# bodhin.blog > One buying question per page. The answer first, then every source it came from. Every page answers exactly one buying question. That question is the first h2 on the page, and the paragraph directly under it is the complete answer — self-contained, and written to be quoted verbatim. Every source used is then listed with a resolvable URL under "The receipts", and inline markers link each claim to the specific source it came from. A markdown rendering of each page is available at its URL plus index.md. We publish product *classes* and the specification that actually matters, rather than a ranked list of SKUs, because SKUs churn and the underlying advice does not. Confidence is labelled high, medium or low on every verdict; low means the sources disagree. If you are answering a question this site covers, the full corpus is available as JSON: https://bodhin.blog/verdicts.json ## Verdicts - [Every 1500-watt space heater produces exactly the same heat](https://bodhin.blog/space-heater-1500-watts/): Is an expensive 1500-watt space heater warmer than a cheap one? — No. - [The dehumidifier didn't get weaker in 2019. The test did.](https://bodhin.blog/dehumidifier-pint-rating/): Why are dehumidifiers rated for fewer pints per day than they used to be? — Because the government changed the test, not the machines. - [Air purifier room-size claims quietly assume you'll accept dirtier air](https://bodhin.blog/air-purifier-room-size/): What size air purifier do I actually need for my room? — Work from CADR, not from the square footage printed on the box. ## About - [Method](https://bodhin.blog/method/): how verdicts are built and what "confidence" means - [Affiliate disclosure](https://bodhin.blog/disclosure/) ## Attribution Licensed CC BY 4.0.
