How to Choose a Range Exhaust Hood in 2026?

Assess Your Cooking Habits and Ventilation Needs

A hood should match what happens over your cooktop, not just its width. Frequent searing, wok cooking, or frying sends more heat, grease, and fine particles into the room than occasional simmering. The U.S. Environmental Protection Agency identifies cooking as a source of indoor particulate pollution; gas combustion can also produce nitrogen dioxide. Think about your kitchen, too. A small, enclosed room may hold fumes longer than an open kitchen. That difference matters.

ASHRAE Standard 62.2 lists 100 cubic feet per minute (CFM) for intermittent kitchen exhaust, or 25 CFM for continuous exhaust. Treat that as a baseline, not a universal sizing rule: capture depends on hood depth, burner layout, and how close the hood sits to the cooktop. Check independently certified airflow and sound ratings through the Home Ventilating Institute. A powerful hood that you avoid using because it is too loud is not much help. I would leave some room for judgment; real cooking rarely follows a neat test setup.

Measure the cooking surface, not just the cabinet opening. Record the range’s width and depth, then note where its front burners sit. A 30-inch range needs a hood at least as wide; a wider hood can capture more escaping smoke. Check nearby cabinets, shelves, and trim before choosing the size. Small details matter.

Mark the range’s centerline on the wall or cabinet underside. The hood should sit directly above it, with enough depth to cover the front burners. Measure vertically from the cooktop to the hood’s underside. Required clearance varies by hood design and cooking surface, so follow the installation manual rather than relying on a generic number. Gas and electric setups may have different requirements. Check them carefully.

Also inspect the path for ductwork, if the hood vents outdoors. A short, direct route is generally easier to install than one with several bends. If the duct must pass through a cabinet, measure its interior space and look for shelves or wiring. I find it easy to focus on width and miss this. That mistake can change the whole plan.

Compare hood types before comparing airflow numbers. An under-cabinet hood suits a compact kitchen, while a wall-mounted chimney hood needs clear space above the range. Island models sit over an exposed cooktop, where cross-drafts can pull smoke away from the filters. Choose a hood that covers the full cooking surface; extra depth helps catch rising steam from front burners. Looks matter, but capture matters more.

Airflow is usually listed in cubic feet per minute, or CFM, but a larger number alone does not guarantee better ventilation. Match capacity to cooking heat, hood design, and duct conditions, following the hood maker’s sizing guidance and applicable local requirements. If you often sear food or use several burners, you may need more capture capacity. Also consider noise at the speeds you actually use; a loud hood may stay switched off. That trade-off is easy to miss. Before buying, check whether the duct can vent outdoors and whether the hood’s filters are accessible for regular cleaning.

Before choosing a hood, measure the cooktop and inspect the duct route. The Home Ventilating Institute’s sizing guidance uses about 100 cubic feet per minute per linear foot for wall-mounted hoods, and 150 for island hoods. Treat these as starting points, not guarantees. Lawrence Berkeley National Laboratory researchers found capture efficiency ranging from roughly 15% to 98% across tested residential exhaust devices. Hood shape, burner position, and airflow all mattered. Small details matter. A short, straight duct with the correct diameter usually works better than a powerful fan pushing air through several tight bends. Check the route.

Compare sound ratings in sones at the speed you will actually use. A quiet low setting is useful for simmering, but searing may need more airflow and create more noise. Check the published rating at each speed, not only the maximum setting. Look at motor wattage and lighting, too; lower settings generally draw less power, but real use depends on cooking habits. Before ordering, confirm cabinet width, mounting height, duct outlet location, and whether the wall or ceiling can support the unit. For gas cooking or a high-capacity hood, ask a qualified installer whether replacement air is needed. One easy-to-miss issue: a hood that fits the cabinet may still conflict with a joist, outlet, or duct bend. Measure twice.
