A downdraft induction range is a cooktop that does not require a range vent hood placed above the unit. Downdraft induction ranges are assembled so the grease and smoke that develops during cooking is pulled by an exhaust fan into piping below the range that disperses outside of the home.
Downdraft induction ranges were designed to pull not only grease and smoke from the cook top, but also reduce the amount of pollutants in the air when cooking. The exhaust fan stored below the range or in a cabinet underneath the cook top is powerful enough to divert the pollutants, grease and smoke into the vent ducting. The vent continues to pull the air and pollutants through the vents and out of the house when the exhaust fan is turned on. Some downdraft induction ranges require users to turn on the system while some systems automatically switch on the exhaust fan when the range is lit or powered on.
Homeowners with small kitchens that do not have room for overhead ventilation find the downdraft induction range convenient and a space saver. A range hood, though, often works more efficiently to remove heat, fumes and grease because heat naturally rises. Lighting options may need to be installed manually with downdraft induction ranges because range hoods typically come with a light.
