Is it actually possible that the AQI numbers my purpleair unit is reporting can be pretty stable in the 150s for two full days? It’s been smoky here. Other people’s sensors seem stable too. But before this I was seeing at least some variation up or down. I’ve only had the sensor for a month so I’m new to this and just want to know if this is normal. Thanks!

If you have good agreement with other nearby sensors, then your air may just be homogeneously polluted, and the reading is correct. My personal experience with wildfire smoke is that its pretty well distributed and if there isn’t any wind to move it out, it just hangs around.
