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.
