Frequently Asked Questions
How do I choose the right water purification method for my needs?
The best purification system depends on your lifestyle, space, and water quality. At Optimal Hydration, we offer two advanced solutions: the OH-1 Desktop Plug & Play System, perfect for flexible living arrangements, and the OH-2 Under-Counter System, ideal for a permanent installation. Both deliver clean, great-tasting, hydrogen-rich water through multi-stage reverse osmosis and UV sterilisation. To help you decide, explore our guide: Choosing the Right Hydrogen-Rich Water System for You.
Are minerals in water beneficial?
Yes. Essential minerals such as magnesium, calcium, and potassium play a vital role in supporting energy, hydration, digestion, and recovery. That’s why we developed OH-E+ Natural Electrolytes, a blend of ionic fulvic acid and trace minerals that are highly bioavailable and free from additives. This ensures your body absorbs the minerals quickly and effectively, enhancing the health benefits of purified water.
How often should I replace my filter and how do I know?
For optimal performance, we recommend replacing your OH-1 system filter every 12 months, depending on your local water quality. Our filters are designed with a smart twist-out cartridge system, allowing for quick and simple replacement—no engineer visits or complex dismantling required. To make maintenance effortless, you can also sign up for our annual filter subscription service, ensuring your system always delivers the highest-quality water.
Do water filters remove all contaminants from tap water?
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.
Can water purification remove microplastics?
Yes. Reverse osmosis (RO) is one of the most effective methods for removing microplastics thanks to its ultra-fine filtration capabilities. All Optimal Hydration purification systems use advanced RO technology to help ensure your water is free from microplastics, along with other impurities, pollutants, and pathogens.
Do I still need purified water if my area has “safe” tap water?
Even in regions where tap water meets regulatory safety standards, it can still contain trace pollutants, chlorine, microplastics, or pathogens. Purifying your water ensures the highest quality for daily hydration. Our hydrogen-rich purification systems not only remove impurities but also add molecular hydrogen, which supports antioxidant activity, reduces oxidative stress, and promotes recovery and overall wellness.
