Protection Right Where You Need It.

Protect a water heater, dishwasher, ice machine or RV without installing a whole home system. Each compact solution brings CitraCharge™ scale protection directly to the appliance or application that needs it.

The Same CitraCharge™ Protection in a More Focused Solution.

Each system treats water just before it reaches the appliance. CitraCharge™ keeps minerals from forming scale and helps reduce existing buildup without salt or electricity.

Water runs along a supply line and scale builds up inside it. A Targeted Solution filter on the line treats the water, the minerals stay sealed, and the protected appliance is shown: a water heater, a dishwasher, an ice machine or an RV.

Tankless Water Heater

Help Your Tankless Water Heater Perform Its Best

Scale can build up on heating elements, making your tankless water heater work harder. Independent testing conducted with Battelle Memorial Institute found that NuvoH2O prevented more than 98% of scale buildup and helped electric tankless heaters reach full temperature more than 25% faster.

  • 98% scale buildup prevented
  • 25% faster to full temperature

Dishwasher

Fewer Spots. Less Scale.

The Dishwasher System helps prevent scale inside your machine and reduces the spots and film left on dishes and glassware. Prefer a solution with no installation? Dishwasher Scale Preventer Pucks go directly in the machine and last up to three months.

Simple Scale Protection. No Installation Needed.

Use Scale Preventer Pucks in your toilet, dishwasher or evaporative cooler for up to three months of protection. For a quick boost, add a CitraCharge™ Booster Pack to your dishwasher for three to four washes, or mix it in a spray bottle for targeted spot treatment.
