The Best and Worst Types of Ventilation

Your new home is airtight, so whatever you cook stays in the house unless you vent it properly. The problem: most range hoods people buy can't actually do the job. In this video, we break down the best and worst types of kitchen ventilation, why most hoods fail on the one burner you use most, and what actually clears the air. Here's the rule everything comes back to: a hood only works if it covers where you cook. Most cooking happens on the front power burner, and most hoods are too shallow to reach it. Depth and a straight duct to the outside matter more than any brand name. 📘 FREE Ventilation Buying Guide: https://blog.yaleappliance.com/free-v... --------- THE BEST TYPES (what actually works) Wall and chimney hoods: Mounted against a wall, so the wall itself helps trap smoke and heat in the capture area. More stylish than the old American hoods, and the easiest way to vent well. Look for 23 inches of depth or more. Hood inserts: You take the guts of a hood and drop them into a custom wood or plaster enclosure. An inexpensive way to customize your kitchen. Same rule applies: the enclosure has to be built 23 to 24 inches deep, which is where most people get it wrong. Island hoods: The four-sided European style over an island cooktop. A beautiful focal point, but with no wall to help, you need to oversize the CFM. Always the right call over a downdraft on an island. Professional and commercial-style hoods: For high-BTU pro ranges. Plan on 27 inches of depth, 1,200 to 1,500 CFM, and often an external blower to move that much air. --------- THE WORST TYPES (what to avoid) Downdrafts: They fight physics. Heat and smoke rise, and a downdraft tries to pull them down through a narrow two-inch intake, into an elbow, and down a long duct that kills the airflow. It is the worst option for anyone who seriously cooks, and the newer telescoping and built-in versions do not change the math. If you have an existing downdraft, cook on the back burners and open a window until you can switch to a real hood. Over-the-range microwaves: They are only 15 to 16 inches deep, so they cannot cover a 22 to 23 inch cooking surface. The front burners sit completely uncovered. Newer flush models are just 12 and 3/4 inches deep, which takes a bad design and makes it worse. Ceiling blowers, slide-outs, and recirculating (ventless) hoods: Style over substance. They have little or no real capture area, and ventless hoods just push the air back into your kitchen. Use ventless only as a last resort when there is no way to duct outside. --------- THE BOTTOM LINE The best ventilation is simple: a hood against a wall, deep enough to cover your front burners (23 inches or more), ducted straight outside with no turns. That is exactly how commercial kitchens do it. Before you buy anything, ask one question: will this hood actually cover where I cook? --------- FREQUENTLY ASKED QUESTIONS What is the best type of kitchen ventilation? A wall-mounted hood (chimney, under-cabinet, or insert) at least 23 inches deep, ducted straight outside with no turns. The wall helps contain smoke and the depth covers your front burners. What is the worst type of range hood? Downdrafts. They work against physics with a tiny intake and a long, restrictive duct, so they can't keep up with a real cooktop. Over-the-range microwaves are a close second because they are far too shallow. Do over-the-range microwaves work for venting? Not for real cooking. At 15 to 16 inches deep they can't reach the front burners on a 23-inch cooktop, and their capture area and CFM are both small. How deep should a range hood be? At least 23 inches to cover the front burners where most cooking happens. Wolf goes 27 inches, the deepest available. Standard under-cabinet hoods are only 17 to 21 inches, which is why they underperform. Which blower is best: internal, in-line, or external? An external (roof) blower moves the most air, up to 1,500 CFM, but no one wants to fix a roof blower in a snowstorm. We prefer an internal blower because it is the easiest to service. In-line blowers need to stay accessible. Do I need make-up air? In MA and most areas, any hood over 400 CFM requires a make-up air system to replace the air it removes. Plan for it early. --------- LEARN MORE Learning Center (all our videos, articles, and buying guides): https://blog.yaleappliance.com/learni...
