white noise fan

Small electric tabletop/desk fans and fan-based white-noise machines. Fans are sold as quiet desk or bedside circulators, while the sound machines use real fan-generated white noise to create a steady masking sound.

They run on mains power using an electric power cord; these examples do not use batteries.

Most units offer two fan speed settings. Some sound machines also include adjustable tone and volume controls so you can personalize the white-noise sound.

Small fans typically include adjustable tilt or pivoting heads to direct airflow. Sound machines offer controls such as dual speeds plus adjustable tone and volume to modify the sound profile.

Warranty coverage varies by model. Examples in this set include a 1-year limited warranty and a 5-year limited warranty.

They’re marketed for bedside and desk use and for small rooms, dorms, and offices. Sound machines are specifically highlighted for improving sleep, enhancing privacy in offices, soothing babies, and calming pets.
