NuvoH2O (Nuvo H2O) Water Softeners

NuvoH2O salt-free water softeners, from an authorized dealer

NuvoH2O (often written Nuvo H2O) conditions hard water with a citric-acid cartridge instead of salt and resin: no brine tank, no drain line, no electricity, and the healthy minerals stay in your water. It won't remove iron or bacteria and it isn't a filter — what it does is stop scale forming on fixtures, water heaters and appliances, which is what most city-water homeowners actually want from a softener. Aqua Home Supply is an authorized NuvoH2O dealer: Nuvo's own pricing with a price match if you find it lower, free shipping, and no sales tax outside Minnesota.

Which NuvoH2O system do I need?

NuvoH2O sizes by home square footage. The Home series is rated for homes of 1,500 sq. ft. or less (cartridge good for about 20,000 gallons); the Manor series is for homes over 1,500 sq. ft. (about 50,000 gallons per cartridge, 1″ connections). Add Duo if you also want a second filter stage — taste, sediment, iron or chloramine — and Trio if you need two.

Replacement cartridges by system

NuvoH2O says its customers replace cartridges about every six months on average water use. The system doesn't alert you, so set a calendar reminder when you install.
