Miele stays airtight
"For people with house dust allergies, we recommend a vacuum cleaner with a HEPA filter fitted as standard." TÜV Nord has also recommended several Miele cylinder vacuum cleaners with HEPA AirClean filters for people with allergies. With the specialised casing seal the entire appliance, not just the exhaust filter, meets the requirements of the TÜV Nord, which are reviewed annually. The filtered and discharged air is cleaner than normal room air. In addition, bacteria, allergens and mould spores remain safely in the dustbag.
