Brita vs Clearly Filtered: which is actually certified — and what does a certified gallon cost?
Last reviewed July 2026.
Same job, same shelf — but the certifications underneath are not the same. Here is Brita against Clearly Filtered on the only two axes we score: what the certification actually covers, and what a certified gallon costs.
- Brita: cheapest certified-for-lead filter is the OB06 at $0.167/certified gallon (WQA, NSF/ANSI 42, 53, 401).
- Clearly Filtered: no accredited certification at all — independent lab tests only, with no public listing behind them.
