Troubleshooting
If you encounter issues related to the filter, consider the following:
- Filter Indicator Light Remains On After Replacement: After replacing the filter, you may need to manually reset the filter life indicator on your air purifier. Refer to your air purifier's main user manual for specific instructions on how to reset the filter life.
- Reduced Airflow or Odors Persist:
- Ensure the filter is installed correctly and the front cover is securely closed.
- Check if the washable pre-filter is clean. A clogged pre-filter can restrict airflow.

- Unusual Noise: Ensure the filter is seated properly within the air purifier. A loose filter can cause vibrations.
