How to Decide
Ecowater’s ERO375 is a compact under‑sink reverse‑osmosis system that homeowners use for pure drinking water. The alternatives split into a few clear camps: APEC’s ROES‑100 leans on a high 100‑gallon‑per‑day capacity for larger families; AquaPure’s AP‑3000 emphasizes a tankless design with ultra‑low 5 W power draw; Waterdrop’s G3P800 stands out for its 800‑gallon‑per‑day output while remaining tankless; iSpring’s RCC7 is chosen for its built‑in 3‑gallon pressurized storage tank.
When comparing these systems, focus on (1) daily output capacity – ranging from 75 gpd to 800 gpd – which determines how well the unit meets household demand; (2) storage architecture – tankless models save cabinet space but rely on instant flow, whereas tank‑based units provide a reserve for peak use; (3) power consumption – only AquaPure specifies a sub‑5 W draw, relevant for energy‑conscious homes; and (4) filter‑replacement ecosystem – availability and cost of spare filters vary, affecting long‑term ownership expenses.
