How we checked
The Waterdrop manufacturer product page identifies the exact model as "Waterdrop Reverse Osmosis Hot Cold Water Dispenser, A1" (model A1) at a regular price of $649.00 (on sale for $529.00), and its Specification table states 100GPD capacity, 2:1 pure-to-drain, 7-stage filtration, "NSF/ANSI 372 Certified", and "Electricity Required: Yes"; the compare table gives A1 an average annual filter cost of $129.97 and 12-month A1-RO filter life. The AquaHome Supply retailer page corroborates the same unit (Model WD-A1, UPC 840814179963) as a countertop, corded-electric system with 100-gallon capacity and a 2:1 drain ratio. Note: the retailer and the manufacturer's own FAQ describe it as "6-stage" filtration while the manufacturer's Specification table says "7-stage"; the authoritative manufacturer spec-table value (7) was used, and TDS-reduction percent and gallon storage are left blank because neither is stated verbatim.
