A rangehood, also known as a kitchen exhaust fan or cooker hood, is an essential appliance in any modern kitchen. Its primary purpose is to remove smoke, grease, odors, heat, and steam generated during cooking, thus improving air quality and preventing grease buildup on surfaces. Choosing the right rangehood can be a daunting task, given the myriad of options available. This guide aims to demystify the world of rangehoods by exploring the different types, their functionalities, and suitability for various kitchen setups.
Understanding the Basics of Rangehood Functionality
Before diving into the different types of rangehoods, it’s crucial to understand how they work. Most rangehoods operate on one of two primary principles: ducted ventilation or recirculating ventilation.
Ducted rangehoods, also called vented rangehoods, are connected to a duct that leads outside the home. They draw the contaminated air through the filters and exhaust it outdoors, effectively removing smoke, grease, and odors from the kitchen. This is generally considered the most effective method of ventilation.
Recirculating rangehoods, also known as ductless rangehoods, filter the air through charcoal filters to remove odors and grease. The cleaned air is then recirculated back into the kitchen. While they are easier to install as they don’t require ductwork, they are less effective at removing humidity and heat compared to ducted models. Charcoal filters need to be replaced regularly, adding to the maintenance cost.
Exploring the Various Types of Rangehoods
The type of rangehood you choose will depend on your kitchen layout, cooking style, and budget. Here’s a comprehensive overview of the most common types of rangehoods available:
Under-Cabinet Rangehoods

These rangehoods are generally compact and space-saving, making them ideal for smaller kitchens or kitchens with limited cabinet space. They can be either ducted or ductless, offering flexibility in installation.
The performance of under-cabinet rangehoods can vary depending on the model. Some models offer sufficient ventilation for light to medium cooking, while others may struggle to effectively remove smoke and odors during heavy cooking. Look for models with higher CFM (cubic feet per minute) ratings for better performance. Pay close attention to the noise level as some under-cabinet models can be quite noisy at higher speeds.
Wall-Mounted Rangehoods
Wall-mounted rangehoods, also known as chimney rangehoods, are designed to be mounted directly on the wall above the cooktop. They are a popular choice for kitchens without upper cabinets above the stove.
These rangehoods often feature a sleek and stylish design, making them a focal point in the kitchen. They are typically ducted, providing excellent ventilation and effectively removing smoke, grease, and odors.
Wall-mounted rangehoods come in a variety of styles, including traditional chimney shapes and more modern, minimalist designs. The height of the chimney can often be adjusted to suit different ceiling heights. Ensure the rangehood is properly sized for your cooktop; it should be at least as wide as the cooktop and ideally a few inches wider.
Island Rangehoods
Island rangehoods are specifically designed for kitchens with island cooktops. They are suspended from the ceiling above the island, providing ventilation from all sides.
These rangehoods are typically more powerful and stylish than other types of rangehoods, as they need to effectively ventilate a larger open space. They are almost always ducted, requiring careful planning for ductwork installation in the ceiling.
Island rangehoods are available in a variety of shapes and sizes, including rectangular, cylindrical, and curved designs. Consider the overall aesthetic of your kitchen when choosing an island rangehood, as it will be a prominent feature.
Downdraft Rangehoods
Downdraft rangehoods are integrated into the cooktop or installed behind it. They work by drawing air downwards, away from the cooktop, and venting it through a duct located under the floor.
These rangehoods are a good option for kitchens where a traditional overhead rangehood is not feasible or desired, such as in open-concept kitchens or kitchens with limited upper cabinet space.
Downdraft rangehoods are generally less effective than overhead rangehoods, as they have to work against the natural rising of hot air and smoke. However, modern downdraft models have improved significantly in performance. Carefully consider the placement and power of the downdraft rangehood to ensure adequate ventilation.
Professional Rangehoods
Professional rangehoods, also called commercial-style rangehoods, are designed for serious home cooks and those who frequently engage in high-heat cooking. They are typically larger, more powerful, and more durable than standard rangehoods.
These rangehoods often feature high CFM ratings, powerful motors, and robust construction to handle the demands of professional-style cooking. They are usually made of stainless steel and have a sleek, industrial look.
Professional rangehoods are almost always ducted and require professional installation. Be prepared to invest in a powerful and potentially noisy rangehood if you opt for a professional model. Consider the noise level and whether it is acceptable for your kitchen environment.
Convertible Rangehoods
Convertible rangehoods offer flexibility in installation, as they can be configured for either ducted or ductless operation. This makes them a versatile option for kitchens with varying ventilation needs.
These rangehoods typically come with a ducted adapter and charcoal filters for ductless operation. The charcoal filters need to be replaced regularly.
Convertible rangehoods are a good choice for renters or homeowners who may want to switch between ducted and ductless ventilation in the future. Ensure the rangehood is properly installed according to the manufacturer’s instructions for the chosen ventilation method.
Custom Rangehoods

What is the main difference between ducted and ductless (recirculating) rangehoods?
The primary difference lies in how they handle cooking fumes and odors. Ducted rangehoods vent air outside the home through ductwork. This process effectively removes smoke, grease, heat, and smells from the kitchen, providing a cleaner and healthier air quality. They are generally considered more efficient at removing pollutants as they completely expel them from the kitchen environment.
Ductless rangehoods, on the other hand, filter the air through charcoal filters to remove odors and grease before recirculating it back into the kitchen. These rangehoods do not require ductwork, making them easier to install. However, they are less effective at removing heat and humidity, and the filters require regular replacement to maintain optimal performance. They are a suitable option when ducting to the exterior is not possible or practical.
What are the advantages of using an under-cabinet rangehood?
Under-cabinet rangehoods are a popular choice due to their space-saving design and ease of installation. They fit neatly under existing kitchen cabinets, maximizing space and integrating seamlessly into the kitchen layout. They are typically more affordable than other types of rangehoods, making them a budget-friendly option for homeowners seeking basic ventilation.
Another advantage is their relatively straightforward installation process. Often, they can be installed without requiring significant modifications to existing cabinetry or ductwork (in the case of ducted models). Under-cabinet rangehoods also come in both ducted and ductless configurations, providing flexibility depending on the kitchen’s layout and ventilation needs. Their compact size makes them a good choice for smaller kitchens or apartments.
What is a chimney rangehood and what kitchen styles does it suit best?
A chimney rangehood, also known as a wall-mounted rangehood, is a visually prominent type of rangehood that mounts directly on the wall above the cooktop. Characterized by its distinctive chimney-like structure extending upwards, it adds a focal point to the kitchen. It’s available in a variety of materials like stainless steel and glass, allowing for design flexibility. These rangehoods are generally more powerful than under-cabinet models.
Chimney rangehoods complement a wide range of kitchen styles, particularly contemporary, modern, and transitional designs. Their sleek lines and modern aesthetics make them a fitting choice for kitchens with clean, minimalist designs. They can also blend well in more traditional kitchens depending on the specific design and materials. The aesthetic versatility of a chimney rangehood allows it to be integrated into diverse kitchen aesthetics.
What is a downdraft rangehood and when is it most appropriate to use?
A downdraft rangehood is a type of ventilation system that is integrated into the cooktop or installed behind it, pulling air downwards instead of upwards. It works by drawing smoke, steam, and odors away from the cooking surface and venting them either to the outside or recirculating them through a filter. Downdraft rangehoods offer a sleek and unobtrusive alternative to traditional overhead rangehoods.
Downdraft rangehoods are most appropriate in kitchens where an overhead rangehood is not feasible or desirable due to design constraints. This could include situations where there are no upper cabinets above the cooktop, or when the homeowner prefers a clean and minimalist look. Island cooktops often benefit from downdraft systems as they avoid obstructing the view. Their low profile design helps maintain an open and airy feel in the kitchen.
What are the key factors to consider when choosing a rangehood for a gas cooktop versus an electric cooktop?
When choosing a rangehood for a gas cooktop, it’s crucial to consider that gas cooktops typically produce more heat, smoke, and combustion byproducts than electric cooktops. Therefore, a more powerful rangehood with a higher CFM (cubic feet per minute) rating is generally recommended. A ducted rangehood is also preferred to effectively vent these pollutants outside the home. Proper capture area is also important to contain the fumes effectively.
For electric cooktops, while heat and smoke are still produced, the level is often less than with gas cooktops. Therefore, a rangehood with a slightly lower CFM rating may suffice. While a ducted rangehood is still beneficial, a ductless rangehood can be a viable option, especially if ducting is difficult. However, regular filter maintenance remains essential. The key consideration is to select a rangehood that adequately addresses the specific ventilation needs of the chosen cooktop type.
What is a rangehood’s CFM rating, and why is it important?
CFM, or cubic feet per minute, is a measurement of the volume of air that a rangehood can move in one minute. This rating indicates the rangehood’s ability to effectively remove smoke, grease, odors, and other airborne particles from the kitchen. A higher CFM rating means the rangehood can ventilate a larger area and handle more intense cooking fumes.
The CFM rating is important because it directly impacts the rangehood’s effectiveness. Choosing the right CFM depends on several factors, including the size of the kitchen, the type of cooktop, and the frequency and intensity of cooking. Insufficient CFM can result in lingering odors, grease buildup, and poor air quality, while excessive CFM can lead to energy waste and unnecessary noise. Calculating the appropriate CFM for your kitchen is a crucial step in selecting the right rangehood.
How often should rangehood filters be cleaned or replaced?
The frequency of cleaning or replacing rangehood filters depends on several factors, including the type of filter, the frequency of cooking, and the types of food being cooked. Generally, metal grease filters should be cleaned every 1-3 months to maintain optimal performance and prevent grease buildup. They can typically be washed in a dishwasher or by hand with hot, soapy water.
Charcoal filters, used in ductless rangehoods, require more frequent replacement, typically every 3-6 months, depending on usage. These filters cannot be cleaned and must be replaced to effectively remove odors. Regular cleaning or replacement of filters is essential for maintaining proper ventilation, preventing fire hazards, and ensuring the longevity of the rangehood. Neglecting filter maintenance can significantly reduce the rangehood’s efficiency and potentially damage the unit.
