By using the exhaust fans we create a negative air pressure in the home and therefore allow fresh outside air into the home.<br/><br/>I often work with energy star raters on houses we build and they typically say that 3500 to 4000 sf is the cut off between two approaches. For houses under that size it's appropriate to use exhaust fans to remove the moisture. Above that size home you should be using some type of heat recovery ventilation in order to exchange sufficient air.<br/><br/>If you can get sufficient air exchanges in combination with de-humidifiers then that would be ideal. So the long answer is it's more than just moisture. I agree and disagree with you.

I often work with energy star raters on houses we build and they typically say that 3500 to 4000 sf is the cut off between two approaches. For houses under that size it’s appropriate to use exhaust fans to remove the moisture. Above that size home you should be using some type of heat recovery ventilation in order to exchange sufficient air.

If you can get sufficient air exchanges in combination with de-humidifiers then that would be ideal. So the long answer is it’s more than just moisture.

Wouldn't it be better in these energy-saving times just to remove the extra moisture from the warm air, rather than exhausting both the moisture and the HEAT? Maybe I'm being too 'tight', but I hate the idea of sending warm air out through an exhaust fan, especially after I've spent so much time & money sealing all the leaks in my house (built 1996). What's wrong with just using a dehumidifier after showering, rather than an exhaust fan -- is it a huge electricity hog?
