App and connectivity issues

If you cannot connect your Protect air purifier to the WiFi via the Blueair App, please try the following steps:


Place your air purifier close to your phone and router during set up:

1. Ensure the smartphone you have the Blueair App opened on is within 3 feet (1 meter) of your air purifier and the router during set up. Once you have successfully paired your air purifier you can place it at your desired location.

2. Make sure that your air purifier is plugged in and powered on.

3. Open your App and select "Connect Product" and follow the instructions.

Update the Blueair App:

Open your App Store in your phone and ensure you have the latest Blueair App version

Activate Bluetooth:

Ensure Bluetooth is enabled in your smartphone's settings

Check your router:

Ensure the following:

1. Internet is currently running
2. You are using a 2.4Ghz network
3. Deactivate VPN
4. Open your Blueair App and try to connect your product again

"Offline" in the App

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.

If the air purifier does not connect, please check the "I cannot connect my air purifier" FAQ or contact us.

The firmware of my device is updating. How much time does this take?

The app notifies you every time the firmware in your device is being updated.

During the update, you must keep your air purifier connected to the Wi-Fi to have the firmware update complete. It is imperative you do not unplug the air purifier from the wall during any firmware updates.


The update should take a few minutes. Please do not disconnect your unit during the update!
If the update takes longer than a few minutes:

• Ensure your air purifier is within the router range.
• Leave your air purifier ON and connected to the WiFi. Do not unplug the air purifier during the update.
• Limit the number of connected devices or network activity while the update is in progress.

What to do if the air purifier seems to be stuck in the “firmware update” for over 30 minutes?

• Turn off the Wi-Fi network.
• Attempt to connect to a different Wi-Fi network or personal mobile hotspot.
• Upon connecting to a new Wi-Fi network or hotspot, the device will attempt to update again.
