The per-buyer recommendations below say who each one suits.

Who should buy which

Pick the Kind Water Systems E-3000 Whole House Filter + Salt-Free Softener if

City-water homes that want softer, chlorine-reduced water at every tap without the salt hauling, brine refills, or water waste of a traditional ion-exchange softener.

Skip if

You have well water with iron or hydrogen sulfide, or you need true scale removal and measurable grain-capacity softening, which salt-free conditioning does not provide.

Pick the Waterdrop WHR01 (WD-WHR01A 32,000 grains, WD-WHR01B 48,000 grains, WD-WHR01C 64,000 grains) if

Households with an indoor spot near a floor drain, an installer or plumber lined up and room for a whole house filter ahead of the softener, who want a two tank salt softener in a 32,000, 48,000 or 64,000 grain size and accept buying salt on an ongoing basis.

Skip if

You want installation in the price or a published flow rate before sizing a system; you need an NSF/ANSI 44 listed softener; the install site is outdoors or far from a drain; or you may return it after opening, since this product's FAQ charges up to 50% of the price on an opened, connected unit.
