Waterdrop Reverse Osmosis Systems
The G3P600 is rated at 600 gallons per day and the G3P800 at 800, both with a smart faucet that shows TDS and filter life. Waterdrop lists NSF/ANSI 58 and 372 certifications for its G3 series.
Choosing a Waterdrop
- G3P600: 600 GPD, a good fit for most households filling glasses, bottles and pots.
- G3P800: 800 GPD for larger households or faster flow, at a higher price.
- X series: higher-capacity models with additional features. Compare current specs.
- Waste ratio: check the pure-to-drain claim on the data sheet for each model.
- Filters: G3 systems use twist-off cartridges such as the G3-N3CB carbon block. Bundles with spares lower the cost of the first year.
- PFAS: only rely on PFOA/PFOS claims the certification listing supports.

FAQs
What is the difference between Waterdrop G3P600 and G3P800?
The main difference is output: the G3P600 is rated for 600 gallons per day and the G3P800 for 800. The G3P800 fills containers faster and suits larger households, while the G3P600 costs less. Both are tankless under-sink systems with a smart faucet and twist-off filters. Check each model's waste ratio and filter part numbers.
Is Waterdrop NSF certified?
Waterdrop states that its G3 tankless RO systems are certified to NSF/ANSI 58 and 372. Certification covers the specific contaminants and materials listed, so check the current certification listing or performance data sheet for the exact claims, such as PFOA/PFOS or lead reduction, before relying on them.
How often do you change Waterdrop RO filters?
Waterdrop typically rates the carbon block pre-filter for about 6 to 12 months and the RO membrane for about 2 years, depending on water quality and use. The smart faucet shows filter life. Use genuine part numbers matched to your model, such as the G3-N3CB for G3P600 and G3P800.
