Hello,

Would you please tell me all about stove hoods.
I need a stove hood that is self-contained- is there
such a thing. In other words i can have no chimney
going out to the out side. the "hood" needs to be
directly over the stove; hugging the ceiling. Is there
such a thing?
Thank you.

There are, asMr. Meehan says, recirculating hoods.
They are better than nothing, and much less useful than vented hoods.
There are updraft and downdraft arrangements, if you need a path to the
outside.
