5. Maintenance
Regular filter replacement is crucial for maintaining the efficiency and effectiveness of your air purifier. The lifespan of the filter depends on air quality and usage frequency.
- Replacement Frequency: We generally recommend replacing the filter every 2-3 months.
- Filter Indicator: The air purifier is equipped with a filter reset button and an indicator light. When the filter needs to be replaced, this indicator will flash red.
- Cleaning: The filter itself is not washable. Do not attempt to clean the HEPA or activated carbon layers with water or other liquids, as this can damage the filter and reduce its effectiveness.
6. Troubleshooting
If you encounter issues after replacing your filter, consider the following:
- Filter Indicator Still Flashing Red: Ensure you have pressed and held the filter reset button on the air purifier's control panel for the required duration (typically a few seconds) after installing the new filter. If the light persists, try unplugging the unit for 10 minutes and then plugging it back in and resetting again.
- Reduced Airflow or Odor: If you notice reduced airflow or persistent odors shortly after replacement, verify that the new filter is correctly seated and that the air purifier's top cover is securely closed. Ensure you are using a genuine Chuboor replacement filter.
