Factors to Consider When Choosing a Bathroom Exhaust Fan

If this dampness is not addressed in good time, it may encourage the growth of mold and negatively impact on the air quality. Having an exhaust fan can be very instrumental in protecting your walls and fixtures as well as removing unpleasant odors. Below are some of the tips to help you in choosing the right fan for your bathroom.

Find the Correct Airflow Rating for the Bathroom Size

All the ventilation fans in the market have an airflow rating which is usually measured in cubic feet per minute. In order to get the right rating, you are supposed to measure the room so as to determine its square footage. According to the Home Ventilating Institute, a square foot of your bathroom area requires a rating of 1 cubic feet per minute and the minimum should be 50 cubic feet per minute. Rooms that have ceilings which measure 8 feet tall and above, they may need higher rated fans.

Consider the Noise Level

The noise level of exhaust fans is usually measured in sones. To give you an idea of the noise level, one sone is more or less like the sound of a refrigerator running. Noise levels for fans measure anything between 1 and 4 sones. Ensure the sound level you choose is comfortable and you can tolerate it for about 15 minutes. If you want quieter fans, they come at a premium.

Extra Features

Exhaust fans come with extra features including heaters, lighting and automated timers. Some of the more advanced fans come with a humidistat that senses the humidity level in the bathroom and turns the exhaust fan on and off automatically.

The Type of Fan You Want

There are different types of fans available and your choice will mostly likely be affected by the proximity to existing duct systems and the available space. Some of the common types of exhaust fans include:

• Ceiling mounted fans – These fans are mounted onto the ceiling and they vent to the outside through ducts or the roof. It is the most common type of bathroom fans.

• Wall mounted fans – These are installed on the outside walls and pull air to the outside. They do not require ductwork.

• Inline fans – These can be installed either on the ceiling or wall, however, the motor is positioned in between the ducts. They remotely pull air to the outside. They are very quiet in operation and appropriate in places where ceiling space is limited.

Installing an exhaust fan can be a simple DIY project for homeowners who are a bit technical, but for those who may not want or know how to do the connections to the ductwork, a skilled HVAC expert may be of help.
