Question: how much does it cost to run a bathroom exhaust fan?
Answer: Bathroom fans vary depending on the size of the motor and the speed settings. They come in different capacities and wattage ranging from 10W to 100W. For those powerful fans (let's say 60W to 100W units), the cost of operating such a bathroom fan may cost as much as 2.87c/h which converts to about $42 per year.
