One of the easiest things you can do to create a healthy kitchen is to make use of the range hood vent. Ventilation can help remove air pollution from gas burners, fat particles from frying food and, of course, strong odors from whatever you’re cooking. To make the best use of your kitchen vents, try to cook on the back burners of your cooktop. This is where your vents are at their maximum performance. Don’t turn off the vents too early; keep them on until the pans you’re cooking with are cool to the touch.
