Do you need extractor fan with induction hob?
With induction hobs, they travel sideways as well as up, so you ‘ll need a hood that’s wider than your hob. For example, if you have a 60cm induction hob, choose a 90cm extractor. With gas, the steam has a candle effect that rises out then up. That means you can choose an extractor that’s the same width as your hob. Sep 8, 2017
