Most of the IKEA Extractor hoods can be switched between recirculated and vented if your going with vented yes it’s just ducting but be warned you can only go to 2 meters without a secondary fan. Charcoal filters are optional and only needed if your recirculating.
The IKEA appliances are made by Whirlpool and Electrolux and have been designed for a common design theme so you can buy handles for the doors and drawers that match those on the appliances.
