actually cleaner than usual indoor room air. Based on these characteristics, some Miele vacuum cleaners are specifically recommended for people with allergies by the TÜV Nord. In order for the appliance to maintain high filtration performance throughout its service life, the saturated, clogged HEPA filters must be replaced regularly - about once per year.
