The Basics of Kitchen Ventilation

Everything’s in place as you flex those culinary skills to impress guests with a cruciferous vegetable melange and seared trout. You flick the switch of the range hood, and nothing happens. It’s an odor catastrophe! Kitchen ventilation is a commonplace thing you take for granted until there’s an urgency to use it, and if it no longer works, you must replace it. Not only do range hoods and ventilators whisk away pungent odors, they swiftly evacuate moisture and grease and can help remove indoor pollutants.

When redesigning a kitchen, the goal is to determine specific cooking zones and install a hood or vent for most situations or needs, including wall mounts, under-cabinet, islands, or downdrafts. Some vent hoods use charcoal filters to trap moisture and odors while recycling the air. More sophisticated range hoods collect and vent excess moisture, cooking odors, airborne grease, and cooking-related smoke outside. This improves a home’s air quality while making the kitchen more comfortable.

With so many options in cooking appliances, it’s challenging to discern which ventilation units work best. As you define the scope of your kitchen project, you’ll realize that ventilation is a critical component and more important to your household members’ well-being than you initially thought. It’s in place to protect you and your indoor environment.

Most building codes require ventilation for stovetops and ranges. But what to choose? Under-cabinet or wall-mounted? Does an island need a dedicated vent? Shopping for kitchen ventilation shouldn’t be a total Wild West experience. To guide builders and consumers, the Certified Ratings Program (CRP) of the Home Ventilating Institute (HVI) tests and verifies residential ventilating products found on the HVI website. The U.S. Department of Energy includes its Energy Star-certified products on the Energy Star website.
