Very quiet. Nice compact round, tall shape. Sits on equally well on floor, table or desk. Filters are easy to change and this is very reasonably priced for what it does. The touch switch is a little too unsensitive – takes a couple of hits in just the right place to turn it on. The HEPA filters emit a strange sweet/milky-smelling odor.
