To confirm the air purifier model name you can check the product label at the bottom of your machine:

Please unplug your air purifier, then carefully lay it on its side. On the bottom of your unit, you will find a sticker with the MAC address and serial number for your machine.​

​

If your air purifier is connected to the Blueair app you can additionally view the MAC address by selecting your air Purifier in the app and navigating to Product Settings > Product Information. ​
