During a remodeling of my kitchen, I needed to replace the overhead stove fan w/light….are you getting the idea? I replaced the metallic filter with a home made filter from my furnace supplies (doubled up based on my exhaust), and routed the exhaust from the fan down a dryer tube to a small trash can. Had to add a ‘sink neck trap’ to slow the dust down, means clearing every so often, but being flexible it doesn’t pose much of a problem….Thoughts?
