For quiet bathroom ventilation the fan should be rated at 1.0 sones or less.

Are 1.5 sones loud?

Fans rated at 1.5 sones are very quiet, and low-capacity fans rated as low as 0.5 to 1 sones are nearly inaudible. Since central ventilating fans run for extended periods of time, they should be no louder than 1.5 sones if they are mounted in the living space.

What CFM should my range hood be?

To power your range hood, you need at least 100 CFM for every 10,000 BTUs of your stovetop. For example, a 100,000 BTU stove needs at least a 1000 CFM range hood. For electric stoves, multiply the stove width by 10. So, for a 42” electric stove you want a range hood with at least 420 CFM.

How do I calculate CFM for bathroom exhaust?

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.

Is 66db loud?

0 dB is considered the threshold of human hearing and 120-140 dB is considered the threshold of pain. That means a sound so powerful, it will make your ears hurt. 60 decibels is right in the middle of this range between no sound at all and painfully intense sound. 60 dB is the equivalent of a normal conversation level.

What does CFM stand for in fans?

When deciding the size of your exhaust fan, you need to measure the size of your bathroom in metres. You will need to measure height, length and width. Then you need to multiply your measurements. For example, a bathroom that is 3m long by 2m wide by 3m high, you would get 18m3.

What is a CFM rating?

CFM is cubic feet per minute, which indicates the compressor’s flow rate – or the amount of air that a compressor can produce at a given pressure level. Typically compressors that have higher CFM ratings are able to provide more air, which makes them ideal for larger applications.
