Salt-free water softeners vs salt-based water softeners: pros and cons If you're deciding between salt-free and salt-based water softeners, here are the key benefits of going salt-free: No salt required: Salt-free systems don't require ongoing salt refills, saving you time and effort. Longer lifespan: Salt-free systems, like Springwell, can last up to 50 years, while salt-based systems typically last only 10-15 years. Environmental benefits: Salt-free systems don’t discharge salt into the environment, reducing their impact on water treatment plants and the ecosystem. No maintenance for drains or electricity: These systems don’t require drains, motors, or electrical outlets, making installation simpler and reducing maintenance needs. Water heater protection: Salt-free systems prevent the corrosion of water heaters that can occur with salt-based systems.
