Today many vacuum cleaners have filters positioned between the motor and the exhaust opening. This post-motor position is important for capturing fine particles that are generated by the vacuum cleaner’s motor. However, if air is not directed through the post-motor filter, the filter cannot be successful at capturing fine particles.
One can assert with absolute certainly that the Miele vacuum cleaner produces hundreds to thousand times fewer particles that the other vacuum cleaners tested.

Miele’s original Sealed System
Improperly sealed vacuum cleaners allow air to escape through various non-filtered openings. The Miele vacuum cleaner is completely sealed. Individual compartments and the system as a whole are all sealed with durable rubber. The sealed System protects against leakage and ensures proper air flow direction.
Filter names such as “HEPA-like” and “micro-filtration” can be misleading. To be called HEPA, a filter must prove 99.97% effective at capturing particles 0.3 microns and larger in a test environment. But even a true HEPA filter cannot succeed at capturing these particles if it is placed in a machine that leaks. Only Miele provides a true HEPA filter with post-motor positioning in conjunction with its Sealed System. This unique combination makes Miele the only vacuum cleaner capable of capturing practically all dangerous fine particles.
|Air enters through the floor nozzle and travels up the hose to the bag.|
|Air emitted from the bag moves through the filter and into the sealed motor chamber.|
|Air moves through the motor chamber toward the post-motor filter.|
|Air exits through the post-motor HEPA filter which traps fine particles.|
|Air released is almost totally free of particles 0.3 microns and larger.|
|The bag and motor compartments are sealed by rubber gaskets.|
|The unique rib system helps maintain powerful flow as air moves through the vacuum cleaner, even as the dustbag fills.|
