- System type. Salt-based ion exchange is the most common. Dual tanks give soft water during regeneration and cost more.
- Capacity. Harder water and bigger households need a larger unit.
- Plumbing. A loop for the softener, a drain and an outlet near the main line make the install easy. Without them, it costs more.
- Upkeep. Salt and service add a running cost.
