What's the difference between water softening and water purification systems?

Water softeners remove mineral ions like calcium and magnesium causing hardness, improving soap effectiveness and reducing limescale. Purification systems eliminate contaminants, bacteria, and chemicals for drinking safety. Softeners address aesthetic issues; purification ensures health protection. Many properties benefit from combining both systems for comprehensive water quality improvement.

What should I check before hiring a water treatment systems provider?
