SpringWell SS4 Salt Based Water Softener (48,000 grain) review
Salt-based water softener. Plumber recommended if you are not comfortable with this install. Skill and code, not a preference. No third-party certification on record. Claims below are manufacturer-reported.
What it removes
| Contaminant | Evidence | Stated reduction | Scope |
|---|---|---|---|
| Hardness (as CaCO3) | Manufacturer-reported | 99% | |
| Iron | Manufacturer-reported | 80% |
Certified is an NSF, WQA, or IAPMO listing for that claim. Manufacturer-reported reduction for iron. Not NSF-certified for iron.
Whole-house hardness at 7 gpg or more. Does not remove arsenic, nitrate, or fluoride.
