Where the two actually differ on the specs we track (4 of 7). Matching specs are omitted.
Sourced tester consensus for each — the "what people who used it think" layer, not just specs.
Two whitelisted testers (TechHive, Reviewed/USA Today) rate the Airthings View Plus the best overall home air-quality monitor for its seven sensors, radon detection, easy setup and app, and smart-home integration. Both flag its high price (~$300–$330) and the lack of an included AC power adapter; TechHive additionally dings the missing carbon-monoxide sensor and up-to-a-month sensor calibration. Neither published benchmarked accuracy numbers, so real-world sensor precision is untested in these sources. (2 sourced reviews, 1 lab-tested.)
Praised: Seven built-in sensors with comprehensive coverage including radon; Easy setup and an easy-to-navigate companion app; Smart-home integration (Alexa/Google) plus hub functionality.
Flagged: Expensive (~$300+), among the priciest options; No AC power adapter included in the box; No carbon monoxide sensor.
