How CitraCharge® Technology Works
Unlike traditional salt-based water softeners that use ion exchange, NuvoH2O's CitraCharge® technology uses citric acid to chelate (bind to) hard water minerals like calcium and magnesium. This process prevents these minerals from forming scale deposits on surfaces while keeping them in the water for health benefits. The result is scale-free plumbing and appliances without the environmental impact or maintenance of salt-based systems.
