Methodology
How JFI researches products
JFI Water Filtration prefers manufacturer pages, owner’s manuals, specification sheets, and other identifiable public sources. Product specifications are used only when a source supports them. Unknown fields are omitted rather than guessed. We do not claim hands-on testing, laboratory measurements, or fabricated reviews. We do not invent prices, ratings, review counts, availability, or rankings. Named manufacturer and model identities appear only when documentation supports that identity. We do not scrape Amazon for product copy or images. Generic editorial illustrations may depict rooms, situations, or equipment categories. They are not photographs of a specific commercial model unless an authorized product image is used. If we correct an error, we replace the public version. Prior versions remain in the editorial history. Affiliate relationships, if added later, do not determine factual conclusions. This site also does not: hands-on testing we did not perform; fabricated price or rating tables.
