SpringWell WSSF-1 vs WSSS1: Salt-Free Conditioner or Salt-Based Softener Combo?

Specs verified 2026-10-05 from manufacturer pages and retailer listings. We have not lab-tested either system.

Both of these SpringWell combos start with the same WS1 air-injection iron filter for iron, manganese and sulfur. The difference is the second tank. The WSSF-1 pairs it with the FutureSoft FS1, a salt-free conditioner that uses template-assisted crystallization to keep hardness minerals from forming scale. The WSSS1 pairs it with the SS1, a 32,000-grain ion-exchange softener that removes the calcium and magnesium from the water.

SpringWell sells both as whole-well packages at a combo discount, both carry the same lifetime warranty and the same 6-month return window for unused, uninstalled items, and both require SpringWell's $134.25 well water test before the order ships. Choosing between them is really choosing between conditioning and softening, with plumbing and salt as the secondary costs.

What each one treats

The iron filter side is identical: SpringWell lists both combos as reducing iron, sulfur and manganese, with orange and black staining and odor as the symptoms addressed, across pH 6.5 to 10 on the iron tank. Nothing in either package treats bacteria, and neither carries a third-party certification; SpringWell states none for either combo.

The WSSF-1's conditioner does not remove hardness minerals. It converts them into suspended crystals so they are less likely to stick to pipes and heaters, and SpringWell says it prevents up to 95% of scale buildup, a maker claim with no third-party certification stated. A hardness test on the treated water will still read hard, and the conditioner's working range is narrower, pH 7.0 to 9.5. The WSSS1's softener removes hardness minerals by ion exchange with 32,000 grains of capacity between regenerations, which is what gives you spot-free glass and soft-feeling water; SpringWell's combo page lists water spots and scale as the symptoms it addresses.

Flow rate and sizing

The WSSF-1 keeps the full 12 GPM of the iron filter because the FS1 conditioner is also rated 12 GPM; the WSSF-4 size pairs a 20 GPM iron filter with a 15 GPM conditioner. The conditioner tank is small, 6 x 35 in. (39 in. with the head), beside the 10 x 54 in. iron tank, and the operating range is 20 to 80 psi.

The WSSS1 is limited by the softener: the iron filter is 12 GPM but the SS1 softener is 11 GPM, so the combo is rated at the lower figure, and the WSSS4 pairs a 20 GPM iron filter with a 13 GPM softener. It also takes more floor: a 9 x 48 in. softener tank (57 in. with the head) plus an 18 x 33 in. round brine tank next to the iron filter. For a one- to three-bathroom house either flow works; the extra GPM and the smaller footprint are the WSSF-1's practical edge.

One caution on the published shipping weight: both combo listings show 133 lb, which matches the WS1 alone and may not include the second tank.

Warranty, certifications and support

The terms are the same for both: a manufacturer's lifetime warranty against defects on tanks, media, fittings, valves and heads, with electronic heads limited to 5 years per the product pages (7 per SpringWell's warranty page), and returns accepted within 6 months only for unused, uninstalled items, with a 10% restocking fee. The WSSS1 has two electronic heads, one on each tank, so that limit applies twice; the WSSF-1's conditioner has no head or electronics to limit.

Media life differs. SpringWell gives the iron filter media 10+ years in both combos and the conditioner media 3 to 5+ years on the combo page (the standalone FS page says 5+). The softener's resin is covered by the lifetime media warranty. Neither combo states an NSF/ANSI certification, and the 95% scale-prevention figure on the conditioner is a maker claim.

Price, install and running cost

The WSSF-1 was $3,213.00 at springwellwater.com as of Oct 2026 (sale; regular $3,780.00), a $567 saving against the two units' regular list prices. The WSSS1 was $3,123.75 at springwellwater.com as of Oct 2026 (sale; regular $3,675.00, or $3,803.75 bought separately), a $680 combo saving per the product page. The salt-based combo is the cheaper one up front by about $89, and both add the $134.25 test and bypass valves ($58.79 to $78.74) plus an $83.99 installation connector on the WSSS1.

Install and upkeep favor the WSSF-1. Its iron filter needs a drain and power, but the conditioner needs no salt, drain, backwash, regeneration or electricity. The WSSS1 needs two drain lines, two power connections and regular salt refills, with metered regeneration to keep salt and water use down. Over the years the WSSF-1's only recurring item is conditioner media every 3 to 5+ years, while the WSSS1 adds salt and backwash water for as long as it runs.

Verdict

If the goal is to protect the water heater and plumbing from scale and you can live with water that still tests hard, the WSSF-1 is the better combo: it keeps the full 12 GPM, fits in less space, needs no salt or second drain, and ranks third on our list for exactly that simplicity. If you want genuinely soft water, for laundry, showers, spot-free dishes or because your hardness is high, only the WSSS1 removes the minerals; it costs about $89 less at the sale prices, but you pay it back in salt, water and a second drain and outlet, and its 11 GPM rating is the lower of the two. Both carry the same lifetime warranty and the same iron filter, so the decision is entirely about what you want the second tank to do.

Both systems have full spec pages: SpringWell WSSF-1 Well Water Filter + Salt-Free Conditioner Combo and SpringWell WSSS1 Well Water Filter + Salt-Based Softener Combo. For the wider field, see the ranked list, and size either one against your flow with the sizing guide.

Frequently asked questions

Does the WSSF-1 soften water?

No. Its FutureSoft conditioner uses template-assisted crystallization to reduce scale (up to 95%, a maker claim) but does not remove hardness minerals, so treated water still tests hard. The WSSS1's 32,000-grain softener removes calcium and magnesium by ion exchange.

Which combo is cheaper?

The WSSS1, by about $89 at the Oct 2026 sale prices: $3,123.75 against $3,213.00 at springwellwater.com. The WSSS1 then adds salt, backwash water and a second drain and power connection; the WSSF-1's conditioner needs none of those.

Why is the WSSS1 rated 11 GPM when the iron filter is 12?

The combo takes the lower rating of its two tanks. The WS1 iron filter is 12 GPM but the SS1 softener is 11 GPM. The WSSF-1's conditioner is rated 12 GPM, so that combo keeps the full 12.

Does either combo need a drain and power?

Both do for the iron filter, which backwashes to drain and has an electronic head. The WSSS1's softener needs a second drain line and power supply; the WSSF-1's conditioner needs neither.
