Review on 🌬️ Miele Active AirClean 30 Filter: High-performance Air Filtration Solution by Troy Robinson

Every time I use a Miele cylinder vacuum there is a strange sour smell in the air. After reading various filter reviews, I realized that the smell was probably related to vacuuming dog hair, so I bought these filters even though they were significantly more expensive than normal non-carbon filters. When I first used this filter there was no smell at all which was great. But since then the foul smell has returned every time. My dog doesn't shed much so I don't know why the vacuum exhaust smells so bad. I should have just bought cheaper filters when the only way to get rid of the smell was to change the bag after every vacuum.
