How CitraCharge® Technology Works
Unlike traditional salt-based water softeners that use ion exchange, NuvoH2O's patented CitraCharge® technology uses food-grade citric acid to chelate (bind to) hard water minerals like calcium and magnesium.
The CitraCharge® process:
Binds to minerals: Citric acid chelates calcium and magnesium, preventing them from forming scale
Keeps minerals in solution: Hard water minerals stay dissolved and flow through your plumbing harmlessly
Prevents scale formation: Minerals can't adhere to surfaces or form deposits
Preserves healthy minerals: Retains beneficial minerals for drinking water and health
The result: scale-free plumbing and appliances without the environmental impact, maintenance hassles, or slippery feel of salt-based systems.
Advantages Over Traditional Salt-Based Softeners
No salt to buy or haul: Eliminate the hassle and expense of heavy salt bags
No electricity costs: Passive system saves energy and money
No wastewater discharge: Eco-friendly operation with zero environmental impact
No slippery feel: Soft water without the slimy residue of salt softeners
No sodium added: Better for your health, plants, and septic systems
Keeps essential minerals: Retains healthy calcium and magnesium
Low maintenance: Simple cartridge replacement every 6 months
