Screening
- Materials disclosed in full — no proprietary 'blend' shortcuts.
- Manufacturing standards and country of origin verifiable.
- No knowingly hazardous ingredients: PFAS, heavy metals, added phthalates, formaldehyde donors, undisclosed fragrance.
- Certifications that actually mean something for the category (NSF for water, GOTS for textiles, MADE SAFE for household).
Evaluation
Every candidate is evaluated against a category-specific rubric — a cast iron pan is not judged by the same criteria as a shower filter. Rubrics cover materials, performance, durability, real-world usability, and honest trade-offs.
Where third-party independent testing exists (for water filters, mattresses, textiles), we weight it heavily. Where it doesn't, we rely on our own long-term household use and cross-check with reviewers we trust.
Trade-offs we always name
No product is perfect. We say what a piece does well, what it doesn't, who it fits, and who it doesn't. If a cheaper alternative would serve most readers better, we say that too.
When we remove a product
A product is removed or downgraded if its formulation changes, a certification lapses, independent testing surfaces a problem, or long-term reader feedback consistently contradicts our recommendation. Changes are logged in our Corrections Policy.
