Its innovative ceramic filter eliminates a wide range of contaminants while retaining essential minerals for optimal hydration.
Advanced filtration for crystal-clear water
This purification system uses a high-performance ceramic cartridge, capable of processing up to 5,000 liters of water while removing viruses, bacteria, heavy metals, chemicals, pesticides, and microplastics. Thanks to its multi-layer structure, it guarantees great-tasting filtered water, perfect for everyday drinking, cooking, or washing food.
An eco-friendly and economical choice
By choosing the Coldstream MAX, you’re opting for a solution that’s both sustainable and environmentally friendly. This filtration system helps significantly reduce the use of single-use plastic bottles, thereby contributing to the reduction of plastic waste. In addition, it operates without electricity, providing a cost-effective and eco-responsible alternative while lowering your energy consumption. Thanks to its robust design and the use of high-quality materials such as recyclable PET plastic, this filter ensures enhanced durability, reducing the need for frequent replacements and delivering pure water at a lower long-term cost.
Filtration Technology
The Coldstream MAX uses an innovative ceramic cartridge designed to provide maximum protection against a wide spectrum of contaminants while preserving the water’s essential minerals.
Triple protection barrier:
- Activated carbon core: removes chemicals, chlorine, and heavy metals
- Inner white ceramic layer: blocks bacteria, microplastics, and fine particles
- Outer blue ceramic layer: provides antimicrobial protection and captures viruses and other pollutants
Contaminants removed:
✔ Bacteria (E. coli, Legionella, Pseudomonas)
✔ Viruses (Norovirus, Rotavirus)
✔ Heavy metals (lead, mercury, chromium VI, iron)
✔ Chemicals (chlorine, chloramine, THM, VOC)
✔ Pharmaceutical residues
✔ Pesticides and herbicides
✔ Microplastics and fine particles

Installation Instructions
Installing the Coldstream MAX Undercounter system requires no major plumbing modifications, but it should be handled by someone familiar with basic plumbing procedures.
Required Tools and Materials
- Adjustable wrench
- Phillips screwdriver
- Pipe cutter for plastic tubing
- Push-fit connectors 3/8" and 1/2" BSP
- PTFE tape (if needed to prevent leaks)
- Container to collect residual water
Installation Steps
1. Preparation and Safety
- Unpack all components and familiarize yourself with their arrangement.
- Make sure you have all the necessary plumbing fittings to complete the installation.
- Ensure your hands are clean before handling the filter and connections.
- Shut off the cold water supply feeding the existing faucet.
- Open the faucet to release any remaining water pressure in the pipes.
2. Installing the T-Connector
- Place a container under the cold-water line to catch any residual water.
- Cut the cold-water line that feeds the existing faucet.
- Install the T-connector to supply the new filtration system.
- Use push-fit connectors to attach the T-connector to the pipes.
- Apply PTFE tape to the threaded fittings if necessary to prevent leaks.
3. Installing the Filter Housing
- Mount the wall bracket for the filter housing under the sink using the provided screws.
- Secure the filter head to the bracket with the four Phillips screws.
- Tighten the base of the housing with the provided wrench to ensure a proper seal.
4. Connecting the Tubes
- Cut the 3/8" plastic tubing into two lengths suitable for your setup.
- Connect the first tube:
- One side into the push-fit outlet of the T-connector.
- The other side into the filter housing inlet.
- Connect the second tube:
- One side into the filter housing outlet.
- The other side into the inlet of the dedicated filtered water faucet.
5. Verification and Commissioning
- Close the T-connector and restore the main cold-water supply.
- Gradually open the T-connector and check for any leaks.
- Open the filtered water faucet to release trapped air from the system.
- Let the water run for 5 minutes to flush out any carbon particles from the first use.
- Check the flow rate of the filtered water.
Maintenance & Replacement
Filter Maintenance and Replacement
When to Replace the Filter?
- Every 5 to 6 months, depending on water quality.
- When the water flow rate decreases significantly.
- When the filter color changes from blue to white.
Replacing the Cartridge
- Wash your hands thoroughly before handling the filter.
- Turn off the cold-water supply and open the filtered water faucet to release pressure.
- Unscrew the filter housing using the provided wrench.
- Empty residual water from the housing and carefully remove the old cartridge.
- Ensure the black seals from the old filter are removed.
- Install the new cartridge, placing the supplied seals on each end.
- Replace and tighten the housing using the wrench.
- Turn the water back on and let it run for 5 minutes before use.
Cleaning the Filter to Extend Its Lifespan
- Disconnect and remove the cartridge from the housing.
- Clean the outside of the filter under cold water using a clean scouring pad (no soap or chemicals).
- Ensure no water enters the outlet hole of the filter.
- Reinstall the cleaned cartridge into the housing and tighten the assembly.
- Test the filtered water flow to ensure proper operation.
To ensure optimal performance, follow these recommendations:
✔ Cartridge cleaning: When the water flow slows down, remove the cartridge and clean the outer surface under cold water using a scouring sponge (no soap).
✔ Replacement indicator: After each cleaning, the blue layer gradually fades. Once the white ceramic becomes visible, it’s time to replace the cartridge.
✔ Lifespan: Up to 5,000 liters or a maximum of 12 months, or when the white ceramic becomes visible.
✔ Do not exceed one year of use, even if the water flow remains good.
