Zilmet ActivFlo Lite 3/4" FNPT Water Conditioner (ZAFL2234)

The Zilmet ActivFlo Lite is a premium salt-free water conditioner designed to protect tankless and traditional water heaters from scale buildup. Using a proven galvanic catalytic process, the ActivFlo Lite improves efficiency, extends equipment life, and reduces maintenance — all without salt, chemicals, electricity, or filter replacements. Perfect for homes with hard water and any property running a tankless water heater system.

Why Choose ActivFlo Lite?

  • 100% salt-free & maintenance-free — zero power, zero chemicals, zero ongoing cost
  • Protects tankless and tank water heaters from scale buildup and efficiency loss
  • Eco-friendly solution — keeps beneficial minerals without adding contaminants
  • Improves heater efficiency by reducing limescale on heat exchangers
  • Compact stainless steel body installs inline in minutes
  • Bi-directional design — easy installation in any direction
  • 12-year manufacturer warranty for long-term protection

How the ActivFlo Technology Works

Inside the stainless steel housing is a galvanic alloy element. As water flows through the chamber, hardness minerals such as calcium and magnesium are transformed into non-adhering aragonite crystals. This prevents them from bonding to pipes, fixtures, and heat exchangers — significantly reducing scale formation and helping remove existing deposits over time.

Ideal Applications

  • Tankless water heaters (Navien, Rinnai, Takagi, Noritz, Rheem, etc.)
  • Traditional tank water heaters
  • Homes with hard water scale issues
  • Rental properties requiring low-maintenance solutions
  • Point-of-use protection for appliances and fixtures
