You should first confirm the air purifier model name to find which filters are compatible with your unit.
The name of your air purifier, corresponding filter, Serial Number and MAC addresses can be found labeled inside the fan part of your air purifier and in the Blueair app if you have a connected unit.
Check your model reference on the air purifier's label:
• Turn the air purifier off and unplug.
• Carefully rotate the white top counter clockwise to unlock and remove it from the unit
• Check the fan cover for the product and filter information
Check your model reference in the Blueair app:
• Open the Blueair app
• Select Product Settings
• Select Product Information
Once you know your model number, you can go to https://www.blueair.com/us/air-purifier-filters. Scroll down and select the model you have. All compatible filters and pre-filters will then be displayed. You can then click and order your filter as needed.
