What Customers Are Saying

Customers overwhelmingly praise this bathroom fan for its exceptional quietness, easy installation, and high-quality design. The whisper-quiet operation at maximum 110 CFM airflow is consistently highlighted, with many noting near-silent performance even at full speed. Installation is straightforward thanks to the flexfit bracket and adjustable mounting system, with most completing it without professional help. The sleek design, bright LED light, adjustable CFM settings, and DC motor soft start reinforce perceptions of premium quality. A few mention minor ductwork compatibility challenges or price concerns, but most consider it worth the investment.

Quite deceiving. It’s not 0.3 sones at 110 CFM.

Would Recommend

It’s around 1 sones at 110. Not only that, junction box isn’t needed. It gets into the way so much. Even the plate that the junction box is attached too. Make it easier. Make it so that the adapter/the plastic hole can just snap onto the housing of the motor, and I turn it, and it is locked into position.
