How many CFM do I need for an exhaust fan?
The rule of thumb is that you need at least 1 CFM per square foot of room area. To determine the square footage of your bathroom, multiply the length times the width. For example, if your bathroom is 6 feet wide and 9 feet long, its square footage is 54. Therefore, it should have a fan rated for at least 54 CFM.Nov 22, 2021
Does exhaust fan make a difference?
When you buy an exhaust fan, you should ensure that it's installed as high as possible. ... Therefore, a fan will be more useful at the top than at the bottom. When it's installed high up, it will exhaust the hot air and improve the ventilation in a room. This will ensure that you get cooler air in all rooms of the house.Dec 30, 2014
