The Broan-NuTone AER110RGBL ChromaComfort Ventilation Fan is a well-rounded option for those seeking a bathroom exhaust fan with added features. With a rating of 110 CFM, it effectively clears fog and moisture in spaces up to 105 sq. ft., making it ideal for small bathrooms. It operates at a relatively low noise level of 1.5 Sones, which is a significant advantage for users looking for a quieter environment.

One of the standout features is its Bluetooth capability, allowing users to control the fan and customize lighting with a smartphone app or a wireless wall control. The ability to choose from 24 colors adds a fun, personalized touch to your bathroom lighting, which could enhance your experience.

On the downside, the fan’s primary usage is tailored for indoor bathrooms rather than attics, which may limit its appeal for those specifically looking for attic ventilation solutions. Also, the fan requires batteries for the wall control, which could be seen as an inconvenience if they need to be replaced frequently. The 3-year warranty is decent, but some may prefer longer coverage for peace of mind. In terms of design, while its white finish blends well with most interiors, it may not stand out for those looking for more aesthetic options. The fan also lacks reusable elements, which could be a concern for environmentally-conscious consumers.

Buying Guide for the Best Attic Fans

Choosing the right attic fan can significantly improve the ventilation in your attic, helping to regulate temperature, reduce moisture, and extend the life of your roof. When selecting an attic fan, it's important to consider several key specifications to ensure you get the best fit for your needs. Understanding these specs will help you make an informed decision and choose a fan that will effectively meet your requirements.
CFM (Cubic Feet per Minute)CFM measures the volume of air the fan can move per minute. This spec is crucial because it determines the fan's ability to ventilate your attic space. For smaller attics, a fan with a lower CFM (around 800-1200) may suffice, while larger attics may require a higher CFM (1500-3000) to ensure adequate ventilation. To pick the right CFM, calculate the volume of your attic and choose a fan that can replace the air in the space every 2-3 minutes.
Power SourceAttic fans can be powered by electricity or solar energy. Electric fans are typically more powerful and can run continuously, making them suitable for larger attics or areas with high heat. Solar-powered fans are more energy-efficient and environmentally friendly, but they may not be as powerful and depend on sunlight to operate. Choose an electric fan if you need consistent, high-power ventilation, or a solar fan if you prefer an eco-friendly option and live in a sunny area.
Thermostat and Humidistat ControlsThese controls allow the fan to automatically turn on and off based on temperature and humidity levels in the attic. This feature is important for maintaining optimal conditions without manual intervention. A thermostat will activate the fan when the attic reaches a certain temperature, while a humidistat will do so based on humidity levels. If you live in a region with extreme temperatures or high humidity, these controls can help maintain a balanced environment in your attic.
Noise LevelThe noise level of an attic fan is measured in decibels (dB). This spec is important if your attic is near living spaces, as a noisy fan can be disruptive. Fans with lower dB ratings (below 50 dB) are quieter and more suitable for homes where noise is a concern. If noise is not an issue, you can opt for a fan with a higher dB rating. Consider the placement of your attic and how much noise you are willing to tolerate when choosing the noise level.
Installation TypeAttic fans can be installed on the roof or gable. Roof-mounted fans are more effective at removing hot air since they are placed at the highest point of the attic. Gable-mounted fans are easier to install and maintain but may not be as efficient in ventilating the entire attic. Choose a roof-mounted fan if you need maximum ventilation efficiency, or a gable-mounted fan if you prefer a simpler installation process.
Durability and WarrantyDurability refers to the fan's ability to withstand harsh attic conditions, such as high temperatures and humidity. A durable fan will have a longer lifespan and require less maintenance. The warranty provides assurance of the fan's quality and the manufacturer's support. Look for fans made from high-quality materials like metal or heavy-duty plastic, and check for a warranty of at least 5 years. Choose a fan with good durability and a solid warranty to ensure long-term performance and peace of mind.
