As hard water flows over them, the beads latch onto the hardness minerals and let go of a little bit of salt. The result? Silky, soft water that feels like a spa day for your whole house.

Note: Your water won’t taste salty, promise. The amount of sodium added is tiny—less than what you’d find in a slice of bread.

The system flushes itself with a strong brine solution (salty water) to strip off all the captured minerals and recharge the beads. It’s like the machine taking a nap and a shower at the same time.
