Quick Answer: For most families of three or more, the GE GXSHC40N is the better buy. It has more capacity (40,000 vs. about 34,900 grains), a higher flow rating, and phone alerts for low salt and possible leaks. The Morton MSD34C System Saver makes sense for a couple or a small home with moderate hardness that wants a basic, no-app softener. Neither model had an in-stock Amazon listing when we last checked. GE's current Smart Water Softener 35,000 grain keeps the Wi-Fi and flow alerts but lands at roughly the Morton's capacity. If you're on chlorinated city water and want resin that holds up to chlorine, also look at the DuraWater Fleck 5600SXT 32k with 10% resin.

Most people comparing these two think they're choosing a brand. They're really choosing a size. GE's model is a 40,000-grain softener with Wi-Fi. Morton's is a 34,000-grain softener without it. Once you know how many grains your household removes per day, the choice usually makes itself.

Start here: a 60-second decision
- One or two people, hardness under about 15 gpg? Morton is enough. You won't use the extra capacity in the GE, and you don't need an app to remind you about salt.
- Three to five people, or hardness over 15 gpg? GE. The bigger resin bed means fewer regenerations at a sensible salt setting.
- Over 110 gpg, or more than 8 to 9 ppm of iron? Neither. Both top out at 110 gpg. GE lists 8 ppm of clear-water iron and Morton lists 9 ppm, and running near those limits is asking for fouled resin.
- You want leak alerts, or the house sits empty for weeks? GE, because Morton's System Saver has no connectivity.
The numbers, from each brand's own documents
GE's figures come from its spec page for the GXSHC40N. Morton's come from its owner's manual for the M34 System Saver, the 34,000-grain model sold on Amazon as the MSD34C.
| GE GXSHC40N | Morton M34 / MSD34C | |
|---|---|---|
| Capacity | 40,000 grains | 13,700 @ 2.7 lb salt; 29,200 @ 8.6 lb; 34,900 @ 14.5 lb |
| Max hardness | 110 gpg | 110 gpg |
| Max clear-water iron | 8 ppm | 9 ppm |
| Rated service flow | 9.5 gpm (15 psi drop) | 7.8 gpm |
| Rated efficiency | 5,100 grains per lb of salt | 5,060 grains per lb at 2.7 lb dose |
| Resin tank | 9 x 40 in., 1.1 cu ft | 9 x 35 in. |
| Salt storage | 230 lb | Not stated in the manual |
| Regeneration | Demand-initiated, 94–134 min. | Demand-initiated, default 2 a.m. |
| Connectivity | Wi-Fi, Alexa, flow alerts, salt tracking | Low-salt light only |
| Certification | Not shown on GE's spec page | NSF/ANSI 44 and 372 |
| Warranty | 1-year parts and labor (see written terms) | 10 years on tanks; 1 year on other parts; labor not covered |
Two of those lines deserve a closer look: capacity and efficiency.
What "34,000 vs 40,000" actually means at your salt setting
Rated capacity is measured at the maximum salt dose, and almost nobody should run a softener there. That's the point of our explainer on what grain capacity really means. Morton's manual is helpful because it lists all three settings:
- At 2.7 lb of salt, the Morton removes 13,700 grains. That's the most efficient setting, about 5,060 grains per pound.
- At 8.6 lb, it removes 29,200 grains.
- At 14.5 lb, it removes 34,900 grains, but each extra pound is doing far less work.
Now run a real household through it. Two people at 12 gpg use about 2 × 75 × 12 = 1,800 grains a day. On the middle setting, the Morton goes over two weeks between regenerations. That's plenty. You could even drop to a lower salt dose and still regenerate only weekly.
Four people at 18 gpg is a different story: 5,400 grains a day. On the Morton's middle setting, that's a regeneration every five days or so, and you'll feel tempted to crank the salt up to stretch it. The GE has more resin to work with, so the same family gets more days per cycle at a moderate salt setting. If you're unsure where to set either one, our guide to setting the salt dose walks through it.
Salt and water: close enough not to decide it
The efficiency ratings are nearly identical: 5,100 grains per pound for GE and 5,060 for Morton. Over a year that's a rounding error. Morton's manual also lists 2.3 gallons of regeneration water per 1,000 grains removed at the minimum salt dose, which is in line with other units in this class. If you want to estimate your own yearly totals, see how much salt a softener uses and how much water regeneration uses.
Both units also have an optional salt-efficiency setting. Morton describes it as running at 4,000 grains per pound or better, and it's required in California. Expect more frequent regenerations when it's on.
What actually changes your salt bill is sizing. An undersized Morton in a big household will burn more salt than a GE running comfortably at a mid setting.
Flow: the difference you notice in the shower
GE rates the GXSHC40N at 9.5 gpm. Morton rates the M34 at 7.8 gpm. Below about 6 or 7 gpm of real demand, you won't notice either. That covers one shower plus a faucet, or a dishwasher and a sink. Run two showers and a washing machine together and the Morton is closer to its limit. If your house has three bathrooms, that alone tips it to GE.
GE's valve accepts plumbing up to 1-1/4 inch. It ships with 3/4-inch quick-connect fittings, and 1-inch pipe needs extra fittings. Measure before you buy.
The Morton's quiet advantages
It isn't all one-sided. The Morton is the simpler machine, with fewer things to go wrong and nothing to connect. Its manual has "Recharge Now" and "Recharge Tonight" buttons, adjustable backwash and fast-rinse times, a low-salt light you can calibrate (0 to 8), and settings that survive a power outage, though you may need to reset the clock.
Its warranty is longer on the parts most likely to fail catastrophically. Morton covers the salt tank and fiberglass mineral tank for 10 years against rust, corrosion, leaks and bursting. Other parts get one year. Labor isn't covered, but defective parts ship free. GE's spec page lists a one-year parts-and-labor warranty for the entire appliance and refers you to the written warranty for anything beyond that.
And Morton's manual states NSF/ANSI 44 testing for hardness reduction and efficiency, plus NSF/ANSI 372. GE's spec page for the GXSHC40N doesn't list a certification.
The GE's advantages, beyond size
GE's app features are genuinely useful in a few situations. A water-flow alert can catch a running toilet or a leak when you're away. With an external shutoff valve added, you can turn the water off remotely. Salt-use tracking tells you whether your setting is reasonable. All of it needs Wi-Fi at the softener, so check the signal in your utility room before you count on it.
GE also lists a built-in sediment filter, a "Salt Saver" button and an audible alarm. The 230 lb salt tank means fewer bag runs for a big family.
Fitting it into your utility room
GE lists the GXSHC40N at about 22.4 inches deep, 47.6 inches tall and 14.4 inches wide, with a net weight of 102 pounds before you add salt. It runs on a 24-volt transformer, so you need an outlet within reach. Morton's manual gives a 9 x 35-inch resin tank, which makes the System Saver a slightly shorter cabinet, but check the dimensions printed on your box before planning a tight closet install.
Both need the same three things nearby: a drain that can take the regeneration flow, an outlet, and room to lift a 40-pound bag over the lid. If you're squeezing a softener under a staircase, the lid clearance is what people forget. The Morton keeps its settings through a power outage, though you may need to reset the clock. Leave the GE's Wi-Fi disconnected and it still softens. You just lose the alerts.
GE's newer 35,000-grain model narrows the gap
If you go shopping for the GE now, the listing you'll find is the GE Smart Water Softener, 35,000 grain. It keeps what made the GE interesting: built-in Wi-Fi, SmartHQ app alerts for low, medium or high continuous water flow, low-salt reminders, and the option to add GE's RMVALVESFT shutoff valve for remote whole-house shutoff when a leak is detected. It has 1-inch plumbing connections with dual O-ring seals, quick connectors that accommodate 3/4-inch and 1-1/4-inch plumbing, and a bypass blending valve for setting how soft you want the water.
What it doesn't keep is the size advantage. At 35,000 grains it's roughly the Morton's rated capacity, so the "bigger family, buy GE" logic above no longer holds on capacity alone. Choose it for the app and leak alerts, not for fewer regenerations. GE's listing doesn't publish a service flow or certification for this model, so don't assume the GXSHC40N figures in the table carry over. Stock on it was limited when we checked.
When to skip both
If you're on chlorinated city water and want resin that holds up to chlorine, take a look at the DuraWater Fleck 5600SXT 32,000-grain. It uses 10% crosslink resin (1.0 cu ft, pre-loaded in a 9 x 48-inch tank), which is more durable than standard resin, on a metered Fleck 5600SXT valve. The package includes a 14 x 36-inch brine tank with float and a 1-inch bypass. It's the right size for the same small household that would otherwise buy the Morton, and Fleck parts are easy to find. The trade-off is that it arrives as more of a DIY project than a box-store unit, with no app and no published NSF certification on the listing.
Bottom line by household
- Couple or single person, 5–15 gpg: Morton MSD34C. Simple, certified, long tank warranty.
- Family of 3–5, or 15+ gpg: GE GXSHC40N. More capacity, more flow, and alerts you'll actually use.
- You want GE's app and leak alerts and can live with ~35k grains: GE Smart Water Softener 35,000 grain.
- Small household on chlorinated city water: DuraWater Fleck 5600SXT 32k.
Availability on both the GE GXSHC40N and the Morton MSD34C changes often, so check local home stores too.
