Above 7 grains per gallon is where scale damage and soap-scum complaints become noticeable. Below 5 gpg most homes do fine without one. Does softened water taste salty? No. Ion exchange swaps calcium and magnesium for a small amount of sodium, about 30 mg per 8 oz glass at 10 gpg hardness, which is well below the taste threshold. Is salt-free conditioning the same as softening? No. Salt-free TAC systems change the calcium so it cannot stick to surfaces, but the hardness is still chemically present. Soap will lather better than untreated water but not as well as truly softened water. How much salt does a softener use? A typical family of four uses one 40 lb bag per month, or about $5 to $15 in salt depending on type and region. ## Keep reading - [Best water softeners →](/best-water-softeners) - [Salt-based vs salt-free softeners →](/buying-guides/salt-based-vs-salt-free-softeners) ## More explainers - [ Is Chloramine Safe to Drink? 4 min read ](/learn/is-chloramine-safe-to-drink) - [ How Often Should You Replace a Whole-House Water Filter? 4 min read ](/learn/how-often-replace-whole-house-filter) - [ What Are PFAS in Drinking Water, and Should You Worry? 5 min read ](/learn/what-is-pfas-in-drinking-water) - [ Well Water vs City Water: True Cost Over 10 Years 5 min read ](/learn/well-water-vs-city-water-cost) Whole House Water Treatment Independent, U.S.-focused reviews and water-quality guides for whole-house filters, softeners and reverse osmosis systems.
