How we gather evidence
We don't just read the marketing copy. Before we score anything, we dig into the data, and this page shows exactly where it comes from.
The short version
We analyze real user reviews from verified purchasers, verify official specifications from manufacturers, check safety databases like CPSC and Prop 65, and validate third-party certifications like NSF and OEKO-TEX. No score gets published until it meets our quality standards.
Where our data comes from
We gather evidence from multiple independent sources, then verify and cross-reference before any score is published. When we can't find solid evidence, we don't guess. We say so.
Real User Reviews
Verified feedback from actual product owners
Official Specifications
Manufacturer data and product documentation
Safety Databases

Our process
Gather
We collect evidence from several independent sources rather than trusting a single input, so one glowing review can never carry a score on its own.
Verify
We cross-reference claims against specs, certifications, and safety records. If something doesn't add up, we dig deeper.
Score
We apply our methodology to calculate scores, with full transparency on the evidence. Every number is traceable.
What we look for
Consistency across sources. If reviews say one thing and the specs say another, that is a red flag. We investigate before scoring.
Verified certifications. "Certified" means nothing without the actual certification. We check for NSF, OEKO-TEX, GREENGUARD, and other third-party standards, not just marketing language.
Safety records. We check CPSC for recalls, Prop 65 for warnings, and manufacturer disclosures for materials like PFAS.
Common questions
Do you test products in a lab?
No. We rely on verified third-party testing and certifications from accredited labs like NSF International and SGS. We don't run our own lab. What we do is confirm that real labs have done the work properly and that the certifications are current.
What if a product has limited reviews?
We say so plainly. When the evidence is thin, we hold back rather than guess, and we are upfront about what we could not confirm.
How often do you update scores?
We re-score a product when meaningful new evidence shows up, such as a recall, a reformulation, or a new round of independent testing. Safety news is what moves a score the fastest.
