This Haier I-Dual Series 6 induction hob shows cooking smells the door. It pulls vapours downwards and through a carbon filter before they drift across the room. All four zones run at 2000 Watts, and boost pushes any of them to 3700 Watts when you want a fast sear on lamb chops. Extraction peaks at 521m³/h while staying at a quiet 41dB. The glass-ceramic top wipes clean easily once you're done with dinner too. In automatic mode the hood reads the power level you've set on the hob and matches its own speed to it, so it works harder for a stir fry than for a light simmer.
