Product review (1 stars): Poor instructions, needs an unknown attachment for ventless operation.
I was looking for a ventless range hood and ordered this. I had an installer come out to install it, and he told me it needed another piece. The Amazon.com entry doesn't say anything about another piece, so I researched as much as I could - the company has no website that I could find, so I just scoured Google - and the only other piece available was a filter assembly, which I also ordered. I had the installer come back and he told me it was still missing a piece. He couldn't tell me from looking at the directions what that piece was, and neither the manufacturer nor Amazon provides any helpful information. So this is going back. What a waste of time.
