I just moved mine to the middle of the bottom floor of a 2 storey home. It took some work and there is lots of fire safety code to adhere to but it wasn’t a difficult job if you can do basic jobs around the house. Mine was a 160mm circular steel vent which is typical here. With an external vent it’s also easy to put the fan on the roof or attic instead of in the hood, to reduce noise inside. An indoor-only hood with a charcoal filter is the alternative but only reduces odor. I couldn’t imagine not having an external vent from the kitchen. Super cheap but massive quality of life improvement.
