I don't know about the awair specifically, but it's worth being cautious about cheap air quality monitors. There seems to be little good standardized testing of them, and sometimes even major brands can have abysmal accuracy. See for example the EPA study "Evaluation of Emerging Air Sensor Performance" [1], some of them have very low or even zero correlation with reference monitors. It'd be nice to see some more uniform independent lab testing and marking standards there, or maybe there already are? I've rarely been able to find comprehensive evaluations however. At least it does look like the EPA is looking at them more, last year there was a very interesting webinar overview [2] of research being done on them. There are plenty of fully dumb plain monitors too, but since you picked a smart IOT one I'd personally really want to make sure it'd work LAN-only and supported a wide array of integrations. From a quick glance it's not clear the Awair does that, and it does not have HomeKit support for example. ---- 1: https://www.epa.gov/air-sensor-toolbox/evaluation-emerging-air-sensor-performance https://www.epa.gov/air-sensor-toolbox/evaluation-emerging-a... 2: https://www.epa.gov/research-states/low-cost-air-quality-sensors-webinar-archive https://www.epa.gov/research-states/low-cost-air-quality-sen...
