Hello, we have a 6 X 8 X 8 bathroom. By the calculations we've made, it seems as though we should only need a 48-52 cfm bathroom fan. We bought a Broan Sensaire with a cfm of 120, because it can turn on and off based on moisture and motion sensors. Do you think 120 cfm may be too much?I am concerned about the possiblity of backdrafting and/or air pullling in from cracks in the house and/or the basement, leading to radon infiltration.

If this information should help: our home is 1947 (many air leaks); our furnace is closed combustion--we only have a water heater hooked up to the chimney; our stove is electric, not gas.

thanks much in advance--

I also installed a fan based on cfm and the size of the bathroom.The cfm have proved insufficient for whatever reason.I would recommend going with "as large as possible".As for the other concerns,I would say that since you are venting air out,it is better than breathing stagnant air.
