Clearly Filtered is the pitcher you buy when you want under-sink-grade contaminant scope without an under-sink install. The brand puts more contaminants on its published data sheet than any other pitcher in this category — lead, PFAS, fluoride, chromium-6, arsenic, microplastics, pharmaceutical residues — and points to a single IAPMO-tested document as the receipt. The price is roughly three times a Brita Elite. The question is whether the cert paper trail and the broader contaminant coverage justify the premium.
The honest verdict up front: Clearly Filtered earns its premium for households whose contaminant priority list extends past PFAS and lead — fluoride, chromium-6, or pharmaceutical residues all live on the data sheet, and most pitchers do not target them. It is the wrong pitcher for buyers whose only concern is PFOA/PFOS (Brita Elite has direct NSF/ANSI P473 for a third the price), for households that want the broadest possible no-plumbing scope (AquaTru countertop reverse osmosis is the right tool there), and for the budget-pitcher buyer who just wants chlorine-taste improvement on the cheap. If you are not sure which pitcher matches your specific priority, our best pitcher filter by priority guide matches you to a single row based on whether lead, PFAS, fluoride, or cost is your primary concern.
What Clearly Filtered actually is
The unit is an 80oz lower reservoir with a 64oz upper reservoir, sized for the typical 2-to-3-person household. The pitcher is built in the USA from medical-grade Tritan — BPS/BPA-free, phthalate-free, and free of estrogen and androgen activity per the brand's published material claims. The filter cartridge is a multi-stage carbon-block system that the brand describes as a "three-stage" assembly: granular and block activated carbon at the inlet for chlorine and large organics, a custom blend of secondary media in the middle for PFAS, lead, fluoride, and dissolved metals, and a polishing stage at the outlet. Cartridge life is rated at 100 gallons, which translates to roughly four months for a household of two-to-three.
That is a longer cartridge life than ZeroWater (15-25 gallons in typical municipal water) and a shorter cycle than Brita Elite (~120 gallons). The trade-off in both directions: Clearly Filtered's cartridge does more chemistry per pass, so it saturates faster than a less-aggressive cartridge would, but it lasts long enough to keep the per-gallon math reasonable.
The certification situation
This is where editorial nuance matters. Clearly Filtered's pitcher performance data page states the unit is "independently tested to comply with" NSF/ANSI standards 42, 53, 401, and P473. Testing was performed by QFT — a lab now operating as IAPMO New Jersey, a division of IAPMO, an ANSI-accredited ISO 17025 certified laboratory. Each of the four standards covers a specific category of claim:
- NSF/ANSI 42 — aesthetic effects (chlorine taste and odor, particulates)
- NSF/ANSI 53 — health effects (lead, VOCs, cysts, chromium, growing list of PFAS reduction claims)
- NSF/ANSI 401 — emerging contaminants (pharmaceutical residues, herbicides, pesticides)
- NSF/ANSI P473 — PFOA and PFOS reduction protocol
Four standards on one data sheet is unusual in the pitcher category. Most pitcher brands hit one or two and leave it there.
Here is the editorial caveat worth noting. Clearly Filtered does not appear in the NSF International certified-products database directly. A search of the NSF lead-reduction certified products listings under NSF/ANSI 53 does not return the brand. That is because IAPMO R&T testing is a different certification body — it tests against the same NSF/ANSI protocols using the same ISO 17025 methodology, but the resulting listing is in IAPMO's database, not NSF's. AquaTru's countertop uses the same IAPMO route, and that distinction is covered elsewhere on this site.
The phrase "tested to comply with" is also editorially distinct from "certified by." Both are real third-party data points, but a buyer who specifically wants the NSF mark on the box should know that Clearly Filtered will not show up in the NSF database. If that paper-trail granularity matters to you, Brita Elite is directly NSF/ANSI P473 certified for PFOA and PFOS — the cleanest "find it on the NSF site" pitcher option in the category.
A peer-reviewed Water Research evaluation found that NSF/ANSI 53 certified filters using activated carbon and ion-exchange media reduce lead effectively across a range of source-water chemistries when properly maintained. Clearly Filtered's chemistry sits in that academically validated category — the IAPMO-against-NSF-protocols testing is meaningful evidence even without the direct NSF listing.
What it actually removes
Clearly Filtered's published data sheet is unusually specific for a pitcher, naming reduction percentages by contaminant. The headline numbers from the IAPMO-performed testing:
- Lead — 99.34% reduction
- PFOA — greater than 99.00% reduction
- PFOS — greater than 99.50% reduction
- Fluoride — greater than 99.54% reduction
- Chromium-6 (hexavalent) — 99.68% reduction
- Arsenic — 98.00% reduction
- Microplastics — greater than 99.99% reduction
- Ibuprofen (representative pharmaceutical) — greater than 99.98% reduction
Fluoride is the standout. Most pitchers do not meaningfully reduce fluoride — activated carbon alone does not target it, and the contaminant typically requires reverse osmosis or specialized alumina/bone-char media. Clearly Filtered's claimed >99% fluoride reduction is rare in the pitcher category and is one of the load-bearing reasons buyers pay the premium. The independent Water Filter Guru lab evaluation confirmed 100% fluoride reduction in their testing, which is the kind of independent corroboration that strengthens the brand's claims.
For households motivated by the federal PFAS rule — the EPA finalized MCLs of 4 parts per trillion for PFOA and PFOS in April 2024, with utility compliance by 2029 — Clearly Filtered's PFAS coverage hits well below that threshold based on the published testing.
The honest caveat the independent reviewer raised: not every claim survived real-world testing. Water Filter Guru's lab work matched or exceeded the brand's claims for fluoride, uranium, and trihalomethanes, but found meaningful shortfalls on sulfate (3% versus claimed 99.88%), nitrate (11% versus claimed >99.96%), and several minor metals like strontium and molybdenum. Those are not the headline contaminants most buyers care about, but the gap between brand claims and real-world results on the long-tail contaminants is worth knowing. The lead, PFAS, fluoride, and chromium-6 numbers — the ones that drive the purchase decision — held up.
Compared to Brita Elite
Brita Elite (Longlast+) holds direct NSF/ANSI P473 certification for PFOA and PFOS reduction and direct NSF/ANSI 53 certification for lead. That is the cleanest paper trail in the entire pitcher category — searchable on the NSF website, verifiable in seconds. Brita Elite is also roughly $35 versus Clearly Filtered's $90, with a 120-gallon cartridge that is among the lowest per-gallon costs in the pitcher segment.
What Brita Elite does not do is touch fluoride, chromium-6, arsenic, or pharmaceutical residues. The cert is narrow and the contaminant scope matches. If your municipal supply has unremarkable fluoride and your priority list is "lead and PFAS, that is it," Brita Elite is the structurally-cheaper-and-equally-rigorous pick. If your priority list runs longer, Clearly Filtered's broader IAPMO-tested scope earns the premium.
Compared to Epic Pure
Epic Pure is the closest direct competitor — same premium-pitcher segment, same multi-stage carbon-block architecture, same IAPMO-tested-against-NSF-P473 framing for PFAS, similar contaminant scope on the published data sheet. Unit price is around $70 versus Clearly Filtered's $90; cartridge life is similar at ~150 gallons. Epic Pure publishes its own test results page with comparable rigor.
The differentiation between these two is honestly thin on chemistry. Clearly Filtered has a slightly larger reservoir (80oz lower vs Epic's 64oz lower), uses Tritan rather than standard BPA-free plastic, and publishes a longer named-contaminant list with reduction percentages. Epic Pure is cheaper. Neither is structurally wrong; we lean Clearly Filtered for the editorial story (medical-grade Tritan, broader published data sheet), Epic Pure for the budget-conscious shopper who wants the same chemistry at a lower price.
Compared to AquaTru countertop reverse osmosis
AquaTru solves a different problem at a different price point. AquaTru is the no-plumbing reverse-osmosis countertop unit at $449 — broader contaminant scope (84-contaminant IAPMO-tested list versus Clearly Filtered's published pitcher data sheet), no install, but with a counter footprint, an audible pump cycle, and water sent to drain. The trade-off is form factor and cost.
For a household that wants a single filtered-water solution and has the counter space and budget for it, AquaTru wins on contaminant breadth. For a household that wants the broadest practical pitcher chemistry without giving up counter space, Clearly Filtered is the move. These are not direct competitors so much as different segments — pitcher buyers and countertop-RO buyers usually self-select before they reach the comparison.
Pros
Broadest published contaminant scope in the pitcher category. Lead, PFAS, fluoride, chromium-6, arsenic, microplastics, and pharmaceutical residues all on a single IAPMO-tested data sheet. Most pitchers cover one or two of those categories.
Fluoride reduction at greater than 99%. Rare in the pitcher segment. Activated carbon alone does not target fluoride; Clearly Filtered's media blend does. Independent lab work has corroborated the headline fluoride number.
IAPMO testing against four NSF/ANSI standards. 42 (aesthetic), 53 (health effects), 401 (emerging contaminants), and P473 (PFAS protocol). Same testing body that AquaTru uses. ISO 17025 accredited, ANSI accredited certification body. Real third-party data, even if the listing does not appear in the NSF database directly.
Built in the USA from medical-grade Tritan. Domestic manufacturing and the Tritan housing are unusual in the pitcher category; most competitors use generic BPA-free polypropylene. The structural premium is meaningful for buyers who care about material sourcing.
Reasonable cartridge life for the chemistry. 100 gallons per cartridge, roughly four months for a 2-3 person household. Faster saturation than a basic carbon block but sustainably longer than ZeroWater.
Cons
No direct NSF database listing. The brand will not appear if you search nsf.org for "Clearly Filtered." The IAPMO listings live in a different database. This is editorially fine — same protocols, same accreditation — but if you specifically want to verify the cert on the NSF site, you will not find it. Brita Elite aligns with that use case given its direct NSF listing.
Pricier upfront than commodity pitchers. $90 versus Brita Elite's $35 is a meaningful gap. The premium is justified when there is broader contaminant scope to target. For chlorine-taste-only households, it is overkill.
Slow fill rate. ~2.27 gallons per hour per independent testing — slower than Brita Elite's ~2.92 GPH. The chemistry trade-off is real: longer dwell time means better reduction percentages, but the pitcher does not pour fast. Refill, walk away, come back.
Heavy when full. 80oz of water plus the upper reservoir adds weight that shorter members of the household may notice. Not unique to Clearly Filtered, but worth flagging at this size class.
Independent testing flagged some long-tail gaps. Water Filter Guru's lab evaluation showed sulfate, nitrate, and several minor metals underperforming the brand's claims. The headline contaminants — lead, PFAS, fluoride, chromium-6 — held up. Buyers whose priority is sulfate or nitrate reduction should know the gap exists.
Locked into Clearly Filtered replacements. Like most premium pitcher brands, the cartridge geometry is proprietary. Generic pitcher cartridges do not fit. Supply disruption with the brand has no commodity fallback.
Cost of ownership
Five-year math depends on cartridge cycle and household consumption. At the $90 unit price plus roughly three cartridge replacements per year at $55 each, the per-gallon cost lands meaningfully above Brita Elite (the cheapest pitcher per gallon by a wide margin) and meaningfully below AquaTru's countertop RO. In the same neighborhood as Hydroviv under-sink and Aquasana AQ-5300 on a five-year basis, but with the no-plumbing convenience that those under-sink units do not offer.

Who Clearly Filtered is right for
Renters who cannot install under the sink. Buyers with fluoride, chromium-6, arsenic, or pharmaceutical residues high on their contaminant priority list — the IAPMO-tested data sheet is the broadest in the pitcher category for those targets. Households that want the editorial story of medical-grade Tritan, USA-built, and four NSF/ANSI standards on one document. Buyers who care about contaminant scope more than they care about finding the certification mark in the NSF database directly.
Who Clearly Filtered is not right for
Buyers whose only concern is PFOA/PFOS reduction — Brita Elite holds direct NSF/ANSI P473 for a third the price. Households with unremarkable municipal water whose only complaint is chlorine taste — a $40 commodity pitcher does that well enough. Buyers who want the broadest possible no-plumbing contaminant scope — AquaTru countertop RO is the right tool there, with a counter footprint and a $449 unit cost. Buyers who specifically need to verify the cert on the NSF database directly — the IAPMO listing is real but lives in a different database.
Verdict
Clearly Filtered earns the editorial recommendation for the pitcher buyer whose contaminant priority list runs broader than just PFAS and lead. The IAPMO-tested data sheet covers more named contaminants than any other pitcher in this category, the fluoride reduction at greater than 99% is rare in the segment, the medical-grade Tritan housing and USA manufacturing are real differentiators, and the four-standards testing is functionally equivalent to NSF certification for the standards covered. The database distinction (IAPMO listings are not searchable on the NSF site) is noted here because some buyers care about which certification body's mark is on the box.
If your only concern is PFOA/PFOS, get Brita Elite — same chemistry validation against the protocol that matters, a third the price. If you want broader-than-pitcher contaminant scope and have the counter space, get AquaTru. If your contaminant list runs long and you want pitcher form factor, Clearly Filtered is the premium-tier pitcher that earns its premium.
