How many CFMs does my bathroom fan need?

I was researching home ventilation recently (the very definition of ‘adulthood’, don’t you agree?) and came across this right-to-the-point video from the Home Ventilating Institute on how to properly size your bathroom exhaust fan. These experts also suggest how long you should leave the fan running after a “bathing event.” Oh and remember, me like adding a timer to the bathroom fan, if possible, so you don’t leave it on … for hours, accidentally.  Check out the short and handy video here. News you can use!
