You need a softener if your showerhead looks like it’s been dusted with flour, your dishes have cloudy spots, and your hair feels stiff after washing. This is the silent hero of appliance longevity. Your water heater and washing machine will thank you for decades.
There’s a cultural angle here. In the American Midwest and Southwest, water is famously hard—almost a regional identity. Travel to certain parts of the UK, and you’ll find kettles furred with limescale within weeks. A softener is practically a rite of passage in these areas.

Practical tip: If you’re on a low-sodium diet, look for a potassium chloride softener instead of salt-based ones. They cost a bit more but are much kinder to your blood pressure. Your heart can sip happily.
