Water Softeners Without Salt

How Our No-salt System Works

Tank 1

Step A

The water treatment process starts in tank #1, where, your water is treated with our KDF filter media, designed to enhance the performance of the activated carbon, remove heavy metals and protect the carbon bed from bacterial growth.

Step B

Next in tank #1, harmful impurities are removed or reduced using our NSF certified Catalytic coconut shell activated carbon to provide filtered water from every faucet in your home.

Removes or Treats:

Tank 2

The final water treatment process occurs in tank #2, where our special “anti-scale” filter media prevents hard water scale formation by forming Nano Crystals, which travel with the flow and do not stick to surfaces.
