4. Maintenance and Filter Life
To maintain optimal performance of your HIMOX AP01 Air Purifier, regular filter replacement is crucial. The filter's lifespan depends on usage and air quality.

5. Troubleshooting
If you encounter issues related to your HIMOX AP01 replacement filter, consider the following:
- Filter Not Fitting Properly: Ensure you are using a genuine HIMOX AP01 replacement filter. Unofficial filters may not fit correctly or provide optimal performance. Double-check the alignment when inserting the filter and securing the base cover.
- Filter Change Indicator Remains On: After installing a new filter, make sure to reset the filter indicator by pressing and holding the appropriate button (refer to Section 3, step 7) for at least 5 seconds.
- Reduced Airflow or Odors Persist: This may indicate that the filter is heavily soiled and needs replacement, even if the indicator has not yet activated. Consider replacing the filter more frequently in high-pollution environments.
- Unusual Noise: Ensure the filter is seated correctly and the base cover is securely locked. A loose filter can cause vibrations.
