2.1 Filtration Stages
The Thereye 1000 GPD system, which uses this RO filter element, employs an advanced 8-stage filtration process:
- Stage 1: PP Cotton
- Stage 2: 5 Micron Polypropylene Fabric
- Stage 3: Coconut Shell Activated Carbon
- Stage 4: Food Grade RO Antiscalant
- Stage 5: 1 Micron Polypropylene Fabric
- Stage 6: 0.0001 Micro RO Membrane (This product)
- Stage 7: Post Carbon Filter
- Stage 8: PP Cotton

4. Operating Instructions
4.1 Initial Flushing
After replacing the RO filter element, it is essential to flush the system to remove any air and carbon fines. Run water through the filtered water faucet for approximately 5-10 minutes, or until the water runs clear and free of air bubbles. Discard this initial flushed water.
4.2 Smart Display Faucet
The compatible Thereye system includes a smart display faucet that provides real-time information:
- TDS Monitor: Displays the Total Dissolved Solids (TDS) level of the filtered water, indicating water quality.
- Filter Lifespan Indicator: Provides reminders for timely filter replacements.

6. Troubleshooting
If you experience issues after replacing your RO filter element, consider the following:
- Low Water Flow: Ensure the new filter element is fully seated and locked. Check for any kinks in the water lines.
- Poor Water Quality (High TDS): Verify the RO filter element is correctly installed. Ensure the system was properly flushed after installation. If issues persist, the RO membrane may be faulty or the system may require professional inspection.
- Leaking: Confirm the filter element is securely twisted into its housing. Check O-rings for proper seating and damage.
For comprehensive system troubleshooting, consult the main instruction manual for your Thereye 1000 GPD Undersink Tankless Water Filter System or contact customer support.
