DIRTY LITTLE SECRET ... REVEALED

Interbasic Resources (IBR), an accredited third party laboratory undertaking the testing of particulate contamination and filtration performance verification, was commissioned by Miele to conduct an efficiency test of five leading vacuum cleaner brands to assess their respective emissions' rates.

One test was conducted to determine the volume of carbon dust particles emitted from each vacuum cleaner's fan. The ensuing test results were alarming with the poorest performing unit discharging over 13 million particles (0.3-0.5 micron in size) per minute. These sized emissions constitute the very particulate matter that the EPA warns, and regulates, against.

Miele captured motor emissions most effectively, emitting 638 times fewer carbon dust particles than the average vacuum cleaner tested.
