What reviewers say
Sourced tester consensus for each — the "what people who used it think" layer, not just specs.
IQAir AirVisual Pro
Only one whitelisted outlet, Wirecutter (NYT), hands-on tested this exact model, and it landed in their 'competition' section rather than among the picks. Reviewers praised its easy Wi-Fi setup and clear, practical app, but panned a clunky physical interface and a steep price for a monitor that measures only PM2.5 and CO2 (plus humidity and temperature). No lab numbers were published for this model. (1 sourced review, 1 lab-tested.)
Praised: Easy Wi-Fi setup and connection; Clear, well-laid-out app offering simple, practical air-quality advice.
Flagged: Clunky, frustrating physical interface on the device itself; Too expensive for a monitor measuring only PM2.5 and CO2 (plus humidity and temperature).
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.
