Review on Fette Compatible AirClean Filter Complete by William Stevenson

I am increasing my rating from 5 stars to 2 stars. We have been using the new filter since 4/5/20 and in the last two weeks we have started smelling odors coming from the vacuum cleaner. It was odorless and lasted perfectly for about a month, which is why I originally gave it 5 stars. I've never had to switch Miele brands so often (probably 2 times a year). I'm going back to the Miele brand after I've used up the remaining 3 filters (unfortunately, my return period has already expired). At this rate I get Miele filters in 3 months.
