Brondell Circle vs. Waterdrop G3P800: Tankless RO Comparison
Brondell Circle RC100 ($300--$400) vs. Waterdrop G3P800 ($350--$500): both are tankless under-sink RO systems with smart filter monitoring. Key differences: Circle uses a 1:1 waste ratio; G3P800 uses 1:1 to 2:1 depending on inlet pressure and TDS. Circle produces 75 GPD; G3P800 produces 800 GPD rated (more than any household can consume). Circle's 2-cartridge design is simpler to maintain; G3P800's 3-cartridge design provides more pre-filtration stages for chloramine-heavy water. For households focused on water efficiency (low waste ratio) and clean design, the Circle is the better choice. For households who want maximum available GPD, the G3P800 wins.
