Vacuum Cleaners Discussions

Took my old Baird air flow meter to measure 3 Mieles:  The old Blue Moon with Vortex motor (a retrofit: Blue Moon originally had twin fan motors), a Miele Capricorn, and a Miele Uni-Q.

With same series clean bags and filters, the Blue moon pulled close to a 7 - 8, while the Uni-Q ad Capricorn pulled around a 6 - 7.

Interesting that oldest vac of the three moves the most air.

Ironically, the Blue Moon did best with its HEPA filter.  Using a Miele adaptor and Miele super clean filter dropped its airflow to a 6 - 7.  An odor removing filter performed the same as the super clean filter.
