How much does a water softener cost in Illinois?

A professionally installed traditional salt-based softener runs $800–$2,000 depending on size and brand. A salt-free conditioner like the Trio system runs $1,200–$2,500 installed.

While the upfront cost is higher for salt-free, there's no ongoing salt cost (which runs $15–$30/month for traditional softeners) and no maintenance contract needed.

Most systems pay for themselves in reduced appliance wear and cleaning product savings within 3–5 years.
