What CFM capacity bathroom fan do I buy?

Start your quest for the best bathroom fan by first deciding what capacity fan is most suitable for your bathroom. A bathroom fan’s ability to move air is measured in Cubic Feet per Minute (CFM). Your ideal bathroom fan should have a CFM rating high enough to replace the entire air in your bathroom 8 times per hour. Here is how you calculate your bathroom fan’s CFM requirement. If your bathroom has a high ceiling, multiply the width x length x height of the bathroom. Then divide by 60 (minutes in an hour). Then multiply by 8 (number of air refreshes per hour). For example, for a 10 feet wide by 12 feet long bathroom, with a 10 feet high ceiling you would need a 160 CFM rated bathroom fan.

10 x 12 x 10 = 1200
1200 ÷ 60 = 20
22×8 = 160 CFM rated bathroom exhaust fan
It is better to get a fan that is a little “too big” than “too small”. Fan’s noise rating is also important. Fan noise is measured by “sones” – a scale that represents degrees of loudness. A fan with a rating of 0.5 to 1.2 sones will be exceptionally quiet. A rating of 1.5 to 2.0 sones is very good while ratings in excess of 4.0 sones tend to be noisy. If you are replacing or upgrading a bathroom extractor fan, the diameter of the duct connector on the new fan maybe larger than the size of your old duct. To maximize performance, try to match your duct diameter to the new fan. Using a smaller duct will decrease your fan’s performance and significantly increase noise due to air flow restriction.
