Understanding CFM: Choosing the Right Range Hood for Effective Kitchen Ventilation

What are Range Hoods For?

A range hood works by eliminating airborne grease, combustion products, odors, and steam generated during cooking.
It helps reduce indoor pollution and creates a safer, more comfortable space for cooking and dining.
A range hood provides a dash of style to your kitchen and does some heavy lifting.
Removal of Grease Means Less Cleanup - Without proper kitchen ventilation, airborne grease from cooking can settle on surfaces, forming a difficult-to-clean film.
Ducted Range Hoods Remove Heat - Ducted hoods also remove excess heat from cooking, released thermal energy otherwise stays concentrated, causing discomfort, material deterioration over time, and increased AC usage.
Multipurpose (Overhead Lighting) - Many hoods have integrated halogen or LED lighting, providing extra brightness ideal for ambiance or small tasks.

Under the Cabinet Range Hood - a classic choice for kitchens with a focus on space optimization.
Wall Mounted Range Hood - for kitchens without upper cabinets or those embracing a contemporary aesthetic.
Island Range Hood - designed to work seamlessly with island cooktops.
Insert Range Hood - designed for seamless integration into custom cabinetry.
Downdraft Range Hood - built directly into the cooktop, pulling steam and fumes downwards and away.
Microwave Hood Combinations - combines ventilation function with traditional microwave.
Range Hood Liners - working ventilation “guts” of the hood.
Retractable Downdraft Hoods - provide a sleek, integrated ventilation solution by remaining flush with the countertop until needed.
Ducted Range Hoods - vents to the exterior of the home.
Ductless Range Hoods - unvented range hood installation.
Convertible Range Hoods - can be configured for either outdoor circulation or indoor recirculation.

By Power: Understanding CFM Ratings - When shopping for range hoods, you’ll find yourself asking one major question: What are CFMs?
How Much Kitchen Ventilation Do I Need? - A proper kitchen ventilation system will effectively remove or condition all the air in a kitchen at least four times an hour.
By Room Size - With that in mind, you can determine how many CFMs you need for your space by dividing its dimensions (in square feet) by four.
By Cooking Appliance - The type of cooking appliance also impacts the required types of range hoods.

Measuring for a Range Hood - Proper measurement is key before selecting a range hood.
Range Hood Styles - Popular hood configuration styles include:
Hood Features - When choosing a high-quality range hood, there are key functional considerations beyond just looks.
Size and Fit - Ensure the hood is wide enough for your range.
Venting Strength (CFMs) - The CFM rating of the range hood determines how effectively the unit can ventilate your kitchen.
Heat Compatibility (BTU Ratings) - The type of cooking appliance also impacts the required types of range hoods.
Fan Loudness/Noise Levels - Noise levels associated with range hoods can vary greatly.
Fan Speeds - Range hoods can have anywhere from 2 to 6 speeds.
Range Hood Filters/Grease Traps - Baffle, mesh, filter-less/centrifugal trap, and activated carbon or charcoal filters.
Lighting - Range hoods provide additional lighting directly over the cooking surface.
Blowers - Internal, in-line, and external blowers.

Color, Finish and Materials - Range hoods come in a variety of design styles.
Ceiling Height - Most range hoods are designed for kitchens with standard ceiling height.
Materials - Explore different materials for your range hood.
Location - Consider the location of your stove when choosing a range hood.
Function - Think about how you use your kitchen when buying a range hood.
Indoor or outdoor - Range hoods are designed for indoor and outdoor kitchens.

Is 65 dB loud for a range hood? - 65dB is considered loud for a range hood, but not necessarily unbearable.
What is the best CFM for a range hood? - Look for a minimum 100 CFM of airflow for every 12 inches of stovetop width.
What is the best height for a range hood? - Range hoods come in different sizes, depending on the size and shape of the kitchen.
