The ventilation fan may not be the most glamorous part of your bathroom, but it plays a vital role in keeping things fresh and comfortable. Bathroom fans help to prevent mold and mildew growth by removing excess moisture from the air. When it comes to selecting the perfect fan for your home, considering factors such as size, noise level, and energy efficiency is essential. Here are some tips on how to choose the right bathroom vent fan.

Energy Efficiency

You want a fan that gets the job done efficiently. Look for a high CFM (cubic feet per minute) rating, as it means the fan can move more air per minute, resulting in better ventilation. Energy-efficient fans can help you save money on your energy bills. Energy Star rated fans are designed to use less energy and be easily recognized. This can mean that your fan can be using 50 percent less energy than a traditional fan.


In the last section, we talked about choosing a fan with a high CFM rating. The CFM rating measures the amount of air that the fan can move. Look for a fan with a CFM rating that matches the size of your bathroom. A good rule of thumb is to choose a fan with a CFM rating of at least 1 cubic foot per minute per square foot of bathroom space. So, for a 100 square foot bathroom, you would need a fan with a CFM rating of 100.

Bathroom Size

The size of your bathroom will determine the size of the vent fan you need. You can calculate the size of your bathroom by measuring the length, width, and height of the room. Multiply these three measurements to get cubic footage of the room. For example, if your bathroom is 10 feet long, 8 feet wide, and 9 feet high, the cubic footage would be 720. You will need a fan that can handle this amount of cubic footage. If you choose a fan that is too small, you will not get the moisture eradication that you are looking for. If you decide that bigger is better, you can run the risk of too much noise and improper functioning. This is why it is important to find the fan that is the perfect fit for your space.


Nobody wants a bathroom vent fan that disrupts any peaceful time you are spending in the bathroom. So, pay attention to the noise level. Look for fans with a low sone rating, which measures how loud the fan is. The lower the sone rating, the quieter the fan. Shoot for something around 2 or less, and you’ll be able to enjoy some peaceful bathroom moments, such as a soak in the tub after a long day at work.

Choosing the right bathroom vent fan is an important decision. You can check customer reviews for other’s experiences with the fans you are looking at. They can give you insights into performance, durability, and overall satisfaction. With the right fan, you can keep your bathroom clean, dry, and odor-free.
