Q: Why is the tower fan not quiet?

A: Note: It is 44, 55 and 66db at low, medium and high speed respectively.

The noise level is about 44dB at low 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 will be reduced. Please try the following steps.

If you can, please take a short video and send it to support@dreo.com as soon as possible.

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