Product Description
Maintain peak water heater performance and extend its lifespan with the NuvoH2O Water Heater System Replacement Cartridge. This salt-free, citrus-based cartridge prevents hard water scale buildup while actively removing existing deposits, restoring your water heater to near-new efficiency and saving you money on energy and maintenance costs.
Prevents & Removes Hard Water Scale
Hard water scale is the silent killer of water heaters, reducing efficiency by up to 30% and shortening lifespan by years. The NuvoH2O replacement cartridge uses proprietary CitraCharge® technology to prevent new scale formation while actively dissolving existing buildup inside your water heater tank and on heating elements. This dual-action approach restores efficiency, reduces energy costs, and extends the life of your critical appliance.
Salt-Free CitraCharge® Technology
Unlike traditional salt-based water softeners that require constant maintenance and produce wastewater, the NuvoH2O system uses a revolutionary citrus-based formula that bonds to hard water minerals, preventing them from forming scale. This eco-friendly approach keeps beneficial minerals in your water while protecting your water heater from damaging deposits—all without salt, electricity, or wastewater.
Engineered for Easy Maintenance
The NuvoH2O cartridge features a compact, integrated design with quick-connect fittings and a self-locking mechanism that ensures leak-proof installation in seconds. No tools, no mess, no complicated procedures—just twist off the old cartridge and twist on the new one. It's the easiest water heater protection system you'll ever maintain.

How It Works
The NuvoH2O cartridge treats water as it enters your water heater, using CitraCharge® to condition hard water minerals before they can form scale. The citrus-based formula lowers pH to neutral levels, preventing scale adhesion while actively chelating existing deposits. Over time, you'll notice improved water heater performance, faster recovery, and lower energy consumption as scale dissolves and efficiency returns.
