GE vs Whirlpool Water Softeners

Quick verdict

Pick GE if you want a known price, phone alerts and a published salt-efficiency figure; the GXSH45W is the more complete package for city water. Pick Whirlpool's WHES40 if your well has dissolved iron between 3 and 10 ppm, because its stated iron rating is more than three times the GE's, and its plumbing connection takes pipe up to 1-1/4".

Neither brand covers a large household well. Both top out at 45,000 grains or less, and both keep full parts coverage short. If that rules them out, the last section of this page points to systems built for bigger loads.

Side by side

GE also sells the 35,000-grain GXSH35W ($699), the older 40,000-grain GXSH40V ($569) and GXSHC40N ($656), and the Profile PNPR45W ($1,599), all as of October 2026. Whirlpool's softeners are made under license by Water Channel Partners.

Capacity and performance

Grains. GE's 45,000-grain GXSH45W edges the 40,000-grain WHES40. At 10 gpg, both suit three or four people; neither reaches the 48,000 to 64,000 grains a family of five or six usually needs. Use our sizing guide to run your own numbers.

Hardness. GE rates the GXSH45W to 165 gpg and Whirlpool rates the WHES40 to 125 gpg. Both are far above the 10.5 gpg where water is classed as very hard, so this rarely decides it.

Iron. This is Whirlpool's clearest win. The WHES40 is rated for 10 ppm of clear-water iron against 3 ppm for the GXSH45W. GE's older GXSH40V and GXSHC40N are rated for 8 ppm. Red or orange iron, iron bacteria and sulfur odor need a dedicated filter with either brand.

Flow and plumbing. GE publishes a 9.5 gpm service flow (15 psi drop). Whirlpool publishes no flow figure but its WHES40 valve fits plumbing up to 1-1/4", which matters in homes with larger supply lines.

Upkeep and running costs

Salt use. GE is the only one of the two that publishes an efficiency rating, 5,090 grains removed per lb of salt on the GXSH45W. For four people at 10 gpg that works out to roughly 215 lb, or five or six 40-lb bags a year, at $5 to $10 a bag. Whirlpool publishes no comparable figure, so its salt use can't be estimated from the maker's data. Whirlpool advises against block salt; use pellets or solar crystals in either unit.

Refills. The GE's hopper holds 230 lb of salt, enough for months of use in a typical home.

Cleanser. Whirlpool's five-year warranty depends on buying and using its softener cleanser, a recurring cost to factor in. GE's warranty has no such condition.

Smart monitoring. GE's SmartHQ app reports flow, flags leaks, reminds you about salt and has a vacation mode; a remote shutoff valve (RMVALVESFT) is sold separately. The Whirlpool product pages list no app or Wi-Fi features for these two models.

Price and warranty

GE lists the GXSH45W at $799 as of October 2026. Whirlpool does not publish a price for the WHES30 or WHES40 on its product pages. Budget roughly $200 to $1,000 extra if a plumber installs either one; see our cost guide.

Warranty: GE covers the whole appliance for one year, the electronic monitor for three and the resin tank for ten. Whirlpool starts at one year and extends to five with registration and regular cleanser use. Whirlpool's PRO models can reach ten years on the same terms.

Which should you choose?

Match the brand to your home

When to look beyond both. If you have five or more people, iron above 10 ppm or any red-water iron, or you want a control valve covered for many years, both brands fall short on published specs. Our best whole-house softeners include sizes to 64,000 grains with longer valve warranties. For wells, start with our best softeners for well water, and for heavy iron or rotten-egg odor, our iron and sulfur picks pair softeners with dedicated filters. The overall rankings place the WHES40 at #7 and the GXSH45W at #8. Full single-brand detail is in our GE review and Whirlpool review.
