Maximum CFM for range hood without makeup air
In a tightly sealed house, what’s the maximum CFM that you could consider in a range hood without supplying makeup air. I know that the IRC allows up to 400cfm without makeup air, but is that actually advisable? Any personal experiences about 200-400cfm fans in tightly sealed houses?
I’m considering putting in a fan that goes up to 350cfm, and opening a window if I need to run it at full speed.
