Quick Answer: Whirlpool’s three current softeners cover most households from a single-brand, big-box channel. The WHES40E (40,000 grains, 8.5 GPM, roughly $750-800) is the mainstream default for 1-6 person homes. The WHES44 (44,000 grains, 12 GPM, roughly $800-900) adds a meaningfully higher flow rate and 6th Sense usage-learning for homes running more fixtures at once. The WHESFC (31,000 grains, roughly $900) trades some capacity for a built-in whole-house filter that also cuts chlorine taste and odor. All three use demand-initiated regeneration and are NSF certified — the real choice is flow rate and whether you want filtration bundled in.
Whirlpool is one of the few national appliance brands that also sells a complete water softener lineup, and it shows up constantly across this site as the default “mainstream, plug-and-play” alternative to a Fleck-based build — our best water softener pillar recommends the WHES40E for exactly that buyer, and the WHES44 appears in our best whole-house water softener roundup. This review pulls those three models together and breaks down which one actually fits your household, instead of just naming one as a runner-up.
Whirlpool lineup at a glance
| Model | Best for | Capacity | Flow rate | Iron removal | Price |
|---|---|---|---|---|---|
| Whirlpool WHES40E | Best overall / mainstream | 40,000 grain | 8.5 GPM | 10 ppm | ~$750-800 |
| Whirlpool WHES44 | Best flow rate / larger household | 44,000 grain | 12 GPM | 10 ppm | ~$800-900 |
| Whirlpool WHESFC | Best hybrid softener + filter | 31,000 grain | — | 3 ppm | ~$900 |
1. Whirlpool WHES40E — Best Overall / Mainstream
The WHES40E is the softener our best water softener pillar names as the easiest big-brand pick, and it earns that spot on specs alone: 40,000 grains rated for up to 125 grains per gallon of hardness, 10 ppm of clear-water (ferrous) iron removal, and an 8.5 GPM flow rate that covers a typical 1-6 person household running a shower and a washing machine at once without a noticeable pressure drop. It’s NSF certified, houses the resin and brine tanks in one cabinet to save floor space, and backs the unit with a 5-year limited warranty.
Whirlpool WHES40E 40,000 Grain Softener
- Demand-initiated regeneration meters actual water use instead of running on a fixed clock, so it only regenerates when the resin bed is genuinely close to exhausted.
- Single sealed cabinet houses both resin and brine tanks, cutting floor space by roughly 25% versus a traditional two-tank layout.
- Low-salt indicator light and simple onboard programming — no app required to keep it running correctly.
Salt is the one recurring cost every one of these models shares, and running out mid-cycle is the most common way a softener quietly stops actually softening — Amazon Prime ships 40-pound bags free in two days, and you can try it free for 30 days.
2. Whirlpool WHES44 — Best Flow Rate / Larger Household
Step up to the WHES44 and two things change: capacity climbs to 44,000 grains rated for up to 140 grains per gallon of hardness, and flow rate jumps to 12 GPM — the highest in Whirlpool’s residential lineup, and enough headroom for a home where a shower, a dishwasher, and an outdoor spigot might all draw at once without softened-water pressure sagging. It also adds Whirlpool’s 6th Sense technology, which tracks actual household water-use patterns over time and adjusts salt and water dosing accordingly, rather than sizing every regeneration the same way regardless of how much water you actually moved that week.
Whirlpool WHES44 44,000 Grain Softener
- 12 GPM flow rate is the highest in Whirlpool's current lineup, built for homes with more simultaneous fixture draws.
- 6th Sense usage-learning adjusts salt and water dosing to your household's real consumption pattern instead of a fixed default.
- Self-cleaning sediment filter is built in, so there's no separate pre-filter cartridge to buy or swap.
3. Whirlpool WHESFC — Best Hybrid Softener + Filter
The WHESFC trades some raw grain capacity — 31,000 grains versus 40,000+ on the other two — for a genuinely different feature: a built-in whole-house filter stage that reduces chlorine taste and odor alongside softening hardness, in the same cabinet, with no separate filter cartridges to change or replace. It’s rated for up to 120 grains per gallon of hardness and 3 ppm of iron, a lower iron ceiling than the WHES40E or WHES44, so it’s the wrong pick for well water with a meaningful iron load — pair it with a dedicated pretreatment stage instead, or see our best water softener for well water guide for iron-tolerant systems built for that job specifically. It carries a 2-year full parts-and-labor warranty, a 3-year electronics warranty, and a 10-year tank warranty.
Whirlpool WHESFC Hybrid Softener + Filter
- Combines softening and whole-house filtration in a single unit — no separate filter housing or cartridge changes.
- Uses up to 25% less salt and water than older Whirlpool models by only regenerating based on monitored usage.
- Best matched to municipal or low-iron well water — the 3 ppm iron rating is the tradeoff for the built-in filter stage.
Where Whirlpool falls short of a Fleck build
The tradeoff across all three models is the same one we flag on every big-box cabinet unit: Whirlpool’s valve is proprietary to the WHES line, sold and serviced primarily through Whirlpool’s own water-solutions channel and the retailers that carry it. A Fleck 5600SXT-based build uses a control valve manufactured continuously since the 1980s, with every wear part — O-rings, injectors, the piston — sold as a standardized component by dozens of independent suppliers. That means cheaper, faster parts sourcing on a 10-15+ year ownership timeline, at the cost of assembling a system yourself instead of buying one retail SKU with a national-brand warranty.
Who should actually buy Whirlpool
Whirlpool makes sense if you want a single sealed cabinet with a recognizable brand name, NSF certification, and mainstream retail support (Lowe’s, Whirlpool’s own site) rather than researching a Fleck-based builder like AFWFilters. The WHES40E covers most 1-6 person homes; step up to the WHES44 if more than two fixtures regularly run water at once; choose the WHESFC only if chlorine taste/odor is a real complaint in your house and your water isn’t carrying meaningful iron. It’s a weaker choice on heavy well-water iron (see our best water softener for well water picks) or if long-term parts availability matters more than one-stop convenience.
The bottom line
The Whirlpool WHES40E remains the right default for most households shopping a big-box brand — NSF certified, demand-initiated, and priced in line with our best water softener top picks. Step up to the WHES44 for the extra flow rate and usage-learning if your household runs more fixtures at once, or the WHESFC if bundled chlorine filtration matters more to you than maximum grain capacity. For the widest long-term parts network instead of a single retail SKU, our Fleck 5600SXT review is still the more rebuildable choice. Once it’s installed, our water softener maintenance guide covers the salt, brine tank, and resin schedule that keeps any of these three running for years.
