2. Safety Information
- Always handle filters with clean hands.
- Do not use with water that is microbiologically unsafe or of unknown quality without adequate disinfection before or after the system.
- Ensure all connections are secure to prevent leaks.
- Keep out of reach of children.
- Dispose of used filters according to local regulations.
3. Product Overview
PHOENIX GRAVITY Carbon Filter Cartridges are engineered for efficient water purification. They are constructed from coconut shell-based carbon, which is safe for drinking water systems and does not release harmful chemicals. These filters are designed to reduce chlorine, lead, and other contaminants while retaining beneficial minerals naturally present in water.
Key Features:
- Efficient Filtration: Effectively removes chlorine and impurities for improved taste and odor.
- Mineral Retention: Filters water without removing naturally occurring minerals vital for health.
- Durable Design: Each pair of filters can process up to 20,000 liters of water.
- Material: Made from natural coconut shell activated carbon.

Filtration Process:
- Stage 1: Tortuous Path: Activated carbon creates a complex path that captures impurities, ensuring water clarity.
- Stage 2: Sterilizing: Impregnated silver effectively eliminates mold, contributing to consistently fresh and safe drinking water.

4. Setup and Installation
Follow these steps to install your PHOENIX GRAVITY Carbon Filter Cartridges into your gravity-fed water filter system.
4.1. Priming the Filters
Before first use, it is essential to prime the filters to ensure proper function and remove any carbon dust.
- Unpack the new filter cartridges.
- Hold each filter under cold running water for several minutes, allowing water to flow through the filter. Gently scrub the exterior with a clean brush or cloth to remove any loose carbon dust.
- Fill a container with water and submerge the filters completely for at least 15-20 minutes to allow them to fully saturate. This helps prevent air pockets and ensures optimal flow.
4.2. Installation into the System
- Ensure your gravity water filter system's upper chamber is clean and empty.
- Insert the threaded stem of each primed filter into the holes in the base of the upper chamber.
- Secure the filters in place using the provided wing nuts or washers from the underside of the upper chamber, ensuring a snug fit but do not overtighten.
- Place the upper chamber onto the lower collection chamber.

5. Operating Instructions
Once installed, your PHOENIX GRAVITY Carbon Filter Cartridges are ready for use.
- Pour untreated water into the upper chamber of your gravity filter system.
- Allow the water to slowly pass through the carbon filters into the lower collection chamber. This process may take some time, depending on the water level and filter condition.
- Collect the filtered water from the spigot of the lower chamber.
- Always ensure there is water in the upper chamber for continuous filtration, but avoid overfilling.
5.1. Testing Filter Performance (Optional)
To verify filter performance, you can conduct a simple turmeric test:
- Add 1 tablespoon of turmeric powder to water in a mixing container and stir thoroughly.
- Pour this mixture into the upper chamber of your gravity water filter.
- Observe the water collected in the lower chamber. If the filters are working correctly, the collected water should be clear, with no turmeric color, taste, or odor.
6. Maintenance
Regular maintenance ensures optimal performance and longevity of your PHOENIX GRAVITY Carbon Filter Cartridges.
6.1. Cleaning
- Periodically remove the filters from the upper chamber.
- Gently scrub the exterior of the filters under cold running water with a clean, soft brush or cloth to remove any accumulated sediment.
- Do not use soap or detergents, as these can damage the filter material.
- Rinse thoroughly before re-installing.
6.2. Filter Replacement
The PHOENIX GRAVITY Carbon Filter Cartridges are designed to filter up to 20,000 liters per pair. For optimal performance and water quality, it is recommended to replace the filters every 6-12 months, or sooner if you notice a significant decrease in flow rate or a change in water taste/odor.

7. Troubleshooting
If you encounter issues with your PHOENIX GRAVITY Carbon Filter Cartridges, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Slow flow rate | Filters are clogged with sediment; filters not properly primed; airlock. | Remove and clean filters by scrubbing the exterior. Re-prime filters by submerging them in water. Ensure wing nuts are not overtightened. |
| Unpleasant taste or odor in filtered water | Filters have reached end of life; filters not properly primed; water source issue. | Perform the turmeric test to check filter efficacy. If filters are old, replace them. Ensure filters were primed correctly. |
| Water leaking from connections | Wing nuts are loose; washers are missing or damaged. | Tighten wing nuts securely (do not overtighten). Check that all washers are in place and undamaged. Replace if necessary. |
