Waterdrop Water Filter Review — Which Models Actually Remove PFAS?
Waterdrop makes 11 different water filters. Some remove PFAS. Some do not. The difference comes down to one thing: whether the system uses reverse osmosis. Here is the full breakdown.

The Short Answer
- Removes PFAS: G3P800, G2P600, X12, D6, D4 — all RO systems. Certified NSF 58.
- Does NOT remove PFAS: N1 pitcher, WD-10UB under-sink, and all non-RO countertop models. NSF 42/53 only.
- Best Waterdrop for PFAS: G3P800 — 800 GPD, tankless, includes remineralization.
About Waterdrop
Waterdrop is a Chinese water filter brand founded in 2015 as part of Shenzhen Angel Drinking Water Industrial Group. They sell primarily through Amazon and their own website, with US warehouses in Texas and California for fast domestic shipping.
Their RO system line — especially the G3P800 — has become one of the most reviewed under-sink RO systems on Amazon. Their non-RO products (pitchers, basic under-sink carbon filters) target budget buyers who want general water improvement.
The brand's credibility problem is that buyers searching for “Waterdrop PFAS filter” may find the pitcher or non-RO carbon models. Those products are real — but they are not PFAS filters. Only the RO systems remove PFAS, and only via the RO membrane.
Every Waterdrop Model — PFAS Removal Status
| Model | Type | Removes PFAS? | Certification | Price |
|---|---|---|---|---|
| G3P800 (RO) | Under-sink RO | Yes (via RO) | NSF 58 | $279–$349 |
| G2P600 (RO) | Under-sink RO | Yes (via RO) | NSF 58 | $229–$279 |
| X12 (RO) | Under-sink RO | Yes (via RO) | NSF 58 | $249 |
| D6 (RO) | Under-sink RO | Yes (via RO) | NSF 58 | $299 |
| N1 Pitcher | Pitcher | No | NSF 42, 53 | $28–$35 |
| WD-10UB Under-Sink | Under-sink carbon | No | NSF 42, 53 | $89–$129 |
| Countertop (non-RO) | Countertop carbon | No | NSF 42, 53 | $99–$149 |
Only RO systems have been independently certified for the type of filtration that removes PFAS. Non-RO Waterdrop products use carbon block or granular carbon — the same technology as Brita and PUR.
Waterdrop G3P800 — Deep Review
The G3P800 is Waterdrop's flagship RO system. Here is everything worth knowing.
Best for PFAS Removal
Waterdrop G3P800 Tankless RO System
$279–$349
What We Like
- 800 GPD output — fills a glass in about 8 seconds at the faucet
- Tankless design — no large storage tank under the sink
- 7-stage filtration including PP sediment, three carbon stages, RO membrane, and remineralization
- NSF 58 certified — independently verified RO performance
- Remineralization filter adds calcium and magnesium back after RO stripping
- Smart LED panel shows filter life and real-time TDS reading
- 3:1 pure-to-waste ratio — better than many older RO systems
What Could Be Better
- Wastes about 3 gallons of water per gallon filtered (standard RO trade-off)
- Requires a power outlet under the sink for the pump
- Installation requires connecting to the cold water supply and the sink drain
- Removes all minerals including beneficial calcium and magnesium (remineralizer stage helps)
- NSF 58 covers RO performance — does not specifically list PFAS compound removal rates
- Annual filter replacement cost of $79–$120 is real
Our Verdict
The Waterdrop G3P800 is the best under-$350 tankless RO system we have tested. Reverse osmosis removes PFAS at 99%+ — not just PFOA and PFOS, but the full range of compounds including short-chain replacements. The remineralization stage is a genuine plus, not just marketing. If you want thorough, ongoing PFAS removal without a tank taking up half your cabinet, this is the right system.
Flow speed in real life
800 GPD sounds like a lot — and it is. That works out to about 33 gallons per hour, or roughly half a gallon per minute at the faucet. Most users report filling a 16 oz glass in 8–10 seconds. Compare that to older 50 GPD RO systems that took 30+ seconds per glass. The G3P800 is noticeably faster than budget RO systems.
Annual filter cost breakdown
The G3P800 uses three filter types: CF (pre-filter carbon, $19–$25), RO membrane ($45–$60), and MRO (post-carbon + remineralizer, $29–$35). Replacing all three every 12 months costs roughly $93–$120. The RO membrane can go 24 months in most homes, which lowers annual costs to $60–$80 in years 2 and 4.
Installation complexity
The G3P800 is marketed as DIY-friendly, and for most people that is accurate. You need to: (1) connect to the cold water supply line, (2) run the drain line to the P-trap, (3) mount the system in the cabinet, and (4) install the dedicated faucet. Most installs take 45–90 minutes. The included quick-connect fittings are straightforward. The only tricky part is the drain connection — some P-traps require a drill.
The Waterdrop Pitcher — Important Correction
The Waterdrop pitcher does not remove PFAS
Many buyers searching for Waterdrop PFAS products find the N1 pitcher and assume all Waterdrop products share the same filtration. They do not. The pitcher uses activated carbon — NSF 42 and 53 certified — which removes chlorine, taste, and some metals. It is not NSF P473 certified and makes no PFAS removal claims.
| Product | What It Removes | PFAS? | Certification |
|---|---|---|---|
| Waterdrop N1 Pitcher | Chlorine, taste, some heavy metals | No | NSF 42, 53 |
| Clearly Filtered Pitcher | PFAS, chlorine, lead, 365+ contaminants | Yes (99.9%) | NSF P473, 42, 53, 401 |
If you want a PFAS-certified pitcher, the Clearly Filtered is the only widely available option that holds NSF P473 certification.
Waterdrop RO vs Clearly Filtered Under-Sink
Both are legitimate PFAS under-sink filters. The choice comes down to technology preferences:
Who Should Buy Waterdrop
Buy Waterdrop RO if you...
- Own your home and can do an under-sink install
- Want RO-level PFAS removal across all compound types
- Prefer a lower upfront price than Clearly Filtered
- Want fast water flow at the faucet (800 GPD)
Skip Waterdrop if you...
- Want a pitcher — the N1 pitcher does not remove PFAS
- Rent — under-sink installation may not be allowed
- Have a water-scarce home — RO waste water adds up
- Want NSF P473 certification specifically called out
Common Questions
Does the Waterdrop pitcher remove PFAS?+
No. The Waterdrop N1 pitcher uses activated carbon to reduce chlorine, some heavy metals, and organic compounds. It is NSF 42 and 53 certified — but not NSF P473. Without P473 certification, Waterdrop makes no verified PFAS removal claims for its pitcher. If you want a certified PFAS-removing pitcher, look at the Clearly Filtered Water Pitcher instead.
How often should I replace Waterdrop filters?+
For the G3P800 RO system: the PP sediment and carbon pre-filters need replacement every 6 months, the RO membrane every 24 months, and the post-carbon and remineralization filters every 12 months. The smart panel on the G3P800 tracks each filter independently and shows when a replacement is due. Skipping filter changes on any RO system is a real problem — a spent RO membrane can allow contaminants through.
Where are Waterdrop filters made?+
Waterdrop is a Chinese brand founded in 2015 under Shenzhen Angel Drinking Water Industrial Group. Their filters are manufactured in China and shipped via US warehouses (primarily Texas and California). Quality control is generally consistent, and their Amazon ratings across RO models are strong (4.4–4.6 stars with thousands of reviews). The NSF 58 certifications on their RO systems are issued by accredited US testing labs.
Waterdrop G3P800 vs Clearly Filtered — which is better?+
Different tools for different needs. The Waterdrop G3P800 uses RO technology — 99%+ PFAS removal across all compounds, including short-chain PFAS that carbon filters sometimes miss. It produces waste water. The Clearly Filtered under-sink uses specialized carbon block — 99.9%+ PFOA/PFOS removal, NSF P473 certified, no waste water, and keeps beneficial minerals. Both are legitimate PFAS filters. Choose RO if you want the broadest coverage. Choose Clearly Filtered if you prefer no waste water and certified carbon filtration.
Is Waterdrop a reliable brand?+
For their RO systems, yes. The G3P800 and similar RO models have NSF 58 certifications, strong user reviews, and a US customer service operation. Their non-RO models (pitchers, carbon under-sink units) are fine for general water improvement but should not be marketed — or purchased — for PFAS removal. The key is knowing which product category you are looking at.
Bottom Line
Waterdrop's RO systems are legitimate PFAS filters. Their pitchers and non-RO under-sink models are not. If you are specifically buying Waterdrop for PFAS removal, you want the G3P800, G2P600, X12, or D-series RO systems — not the pitcher or carbon countertop units. Check the model before you buy.
