Product review (4 stars): WORKS GREAT MAY NEED MAKE UP AIR DAMPNER.
One thing leads to another. This range hood does a great job of removing odors when ducted outside. Little to good now it sucks my pilot light out on my water heater. Will have to do something for make up air. I did buy some recirculating  filters to give that a try but that does not work nearly as good as good as venting it to the outside. Quality of range hood is not to bad other than paint being a little rough in spots.
