# Editorial Policy & How We Source Data _Last updated: 2026-09-26_ ## What we publish SmartAirGuide publishes buying guides, how-to setup and usage guides, troubleshooting steps and maintenance schedules for home air-quality and comfort appliances. The goal is to help you decide, install, use and maintain an appliance, not simply to list products. ## Where our data comes from - Manufacturer specifications and manuals (capacity, wattage, noise, filter type). - Retailer listings for current model numbers, variants and customer ratings. - Public standards and agencies such as the U.S. EPA, ENERGY STAR, AHRI and the U.S. Department of Energy for how figures are defined and tested. ## Labels you will see We try to make the source of every number obvious: - Manufacturer specification: a figure published by the brand or in the manual. - Retailer rating: a rating and review count shown on a marketplace listing (for example, Amazon), not collected by us. - SmartAirGuide measurement: only used where a page explicitly states we tested the product ourselves. ## What we do not do - We do not present manufacturer or retailer figures as our own test results. - We do not invent ratings or reviews, and we do not apply star ratings we did not collect. - We do not sell rankings or accept payment to place a product higher. - We do not claim in-house lab testing unless a page says so explicitly. ## How products are chosen and how we make money Products are selected to match the criteria explained in each guide. Outbound links to marketplaces may be affiliate links, and we may earn a commission when a visitor buys, at no extra cost to the buyer. Affiliate relationships do not change the criteria we publish; where a page recommends options, it does so after explaining how to choose. ## Corrections and updates Specifications and listings change. If you find an error or an outdated figure, contact support@smartairguide.com and we will review and correct it. Pages carry a Last updated date. ## Frequently asked questions **Q: Do you test the products yourselves?** A: Not currently. Unless a page explicitly says SmartAirGuide measured something, all figures are manufacturer or retailer figures reproduced as listed. **Q: Are your recommendations paid?** A: No. Products are chosen against the criteria in each guide. Some links are affiliate links, but payment does not determine inclusion or ranking. --- Canonical:
