Control Panel and Display Features
The top surface has an OLED touch panel with these controls:
- Power button and mode switch
- Light adjustment control
- Child lock indicator
- Wi-Fi connection status
- Filter replacement reminder [5]
The air quality indicator uses four colors – green, yellow, orange, and red to show live air conditions [5]. The display’s brightness changes with the room’s light, so you can see it clearly without it disrupting your sleep [6].
Smart Features and Connectivity: Xiaomi Air Purifier 4 Compact Review

Both Alexa and Google Assistant work seamlessly with the purifier [11]. Compatible smart speakers or devices let users adjust settings, check air quality, and control simple functions through voice commands [7].
Smart Home Ecosystem Compatibility
Advanced automation becomes possible through the Mi Home platform’s Smart Scenes feature [9]. Users can link multiple compatible devices to create custom routines that adjust the purifier’s settings based on other smart home triggers [9]. The system also comes with practical features like sleep mode scheduling and child lock controls [10].
The purifier automatically adjusts its operation based on up-to-the-minute air quality readings [2].
