In short

The Active Shield is Varsity Water Systems' complete salt-free scale inhibitor: a specialized media blend that deactivates hardness minerals, filters chlorine taste and odor, and uses IonTech media to reduce bacteria growth inside the tank. It inhibits scale without removing hardness minerals, which is exactly the job it is sold for. Three Rivers installs it across the Greater Pittsburgh area.

When you need powerful, salt-free scale prevention, The Active Shield is Varsity Water's complete on-demand protection. With a specialized blend of media, it's capable of deactivating hardness minerals, improving the smell and taste of water, and preventing bacteria growth inside the tank. The Active Shield takes a proactive approach to protect your home from limescale and chlorine, while stopping bacteria in its tracks.

  • Scale Reduction Media: Crystallin-assisted technology alters the state of calcium and magnesium hardness minerals to prevent its damaging capabilities. [wording as published by Varsity]

  • IonTech Media: Actively reduces bacteria growth inside the tank.

Why choose The Active Shield

Low Maintenance IonTech Bacteria Protection Eco-Friendly, Salt Free System Made in the USA

Salt-free means scale inhibition, not softening: the minerals stay in the water, conditioned so they are far less likely to stick. If you want hardness actually removed, that is a softener's job. See the softener vs. scale inhibitor FAQ.
