The CFM (cubic feet per minute) rating of an exhaust fan indicates how much air it can move in one minute.
For a bathroom, a CFM of 50 CFM per person is recommended, while for a kitchen, 100 CFM per linear foot of cooking surface is recommended.
2. Choose a fan with the right noise level.
Exhaust fans can produce noise, so it is important to choose a fan with a noise level that is acceptable to you.
Look for fans that have a sone rating of 1.0 or less.
3. Consider the installation location.
Exhaust fans can be installed in the ceiling, wall, or window.
Ceiling-mounted fans are the most common, and they are usually the most effective at removing air.
Wall-mounted fans are less common, but they can be a good option if you do not have access to a ceiling joist.
Window-mounted fans are the least effective, but they are the easiest to install.
4. Choose a fan with the right features.
Some exhaust fans come with additional features, such as timers, humidity sensors, and motion sensors.
These features can be helpful for saving energy and improving air quality.
5. Look for a fan that is Energy Star certified.
Energy Star certified exhaust fans meet strict energy efficiency standards.
This means that they will save you money on your energy bills.
Here are some additional tips for choosing the right exhaust fan:
* Consider the size of the room.
* Make sure the fan is installed properly.
* Clean the fan regularly to maintain airflow.
* Replace the fan filter every 3-6 months.
