How these numbers are calculated

The sample is every air purifier on the Air Purifiers spec sheet: 13 models drawn from 17 comparison pages, matched by ASIN and model name so no model is counted twice. It is the set of products we chose to compare, not a random sample of the market, and it leans towards models people actually shop for.

A spec is reported only when at least four models 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. Feature shares count a model only when its page gives a clear yes or no.

Values are as published by the manufacturer unless a comparison page says otherwise. Spot an error? Email hello@speckatlas.com with the model and the source.
