The modern advances in bathroom fan technology have allowed for extremely quiet operation of today's Energy Star bathroom ventilation fan/lights. We have a number of Energy Star rated ventilation fan/lights that will suitably ventilate humidity and odor from your bathroom. 80 CFM (cubic feet per minute) fan/lights are ideal for 1/2 bathrooms, while fan/lights that are above 100 CFM will work well in an application where a shower or tub is present.
