Nuwave Portable Air Purifier for Large Room up to 1361 Sq Ft with PM 2.5 Display Air Quality Sensor, H13 True HEPA Air Filter Remove 99.97% of Pets Hair Odor Dust Smoke with Double-sided Air Intake

Noise level is so quiet, I can sleep through nights. My air quality has been better since using the Sans. Overall, I would definitely recommend this unit.

Does a very good job. I bought for a small room and did 250 Square feet. If the air is dirty smoky it senses the air and will go to high speed. Its also quite and non disturbing. I've had it about 6 months and no issues.

fantastic . exactly as described. use it frequently and happy with it. multi- levels from simple to economic to ergonomic to 8 hour . clears out a 741 sq.foot apartment in about 3.5 hours.

The unit works very well and does a great job of eliminating odors and smoke but if your power goes out with any frequency be careful. After my power went out suddenly the unit now isn't able to run without a rattling sound and air flow is reduced. Checking the limited warranty power fluctuations are NOT covered so you will have to replace the unit yourself if it is damaged in this way. Update: After running overnight on a low setting the rattling sound has stopped and full power is possible once more, one star added back

This thing is quiet, but not silent. Its doing a good job on 1000 sq. ft. In Eco mode.

This air purifier has done a great job keeping down the dust in my bedroom. When I finally looked at it to clean it. The purifier had been working very hard. See pic. Thank you Nu Wave

Works great! Not too loud. Leaves my house smelling clean

Love it
