1. Product Overview
The Doulton 10" Ultracarb Ceramic Water Filter is designed to provide clean, safe drinking water by effectively reducing various contaminants. This filter is compatible with Doulton undercounter systems (HIP Duo, HIP Trio, HIS & QT) and countertop systems (HCP & HCS).
At the core of this filter is the "Sterasyl" silver-impregnated ceramic microfilter, which works in conjunction with an activated carbon block to deliver comprehensive filtration.
Key Benefits:
- Reduces suspended solids, pathogenic bacteria, hydrogen sulphide, and lead.
- Reduces chlorine and improves the taste and odor of your water.
- NSF Certified for performance and material safety.

2. Setup and Installation
Proper installation is crucial for the filter's performance and longevity. Always refer to your specific Doulton system's manual for detailed installation instructions. The following are general guidelines for replacing or installing the Ultracarb filter candle.
- Preparation: Turn off the water supply to your filter system. Relieve any pressure in the system by opening a filtered water tap.
- Remove Old Filter (if applicable): Unscrew the housing sump and carefully remove the old filter candle. Dispose of the old filter responsibly.
- Clean System: Before installing the new cartridge, it is recommended to clean the filter housing. You may add a small amount of chlorine solution to the empty housing and let it sit for approximately 2 minutes to sanitize the system. Rinse thoroughly with clean water.
- Install New Filter: Carefully unwrap the new Doulton Ultracarb filter. Screw the filter candle into the filter head. Ensure it is hand-tightened securely but do not overtighten.
- Prevent Air Lock: To prevent air from impeding filtration, fill the filter housing (sump) with water before screwing it back onto the filter head. This helps to displace air and ensures immediate water flow.
- Reassemble and Check for Leaks: Screw the housing sump back onto the filter head. Slowly turn on the water supply and check for any leaks. Flush the system for a few minutes to remove any air and fine particles.

3. Operating Instructions
Once installed, the Doulton Ultracarb filter operates continuously as water passes through your compatible Doulton filtration system. No special operational steps are required beyond ensuring the water supply to the system is open.
The filter will reduce contaminants and improve water quality as it flows through the ceramic and carbon layers. You may notice a slight reduction in water flow compared to an unfiltered tap, which is normal and indicates the filter is working.
4. Maintenance
Regular maintenance ensures optimal performance and extends the life of your Doulton Ultracarb filter.
4.1. Cleaning the Filter Candle
The ceramic surface of the filter can be cleaned to restore flow rate and remove accumulated particles. This should typically be done every 5 weeks, or when you notice a significant reduction in water flow.
- Turn off the water supply and relieve system pressure as described in the installation section.
- Carefully remove the filter candle from its housing.
- Using a soft brush or a clean dish sponge (do not use soap or detergents), gently scrub the outer surface of the ceramic filter under running water. This will remove the trapped sediment and restore the flow rate.
- Important: Wear gloves during cleaning as the filter surface will contain trapped particles and bacteria. Ensure no contaminants from the cleaning process enter the internal parts of the filter or the clean side of the housing. If the filter was removed for cleaning, it is advisable to re-sanitize the housing as described in the installation steps.
- Reinstall the cleaned filter candle following the installation steps, including filling the housing with water to prevent airlock.
4.2. Filter Replacement
The Doulton Ultracarb filter candle should be replaced periodically to ensure continued contaminant reduction and optimal water quality. While cleaning can restore flow, the activated carbon inside has a finite lifespan for chemical reduction.
- Recommended Replacement Interval: Replace the filter candle approximately every 6 to 8 months, depending on water quality and usage.
- Indicator for Replacement: A noticeable and persistent reduction in water flow, even after cleaning, indicates that the filter's capacity is exhausted and it needs replacement.

5. Troubleshooting
Here are some common issues and their potential solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Reduced Water Flow | Filter surface clogged with sediment; Activated carbon exhausted. | Clean the ceramic filter surface as described in Section 4.1. If flow does not improve, replace the filter candle. |
| Water Tastes/Smells Bad | Filter is old or exhausted; Improper installation leading to bypass. | Replace the filter candle. Recheck installation to ensure all connections are secure and no water is bypassing the filter. |
| Leaking from System | Loose connections; Damaged O-rings; Cracked housing. | Ensure all connections are hand-tight. Check O-rings for damage and replace if necessary. Inspect housing for cracks. |
| Filter Arrived Damaged | Shipping damage. | Do not install. Contact your retailer or Doulton customer service immediately for a replacement. |
