Waterdrop tankless reverse osmosis system G3P800 — 800 GPD, 10-stage filtration, smart faucet

The Waterdrop G3P800 is a tankless, 10-stage reverse osmosis water filter that delivers up to 800 gallons per day of purified drinking water with a 3:1 pure-to-drain ratio and an integrated smart faucet.

Designed for households that need high volumes of clean water without the bulk of a storage tank, the G3P800 combines certified filtration stages with a compact, under-sink, tankless layout and a smart faucet that reports water quality. Third-party testing and multiple NSF/ANSI certifications back the system’s ability to reduce common contaminants while keeping lead-free materials and efficient water flow at the forefront.

How does the G3P800 remove contaminants from tap water?

The system uses a 10-stage filtration process centered on a reverse osmosis membrane that removes dissolved solids and many microscopic contaminants. Independent lab testing shows it targets PFAS, fluoride, heavy metals, and a range of organic compounds.

• 10-stage filtration including pre- and post-filters plus RO membrane
• Reduces PFAS, fluoride, lead, chromium, nitrates, and chlorine taste/odor
• Third-party laboratory (SGS) testing and NSF/ANSI 42, 53, 58, 372 certifications

What performance can I expect day-to-day?

The G3P800 produces up to 800 gallons per day and dispenses water quickly, filtering about one cup in roughly five seconds. As a tankless system it provides continuous supply without the wait for a storage reservoir to refill.

• 800 GPD capacity suitable for large families or frequent use
• Fast dispensing: ~5 seconds per cup
• 3:1 pure-to-drain ratio for improved water efficiency compared to traditional RO

What smart or convenience features are included?

The package includes a smart faucet with an LED indicator that shows TDS levels and general water quality at a glance. The LED has a long rated lifespan and activates automatically when water is flowing, helping you monitor performance without extra gadgets.

• Smart faucet displays TDS/water quality information
• LED indicator auto-activates with water flow; long-rated lifespan
• Tankless design saves under-sink space and removes need for periodic tank maintenance

How does certification and material safety support product reliability?

Multiple certified standards confirm both filtration effectiveness and material safety. The G3P800 meets NSF/ANSI standards for reducing total dissolved solids, chlorine, taste and odor, and uses lead-free components where required.

• NSF/ANSI 58 certified for TDS reduction
• NSF/ANSI 42 and 53 certified for chlorine, taste, odor, and contaminant reduction
• NSF/ANSI 372 certification verifies lead-free materials

Who is this for: The Waterdrop G3P800 is aimed at households, small businesses, or anyone needing a high-output, space-saving reverse osmosis solution. It’s especially useful where quick dispensing and continuous supply are priorities, and for buyers who want certified contaminant reduction plus a compact, modern under-sink installation without a storage tank.
