Whirlpool Water Softeners: NSF 44 Certified at Lowe's
Whirlpool (Benton Harbor, Michigan) markets water softeners through Lowe's under the same brand name as its washing machines and dishwashers. The WHES30E and WHES40E are NSF 44 certified for hardness reduction and sold as direct competition to GE at Home Depot and WaterBoss on the adjacent Lowe's aisle. Whirlpool softeners are OEM-manufactured by EcoWater Systems (a Pentair company) — the same parent that produces WaterBoss.
Whirlpool Softener Lineup
| Model | Grain Capacity | Demand-Initiated | Price (~) |
|---|---|---|---|
| WHES30E | 30,000 grains | Yes (metered) | $480–$600 |
| WHES40E | 40,000 grains | Yes (metered) | $580–$720 |
| WHESFC Pro+ | 60,000 grains | Yes (metered) | $800–$1,100 |
Whirlpool WHES40E: The Most Versatile Mid-Range Choice
The WHES40E is the Whirlpool model that most consistently earns "best pick" placement in water softener reviews. At 40,000 grains of capacity, it handles the majority of US residential applications — families of 2–4 with hardness up to 30 GPG — without the grain-capacity risk that undersized 30,000-grain units carry. The WHESFC Pro+ at 60,000 grains is overkill for most single-family homes but appropriate for large households (6+) or very hard water above 30 GPG.
