Why is the tower fan not quiet?

The noise level is about 35dB at the lowest speed. The higher the gear setting of the tower fan, the louder the noise will be. We recommend turning down the fan speed to see if the noise decreases. 

 

Please try the following steps

1. If you can, please take a short video and send it to [e-mail] as soon as possible.​

2. Please relocate the fan.​

3. Then try to apply lubricant to the base if the noise only happens while the fan rotates.
