Aquasure Harmony Series AS-HS48D 48,000 Grain Water Softener 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 | not stated |
Certified is an NSF, WQA, or IAPMO listing for that claim.
Whole-house hardness at 7 gpg or more. Does not remove arsenic, nitrate, or fluoride.
1.5 cu ft resin; a value pick for 3-5 people at 15-20 gpg well water or larger city-water households. Aquasure sells a 64k AS-HS64D ($749.99 direct) for 6+ bathrooms but no live base Amazon listing was found for it. Program tested hardness plus iron compensation; add sediment prefilter on well water.
