A range hood (also called ventilation hood) provides ventilation for your kitchen. Range hoods are often taken for granted and underappreciated yet provide an essential role in maintaining the health of your home. An adequately ventilated kitchen improves the indoor air quality of your home and refreshes the air you breathe, both of which can be beneficial to the health of your family and the cleanliness of your home. A range hood ventilates the kitchen by removing excess cooking heat, moisture, steam, cooking odors, and airborne particles, such as cooking grease before they can deposit onto your kitchen cabinets, walls, drapery, carpet, or clothing. It can also help remove carbon monoxide from a gas cooktop and chemical vapors associated with household cleaning products.
What Are the Key Benefits of Range Hood Ventilation?
- Removes excess cooking heat, moisture, steam, vapors, odors, and airborne particles
- Reduces mold and bacteria build-up on countertops and cooking areas.
- Prevents cabinet damage by reducing grease build-up and condensation of acidic contaminants.
- Decreases mildew, peeling, and discoloration of wall finishes.
- Provides extra lighting over your cooking appliance and prep area, making it easier to see the details when cooking or cleaning.
- Enhances the look of your kitchen and adds to the resale value of your home.
- Gives you the freedom to cook what you want, without concerns about lingering cooking odors.
Range Hood Types
Range hoods come in a wide variety of styles, shapes, materials, colors, and finishes. The right range hood for your kitchen depends on many factors, including kitchen size and layout, cooktop location, kitchen cabinet configuration, budget preferences, and venting options available for your home. When selecting a range hood, the primary consideration is the venting options available for your home, which can significantly widen or limit your choice of range hood. The exhaust generated from a range hood must be vented somewhere—it will either go outside the kitchen or directed and dispersed throughout the kitchen.
Range Hood Styles
After you have determined what your venting options are for your kitchen, you are ready to choose from the many range hood styles available. As you compare range hood styles, you must consider the layout of your kitchen and cooking appliances, kitchen cabinet configuration, placement of the range hood, design preferences, and budget.
Undercabinet/Undercounter Range Hoods
The undercabinet range hood is the standard and most affordable style of range hoods. They are located directly above the cooktop and mount to the bottom of a wall cabinet, making them ideal for kitchens that lack space. In some space-saving models, a shallow range hood slides out of the upper kitchen cabinet when you need it. If the range hood is on an exterior wall, ductwork can be routed up through the cabinet and then outside, or for some models, directly through the back of the hood.Otherwise, ductwork must be routed through the cabinet to a chase, soffit or ceiling. Ductwork inside an adjoining wall, chase, soffit, or ceiling can exhaust smoke and fumes to the outside. Although ductwork for a vented range hood will likely reduce the amount of usable kitchen cabinet space, the benefits for venting outside far outweigh this loss.
Built-In Cabinet Range Hood/Cabinet Insert
A built-in cabinet range hood is hidden, designed to be built into the kitchen cabinetry above the cooktop for a custom approach to venting and designed to fit flush with the bottom of the cabinet. These range hoods are typically vented outside, but there are also some ductless recirculation models with charcoal or activated carbon filters available.
Wall Mount Hoods
Wall-mount range hoods work well in kitchens lacking cabinets over the cooktop or range. These exposed stacks typically take the form of chimneys or canopies and are mounted directly above the cooktop or range to catch cooking fumes, smoke, steam, or grease. Although most wall-mounted hoods are vented to the outside, some models can be used for ductless setup. Wall-mounted hoods can have internal or external blowers, ducted straight to the back, straight up, or up and horizontal. These range hoods help highlight the heart of your kitchen by making the stove or cooktop a focal point.
Island/Ceiling Mount Hoods
Island range hoods are designed for use over your island cooktop and are suspended from the ceiling over an island or peninsula. They can also be hung from peninsula wall cabinets. Island range hoods are finished on all sides and tend to be more expensive than other range hood styles. Some include telescoping chimneys to fit ceilings of varying heights. Since islands lack cabinets or walls to help direct cooking fumes up the vent, the canopy of an Island hood must be wider than the cooking surface to funnel the fumes. Island range hoods, like wall-mounted hoods, are striking and become a key focal point in the kitchen. They are growing in popularity with the growth of modular-style kitchens, where the cooking hub is in the center of the room.
Downdraft range hoods can be used anywhere in the kitchen. Their main application is in a kitchen island, where it might not be possible to route ductwork through the ceiling. They feature a unique space-saving design and are a perfect solution for kitchens with space limitations. They offer an unobstructed view and streamlined look in an open concept kitchen design where cooktops are frequently found in island and peninsula layouts. Available in a flush-mount configuration or in a pop-up design that retracts, removing the range hood from view when it is not in use. These range hoods draw air, smoke, and grease downward through vents, where the exhaust is expelled into ducts beneath the floor or into a basement and outside the home. Downdraft range hoods are considered less effective for ventilation as opposed to other vented range hood styles.
Custom Range Hoods
Customers who want to personalize the look of their range hood or match their range hood to their exact kitchen design specifications can order a custom range hood. Since they are customized, they are more expensive than other range hood styles. Custom range hoods include an external enclosure and an internal ventilation system.
Range Hood Inserts/Power Packs
Range hood inserts, also referred to as power packs, are the working ventilation “guts” of the hood that is placed within a custom range hood enclosure. These guts include the blower, filter, lights, and controls. Some of these units can also be customized to include optional features, like heat sensors or halogen lights.
Outdoor Range Hoods/BBQ Hood
Outdoor cooking has now become outdoor living. Many homes today have large, built-in outdoor kitchens replete with ranges, cooktops, grills, kitchen islands, walls, and furnishings. Cooking outdoors can generate intense heat and lots of smoke and grease and necessitate an outdoor range hood to clean the air. Outdoor range hoods are approved and rated for use outdoors. They can be mounted on a wall or hung over a kitchen island. Outdoor range hoods should extend the cooking surface by 3 inches on each side. For example, if you have a 36” grill, you need a 42” hood. The hood should also be deep enough to accommodate the deeper outdoor kitchen countertops, which are typically at least 30 inches deep (at least 6 inches deeper than indoor countertops).
OTR Microwave Hood Combination
Another appliance that helps ventilate the kitchen is the Over The Range (OTR) Microwave and range hood combination. Depending on the size and layout of the kitchen, the OTR is sometimes used in place of a range hood. It combines the ventilation function of an undercabinet range hood with that of a traditional microwave. Although OTRs provide some ventilation, they lack the strong ventilation ability of a true range hood.
Commercial Range Hoods
These range hoods can be found in restaurants and commercial food preparation companies around the world. You’ll be looking at large sizes, big CFMs, and professional-grade parts. Expect to pay a premium price for the product and installation. Keep in mind – to keep your resturant air quality high – and environment appealing, you’ll need an effective and as quite of the system as possible. For commercial, you will typically be best off working with a local HVAC company.
This type of range hood vents to the exterior of the home. It removes smoke, odors, and heat from inside the kitchen and forces it outside. A vented range hood is highly effective at eliminating cooking contaminants from the air. Although vented range hoods are highly effective at removing airborne cooking pollutants, they must be installed in an area with ductwork that goes from the inside of the kitchen to the outside of the home. This can limit the areas in the kitchen where you can position your cooking appliance and range hood. If ductwork is not already installed in your kitchen, the cost of installing a vented range hood can be cost-prohibitive.Installing ductwork is not an easy task for DIY and is best left to the professionals.
Non-Vented, Duct-Free/Ductless, Recirculated
This type of range hood installation is unvented. Instead of venting to the outside, cooking odors and airborne pollutants are directed and dispersed away from the cooktop and into the rest of the kitchen. Some models of ductless range hoods are fitted with replaceable filters made with activated carbon or charcoal, which helps to remove odor and smoke particles from the air before recirculating back throughout the kitchen.Many consider the ductless range hood to be less effective at cleaning the air than a vented range hood. Although less effective, a ductless range hood is not dependent on ductwork and can be placed anywhere in the kitchen. A non-vented unit is also much easier to install for DIY. Ductless range hoods are also more affordable than vented units.
Range Hood Selection Process
- Measure the width of your cooktop: the range hood must be at least the same width, or preferably several inches wider than your cooking appliance. Range hood widths range in size from 21 to 66 inches.
- Identify the location and layout of your cooking appliance; this will help determine the style of range hood you can choose (wall, island, or undercabinet styles).
- Determine where the exhaust from the hood will go. Do you have ductwork that will allow for a vented hood, or will you need a ductless hood?
- Determine your fuel source for your cooktop—is it gas or electric? Gas cooktops can produce carbon monoxide and require better ventilation than an electric cooktop.
- Consider your cooking habits and the types of foods you prepare. The more you cook, and the more frequently you use a cooktop to prepare your meals, especially for wok cooking or strongly seasoned foods, the better ventilation and a more powerful range hood you will need.
- Determine your budget preferences. Range hood prices vary depending on style, brand, model, and material, and can cost less than $100 to $5000 or more, not including installation.
- Determine your installation preferences—DIY or professional installation. Certain styles, such as Island range hoods, are much more difficult to install and may require the skills of a professional.
Airflow Strength / Range Hood Power
Measured in CFMs or cubic feet per minute (of the volume of air being exhausted through the range hood)
CFM ranges from under 100 to 1200 +
More airflow means faster ventilation, and in general, the higher the CFM, the better the airflow
The larger and more powerful your cooktop burners are, the more CFM is needed.
Rule of thumb, for electric cooktop: CFM is estimated by the size of the cooking surface. You need 100 CFM per every linear foot of cooking surface; Island Hoods require 150 CFM per linear foot to compensate for cross-drafts.
Rule of thumb, for a gas cooktop: for every 10,000 BTU your stove generates, you’ll need 100 CFM. Using this formula, a gas range with 40,000 BTU will require a range hood with at least 400 CFM.
Additionally, for every 3 inches a hood exceeds the suggested height above the cooktop, add 100 CFM.
Fan Loudness/Noise Levels
Noise levels associated with range hoods can vary greatly, depending on brand, model, CRM level, and fan speed. In general, the higher the CRM, the louder the noise. Personal preference determines what level of range hood noise is acceptable. Range hood noise is measured in sones. One sone (28 decibels) is equal to about the sound of a refrigerator hum, while normal conversations are at about 4 sones (48 decibels). Range hoods can generate anywhere from 2 to 8 sones.
Range hoods can have anywhere from 2 to 6 speeds. Some models offer variable fan speed control. Similar to a dimmer switch, variable speed control allows an infinite adjustment of fan speed based on preference.
Range Hood Filters/Grease Traps
Baffle: More common on high-CFM units, these slat-style metal filters force the smoke to change direction several times, causing grease droplets to separate from the air and drip down into a tray that can be taken out for cleaning.
Mesh: The hood’s blower pulls smoke and vapors through several layers of aluminum or stainless-steel mesh, catching the grease. These removable filters should be cleaned regularly—most can be popped into the dishwasher—to prevent clogs that can slow airflow.
Filter-less/centrifugal trap: Centrifugal force within the blower liquefies grease, which is collected in a tray or a cup that’s removable for cleaning. With no filters to slow the airflow, these hoods require fewer CFM than those with baffles or mesh to do the same job, often with less noise.
Activated Carbon or Charcoal Filters: these are disposable filters for ductless range hoods that must be replaced every few months to maintain their effectiveness at filtering the air of pollutants before recirculating back into the kitchen.
Range hoods provide additional lighting directly over the cooking surface to help illuminate the prep and cooking area. Different range hood models offer different lighting options, anywhere from 1 to 4+ lights.Lighting can be LED, Halogen, or Fluorescent. Some range hoods include low light settings, useful for night lighting. Others offer colored, ambient lighting, which can alter and enhance the look and mood of the kitchen.
Internal/Local: Refers to a blower that is built-in to the range hood body; this is usually the loudest type of blower. In-Line: This blower type is installed in the ventilation ducts between your hood and the outside vent. Typically, it’s installed in the attic or basement, making it easier to service. An in-line blower is quieter to operate than an internal blower since the fan is located farther away from the kitchen. This type of blower is beneficial with homes with long duct runs or several turns in the duct. External: Refers to a blower that rests on the outside of the home, either mounted on the roof or on an outside wall. Since external blowers are located some distance from the kitchen, they are typically the quietest option. This type of blower requires a more complex installation process.
Thermostat Control/Heat Sensor: By sensing temperature changes, some units will turn on the fan automatically or adjust to the appropriate speed if the temperature below the hood gets too high. Exhaust Timer: The fan can be preset to shut off at a specified time interval. Auto On/Off: Ability to preset fan on/off times. Food-Warming Capability. Auto Extend and Retract or Auto up and down: Some range hood units are retractable when not in use, and offer a remote-controlled or push button auto-extend and retract feature
Range hoods come in a variety of design styles to choose from, from traditional to modern. One of the most popular range hood styles is the “pro”style. These larger hoods have a commercial or professional chef vibe. Pro-style hoods are usually crafted from stainless steel and equipped with greater CFM power. Specifically designed to operate over higher BTU pro-style cooktops and grills. They are available in wall-mount, Island mount, or undercabinet mount.
Color, Finish and Materials
Range hoods come in a variety of finishes and colors. Popular metal finishes include brushed, polished, antique, and hammered metal. Trending colors include classic white and black as well as dramatic colors like red, blue, yellow, or turquoise. Special finishing touches, including metal rivets and straps, are also trending. Range hoods are made from a variety of materials, including stainless steel, copper, bronze, nickel silver, zinc, tempered glass, wood, aluminum, brass, heat-resistant plastics, and more.
How much does a range hood cost?
The price of a range hood varies greatly, depending on many factors, including exhaust type, mount style, brand, CFMs, options, and so on. The most affordable range hood type and style is the standard ductless undercabinet mount, with pricing starting at $100.00 or less. Wall-mounted and Island range hoods are more costly, with prices from $150.00 to $5000.00 or more. Copper range hoods are the most expensive, with prices between $500 to $30,000. Professional range hood installation can cost an additional $300 to $1000, with undercabinet or wall mounted ductless hoods the least expensive to install.
What is a Chimney Extension?
- Depending on the layout of your kitchen, a chimney extension may be required for your kitchen ceiling’s height.
- Extension needs will vary by ceiling height and hood type.
- If you have a particularly short or high ceiling, these extensions allow for a customized fit.
- Extensions can hide the ductwork that carries the air to the outside of your kitchen.
- The new homes of today are built to high standards of air “tightness” and often lack enough ventilation or exhaust ports.
- In certain municipalities, range hoods over 400 CFM may require “make-up air”.
- A make-up air unit enables fresh air to enter the home from outside when in use.
- A damper is required as an add-on to the range hood and helps replace the air when the hood is in use.
How to Use a Range Hood
A range hood must be in use to be effective at cleaning the air and ventilating your kitchen and should be used every time the cooktop is used. Yet, it’s interesting to note that according to a recent study, few people use their range hood on a regular basis. There are three main reasons why many don’t use their range hood. 1. Some people don’t understand the benefits of using the range hood 2. Some complain about the loud noise it generates when in use and 3. Others simply never think about using their range hood. A best practice in range hood use is to turn on the range hood 10-15 minutes prior to cooking; this will help establish proper airflow and improve the effectiveness of the hood to clean the air while cooking. Continue running the hood for an additional 10-15 minutes after cooking is completed to help remove any lingering odor, smoke, or grease from the kitchen. To quietly remove any lingering cooking odors, use a low fan speed. Higher fan speeds will help remove odors, heat, and steam when cooking on several burners at once.
How to Clean a Range Hood
Regular cleaning and maintenance of your range hood will ensure optimal performance. Apply a nonabrasive cleaner with a damp sponge and rub the area in the same direction as the stainless-steel grain. Use a stainless-steel cleaner and follow the manufacturer’s instructions. For enamel or powder coated color finish range hood Apply a nonabrasive cleaner with a damp sponge and rub gently until clean. Use a grease cleaner and follow the manufacturer’s instructions. Range hood grease filters can become blocked with grease if they’re not cleaned, limiting the hood’s ability to clean the air. Your cooking habits will determine how often you need to clean the filters; more frequent cooking means more frequent cleaning. Experts recommend cleaning the filters after every 30 hours of use (about every month or two) to keep a hood running smoothly.Most vent hood filters can be placed in a dishwasher and cleaned on a low heat or short cycle settings. Some filters may become discolored when using dishwasher detergent with phosphates. Vent hood filters can also be washed by hand, using warm water, liquid dishwashing detergent, and baking soda. Soak the filter for 1 to 2 hours and then rinse. Allow the filter to dry completely before reinstalling.
Since the early development of humanity, people have been cooking food with fire. From open flame fire pits to the development of brick and stone ovens, people have turned to natural and later, mechanical means to ventilate the smoke and fumes from cooking. By 1880, technological innovation in the stove led to the development of a fuel-driven heater fan. Outdoor air was drawn into the bottom of the oven and released as heated fresh air into the stovetop. Gas fumes were taken out of the chimney, which created a vacuum that drew out the room air. The warmth of the stove ran thus both supply and exhaust air.
Since the early 1900s, many inventors have helped develop the modern range hood into what it is today
In 1926, Theodore R.N. Gerdes applied for a patent for “ventilating hood for ranges” which used a fan to capture escaping fumes.
Two years later in 1928, Lloyd W. Ray developed a ventilation system that separated grease from vapors, pulled heat from under the stove, and helped clean the air.
In 1932, Henry Broan developed and manufactured a kitchen fan called the Motordor Fan that provided quiet and efficient kitchen ventilation.
Then in 1933, Dallas based Vent-A-Hood Company became the first manufacturer of residential range hoods in the USA.
The 1950s and ‘60s saw further development of range hood technology. James A Nelson and Frederick J. Port devised a way to cool the sides and top portions of a range, and William A. Pledger filed several range hood-related patents, including a detachable and replaceable filter “to collect the grease from fumes and smoke drawn off from said ranges.”
In 1967, Donald E. King filed a patent for his kitchen exhaust hood with a “drip-proof louver for receiving hot grease-laden air, water spray to cool the hot air and condense the grease and a blower for discharging air drawn into the hood and centrifugally separating water droplets therefrom.”
Innovations in range hood technology, materials, and design continue today.
For example, in 2017, Robert Siegel (associated with ProLine brand of range hoods) with the help of other inventors, developed new features in range hood automation, including a patented range hood that monitors and responds to changes in air quality during use and includes an alarm with motion detector that adjusts the alarm volume as needed.
Today’s Leading Brands
Over 100 companies that manufacture and distribute range hoods across the globe today. One of the largest manufacturers is Broan-Nutone LLC (that include Broan, Nutone, and Best range hood brands), whose parent company Nortek owns 40% of the market share in range hoods. Range hoods are sold under dozens of brand names. A few prominent brands include Broan, Elica, Faber, CopperSmith, Samsung, Whirlpool, Wolf, Viking, and Zephyr. High-end range hood brands are mainly from Germany, Italy, and the USA, and include Gaggenau, Miele, Bertazzoni, Elica, Faber, Futuro Futuro, ProLine, and Zephyr.
Innovations in Range Hood Technology
Many of the innovations in range hood technology today relate to the advancement of electronic functions and the integration of smart home technology/ IoT. Some range hood brands offer models with electronic controls and WiFi or Bluetooth capability (e.g., Bosch and Samsung). Air quality sensors and alarms are also becoming more popular (e.g., ProLine)LED lights and dimmable and colored lights (e.g., Zephyr), Noise reduction technologies (e.g., Vent-A-Hood)
3 Well-known Range Hood Brands

Tips and Advice
Before doing anything, shut the power off at the breaker box. Follow the installation instructions according to the range hood manual. For optimal performance, install a hood between 20 and 24 inches away from an electric cooktop and 24 to 30 inches from a gas cooktop. The higher your range hood is from the cooktop, the less effective it will be, so it is important to compensate for extra height by increasing the CFM and/or coverage (width and depth).
How to Replace Your Old Range Hood
You’ll need your new range and a few tools: a drill, Phillips and flat head screwdrivers, and an a/c detector. Double-check that the power is off, checking with the a/c voltage detector that the wires are not live. Unplug the old hood and disconnect the electrical range wires from the home wiring. Have someone help you lift aside the old hood and remove the support screws that hold the unit to the wall or cabinet. Looking at your new range hood, identify the correct opening for your vent, e.g. rear duct opening, matching up your new vent hood with the same vent opening location for the wires and exhaust. Attach the new range hood into the old location, connecting the wiring as stated in the new range hood manual. Turn on the electricity at the breaker box to verify that the new installation is working properly.
