Choosing the right under-cabinet range hood for your kitchen can significantly impact both the efficiency and aesthetics of your cooking space. Whether you’re upgrading your kitchen or installing a range hood for the first time, understanding key factors such as size, CFM (Cubic Feet per Minute), noise level, and additional features is essential to making an informed decision.
What is an Under-Cabinet Vented Range Hood?
An under-cabinet vented range hood is a type of kitchen ventilation system that is installed beneath your kitchen cabinets, typically above your stove or cooktop. This vented range hood draws in the smoke, steam, and cooking odors from your cooking area and expels them outside of your home through a duct system.
Unlike ductless range hoods, which recirculate air back into the kitchen after filtering it, vented range hoods provide superior air quality by directing the air outside, ensuring that your kitchen stays fresh and clean.
Do Under-cabinet Range Hoods Need to Be Vented?
Under-cabinet range hoods typically offer two options: venting to the outside or using a carbon filter to recirculate the air. The choice depends on your cooking habits and frequency. If you cook with heavy oils or frequently, venting outside is the best option to ensure effective odor and grease removal. However, if your cooking is lighter, the ductless option with a carbon filter may work, but keep in mind that you'll need to replace the filter regularly.
How to Choose the Best Under-Cabinet Vented Range Hood
Selecting the best under-cabinet vented range hood involves considering several important factors to ensure you choose a model that fits your needs perfectly. Here are the key aspects to consider:
1. Size
Ensure the range hood is at least as wide as your cooktop or stove for optimal efficiency. A hood that is too small for your cooking area will not effectively capture smoke and odors. For example, a 30-inch cooktop (2.5 feet) requires a range hood that is at least 30 inches wide for the best coverage.
2. CFM (Cubic Feet per Minute)
CFM measures the airflow of the range hood. A general rule of thumb is to have 100 CFM per linear foot of your cooktop. For example, a 30-inch cooktop requires at least 250 CFM, but if you cook with oils, high heat, or strong-smelling food, opting for a higher CFM (400-950) will improve performance. A higher CFM ensures better suction and faster odor removal, especially in larger kitchens.
3. Noise Level
A quiet range hood enhances your cooking experience. Look for a model with a noise level below 60 decibels for comfortable kitchen use. If noise is a concern, consider range hoods designed with quieter motors, like the CIARRA Professional Series, which delivers powerful suction while maintaining a quieter operation.
4. Material
Choosing a range hood made from high-quality materials is essential for durability and long-lasting performance. 304 stainless steel is the gold standard for range hoods as it is corrosion-resistant and rust-resistant, making it ideal for high-moisture environments like kitchens. Stainless steel hoods maintain their sleek appearance over time, even with frequent use, and are easier to clean and maintain compared to other materials.
5. Additional Features
WiFi & App Control: Many modern range hoods, like the CIARRA Professional Series, now come with WiFi connectivity and the ability to control the hood through a mobile app or voice assistants like Alexa or Google Home. This smart functionality adds convenience, allowing you to control the range hood remotely, adjust fan speeds, or even set a timer.
Gas Leakage Detection: For added safety, look for models equipped with gas leakage sensors. These sensors can detect any unusual gas levels and send an alert, ensuring your safety while cooking. This feature is especially useful for homes that use gas stoves or cooktops, offering peace of mind in case of any leaks.
6. Budget
While high-end models offer advanced features like WiFi control and gas leakage detection, it’s important to balance performance with your budget. A more affordable range hood may offer the basic features like reliable CFM and noise control, but as you increase your budget, you can enjoy additional features such as smart controls, better filtration systems, and quieter operation. Always weigh the value of the features you need versus the price.
What is the Best CFM for an Under-cabinet Range Hood?
The best CFM (Cubic Feet per Minute) for an under-cabinet range hood depends on several factors, including the type of cooktop you have, the size of your kitchen, and the ductwork. Here’s how you can calculate the right CFM for your home:
1. Type of Cooktop
For electric cooktops, a general rule of thumb is to have 100 CFM for every linear foot of cooktop. For example, if your cooktop is 30 inches wide (2.5 feet), a range hood with at least 250 CFM is recommended. This will provide adequate airflow to remove smoke, steam, and odors effectively.
For gas cooktops, which generate more heat, you’ll need a higher CFM. Gas burners produce heat measured in BTUs (British Thermal Units). To determine the necessary CFM, add the BTU ratings for all the burners on your stove. For example, a standard four-burner stove with a total BTU rating of 40,000 would require a range hood with a minimum of 400 CFM. Divide the total BTU by 100 to calculate the CFM needed.
2. Room Size
The size of your kitchen or the room where the range hood is located is also important. A good rule of thumb is to choose a range hood that can exchange the air in your kitchen at least 15 times per hour. This ensures the air is kept fresh and free from contaminants.
For instance, if your kitchen is 20' x 20' x 10' (4,000 cubic feet), the required CFM can be calculated by dividing the room’s volume by 4 (since you want the air exchanged every 4 minutes). In this case, you’d need a 1,000 CFM range hood or higher to maintain optimal air quality.
3. Ductwork
The length and layout of your ductwork also affect the required CFM. The longer the ductwork, the harder it is for the fan to push air through, so you’ll need a more powerful motor. For every foot of ductwork, add one additional CFM. If your ductwork has elbow bends, add 25 CFM for each bend and 40 CFM for the cap.
