Exhaust Fan Purchasing Guide

Essential Considerations

1. What is your bathroom's size? Knowing the size of your bathroom is crucial for selecting the appropriate CFM (Cubic Feet per Minute). CFM indicates how much air your fan will circulate per minute, ensuring the chosen fan adequately vents your space without excessive or insufficient airflow.
   1. Bathrooms 45 square feet or smaller require a 50 CFM fan.
   2. For bathrooms measuring 46 to 75 square feet, opt for a 70 or 80 CFM fan.
   3. Bathrooms sized between 76 and 105 square feet need a 110 CFM fan.
   4. For bathrooms larger than 105 square feet, a 150 CFM fan is recommended.
2. What is the dimension of your ceiling's opening? You can determine this by removing the exhaust fan's grille and measuring the length and width of the opening. This is vital for ensuring your new fan matches or exceeds the dimensions of your existing one. Installing a smaller fan can lead to installation challenges.
3. Is there attic access above the bathroom? Attic access significantly influences the fan series you should purchase. If there is no access, select a fan designed for installation from the room side, such as the Roomside Series from Broan-NuTone. If you have attic access, you can choose from a wider variety of fans!
4. What type of fan do you prefer? The market offers numerous exhaust fan types, giving you flexibility in your selection. Consider the following options:
   1. Basic Fan: A standard fan that primarily moves air without extra features. These vary in size, noise level, and CFM adjustments.
   2. Fan with Light: This option combines a fan and a light source. Lights may be bulb-based or LED, with some options specifically designed to combat bacteria and mold.
   3. Humidity or Motion Sensing Fans: These intelligent fans can detect excess humidity and turn on automatically or activate when someone enters the bathroom.
      1. Humidity sensors kick in when moisture levels rise, then shut off as humidity levels normalize.
      2. Motion sensors activate the fan upon detecting presence, eliminating the need to turn it on manually.
   4. Bluetooth-Enabled Fans: A modern innovation, these fans can connect to your devices, letting you enjoy music while you shower!
   5. Fans with Heaters: Ideal for quickly warming a chilly bathroom post-shower, these fans provide heating and ventilation simultaneously.
   6. Decorative Fan/Lights: These units blend seamlessly into the ceiling and resemble ordinary light fixtures, eliminating the typical fan appearance.
   7. Upgrade Options: If your existing fan is functioning but lacks features, upgrades can enhance its performance or aesthetics.

Bathroom Exhaust Fan Evaluation

Ensure the fan you select is powerful enough for effective bathroom ventilation. The room’s size dictates the necessary CFM rating of the fan. As a rule of thumb, aim for at least 1 CFM per square foot. An undersized fan will struggle with moisture and odors, requiring longer operation times which can lead to increased motor wear. Follow these guidelines to identify the appropriate fan for rooms with 8-foot ceilings:

• A fan rated at 50 CFM is sufficient for bathrooms of 50 square feet or smaller.
• For bathrooms ranging from 50 to 100 square feet, approximate 1 CFM per square foot.
• For bathrooms exceeding 100 square feet, calculate the CFM needed for each individual fixture, allowing 50 CFM for each toilet, tub, and shower, plus an additional 100 CFM for a jetted tub.
• If your bathroom measures less than 50 square feet, a 50 CFM fan will suffice.
• For all sizes, extensive ductwork connecting the fan externally increases CFM requirements, especially if the ducts have bends.

Bear in mind that enclosed toilet spaces necessitate their own ventilation fan.

Finally, while aiming for accuracy in CFM ratings according to room size, consider upgrading to a slightly larger capacity fan. For instance, opt for a 70-CFM fan if your bathroom is 65 square feet.
