How CitraCharge Technology Works
Unlike traditional salt-based softeners that remove minerals through ion exchange, NuvoH2O's CitraCharge technology uses food-grade citric acid to:
Bind to hard water minerals: Citric acid chelates calcium and magnesium, preventing them from forming scale
Keep minerals in solution: Hard water minerals stay dissolved and flow through your plumbing harmlessly
Break down existing scale: Gradually removes mineral deposits already built up in pipes and appliances
Preserve healthy minerals: Retains beneficial minerals for drinking water
The result: soft water that prevents scale buildup without salt, wastewater, or the slimy feel of traditional softeners.
