There are many methods available to improve the quality of tap water, but advanced multi-stage purification offers the most reliable results. At Optimal Hydration, our OH-1 Desktop and OH-2 Under-Counter Purification Systems combine six-stage reverse osmosis with UV sterilisation and molecular hydrogen infusion. This process removes up to 99% of impurities and pollutants, neutralises pathogens, and delivers clean, great-tasting, hydrogen-rich water that also supports antioxidant activity and recovery.

Not all filters are created equal. Basic carbon filters typically reduce chlorine and improve taste but leave behind many contaminants. The Optimal Hydration OH-1 and OH-2 systems are engineered to remove up to 99% of impurities and pollutants, including heavy metals, chemicals, and pathogens, ensuring water that is both safe and refreshing.

Improving taste starts with removing the substances that cause odour, cloudiness, or chemical aftertastes. The OH-1 and OH-2 systems use high-efficiency reverse osmosis, UV sterilisation, and molecular hydrogen infusion to deliver crisp, clean water straight from your tap or tank. The result is consistently fresh-tasting water that encourages better hydration.

Filtered water is typically treated to reduce certain contaminants, such as chlorine or sediment, but it may still contain other pollutants. Purified water, by contrast, undergoes a much more rigorous process to eliminate up to 99% of contaminants and pathogens. Our OH-1 and OH-2 systems go beyond standard filtration by combining reverse osmosis, UV sterilisation, and hydrogen infusion to provide the highest level of purity. For a permanent installation, the OH-2 under-counter system is ideal, while the OH-1 desktop system offers a flexible, plug-and-play solution.
