The 49-System Database at a Glance
The System Finder filters our research database of 49 whole-house water treatment systems by your water source (city or well), the problem you are treating, your bathroom count and flow rate, and your budget. Every system in the database is tracked with its published equipment price, replacement filter and media schedule, certifications on file, and an estimated 10-year cost of ownership: equipment plus the replacement filters and media the manufacturer schedules over ten years, at published prices. Estimates are ranges because street prices and replacement intervals vary. Pricing and specifications were last verified in October 2026. We do not run a lab and we do not claim hands-on testing — every figure below traces to a manufacturer specification, a certification listing, or a published price. The full method is on our System Finder methodology page.
