Our take
The AirVisual Pro puts the inside and outside air side by side: PM2.5 and CO₂ from its own sensors, and the nearest station's reading from IQAir's network. That makes the daily decision easy. If the outdoor figure is lower, open up; if it's higher, keep the windows shut and the purifier on.
It measures fewer things than the Airthings or Qingping monitors, but it measures the two that matter most on a smoggy day.
Good for
- Deciding when it's better to open the windows
- Tracking PM2.5 and CO₂ from one screen
Skip it if
- You want radon or VOCs as well: the Airthings View Plus covers them

How we judge. We haven't tested the AirVisual Pro in a lab of our own. The figures come from independent ratings (AHAM, Energy Star, NIOSH, the ASPCA) or the maker, and the verdict is ours, from those figures. No brand pays to be listed. Last checked Nov 7, 2026.
