I reached out to the author and they're using an uHoo Smart Air Monitor and will be writing a review of it in the future. Most reviews of air quality monitors seem to focus on details like the size of the screen, or whether the monitor app is easy to use, and fail to actually test the accuracy of monitor itself. Hopefully this author's review is different.

See this EPA testing table for some measures of accuracy: https://www.epa.gov/air-sensor-toolbox/evaluation-emerging-a...

So, there are basically no consumer products on this table that have a respectable accuracy, right? The ones with good R² values all seem to be $1000+ scientific tools.

Unfortunately, yes. And I wouldn't trust the uHoo marketing claims about their sensor even one bit.

I found another testing table if you'd like to take a look: https://www.cabq.gov/airquality/documents/research-on-availa...
