“I love that I can operate it from anywhere with the app. I can get it going before I get home from being outdoors. It is a very quiet machine. It has night mode and will dim or turn off all lights on the machine.”

Lesann

“I like having a one for each high-traffic room such as our master bedroom, office, and living room. Although this one was intended for our office, it is by far the most attractive air purifier I have yet to see, so I swapped it for the one we had in our living room.”

MrsAdams

“The unit will automatically adjust according to the air quality, and there is a light indicator letting you know how it accesses the value. You can also set it manually, with three fan speeds, and wireless capabilities.”
