The Zilmet ActivFlo Water Conditioner is a Whole House No-Salt Hard Water Conditioner.  It imposes a catalytic action as water flows that causes calcium to form into an insoluable aragonite crystal.  These crystals do not have the same bonding properties as calcium which means that they won't stick to pipework, heating elements, faucets, glassware, countertops, etc.
