To power your range hood, you need at least 100 CFM for every 10,000 BTUs of your stovetop. For example, a 100,000 BTU stove needs at least a 1000 CFM range hood. For electric stoves, multiply the stove width by 10. So, for a 42” electric stove you want a range hood with at least 420 CFM.

Why does a gas stove not need to be vented?

These pollutants include carbon monoxide, nitrogen dioxide, and formaldehyde. The study found that gas burners are often used without the support of a vented range hood and this greatly increases the risk of deadly gas buildup.

How many CFM for a range hood do I really need?

To meet the recommended CFM requirements, you'll need a range hood with 250 CFM. Island hoods – 150 CFM for every linear foot of cooktop.

What size hood do you need for a 30 range?

For example, for a 30” range, a 36” hood is ideal. Then, subtract 2” and you get 34”. So a 34” hood insert or larger is a great fit for a 30” range. For outdoor applications, go with an insert two sizes larger than your range.

How do you clean a ductless range hood?

Use a nylon or non-abrasive brush to remove grease, smoke deposits and build-up. Allow to sit for 3-5 minutes for the cleaner to penetrate tough buildup. Rinse filters with hot water and allow to air dry. Once dry, return filter to the range hood.

Do I need a downdraft on my gas cooktop?

Some stoves come with built-in downdraft vents that rise up from the back or center of the cooktop when a burner is lit. Like updraft hoods, downdraft units must be vented to the outdoors or they are ineffective. On a gas stove, a malfunctioning downdraft vent can allow dangerous carbon monoxide to remain in the air.
