Zilmet ZAF010 ActivFlo House Water Conditioner

Reduce limescale throughout the home—without salt, power, or backwash. The Zilmet ActivFlo (MPN ZAF010) uses a catalytic alloy to condition hard water so minerals form less-adhesive crystals, helping protect water heaters, fixtures, and appliances. Compact and maintenance-free, this 1″ inline unit is sized for typical whole-home flows and installs in minutes on the cold water main.

Save Water & Energy (No Salt, No Power)

With no brine tanks, regeneration cycles, or electrical hookup, ActivFlo helps keep heat exchangers and aerators cleaner so equipment runs closer to design efficiency—without ongoing salt purchases or a drain connection.

Everyday Performance You Can See

As water passes the catalytic alloy, calcium is encouraged to form non-adherent aragonite crystals instead of hard scale. That means less buildup on showerheads, faucets, and heater components in typical household use.

Durable Stainless Construction

A stainless steel housing protects the internal element and stands up to mechanical-room environments. ZAF010 is a compact 6″ body with 1″ male NPT ends for straightforward service access and long-term reliability.

Installer-Friendly Inline Design

Standard 1″ MNPT threads make retrofits simple at the point of entry. Follow the installation manual’s arrow for flow direction and provide unions for future service. Typical whole-home operating flows fall in the 1.9–5.9 GPM range.

Sized Right For Whole-Home Use

ZAF010 is commonly selected for 1″ services on small to mid-size homes. For higher demand or larger mains, consider high-flow ActivFlo variants; for individual fixtures or appliances, see ActivFlo Solo point-of-use models.

Low-Upkeep Protection

With no media to replace and no backwash cycle, routine maintenance is minimal—just periodic visual checks during regular plumbing service. The long 15-year warranty underscores low total cost of ownership.
