This is a good quality air purifier with high volume of plasmacluster ion and energy efficient. There is only one challenge in connection to the app. You can easily follow the instruction but for me it did not work at first. I figure out that it has a compatibility issue with Wi-Fi mesh technology router. So I connected it with normal Wi-Fi router provided by the ISP. I can monitor the air quality anywhere and command as well google assistant I created a vlog on this, you may check this out (Yopi) Youtube Channel – https://youtu.be/dWuy-aLzzqE
