Question

Where to keep an exhaust fan in the kitchen to expel hot air?

Answer 1

At the top of kitchan

Answer 2

  I prefer The overhead kitchen exhaust fans rather than the down-draft ones simply because hot air rises. It is even better to keep it near the window so that all the hot air directly goes out...   It is .a mechanical fan that sits above the cooktop in the kitchen. The fan's purpose is to remove grease that has become airborne, combustion products, smoke, odor and other fumes through the evacuation of the air combined with proper filtration. So it shd be the overhead kitchen exhaust fans..
