3. Operating Instructions: Filter Indicator Reset
The YIOU Air Purifier R1 features a filter indicator to remind you when a filter replacement may be necessary. This indicator is typically represented by blinking SLEEP and ON/OFF buttons.
Resetting the Filter Indicator:
- If the filter indicator (blinking SLEEP and ON/OFF buttons) is active, it suggests the filter may need replacement.
- If you have replaced the filter, or if you determine that the current filter is still effectively maintaining air quality, you can reset the indicator.
- To reset, press and hold both the SLEEP and ON/OFF buttons simultaneously until the device emits three beeps. This action will clear the filter replacement reminder.

4. Maintenance
Regular maintenance of your filter ensures continuous optimal performance of your air purifier.
- Filter Lifespan: The lifespan of the filter depends on usage and air quality. The filter indicator serves as a guide.
- Visual Inspection: Periodically inspect the filter for visible dirt or discoloration. A heavily soiled filter should be replaced regardless of the indicator status.
- Cleaning: The pre-filter component can be gently vacuumed to extend its life, but the HEPA and activated carbon layers are not washable and must be replaced.
- Genuine Filters: Always use original YIOU replacement filters to ensure compatibility and maintain the air purifier's performance and warranty.
5. Troubleshooting
Filter Indicator Blinking:
- Symptom: The SLEEP and ON/OFF buttons are blinking.
- Cause: This indicates that the filter may need to be replaced.
- Solution: Replace the filter if necessary. After replacement, or if the filter is still effective, reset the indicator by pressing and holding the SLEEP and ON/OFF buttons until the device beeps three times.
