The pitcher to pick when fluoride is your target. It lab-tests to near-total reduction of fluoride, lead, PFAS, and arsenic while keeping beneficial minerals, which is a wider list than any other pitcher we cover. You pay for it with a slow pour, a premium price, and health claims that are independently lab-tested rather than NSF-53 certified.

The widest-removal pitcher, with one honest asterisk
Most filter pitchers pick a lane: cheap and carbon-only like Brita, or aggressive on total dissolved solids like ZeroWater. The Clearly Filtered Clean Water Pitcher goes after the longest contaminant list in the category. Its Affinity filtration media is built to reduce more than 365 contaminants, and the reductions that matter most are strong: in the company’s third-party lab testing the filter cut lead by 99.3%, fluoride by more than 99%, PFOA and PFOS by more than 99%, arsenic by 98%, and trihalomethanes by more than 99%. Fluoride and arsenic in particular are contaminants almost no gravity pitcher touches, and unlike reverse osmosis or ZeroWater’s ion-exchange resin, it leaves beneficial calcium and magnesium in the water, so it does not taste flat.
The asterisk is certification, and we want to be plain about it. The pitcher is NSF certified to NSF/ANSI Standard 42 (chlorine taste and odor) and Standard 372 (lead-free materials), but it is not NSF certified for Standard 53, the health-effects standard that covers its lead, fluoride, PFAS, and arsenic claims. Those reductions are verified by an independent ISO 17025 laboratory (IAPMO New Jersey, formerly QFT) testing to NSF/ANSI 53 protocols. That is real, credible, third-party data, and better than the marketing-only claims many pitchers rest on. It is just not the same as full system certification, and on a health topic that distinction is worth knowing before you buy. Add a genuinely slow pour and the highest running cost of any pitcher we cover other than ZeroWater, and you have a superb filter that earns its 4.1 rather than sweeping the category.
Best for: households on fluoridated or contaminant-heavy tap water who specifically want fluoride, PFAS, or arsenic reduced from a no-install pitcher, value natural mineral taste over near-zero TDS, and will accept a slow fill and premium filter cost.
How it scored, category by category
Each category is weighted into the overall score. Contaminant reduction carries the most weight, and it is where the Clearly Filtered pitcher leads the field. Slow flow and a high price are what hold the total to 4.1.
What it removes
The figures below are the reduction percentages Clearly Filtered publishes from its third-party lab testing. We separate what is NSF certified from what is independently lab-tested to NSF methods, because the two are not the same thing and the difference matters on a health purchase.
| Contaminant | Reduction | Verification |
|---|---|---|
| Chlorine (taste & odor) | >99% | NSF 42 certified |
| Lead | 99.3% | Lab-tested, NSF 53 method |
| Fluoride | >99% | Lab-tested, NSF 53 method |
| PFAS (PFOA / PFOS) | >99% | Lab-tested, NSF 53 method |
| Arsenic | 98% | Lab-tested, NSF 53 method |
| Trihalomethanes (TTHMs) | >99% | Lab-tested, NSF 53 method |
| Lead-free materials | Yes | NSF 372 certified |
The pitcher carries NSF/ANSI 42 and 372 system certification. Its lead, fluoride, PFAS, arsenic, and THM reductions are verified by an independent ISO 17025 lab (IAPMO New Jersey, formerly QFT) to NSF/ANSI 53 test protocols, but the pitcher is not NSF 53 certified as a system. We credit the lab-tested figures toward the score while flagging the certification gap. Unlike reverse osmosis or ion-exchange pitchers, it retains beneficial minerals, so the water does not taste flat. See our fluoride guide and PFAS guide for what these contaminants are and how filters are tested.
Pros and cons
What we liked
- The widest reduction list of any pitcher, including fluoride and arsenic
- Strong third-party lab numbers on lead, PFAS, and THMs
- Keeps beneficial minerals, so the water tastes natural, not flat
- Long 100-gallon filter life and sturdy medical-grade Tritan build
Worth considering
- Slow pour; independent testing clocked ~2.27 GPH, over 20 minutes for a full pitcher
- Priciest pitcher here, both the unit and the replacement filters
- Health claims are lab-tested to NSF 53 methods, not NSF 53 certified
- No filter-life indicator, and a fiddly spout flap when pouring
What actual owners report
Our score reflects tested performance. Owner sentiment, summarized from verified buyer and independent long-term reviews, is largely positive and splits along a familiar line for thorough filters.
Owners are impressed by how much the filter removes and by the clean, still-mineral taste, and many buy it specifically to get fluoride out. The recurring frustrations are how slowly it filters and how much the replacement filters cost.
Owners consistently praise
- Clean taste that still feels like water, not flat like RO
- Confidence in the broad removal, fluoride and PFAS especially
- Solid, well-made pitcher that feels worth the price
Common complaints
- Slow filtering; you wait noticeably for a full pitcher
- Replacement filters are expensive over a year
- Spout flap and lack of a filter-change indicator annoy some

The details
Common questions
Does the Clearly Filtered pitcher remove fluoride?
Yes, and that is its signature feature. Very few gravity pitchers reduce fluoride at all, and in Clearly Filtered’s third-party lab testing the filter reduced fluoride by more than 99%. That result is independently lab-tested to NSF/ANSI 53 methods rather than NSF 53 certified, but it is credible third-party data. For what fluoride is and the state of the research, see our fluoride guide.
Is Clearly Filtered actually NSF certified?
Partly, and it is worth being precise. The pitcher is NSF certified to NSF/ANSI Standard 42 (chlorine taste and odor) and Standard 372 (lead-free materials). Its headline health claims, lead, fluoride, PFAS, and arsenic, are not NSF 53 certified; they are verified by an independent ISO 17025 laboratory testing to NSF/ANSI 53 protocols. That is stronger than manufacturer-only claims but short of full system certification. If you want core claims that are NSF 53 certified, the ZeroWater pitcher is the certified alternative.
Why is it so slow to filter?
The dense Affinity media that captures so many contaminants is also what slows the pour. Independent testing measured about 2.27 gallons per hour, roughly 13 minutes to filter a half-gallon reservoir, so a full pitcher takes over 20 minutes. Rinsing a new filter before first use and keeping the upper reservoir topped up helps, but a slow flow is inherent to how thoroughly it filters. If speed matters more than breadth, a standard carbon pitcher like Brita Elite is faster.
Clearly Filtered or ZeroWater?
They are the two most thorough pitchers we cover, aimed at different priorities. Clearly Filtered removes a wider list, adds fluoride and arsenic, and keeps beneficial minerals so the water tastes natural. ZeroWater drives total dissolved solids close to zero, has NSF 53 certified core claims and an included TDS meter, and costs less upfront, but the water tastes flat and its filters run out faster. See how the pitchers compare in our best water filter pitchers guide.
Should you buy it?
Buy the Clearly Filtered pitcher if you want the broadest contaminant removal a no-install pitcher can deliver, especially fluoride, PFAS, or arsenic, and you would rather keep natural mineral taste than chase a near-zero TDS reading. Go in knowing you are paying a premium and accepting a slow pour, and that the health claims are independently lab-tested to NSF 53 methods rather than NSF 53 certified. If you want NSF 53 certified core claims and lower cost, the ZeroWater pitcher is the certified pick, and if you are ready to step up to reverse osmosis without plumbing, the countertop AquaTru Carafe filters even more, for a higher upfront price but a lower cost per gallon.
