How WaterVerdicts researches, verifies, updates, and monetizes water-treatment content.
Our editorial standard is simple: claims should be traceable.
We prioritize primary technical documentation, certification databases, public water-quality sources, and current manufacturer specifications. We distinguish a complete-system certification from a component certification and avoid extending a claim from one model to another without evidence.
We do not claim hands-on testing unless testing actually occurred and the method is described. We do not invent authors, ratings, laboratory results, prices, or certification status.
Water-treatment recommendations can depend on local water chemistry. Where appropriate, we tell readers to use a current municipal report or laboratory test rather than assume regional averages apply to a specific home.
Affiliate relationships can influence which merchants are available through outbound links, but they do not determine the framework used to compare products.
