I saw the customer today. She had a standard fan, light combo for the main bath. She had a "ductless" fan for the other bath. It uses a charcoal filter in lieu of exhaust oultet. I think the filter may be good for a powder room, where no steam is generated, but the second bath has a shower also. Anyone familiar with this type of ductless fan?
It is a Broan model 682.
