Jonathan Amparo

I'm Jonathan Amparo. I'm a software engineer by training and a one-person editorial operation by current occupation. VettedClean is the result of being asked the same question one too many times — "is this cookware actually PFAS-free?" / "does this filter really remove PFAS?" — and discovering that the credible answers are buried in NSF database listings, EPA technical fact sheets, and manufacturer testing pages that are not designed for shoppers.

What I actually do

I read the certifications, the third-party test reports, the regulatory documents, and the published material-property literature. Then I write down the answer in plain language and link to the original source so the reader can verify it. I do not test products. I do not run lab analyses. I do not own, install, or photograph the items I cover. The role here is information aggregation and translation, not product testing — and the editorial methodology page documents that explicitly.

Background

Software engineering background, with a working hobby-grade familiarity with materials chemistry, regulatory frameworks, and the consumer-side literature on environmental toxicology. The expertise I bring to VettedClean is not credentialed laboratory expertise; it is the discipline of reading primary sources carefully, citing them transparently, and refusing to write claims that cannot be sourced.

For health and toxicology questions that go beyond what regulators have defined, I consistently defer to the citation. Tier 1 sources (FDA, EPA, NSF, peer-reviewed research) carry the most weight. Tier 4 sources (manufacturer pages) are useful for documenting what a brand says about its own product but never for certifying a health claim.

Editorial principles I commit to

• Every health or toxicity claim is sourced to a named third party.
• No first-person testing language. No "we use," "we tested," "in our kitchen."
• Affiliate links disclosed above the fold of every article and again in the footer.
• No medical claims. No "clinically proven," "detoxifies," "heals."
• Corrections noted at the bottom of the affected article with date and summary.
