Marketing InformationThe Zilmet® ActivFlo water conditioner is a whole house no-salt, no power, hard water conditioner. Inside the Activflo is a unique catalytic alloy made from a combination of semi-precious metals that react with the water. As water flows through the Activflo the natural conductivity of the water causes the metals to react, generating an electrical field on the surface. This imposes a catalytic action that causes calcium to form into an insoluble aragonite crystal. These crystals do not have the same bonding properties as calcium which means that they won't stick pipework, heating elements, faucets and more.
