Bissell 3304 filter for Vac & Steam 1977N, 1977E

Bissell 3304 — steam mop filter for the Vac & Steam 1977N, 1977E. In a machine that vacuums and steams at the same time the air filter lives in a damp environment: it clogs faster than a dry one and dries out more slowly. Washing it is fine, but it has to dry completely — a filter put back damp is the actual source of the smell people usually blame on the machine itself.
