First, test your water hardness. You can buy a simple test strip or call your local water company—they love sharing this info. Anything above 7 grains per gallon means you’re a prime candidate for softening.
Next, think about your budget. Salt-based systems are the cheapest upfront, but salt costs add up. Salt-free ones cost more initially but save you from buying bags of salt forever. Math time, friend.
Also, consider your home’s size. A system for a studio apartment won’t cut it for a four-bedroom house. Check the grain capacity—it’s not a cereal rating, but it tells you how much hardness the system can handle before regenerating.
