Settings
| Setting | Options | Default | Notes | Source |
|---|---|---|---|---|
| Fan speed | Low (1 indicator), medium (2), high (3), turbo (4) | Turbo is the loudest speed but cleans air the quickest. For best results, or for a specific issue such as smoke, run turbo for 15 to 20 minutes before using a lower speed. | Source: Controls & Display; Using Your Smart Air Purifier, pp. 5, 9 | |
| Auto Mode | Tap the Auto Mode button | Fan speed follows the AirSight Plus reading: blue (PM2.5 0–35 µg/m³) Sleep Mode, green (36–75) low, orange (76–115) medium, red (above 115) high. Auto Mode does not use turbo. After switching on, the ring stays blue for 5 seconds while the sensor reads the air. | Source: Using Your Purifier (cont.), p. 10 | |
| Quiet, Efficient and ECO Auto Mode | Choose in the VeSync app | Quiet Auto Mode uses only low and medium speeds. Efficient Auto Mode runs turbo for a time based on the room size you enter, then follows the sensor. ECO Auto Mode switches the fan on and off while air quality is Very Good. | Source: Using Your Purifier (cont.), p. 13 | |
| Light Detection | Off by default; hold the display button for 3 seconds or use the VeSync app | Off | In a dark room the display goes off, and Auto Mode does not use the high or turbo fan speeds. | Source: Using Your Purifier (cont.), p. 12 |
| Sleep Mode | Tap the Sleep Mode button | Uses a fan speed lower than low and turns the display off after 6 seconds. | Source: Using Your Smart Air Purifier, p. 9 | |
| Timer | 1 to 12 hours on the purifier in 1-hour steps; 1 to 24 hours in the VeSync app | After selecting hours, the display returns to the PM2.5 reading after 5 seconds and the timer starts. Tapping the Timer button while a timer runs shows the remaining time. Tap it repeatedly until the display reads "-H" to cancel. The purifier remembers the last timer setting but cancels the timer when turned off, and the timer must be restarted. | Source: Using Your Purifier (cont.), p. 11 | |
| Display Lock | Hold the Display Lock button for 3 seconds | The display locks and buttons do not respond to taps. The VeSync app can still change settings. Hold the button for 3 seconds again to unlock. | Source: Using Your Purifier (cont.), pp. 11, 13 |
