For the Ionmax Compressor Dehumidifier Rhine Pro (ION651), we recommend regular cleaning of the pre-filter to keep the unit running efficiently:
Pre-Filter Cleaning
- Check and clean the pre-filter about every 2 weeks if you use the unit frequently.
- If your space is dustier (e.g., pets or heavy airborne particles), you may want to clean it more often.
- Always ensure the filter is completely dry before putting it back in.
- Never run the unit without the pre-filter installed, as dust build-up can affect performance and cause issues.
HEPA Filter Reminder
The unit also has a HEPA filter used for air purification, and the system tracks its usage time.
After about 1,500 hours of operation, filter replacement is required when the display reads HE.
In summary:
✅ Pre-filter: Clean every ~2 weeks (or more often in dusty conditions).
✅ HEPA filter: Replace when the indicator flashes (~1,500 hours of use).
