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).
