We are looking for a small Room Air Circulator Floor/Table Fan that does NOT produce a low hum or vibration from the motor.

The purpose of this is just to circulate the air a little in our bedroom at night, and to provide some white noise.

We get the white noise from any fan, but all the fans we have tried also produce a low hum or vibration from the motor. This makes it difficult to get a good night's sleep.

Any ideas would be welcome.

Thanks.

Mac
