The iAdaptAir purifier from Air Oasis, is now controlled via Alexa by Amazon. You can link to your Air Oasis App Account and control fan speed, UV lights, ion generators and smart-mode. Set sleep timers (2 hours, 4 hours, and 8 hours), as well as activate preset settings that were created within the app. You can lock or unlock the unit so children cannot change settings. There is also a night/lock mode that will turn on/off the backlit buttons
