Choosing the right ventilator<\/a> for your range hood<\/a> starts with three things: your cooktop size, your cooking power, and how the hood will vent air. <\/p>\n\n\n\n

For most kitchens, you can estimate the airflow you need by using 100 CFM per 10,000 BTUs for a gas range<\/strong> or 100 CFM per 10 inches of cooktop width for electric and induction cooktops<\/strong>.<\/p>\n\n\n\n

After you know the right CFM, choose the blower style, ducting setup, and noise level that fit your kitchen. A well-matched ventilator helps remove smoke, grease, steam, heat, and cooking odors before they spread through your home.<\/p>\n\n\n\n

What Is a Range Hood Ventilator?<\/h2>\n\n\n\n

A range hood ventilator<\/a>, also called a blower, is the motorized part of the range hood that moves air. It pulls smoke, steam, grease, and odors away from your cooktop.<\/p>\n\n\n\n

Some blowers sit inside the hood. Others mount in the ductwork, on an outside wall, or on the roof. The right choice depends on your cooking style, your kitchen layout, and how much noise you want in the room.<\/p>\n\n\n\n

\n\n\n\n

Step 1: Match the Hood Width to Your Cooktop<\/h2>\n\n\n\n

Start with coverage. Your range hood should be at least as wide as your cooktop. This helps the hood catch rising smoke, steam, and grease before they spread across the kitchen.<\/p>\n\n\n\n

For many wall-mounted range hoods, matching the hood width to the cooktop width works well. For island hoods, wider coverage often helps because there are no walls or cabinets beside the hood to help contain rising air.<\/p>\n\n\n\n

A wider hood can be helpful if you:<\/p>\n\n\n\n
