When it comes to air purifiers, the O3 Pure is one of the more expensive options on the market. While it comes with some cool features, we weren‘t wowed by its performance. The O3 Pure has three fan speeds and a night mode, which emits less ozone.
It also has a timer for 1, 3, 5, or 8–hour sessions. The purifier comes with a remote control and can also be programmed to turn on/off when you open/close a door in your house.
The O3 Pure delivered top–notch performance when removing odors, but fell short in most other categories. It was the second–slowest purifier we tested in terms of cleaning the air and took roughly two hours to rid our testing area of odor—longer than most other purifiers we tested. It was also one of the loudest purifiers we tested.
