Whirlpool Water: Understanding the Product Line
Whirlpool water filtration products come in three tiers: (1) Entry (WHER25 RO, GXWH40L-equivalent whole-home sediment): basic RO and prefilter products at Home Depot. (2) Mid-range (WHCF-DWHBB whole-home carbon filter): comprehensive whole-home carbon filtration. (3) Premium (Whirlpool WHES40E water softener): full ion-exchange softening. For most homeowners, the WHER25 under-sink RO is the most practical Whirlpool water product -- it provides the most contaminant reduction scope at the most visible point of use (kitchen faucet). Pairing with the appropriate EveryDrop refrigerator filter completes the kitchen water treatment picture without dealer involvement or professional installation for either component.
