What to do if the filter indicator is blinking on my Blueair HealthProtect 7400?
- Nnicole68Jul 25, 2025
If the filter indicator is blinking, the air purifier has reduced airflow speed, or a filter warning appears on the screen, ensure that a main filter, or an original Blueair filter, is properly inserted in the air purifier. If not, insert it. If you are still experiencing issues, try changing to an original Blueair filter.
