How to choose the right exhaust fan

Exhaust fans are extremely necessary to maintain airflow in a home by allowing for ventilation to replace undesired air with fresh air in buildings. These are most commonly used in bathrooms and kitchen spaces but can be beneficial in many areas of the home.

What is an exhaust fan?

 An exhaust fan is typically used in a bathroom to remove humidity from the air to prevent mold and mildew. Reducing moisture will prevent future damage to your paint or wallpaper. Having an exhaust fan in your kitchen is not required; however, it is necessary to maintain the air quality by removing grease, smoke, and fumes that are present in the air when cooking. 

Things to consider when choosing an exhaust fan

When choosing a fan there are a lot of factors to keep in mind when deciding which will work the best for your space.

Considering where the fan will be located in the first step when deciding. Whether the room is on the first floor or top floor will play a big role in where the air will expel. Additionally, the room size determines the air volume flow rate (CFM) needed for proper ventilation.

Sound level is a factor you should not overlook when picking a fan. Exhaust fans are often loud and disruptive in your home. Their noise levels are measured in sones, with a higher number of sones equating to a louder fan. It is recommended that you get a fan with a noise level of 1.0 or less.

Energy Efficiency is an important factor to consider when picking an exhaust fan. Picking an Energy-Star rated fan can help reduce your energy bill. Many bathroom fans come with an on/off timer, to save electricity; humidity sensors, which cause the fan to turn on only when moisture is present; or motion sensors, which turn the fan off automatically once someone leaves the room.

Types of exhaust fans

A wall-mounted fan is installed on an external wall of your house and enables the air inside to exit straight through the fan itself. This is a good option if you are on the first floor since it would be very hard to vent through the roof. Also, these types of fans require very little installation planning. 

Exterior exhaust fans are very similar to wall-mounted fans due to the fact that they both pull air from the interior of a space and expel it outside. These are ideal for spaces where noise reduction is wanted since the fan is outside.

Inline fans are mounted in line with the ductwork, bringing air from the inside and to the outside of the home. These fans are typically used in rooms with poor ventilation. They are good options for homeowners who want to keep their fan in a remote location such as the attic. An
