What 37 mg/L means at home
Soap and shampoo lather with very little product. Kettles and showerheads stay mostly free of white crust.
Some people notice that soap feels slow to rinse off in soft water. That slippery feel is normal and harmless.
Hardness is not a health problem, and EPA sets no limit for it. It is a matter of scale and soap.
What to do about it
Nothing, as far as hardness goes. At 37 mg/L a softener would have almost nothing to remove.
Carbon filter
If the water tastes of chlorine, a pitcher or faucet carbon filter takes care of that. It does not change hardness.
