Miele HEPA AirClean SF-HA 50

CAVEAT: unlikely to be both HEPA and “Active” charcoal activated Take care with ordering these Miele SF-HA 50 Active HEPA filter for Models S4, S5, S6, & S8 – Genuine Miele Product. If you look carefully, you’ll see the product picture shows a different model code: “SF-AH 50” than what is in the title of this listing. The picture and title both claim the filter is both “Active” and HEPA. This means it should be a charcoal activated HEPA filter. But the filter I received was “SF-HA 50” which is a HEPA filter that is _not_ charcoal…

Bait & Switch don’t buy

This is a straight ISO standard HEPA filter, no carbon VOC stage This is a better filter than many people might tell you. The European ISO standards for air filtration have many different “grades” of filtration. This filter actually meets one of the intermediate standards. The base standard for HEPA certification is 99.7% of particles as small as 3 microns. This filter is better than that. It doesn’t meet the “Hyper-HEPA” standard of 99.7% of particles as small as 1 micron. It is somewhere in between those two. Bottom line? This is a VERY good HEPA filter…
