10 Best Exhaust Fans 2025 in the United States

The iLIVING 12" Wall Mounted Shutter Exhaust Fan is designed to move a strong amount of air, with a capacity of 960 cubic feet per minute (CFM), making it suitable for large spaces like garages, workshops, or greenhouses up to 1400 square feet. This means it can effectively clear out stale or humid air quickly. It offers variable speed and temperature controls through its Thermospeed controller, allowing you to adjust airflow and set it to activate within a temperature range from 32 to 130°F, which can help maintain better air quality and comfort.

The fan is built with durable galvanized steel and aluminum parts, and it comes with corrosion-resistant features, so it should hold up well in tougher indoor environments. It mounts on walls and plugs into a standard outlet, making installation straightforward for most users. On the downside, the noise level is about 65 decibels, which is similar to normal conversation volume and might be noticeable if you prefer a quieter environment. While it uses 65 watts of power, its efficiency rate is moderate, moving about 15 cubic feet per minute per watt, so it’s not the most energy-saving option if you run it constantly. It also includes automatic shutters that open and close with the fan, helping prevent outside air or pests from entering when off.

Customer feedback is favorable, with many appreciating its power and controls, though some might find the sound level a bit loud for certain indoor spaces like bedrooms. If you need a strong, wall-mounted exhaust fan with adjustable speeds and temperature settings for a large indoor area where noise is less of a concern, this fan is a solid choice.

The Air King 20" Whole House Window Fan is a strong option for improving air circulation or exhaust in a home or office. It provides a high airflow capacity of 3560 cubic feet per minute, allowing it to move a large amount of air and potentially cool or refresh an entire space. The fan features three speed settings to adjust airflow depending on your needs, and its permanently lubricated motor ensures smooth operation with minimal maintenance. Designed to be mounted in a window, it includes storm guards that let you close the window behind the fan to protect against weather without blocking airflow. The fan's steel blades and grill offer durability and aim for lasting use.

The noise level is around 64 decibels, which is noticeable—comparable to a busy office or a running dishwasher—so it might be a bit loud for very quiet rooms or light sleepers. It uses 170 watts of power, which is moderate but not the most energy-efficient option available, so electricity costs may be a consideration if used frequently. Installation requires some assembly, and mounting hardware is included. However, it is not cordless and must be near a power outlet. Suitable for garages, basements, or general home and office use, this fan delivers strong performance but may not be ideal for those who prioritize ultra-quiet operation or the highest energy savings.

The Delta BreezRadiance RAD80 is an exhaust bath fan designed to handle bathroom ventilation needs effectively. With an airflow capacity of 80 CFM, it is well-suited for moderately sized bathrooms, ensuring proper air circulation and moisture control. One of its standout features is its quiet operation at 1.5 sones, making it relatively unobtrusive during use. Additionally, it includes a built-in heater, which can be a valuable feature for those seeking added warmth during colder months.

The fan operates using a DC brushless motor, known for its longevity and reliability, meaning it should outlast many other household appliances. The galvanized steel construction adds to its durability and resistance to corrosion, which is particularly important in a humid bathroom environment. Safety is also considered, with a fan impeller that stops if obstructed, reducing the risk of damage or fire. Energy efficiency is decent, with an efficiency rating of 7.0 CFM/Watt, which should help keep energy consumption lower.

One potential drawback is the noise level, stated as 80 dB in the specs, which seems inconsistent with the 1.5 sones rating and might indicate a misprint. The additional heater feature adds significant value, although it could also complicate installation and maintenance. This fan is best suited for users looking for a reliable, quieter, and feature-rich ventilating solution for their bathroom.
