What it does for your water

The NuvoH2O HHP-2516 Salt-Free Conditioner and Filter System is a conditioner and filter combo.

Salt-free systems don't remove calcium or magnesium, so the water won't feel softer and a hardness test will read the same. Makers describe them as reducing scale.

Questions buyers ask

Does the NuvoH2O HHP-2516 Salt-Free Conditioner and Filter System soften water?
No. It is designed to reduce scale, not to remove the calcium and magnesium that make water hard, so a hardness test reads the same after it.
