Central Hospital in Västerås – Problem with smell from sewers

Purchased an AC-D 30 of Oct. 2010. We are very satisfied and use it as a cleaner when smells arise here and there.
We first bought the unit because we had problems with the smell of a sewer in an adjoining room. The unit took away the smell in a week.
