What reviewers say
Sourced tester consensus for each — the "what people who used it think" layer, not just specs.
Airthings View Plus
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.
Aranet4 Home
Only one whitelisted tester covers the Aranet4: NYT Wirecutter, which reports hands-on use over years and praises its accuracy and reliability, but flags that it only tracks CO2. In its October 2025 update Wirecutter places the Aranet4 in the 'competition' section rather than as a pick, favoring the multi-pollutant AirGradient One (which uses the same NDIR CO2 sensor plus more). No lab-measured Aranet4 figures were published; the surviving quotes come from Wirecutter's competition write-up. (1 sourced review.)
Praised: Accurate, reliable CO2 readings confirmed over years of hands-on use.
Flagged: Measures only CO2, unlike multi-pollutant rivals.
