Can you use bathroom fan in kitchen.

So if you have an 8 foot x 10 foot bathroom you would need at least an 80 cfm fan. A bath fan just won t cut it. An alternate approach is to use a ducted range hood or downdraft exhaust and a bathroom ventilation fan to exhaust the general odors and moisture in the kitchen. Have seen many bathroom fans used in kitchen over the years and all eventually fail in the same way in that oil grease in the air from cooking vapours etc build up on the fan blades and inside the fan casing causing the fan motor to sieze and stop working.

Bathroom and kitchen exhaust fans also can transmit large volumes of moist humid air into the attic or other confined spaces. As a general rule bathroom fans are not suitable for use in the kitchen as many have no filter inside them. The general rule is 1 cfm per square foot of space with standard 8 foot ceilings. You say the kitchen is 120 sf but you need to take in to account the height.

This can lead to wood rot mold and mildew. Depending on your usage you might consider a slightly larger fan to make sure you have enough power to clear the room. That would be 960 cf assuming 8 ft ceilings.
