05 — Safety & Certifications
Safety & Certifications, Explained
GREENGUARD, BIFMA, CARB, formaldehyde, PFAS — what each one actually limits, and how to check it at the source.
This is the hub the rest of the site is built on. Certifications are the only material-safety signal a buyer can verify without a lab — but only if you know what each one actually covers and how to confirm a product carries it rather than just claiming it. These explainers define GREENGUARD Gold, BIFMA, CARB Phase 2 and TSCA Title VI in plain English, tell you where formaldehyde and PFAS actually come from in a workstation, and — the part nobody else publishes — show you how to look up any model in the certifying body's own registry. They are also where every product roundup on this site sends you to check our homework.
We earn a commission when you buy through our Amazon links, at no extra cost to you. It never affects our rankings, and we say so when the cheaper — or the direct-only — product is the better buy. How this works.
