We did not hear any noise and this air purifier does the job perfectly

Easy to set up, runs great

Quiet, efficient and great profile

Took the smell of dog away.

Can't believe how quiet it is and how good my air smells!

So far it seems to be doing a bang up job.

Quiet when operating. Blends in, hardly noticeable as far as fan noise. Stylish design

I just bought it, great air purifier.

Appears to function properly and is a convenient size to clean the air in my office.

Great product. Works great on pet hair and refreshing the air.
