The QuietSet® Sleep Fan creates gentle pink noise to help promote a more restorative night’s sleep. Pink noise is a mix of high and low frequencies that sounds more balanced and natural than white noise. You can enjoy this soothing pink noise with or without airflow, making it suitable for any season. The compact design is easily portable and fits perfectly on a nightstand, dresser or the floor. This sleep fan features 3 powerful cooling speeds, a pivoting base that lets you direct the airflow, and wide area oscillation for even cooling coverage. Additionally, it boasts automatic dimming control panel lights and an auto-off timer, making it an excellent choice for year-round sleeping comfort.
