Verified Purchase

I have only had this one day and I can already feel the in how me and my daughter are breathing at night! It was very easy to set up. Just plug it in basically. Trying to get it to connect to my WiFi on the app took a few tries but other than that I have no complaints. I am a light sleeper and the sound while not completely silent it's low enough for me that it doesn't bother me at all. I have this one in my bedroom and it quickly clears smells that come upstairs from the kitchen. I really wish I would have invested in an air purifier sooner! It's also light weight I have muscle weakness so I have trouble picking things up and carrying them but this was very easy for me to handle and move to the perfect spot in my room. So far I really have zero complaints and would purchase again.

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.

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.
