Our verdict on the Waterdrop G2P600
The Waterdrop G2P600 is a 600 GPD tankless under-sink reverse osmosis system whose only certification we could find is IAPMO R&T file WC-13977 to NSF/ANSI 372 — a limit on lead in the unit's own materials, not a tested contaminant-reduction claim — with no listing found in the NSF or WQA directories as of 2026-09-03. It fits municipal-water households that can supply an under-sink power outlet and drill two holes, and not well-water homes or anyone who cannot drill.[1][2][3][4][5]
Best for
- Municipal-water households wanting high-output under-sink RO: Waterdrop rates the G2P600 at 600 GPD with a 0.42 gpm draw and tags it for 4-6 person families
- Kitchens with a spare under-sink power outlet, a sink deck or countertop that can take one drilled hole for the RO faucet, and a drain line that can be tapped
- Buyers whose priority is lead-free wetted materials, which is what IAPMO R&T file WC-13977 actually certifies to NSF/ANSI 372
- Buyers who want a tankless unit: IAPMO lists it as plumbed-in to a separate tap without a reservoir, so it takes no storage tank under the sink
Not for
- Well-water homes without pre-treatment — Waterdrop does not recommend well water as the feed and asks that it first pass a spin-down sediment or whole-house filter
- Renters and anyone who cannot drill: installation needs two permanent holes, one for the RO faucet and one for the drain-line connection
- Under-sink cabinets with no power outlet, since the system will not run without mains electricity
- Buyers who need certified contaminant-reduction performance, which the NSF/ANSI 372 listing does not cover and which no directory listing we found supports for this model
- Anyone wanting mineralized or alkaline output — Waterdrop's own G-series table marks Alkaline Mineralization with an x for the G2P600

What the Waterdrop G2P600 does not do
IAPMO R&T's listing for this model certifies the lead content of the unit's own materials, not its ability to reduce anything from water: file WC-13977 covers NSF/ANSI 372 and carries no contaminant-reduction claim.

The Waterdrop G2P600 against its family and its rivals
The Waterdrop G2P600 has 4 siblings in its family: G3P600, G3P800, WD-G2-W, G5P500.
IAPMO R&T file WC-13977, issued to Qingdao Ecopure Filter Co. Ltd, lists the G2P600 (WD-G2P600-W) together with the 400 GPD WD-G2-W, the WD-G2MNR-W, and the WD-G2CF, WD-G2MRO and WD-G2P6MRO cartridges, all under NSF/ANSI 372 for the lead content of wetted materials. That file carries no contaminant-reduction claim for any of them, so it cannot be read as certifying what any G2-series unit removes from water. Waterdrop's own comparison table credits the sibling G3P600 with NSF/ANSI 42, 58 and 372, which is a broader scope than anything we found listed for the G2P600.[1][2]

The rest of the family
| Model | What differs |
|---|---|
| G3P600 | Same 600 GPD output and 2:1 drain ratio, but an 8-stage train, a smart display faucet showing TDS and filter life instead of a mechanical faucet, and a higher price. |
| G3P800 | 800 GPD instead of 600 GPD, a 3:1 pure-to-drain rate against the G2P600's 2:1, and a 10-stage train with a smart display faucet showing TDS and filter life. Waterdrop publishes two conflicting item weights for the G3P800 on its own product page, so no weight comparison is stated here. |
| WD-G2-W | 400 GPD instead of 600 GPD. Shares the WD-G2CF pre-filter but uses the WD-G2MRO membrane cartridge, which is not interchangeable with the G2P600's WD-G2P6MRO. |
| G5P500 | 500 GPD instead of 600 GPD, a 7-stage train, and a shorter 24-month membrane cycle split across G5P500-CF and G5P500-RO cartridges. |
Waterdrop G2P600 questions, answered
Is the Waterdrop G2P600 NSF certified?
Verified health claim
Not by NSF. The only listing we found for this model is IAPMO R&T file WC-13977, which certifies Waterdrop WD-G2P600-W to NSF/ANSI 372 — a limit on how much lead the unit's wetted materials may contain, verified as a weighted average of no more than 0.25%. IAPMO R&T is an equivalent certifier to NSF and certifies to the same NSF/ANSI standards, so this is a real third-party certification; it simply is not a contaminant-reduction certification. Searching NSF's Drinking Water Treatment Units directory, NSF's Drinking Water System Components directory and the WQA listings for this model returned no listing on 2026-09-03. Waterdrop's own marketing phrase 'NSF/ANSI 372 Certified' is therefore accurate but describes the materials, not the filtration.
What contaminants does the Waterdrop G2P600 actually remove?
Verified health claim
Waterdrop claims the 7-stage system reduces PFOA, PFOS, lead, arsenic, fluoride, chromium VI, nitrates, cadmium, TDS, chlorine, rust, sediment and others, and that is a manufacturer claim rather than a certified one. No certifier listing we found tests or confirms any of those reductions for this model: the IAPMO R&T listing covers lead content of materials under NSF/ANSI 372 only, and no NSF or WQA listing was found as of 2026-09-03. Reverse osmosis as a technology is well established for these contaminants, but for this specific model the reduction figures rest on Waterdrop's own testing.
What is the difference between the Waterdrop G2 and the G2P600?
They are two different systems, not two names for one. The G2P600 is rated 600 GPD and the plain G2 is rated 400 GPD, and they sell under separate Amazon listings (B08746M1NX and B082CZ9XZ9). They share the WD-G2CF pre-filter, but the membrane cartridge differs: the G2P600 takes the WD-G2P6MRO and the G2 takes the WD-G2MRO, so the cartridges are not interchangeable. Both appear on the same IAPMO R&T lead-free-materials file. This matters when ordering replacements, because Google's own results blend the two model names.
How long do Waterdrop G2P600 filters last?
Waterdrop rates the WD-G2CF composite pre-filter for up to 12 months or 1,100 gallons and the WD-G2P6MRO membrane filter for 24 months or 3,300 gallons. At Waterdrop's own prices of $29.99 and $99.99 as of 2026-09-03, that works out to about $79.99 a year in cartridges. The system has filter life indicators that prompt a change, and the indicator must be reset after each replacement or it stays red.
Can the Waterdrop G2P600 be used on well water?
Verified health claim
Waterdrop does not recommend it. Its own FAQ states that well water is not recommended as a source because of its complicated composition, and that anyone feeding the system from a well should first pass the water through a spin-down sediment filter or a whole-house filter system. Owners on wells report the cartridges themselves are marked to be fed with municipal tap water only, and that Waterdrop makes no well-water version of them. Untreated well water can also carry bacteria, which nothing in this system's certification addresses.
Does the Waterdrop G2P600 need electricity and a drain connection?
Yes to both, and it also needs two holes drilled. Waterdrop states the system requires under-sink electricity, and advises preparing a separate outlet if the one shared with a garbage disposal or dishwasher does not work. Installation requires drilling two holes: one for the dedicated RO faucet and one for the drain-line connection. The system cannot be plumbed into an existing kitchen faucet or onto the main supply pipe, so a sink deck or countertop with no spare hole has to be drilled.
Sources: [1]
Does the Waterdrop G2P600 add minerals back to the water?
Verified health claim
No. Waterdrop's own G-series comparison table marks Alkaline Mineralization with an x for the G2P600, alongside the G3P600 and G5P500. Waterdrop sells a separate 'G2P600 Remineralization' system for buyers who want minerals added back, and an owner who fitted Waterdrop's remineralization cartridge to a standard G2P600 reported a post-filter pH of about 9.3 against 7.8 from their tap. We make no health claim either way about mineral content; this answer only records what the product is configured to do.
How much does the Waterdrop G2P600 cost to run over ten years?
About $1,089, taking the $289.00 Amazon price on 2026-09-03 and adding ten years of cartridges at roughly $79.99 a year — $29.99 for the annual WD-G2CF plus $99.99 every two years for the WD-G2P6MRO. Installation adds nothing if you do it yourself, which is how Waterdrop expects it to be done. That figure charges all ten years of filters and does not credit the cartridges included in the box, so it is a slight over-estimate.

Every figure above is taken from the highest-trust source that carries it and re-derived from that source by a separate check. How we verify product data.
What we could not establish, and why
| Field | Why it is blank |
|---|---|
| identity.upc | Two different UPCs are published for this SKU and we could not adjudicate them: Waterdrop's own store record carries barcode 840814199343, while the Amazon listing for ASIN B08746M1NX (sold by Waterdrop Filtration Tech) states UPC 840814171820. Both trace to Waterdrop, so the trust order does not resolve the conflict and we would rather publish no UPC than the wrong one. |
| certified.certIndexKey | No entry for the G2P600 or for Qingdao Ecopure Filter Co. Ltd matching this model exists in our certification index (grep for 'G2P600' across apps/website/data/certifications returned nothing). This is a fact about the coverage of our own corpus and is not evidence about certification; the three dated live directory checks in liveCertChecks are what speak to that. |
| fit.bathroomsServed | Waterdrop publishes a family-size bucket ('4-6', 'Family Size') for the G2P600 but no bathroom count anywhere on the product page, the comparison table or the Amazon listing. A point-of-use RO system feeding one dedicated faucet does not scale by bathroom count in any case, so we did not infer one. |
| fit.roTankCapacity | The G2P600 is tankless: IAPMO R&T classifies it under Product Type 'Plumbed-in to separate tap without reservoir' and Waterdrop markets it as a tankless design, so there is no storage tank to rate. Waterdrop sells an optional pressure tank (PMT) as a separate accessory, which is not part of this system. |
| fit.pressureRange | Waterdrop publishes no feed-water pressure range for the G2P600 on the product page, the G-series comparison table, the two cartridge pages, or its RO installation guide page. The only manual attached to the product listing is titled for a different model (see install.manual), so we had no manufacturer document to take a pressure range from. |
| fit.temperatureRange | Waterdrop publishes no feed-water temperature range in its own materials. The Amazon listing's technical table shows an 'Upper Temperature Rating' of 87 F, but a retailer spec table is the weakest numeric source available and this field feeds a safety-critical operating bound, so we did not adopt it. |
| fit.connectionSize | No inlet or outlet connection size is published on the Waterdrop product page, the comparison table, the cartridge pages or the Amazon technical table. Waterdrop's install video shows the fittings but does not state a size on screen. |
| install.manual | The only document Amazon publishes as the 'User Manual' on the G2P600 listing (m.media-amazon.com/images/I/B1gyJgOlUPL.pdf) has the internal PDF title 'WD-G2-W-User Manual' and its 20 pages never mention G2P600 or 600 GPD, so it is the manual for the 400 GPD G2, a different system with a different membrane cartridge. Waterdrop's own site publishes no G2P600 manual we could find (its sitemap lists manual pages only for the A1). We would rather publish no manual link than one for the wrong model; the separate FAQ document on the same listing is cited throughout group E instead. |
