If your air purifier has lost connection and does not reconnect by itself after a few minutes, the first step is to try to onboard the air purifier to the Blueair app again:
- Open the Blueair app
- Open your air purifier's page, go to Product Settings and Delete your air purifier
- Click on "Connect product" and follow the instructions to connect the air purifier again.
If that did not help, please try the following:
- Log out from the Blueair app
- Make sure that you are not signed in the Blueair app on another phone. For instance if a family member is sharing the Blueair app account with you, please ask them to sign out from the Blueair app account
- Log in with your Blueair credentials
- Reboot your air purifier (unplug, wait 15-30 seconds and plug again)
- Delete your air purifier from the app
- Connect your air purifier to the app again
- When the air purifier is online, try to change the settings again.
