Water softener · 10 GPM · Treats hardness · $1,296 (sale) at US Water Systems as of Oct 2026

The US Water Systems Matrixx Smart Metered Water Softener is an ion-exchange softener built on 10% cross-linked resin, said to tolerate oxidants better than 8% resin. The base MXX-100 holds 1.0 cu ft and 35,000 grains at 10 GPM service and 12 GPM peak; the MXX-150 is 53,000 grains at 15 GPM and the MXX-200 70,000 grains at 20 GPM. US Water Systems itself notes a softener removes iron only in small amounts, so it is no substitute for an iron filter.

The Bluetooth valve programs from an app and keeps settings on battery backup; the maker claims up to 70% lower salt and water use. The media tank is 9 by 48 in., the brine tank holds 220 lb of salt, and connections are 1 in. or 3/4 in. MPT; the tech sheet gives an approximate shipping weight of 120 lb. Certifications are component-level: a WQA Gold Seal valve, NSF certified resin and an NSF/ANSI 61 compliant tank, with no system-level NSF/ANSI 44 listing.

Price was $1,295.95 at uswatersystems.com as of Oct 2026 (sale; regular $2,444.92). It is marketed for DIY with just five connections. Warranty is lifetime on tank and resin, 10 years on valve and electronics, plus the one-year money-back promise.

These are component-level statements. The owner's manual states: 'The above capacity and flow rate specifications have not been validated by the WQA.' WQA certified-product database (find.wqa.org/find-products) searched 2026-10-06 for 'US Water Systems', 'US Water', 'USWater', 'Matrixx' and 'MXX': no listing under US Water Systems or the Matrixx name, so no system-level NSF/ANSI 44 or WQA Gold Seal certification is recorded for the assembled softener. NSF certified-product database (info.nsf.org), searched 2026-10-06: No Matching Products Found for trade name "Matrixx". US Water Systems, Inc. (Plainfield, IN) has an NSF/ANSI 42 listing, but only for 22 filter cartridges (507-USWCB-...) as "COMPONENTS: Filter Cartridges[1] [Pb]" with "[1] Conforms to the material requirements only."; no Matrixx system, softener or spin-down appears.

Pros and cons

Pros

Lifetime tank and resin warranty plus 10 years on valve and electronics
10% cross-linked resin is more chlorine/oxidant tolerant than standard 8% resin
Three sizes up to 20 GPM / 70,000 grains

Cons

Maker itself says a softener removes iron only in small amounts; not a substitute for an iron filter on iron-bearing wells
Certifications are component-level (valve, resin, tank), not a system-level NSF/ANSI 44 listing
Overall height differs between US Water Systems' documents (54.375 in. in the manual, 56.5 in. on the tech sheet); the 120 lb weight is the tech sheet's approximate shipping weight

Our take

This is the softener to pair with an inFusion or another iron filter when the test shows hardness and you want app control and a long warranty on the resin itself. It costs less than the SpringWell SS1 and offers larger sizes up to 70,000 grains. The gap is certification: the dealer-sold Culligan and Kinetico softeners carry a system-level NSF/ANSI 44 listing, and this one does not.

Not sure it is the right size for your flow and your water test? Work through the sizing guide, or compare every system we cover on the best well water filtration systems (2026) list.
