One of the key considerations when you buy a fan is how large your bathroom is in comparison with the amount of air the fan will move. It would not be sufficient to buy a fan that will take an hour to pull all the air out of the bathroom since by then the moisture or smells will have traveled into the rooms nearby. Measure the cubic area of your bathroom before you go shopping for an exhaust fan.
Instructions
1. Find out the square footage of the bathroom first. Measure the width of two perpendicular walls using a tape measure, using feet as the unit, not inches. Multiply the two measurements together to get the number of square feet included in the space of the floor. Include the bathtub/shower area in the wall measurements since you do want to include them in air removal.
2. Measure the height of the bathroom from the floor to the ceiling. Round the number up to the nearest whole number and then multiply it by the number of square feet in the room to get the total number of cubic feet.
3. Take the sum that represents the number of cubic feet in the room and round it up to the next whole number instead of a fraction to make sure you get a fan that is large enough.
