How much can I save?

$257 −70%

Clearly Filtered pitcher $110 vs. Big Berkey (2.25 gal, 2 Black Berkey elements) $367

Different type of product It doesn't do everything the premium pick does (see trade-offs), so it isn't used for "save up to".

Premium: Price at BigBerkeyWaterFilters.com, an authorized retailer (17 Oct 2026). Price details

What do I give up?

A 10-cup pitcher, not a 2.25-gallon countertop tank: you refill it far more often. Lead/PFAS results are lab tests, not an NSF/ANSI 53 certification (in progress per the brand).

Important differences and trade-offs

A 10-cup pitcher, not a 2.25-gallon countertop tank: you refill it far more often. Lead/PFAS results are lab tests, not an NSF/ANSI 53 certification (in progress per the brand).
Manufacturer claim Not certified to NSF/ANSI 53 or 401 yet (the brand says certification is in progress)
Not yet verified Non-electric: the electrical safety check doesn't apply

How we scored the Clearly Filtered pitcher

NSF-certified to NSF/ANSI 42 (chlorine, taste, odour), current listing; lead, fluoride, PFAS and other reductions come from independent ISO/IEC 17025 lab testing (QFT, now IAPMO New Jersey, Nov 2025) published as a brand-compiled performance data sheet, not a certification → 18/25
Full spec and per-contaminant results published; it's a 10-cup pitcher, not reverse osmosis or a big countertop unit, so it only partly matches the premium pick → 15/20
Material safety: NSF-certified to NSF/ANSI 372 (lead-free materials) → 15/15
Separates what is certified (42, 372) from what is only lab-tested, and says 53/401 certification is still in progress → 15/15
Limited lifetime (base 8) +2 for a 30-day full refund → 10/10
Value: 13/15 (computed from price)

Ranking: Renvo Score first, then price. Products without enough evidence for a score are listed after scored ones, by price. We recommend products scoring 60 or more (80+ "Great swap", 60–79 "Good swap"). Scores of 45–59 ("Mixed evidence") and 30–44 ("Weak") passed our safety and company checks but rest mostly on the brand's word. "Not scored" means a safety record or company address couldn't be verified. Scale revised 18 Oct 2026 (changelog). Commission never affects order, and sponsorships cannot buy higher rankings (§ 5b UWG, ranking factors).

What the claims are worth

Brand statements (e.g. "low EMF", irradiance figures) are marketing claims unless an independent measurement is linked. We make no health claims and don't test products hands-on. See how we grade evidence.
