Bed Fan For Under Sheets. The cool air from the bed fan flows up your body removing the trapped heat from around your body, under your duvet and sheets before. The unique bfan bed fan is a silent rotary fan that sits on the floor at the end of your bed and gently blows cool air into your bed under the duvet to prevent you from getting hot and sweaty whilst trying to sleep.
When placed at the foot of the bed the air from the bfan® will help keep you cool all night long. 2) adjust the top of the bfan so it is at least 2 inches above the top of your mattress. 1) simply position the bfan® anywhere against the foot of your bed.
