WHES40E 40,000 Grain Water Softener (NSF Certified)

The Whirlpool WHES40E is an NSF-certified 40,000-grain water softener with demand-initiated regeneration and salt- and water-saving technology — the mainstream, big-box answer for anyone nervous about softening their water for the first time. Softening at the source is the most durable fix for dense Asian hair abroad, where water much harder than Taipei or Seoul is what leaves thick hair dull, stiff and unresponsive to every product. Being metered, it regenerates on demand rather than on a timer, so it only spends salt and water when you actually draw. The NSF certification and a trusted brand name make it a reassuring anchor for a first-time softener buyer; step up to a 48,000-grain or larger unit instead if you have a very large home or especially hard water.
