Review on Miele Vacuum Cleaner SF HA30 MIE1003 by Melissa Wilson

The first of these HEPA filters I bought for my Miele vacuum gave a clear indication of when it needed replacing. Neither of the next two (this is my third) did. I was seriously wondering if I had the right filter, especially since the grille that goes over it doesn't close completely with the filter in place. But I looked it up in my manual and it's the right filter.
