Silent and very effective
[This review was collected as part of a promotion.] Works great for us, stays silent at night in auto mode and we've noticed a definite increase in air quality and decrease in odors

I love my i35
[This review was collected as part of a promotion.] Very good air purifier with lots of features. You can control it remotely and keep track of the air quality. Makes a huge difference especially with the odor filter.

Love our 25i's and getting two more 35i's
Have these in kids bedrooms. They are aesthetically really pleasing and so small! The 25i's are super quiet on low and also completely tolerable when on high. I use the App and have them set to Automatic, so fan speeds change depending on particulates measured by the devices. Always goes in high when we're cooking. I'm also getting two 35i's for the living and dining. The App is great: super easy to use and to control all devices quickly and remotely.
