How these numbers are calculated

The sample consists of the product listings on the Air Purifiers spec sheet: 13 listing identifiers drawn from 17 comparison pages. Identical ASINs are grouped; different ASINs are not merged by name. This can include several variants of one model. These descriptive figures cannot estimate market prevalence or what buyers prefer.

A spec is reported only when at least four listings list it and at least 70% of those values parse as one number in one unit. Mixed units are converted (grams to ounces, weeks to days). Values quoted as a range are left out rather than guessed. Yes/no features use explicitly parseable responses. Other feature summaries use specified text patterns in the reported descriptions; these are not independently verified product capabilities.

Documented revisions replace older inputs for the same listing. Conflicting descriptions and unavailable values are excluded from calculations, rather than counted as zero or a missing feature. Many remaining source claims still need review. Spot an error? Email hello@speckatlas.com with the model and the source.
