Extend the life of your plumbing, washing machine, dishwasher, water heater, and other appliances without adding excess salt waste, phosphates or other chemicals into the environment. With our Salt-Free Water Conditioner, water stains and spots are easier to wipe off. Aquasana’s SCM technology naturally and effectively inhibits scale buildup by transforming dissolved hard minerals into inactive microscopic crystal particles that are harmlessly passed through your water and down your drain. Plus, unlike salt-based water softeners, Aquasana's Salt-Free Water Conditioner won't demineralize your water. Experience delicious, salt free drinking water and no soap lather change in the shower or while doing dishes. Replacement conditioner for the following systems: WH-1010-CT-LM, WH-1010-CT-UV-LM, WH-1021-CT, WH-1021-CT-UV-LM, WH- WELL-CT-UV, WH-WELL-CT-UV-LM.
