• Vacuum the outside of the air purifier regularly, especially the air inlets and outlets.
• Clean the pre-filters according to the instructions in the user manual (not all models have a pre-filters).
• Vacuum the inlet of the air quality sensor (not all models have an air quality sensor).
• When the filter change warning appears on the air purifier and in the app, replace the filter with a new Blueair filter.
