Why this publication exists
Clear Water Index helps US households choose a home water filter, from a pitcher to tankless reverse osmosis or a whole-house system. The goal is useful clarity: what the offer does, who it may fit, what it costs, where the evidence is strong, and what still needs checking.
How the guides are made
We compare primary merchant information with relevant independent sources, identify important limitations, and build practical tools or frameworks where they make the choice easier. Source dates are shown so readers can judge freshness.
Independence and limitations
We do not invent first-hand experience, expertise, ratings, or guaranteed outcomes. Product capabilities, prices, evidence, and third-party details can change and should be checked against the recorded primary source.
Corrections
A factual correction should include the page address and a reliable source. Material errors are reviewed and updated; significant changes may alter the recommendation.
