How Many Sones is a Quiet Bathroom Fan?
When selecting a quiet bathroom exhaust fan, your first consideration is the sone rating. This is a measure of how loud the fan is and is expressed in terms of “sones.” The lower the sone rating, the quieter the fan. For reference, a conversation between two people is about four sones.
Generally, a sone rating of 3.5 is considered a quiet bathroom fan. However, the quietest bathroom exhaust fans can have a sone rating of 1.0 or less. As a comparison, a sone rating of 1.0 is equivalent to a refrigerator humming.
The sone rating is often determined by the size of the fan and the motor. The fan size is calculated in cubic feet per minute (CFM). This indicates how much air the fan can move in one minute. The larger the bathroom, the higher the CFM rating you will need.
Sones vs. Decibels
The sound levels of the bathroom exhaust fan will depend on the fan speed. The decibel level will be different depending on how powerful the fan is.
The greatest decibel levels are found on the loudest fans. Most cheaper fans have a rating of 4.0 or higher.
- A sone rating of 4.0 is about 48 decibels
- A sone rating of 1.0 is about 28 decibels
Many believe a bathroom fan with a noise level of 33 decibels (1.5 sones) or less is considered an ultra quiet bathroom fan.

What CFM for a Quiet Bathroom Fan?
CFM is an acronym for cubic feet per minute. This acronym describes how much air a fan motor can move in one minute.
The size of your bathroom determines the CFM rating you need. The CFM is calculated by multiplying the room’s cubic volume by 0.13.
For example: Length x Width x Height = Cubic Square Feet
Cubic Square Feet x 0.13 = CFM Rating
For smaller bathrooms, like 8′ x 5′ with 8′ ceilings, you’d have:
8 ft x 5 ft x 8 ft = 320 ft3
320 x 0.13 = 41.6 CFM
We recommend a bathroom exhaust fan with at least a 40 CFM rating. Most quiet exhaust fans have a minimum rating of CFM 50. Most bathrooms will need either a 50CFM or 80CFM rating.
Larger bathrooms will need a larger bathroom exhaust fan.
