Method: Covers residential point-of-use reverse osmosis drinking-water systems sold at a published US price, including under-sink (pressurized-tank), tankless under-sink, and plug-in countertop units. Excludes whole-house RO, commercial/industrial RO, and non-RO filters (pitcher, carbon-only, UF-only). Price is typical US MSRP in USD. installType is one of under-sink, tankless-under-sink, or countertop. filtrationStages is the manufacturer-stated number of filtration stages (integer count). ratedCapacityGpd is rated permeate production in gallons per day (GPD). pureToDrainRatio is the pure-water-to-wastewater ratio written X:1 (higher X = more efficient; a value below 1:1 wastes more than it makes). tdsReductionPct is the manufacturer-claimed total-dissolved-solids reduction as a percent. remineralization is a boolean: true if the system adds minerals or alkaline pH back to permeate. requiresElectricity is a boolean: true for pump-driven or countertop units that must be plugged in, false for gravity/line-pressure units. storageTankGal is usable clean-water storage in gallons (pressurized tank or countertop reservoir); 0 for pure on-demand tankless systems. nsfCertifiedStandards lists the NSF/ANSI standards the unit is third-party certified to (e.g. "58, 53, 42"), or "none" if uncertified. membraneLifeMonths is the manufacturer-rated RO membrane replacement interval in months. annualFilterCostUsd is the typical yearly replacement-filter cost in USD. Values are null if not disclosed by the manufacturer.
