RO is ideal for situations where water quality is a major concern, such as in areas with contaminated water sources or for individuals with specific health concerns that require high-purity water. It's perfect for those seeking purified drinking water with the lowest levels of impurities.

• Removes: Bacteria, viruses, microorganisms
• How it works: UV sterilization uses ultraviolet light to destroy harmful microorganisms such as bacteria, viruses, and protozoa. The UV light penetrates the cell walls of these microbes, disrupting their DNA and rendering them harmless. This process is highly effective against waterborne pathogens and doesn’t involve the use of chemicals, making it an eco-friendly purification method.
• Best for: Biological contamination protection. UV sterilization is especially valuable in areas where biological contaminants are a concern, such as in water that may contain harmful pathogens. It’s an excellent option for those looking to ensure the microbiological safety of their drinking water, particularly in regions with poor water sanitation or natural water sources at risk of contamination.

Multi-Stage Systems

1. Pre-filter: Removes sediment and large particles
2. Carbon stage: Eliminates chlorine and chemicals
3. RO membrane: Filters out dissolved contaminants
4. Post-filter: Final polishing for taste
5. UV light: Kills any remaining microorganisms
