Range hood Buying Guide from Consumer Reports

Getting started

None of the over-the-range microwave ovens we tested could match the smoke-capturing ability of a good range hood. If removing smoke and fumes is more important to you than the convenience of a microwave, you're better off with a hood.

A fashion statement

Over-the-range hoods have become as stylish as they are practical. Most now offer the commercial look of stainless steel—and you needn't pay a pro-style price to get a pro-style hood. While you can spend about $1,000 for some models we tested, several delivered excellent overall performance for far less money. Many over-the-range microwave ovens also offer a stainless-steel finish.

How they performed

The best hoods we tested excelled at containing and exhausting smoke and fumes and exchanging air. Some were also notably quieter than the others and better at delivering high and low levels of lighting. Our tests of microwaves focused on cooking evenness, automatic defrosting ability, and ease of use. Subscribers can check our Ratings to see how the hood and microwave models performed.

Install it properly

Whether you opt for a hood or an over-the-range microwave oven, be sure it's installed according to the manufacturer's directions—typically, 18 to 30 inches above the burners or elements. That gives you working room while helping to prevent steam from escaping to the sides. Vent outdoors, if possible, using the largest-size solid, smooth-walled metal ducting that fits. Keep duct runs short and minimize bends to maximize airflow. A wall or roof cap outside the house prevents back drafts. Wash or replace the filters every one to three months—or more often if you cook frequently.

Types

The layout of your kitchen largely dictates the type of range hood you can use. To choose the right size range hood, be sure that any model you consider is at least as wide as the cooking surface it goes above. Here are the types of range hoods to consider.

Under-cabinet hoods

These mount under the bottom of a wall cabinet. Ductwork inside an adjoining wall, chase, soffit, or ceiling can exhaust smoke and fumes to the outside. In a few models, a shallow hood slides out of the upper kitchen cabinet when you need it. Typical kitchen cabinets extend only about halfway across the stove, so this extension routes steam and smoke away from cabinet faces and back toward the suction end of the range hood. This design steals cabinet space, but might be the only choice for those who cannot achieve the recommended stove-to-hood clearance with a standard under-cabinet-hood design.

Wall-chimney hoods

Wall-chimney hoods work where there are no cabinets over the range and mount with exposed vent stacks on the wall to vent to the outside.

Island hoods

Island hood These are mounted to and vented through ductwork in the ceiling. They lack a wall or cabinets alongside them to help funnel fumes.

Downdraft hood

These try to reverse the direction of rising smoke and fumes and exhaust them through ducts running beneath the floor. Our tests showed them to be among the least effective at removing smoke and steam. While they can be used anywhere in the kitchen, their main application is in islands where it might not be possible to route ductwork through the ceiling.

Ductless hoods

This is typically an option on some hoods, whether under-cabinet, wall or island. This type of installation directs steam, heat, and smoke away from the stovetop, but back into the kitchen. Its main filters can trap oil and grease droplets dispersed into the air above the range, and in most cases an optional carbon filter is available to reduce odors. We do not recommend a ductless hood, as it will take the smoke and odors being generated by the stove and disperse them throughout the kitchen and the rest of the home.

Features

Select a model at least as wide as the cooking surface underneath. (Island-mount hoods lack a wall or cabinets alongside them to help to funnel fumes, so they should be wider than the cooktop.) These are some range hood features to consider.

Airflow

Manufacturers tout the cubic feet per minute (cfm) of exhausted air. More airflow means faster ventilation, but it doesn't guarantee better smoke capture and removal in your kitchen. Many hoods that we tested that claimed to have modest airflow vented as well as those with twice the airflow.

Number of fan speeds

Most of the hoods we tested offer from three to six fan speeds. One model has a continuously variable speed. We recommend a minimum of two speeds: a high-speed setting to use when cooking and a very low and very quiet setting to use after cooking to continue to ventilate the space while eating. Any more than three set speeds are too many. If the manufacturer wants to provide more than three speeds, it should just use a variable speed switch that the user can easily set to any speed desired.

Thermostat control

A built-in temperature sensor in some models automatically turns on the fan if the temperature below the hood gets too high. This feature is available mainly on over-the-range microwaves. The real purpose of the thermostat is to protect the microwave electronics from being damaged by high temperatures. If the temperature under the microwave is too high, the exhaust fan comes on to draw away the hot air and pull in cooler air from the rest of the kitchen. But we do not recommend this feature on range-hoods because if you are cooking with oil and your pan catches fire, the exhaust fan will come on, drawing more air to the fire, fanning it, and perhaps making matters worse.

Exhaust timer

This convenient feature turns off the fan after a set period of time.

Brands

Range hoods come in four basic configurations, each designed for a specific application: under cabinet (vented and nonvented), wall chimney, downdraft, and island location. They range from 33- to 66-inch widths. Features to look for include high cubic-foot-per-minute capacity, electronic controls, auto start/speed heat sensor, food-warming capabilities, auto extend and retract, filter-maintenance indicators, and halogen lights. Use these profiles to compare range hoods by brand.

Broan

The biggest brands in the industry are owned by Notek and have about a 40 percent market share. They make range hoods in all configurations and types, with prices starting in the midrange. Nutone products tend to be lower priced while Best by Broan is the high-end line. You'll find them in Home Depot, Lowe's, Sears, and independent appliance stores.

GE

GE's Profile and Monogram range hoods cover the entire gamut of the category in terms of configuration, features, and price. GE range hoods are sold at Home Depot, Lowe's, Sears, and regional appliance stores.

Kenmore

The majority of the Kenmore's products are in the under-cabinet and wall-chimney configurations, with some downdraft models. Most models are in the low to midrange price categories; the Elite line features more-expensive models. You'll find Kenmore range hoods at Sears and Kmart stores.

NuTone

Vent-A-Hood

Vent-A-Hood sells products in the high end of the market, including 36- and 48-inch range hoods that match pro-style ranges.

Viking

Viking sells products in the high end of the market, including 36- and 48-inch range hoods that match pro-style ranges.

Whirlpool

Most Whirlpool range hoods come in under-cabinet and wall-chimney configurations, with a few models in the downdraft category. Whirlpool range hoods are low-to-midpriced and are sold at Lowe's, Sears, and independent appliance dealers.
