One night, I woke up coughing and my husband turned the air purifier and the coughing instantly went away. When we turned it on it showed that the air quality was not good, but it was nice to know that it works and it works great!

Didn’t expect to much from such a small unit. I was wrong. Performed above expectations in a 350 sf room. I definitely recommend this unit.

Just Buy It!
My CPAP filters are the proof these babies do their job! The CPAP filter stays cleaner for over a week which means I can replace every 2 weeks instead of every few days.
My wife sleeps better, we sneeze a whole lot less and taken in much cleaner air.
Have you ordered yours yet?

We’ve got baseboard heating in our home so it gets stuffy and dusty in our house until we reach AC season. This air purifier has made a huge difference for my dust allergies and we’ve noticed an improvement in air quality. I will definitely be getting another one for our bedroom. The smart function is a nice bonus. We purchased this after extensive research and are extremely happy with the device.
