Filtration Technology and Water Quality
You want to understand how the C100 delivers such exceptional water. This system uses an advanced 5-in-1 composite filter, providing a comprehensive approach to purification. It removes up to 95% of TDS and 99.9% of contaminants, ensuring you receive truly clean water.
The 6-Stage Purification Process
Your water undergoes a thorough journey through PP cotton, coconut shell activated carbon, an ultra-fine RO membrane, post-activated carbon, and UV sterilization. This multi-stage process effectively eliminates impurities, including dangerous lead, arsenic, fluoride, chlorine, and bacteria, protecting your health.
Remineralization and Alkaline pH Balancing
After purification, the C100 thoughtfully restores necessary minerals. The system remineralizes your water with calcium, magnesium, and potassium, which are often lost in reverse osmosis. This step ensures your drinking water is not only pure but also beneficial for your body.
You might worry about the demineralizing effect of standard reverse osmosis. The C100 addresses this concern directly through its integrated remineralization stage.

This thoughtful addition helps balance the pH, moving the water from slightly acidic, which can happen with RO, to a healthier alkaline state. You will notice a difference in taste and feel confident you are consuming water that supports your overall well-being, not just removes impurities.
