## Independence

    Editorial decisions are made by the editorial team, not by merchants. A
    commercial partner cannot buy a ranking, a score, a "best" label, or a place
    in a roundup. If we cannot recommend a category honestly, we say so.

## Sourcing

    Articles cite manufacturer documentation, public code, government guidance, or
    named owner reports. Statistics without a source are removed. Estimates are
    labelled and their inputs are shown.

## Affiliate links

    Some outbound links are affiliate links. They are marked with
    `rel="sponsored"`, and every article carries a disclosure. The
    commission does not change the price you pay. See the
    [full disclosure](/affiliate-disclosure/).

## Reviews and scores

    Scores are relative to the use case, not absolute. A 7/10 for a two-person
    under-sink RO may be a 4/10 for a household on well water with iron. We
    explain the criteria in the article rather than hiding them in a number.

## Corrections

    We correct factual errors promptly and note the update date. To report an
    error, email [contact@watertreatmentpro.com](mailto:contact@watertreatmentpro.com)
    with the URL and a source.

## AI assistance

    Drafts may be prepared with software assistance, but every published article is
    reviewed against its sources by the editorial team. We do not publish
    unreviewed generated text.

## Review cycle

System and installation guides are rechecked when a manufacturer manual, a certification listing or a plumbing code edition changes. Cost guides are rechecked quarterly. A page that has not been reviewed in twelve months is flagged in the editorial calendar rather than left to drift.
