When it comes to home ventilation, the bathroom exhaust fan is often referred to as a bath fan and plays a crucial role beyond just your bathrooms. Exhaust fans can be added to closets, mud rooms, laundry, workout spaces, and more while eliminating humidity, odor, and airborne particulates. It's a silent hero working tirelessly behind the scenes to keep your home's indoor air quality fresh and healthy. Whether you're planning to replace an old unit, install a new one, or upgrade your current fan, this comprehensive buying guide is here to help guide you through the process. From understanding the fundamentals of bath fans to exploring their versatile applications throughout your home, we'll help you make informed choices for better air quality.

Find a noise-reducing motor that matches your current model and brings tranquility back to your bathroom oasis. Let's see if we can find you the perfect match!


How to Find Your Model Number


To find the model number, remove the grille by pulling down two inches. Reach behind the grille and squeeze the mounting springs to remove. Find the model label located in the corner, closest to the outlet. Some fans have the model number stamped into the motor plate instead of a sticker.

If your model number can't be found through the model generator (because its probably ancient), please call our air ambassadors, AKA our customer service team, which can help provide you with more options. 

If the motor upgrade alone doesn't do it for you, consider a fun cover upgrade as well. You don't have to sacrifice style for quietness. Explore our range of vibrant and stylish covers that will bring a touch of personality to your bathroom.

Important Factors to Consider 

First things first, let's determine the right size for your fan. Our experts suggest that your bath fan should be able to remove the entire volume of air in the room eight times per hour. To figure out how many Cubic Feet per Minute (CFM) your bathroom needs, follow these simple steps: 

  1. Measure your bathroom's length, width, and height. For example, let's say your bathroom measures 10 feet wide by 6 feet long and has a ceiling height of 10 feet. Multiply these numbers together (6 x 10 x 10), and you get a total cubic footage 600.
  2. Divide the cubic footage of your bathroom by 60 minutes per hour to determine the CFM rating needed for one air exchange per hour. In our example, 600 cubic feet divided by 60 minutes per hour equals 10 CFM for one exchange. So far, so good!
  3. Considering the recommended eight air changes per hour, multiply the CFM per hour by eight. In our example, 10 CFM x 8 exchanges equal an 80 CFM rating. Voila! At the very least, your bath fan should be able to move 80 CFM to remove indoor air pollutants effectively. 

Remember, you can always choose a fan with more CFMs than your room needs for extra oomph!

If you are installing a new fan in open construction (no drywall is present) you can easily install the fan wherever it is needed. 
When replacing an existing bathroom exhaust fan, carefully measure the opening in your ceiling or wall. In some cases you may be able to replace your existing fan with one that is the same size. If you are upgrading or replacing with a larger model, you may have to cut some of the drywall to ensure a proper fit. Be sure to measure the height as well. Some newer models are taller than older models. 

Some models offer Room Side installation. This means you do not have to access the unit from the attic in order to replace it. 

Proper ducting is essential for efficient and effective exhaust ventilation. The ducting size plays a significant role in maintaining optimal airflow and reducing noise. Consider the following points when determining the ducting size for your exhaust ventilation system:

  1. Sizing Guidelines: Choose ducting size based on the capacity of your fan and the distance the air needs to travel. Too small ducting can restrict airflow, reducing the system's efficiency. Generally, larger ducts are better for minimizing air resistance and noise.
  2. Fan Capacity: Match the ducting size to the fan's capacity. Larger fans might require bigger ducts to accommodate the increased airflow.
  3. Duct Length and Turns: Longer duct runs, and multiple turns can increase air resistance. If your installation requires lengthy ducting, consider upsizing the duct to compensate for the potential loss of airflow.
  4. Noise Reduction: Properly sized ducting can help reduce noise generated by the exhaust fan. Using larger ducts and keeping the airflow velocity within recommended limits can contribute to quieter operation.

Sones are used to quantify how loud a sound is perceived by the human ear. When it comes to exhaust fans, a lower sone rating indicates quieter operation.

  • Less than 1 sone Whispers
  • 1 sone- Refrigerator Noise
  • 2 sones- Calm Office
  • 3 sones- Normal Conversation
  • 4 sones- TV/Radio
  • 5 sones- Busy Restaurant
  • 6 sones- Sporting Event 

Integrating lighting with your exhaust ventilation system can enhance both functionality and aesthetics. Here's what to consider when selecting the lighting type:

  1. LED Lighting: Energy-efficient and long-lasting, LED lighting is an excellent choice for exhaust ventilation systems. It provides bright illumination while consuming less energy than traditional incandescent or fluorescent lights.
  2. Warm vs. Cool Light: Decide on the color temperature of the lighting based on the ambiance you want to create. Warm light (around 2700K-3000K) is more cozy and inviting, while cool light (around 4000K-5000K) is more suited for tasks and productivity.
  3. Dimmable Options: Consider exhaust ventilation systems that offer dimmable lighting options. This allows you to adjust the brightness according to your needs and mood.

Investing in ENERGY STAR-rated exhaust fans can lead to energy savings and environmental benefits. Here's why you should consider ENERGY STAR-rated fans:

  1. Energy Efficiency: ENERGY STAR-rated fans are designed to consume less energy without compromising performance. This translates to lower electricity bills and reduced environmental impact.
  2. Certified Performance: ENERGY STAR certification indicates that the fan has met strict efficiency and performance criteria set by the Environmental Protection Agency (EPA). You can trust that the fan will deliver optimal ventilation while using less energy.
    Environmental Impact: By choosing ENERGY STAR-rated products, you're contributing to the reduction of greenhouse gas emissions and promoting sustainable practices.
  3. Quality Assurance: ENERGY STAR certification ensures that the exhaust fan meets high standards of quality and performance. You can expect reliable and consistent operation.
  4. Incentives and Rebates: Depending on your location, you might be eligible for incentives, rebates, or tax benefits when you install ENERGY STAR-rated products. Check with local authorities or energy companies for potential savings.

Take a look at your current bathroom exhaust fan's control. Is there one control, or two? Some models and installations are set up for independent control of the fan and light. Some control both at the same time. And, in some special cases, a third control may power the bathroom exhaust fan's heating element. When selecting a new bathroom exhaust fan with added features, be sure to add or combine controls to optimize your new fan. If you are installing a bath fan with a built-in heater, pay special attention to the installation instructions because you will likely be required to install a new circuit breaker or connect to an existing breaker.
