Note that when doing a factory Reset, the filter timer will be reset and the air purifier will be disconnected from the Blueair app.
How to perform a factory reset
- Press and hold the power button until all LEDs blink 4 times, then release. This can take from 15 to 30 seconds depending on the model.
- The factory reset will initiate after about 5 seconds when all LEDs will blink twice again, including the red filter light indicator (don't press any buttons before the lights blink twice).
- The air purifier will go to Standby mode after the factory reset is completed.
- Important! Your air purifier will show offline after a factory reset. That is normal. Please open the Blueair app, select "Connect" and follow the instructions to reconnect your air purifier again.
