The Biggest Myth About RO Water
A common concern people have before buying an RO purifier is: "Doesn't it remove all the good minerals from the water?"
The short answer is: Older RO systems did, but modern ones do not!
How Modern ROs Keep You Healthy:
Today's advanced RO purifiers use two brilliant technologies to ensure your water is both safe and nutritious:
- TDS Controllers: Instead of dropping the TDS to zero, a TDS controller blends a small amount of ultra-filtered (UF) water back into the RO water. This safely retains natural minerals like Calcium and Magnesium.
- Mineralizer Cartridges: Many premium purifiers include a final "Mineral/Alkaline Cartridge." After the water is purified, it passes through natural mineral stones, adding back essential nutrients and balancing the pH level.
Our technicians expertly tune your TDS controller to the perfect healthy level. Enjoy pure water without losing out on nutrition!
