Clearly Filtered Review
Clearly Filtered leads the pitcher category on contaminant reduction, with NSF P473 certification for PFAS removal — rare in the pitcher market.
Clearly Filtered: The Only Pitcher Brand That Takes PFAS Seriously
Clearly Filtered occupies a unique position in the water filter market: they are the only pitcher manufacturer that has pursued and obtained NSF/ANSI P473 certification for PFAS removal — the only standard that legally validates PFAS reduction claims. While Brita, PUR, and ZeroWater dominate market share, Clearly Filtered dominates the certification table for the contaminant that most concerns health-conscious buyers in 2025.
That focus on certification isn't just marketing positioning — it reflects a genuine product philosophy. Clearly Filtered tests against 365+ contaminants across their product line, publishes third-party test data, and maintains certifications across NSF 42, 53, 401, and P473. No other pitcher manufacturer comes close to that coverage.
Clearly Filtered Brand Score: 9.2/10
NSF 42, 53, P473, 401 — the most comprehensive certification suite in the pitcher category

$90 pitcher + $25/100-gal filters — premium price, premium performance
100-gallon pitcher filter life is average — shorter than some for its price

Primarily sold direct and on Amazon — not in major grocery/pharmacy chains
