The World Health Organization says, "There does not appear to be any convincing evidence that water hardness causes adverse health effects in humans." Some studies have shown a weak inverse relationship between water hardness and cardiovascular disease in men, up to a level of 170 mg calcium carbonate per liter of water. Other studies have shown weak correlations between cardiovascular health and water hardness. The World Health Organization has reviewed the evidence and concluded the data were inadequate to allow for a recommendation for a level of hardness. In a review by the National Institute of Public Health in the Czech Republic gives a good overview of the topic, and unlike the WHO, it sets some recommendations for the maximum and minimum levels of calcium (40-80 mg/L) and magnesium (20-30 mg/L) in drinking water, and a total hardness expressed as the sum of the calcium and magnesium concentrations of 2-4 mmol/L.

2-6-2017 Believe it or not, hard water is the best source of calcium for most of the world. Milk has calcium but nutritionists do not consider it to be a primary source. Some veggies have calcium just because it's part of the soil, but still not as good a source as hard water. A water softener replaces calcium and magnesium with sodium, so the water is not fit to drink: it causes heart attacks.

Jewels Vern BTW you have to get your water tested and then make the tester answer all your questions. First, the water from your faucet is not necessarily identical to the water next door, second you need to learn the words, and third you are unlikely to find anybody else who actually knows what they are talking about. I have researched water filters for two years and most places won't even tell you if the filter they sell will fit the canister they sell. There are four different standard sizes, so that is a real problem.
