Query: Motor noise too loud

The white noise that comes from the air whooshing from the machine is fine but unless the cap and collar are all the way open the noise from the motor can be heard also. It's a low pitched noise and I found it very distracting. I got the dual speed one and this happens at both speeds. I thought the machine itself was too loud and so I wanted it on the lower speed and with the collar turned a bit to put out less noise but this made the noise from the motor too distracting. I tried putting it farther away but the low pitched noise from the motor travels better so that didn't help. I returned it and intend to get an electronic device where I can get pure white noise with a volume control.
