Does it say what type of pollutant? PM2.5 is very different from SO2 which is different from O3, etc.

No it's just an LED that's either blue, orange, red. I knew it wouldn't give me exact figures (or pollutants) but from what I'd read the "fix" was to get an air purifier or move.

SO2 and O3 sensors are very expensive, so almost all sensors made for homes measure PM.

In that case it's almost certainly the highway. Tires are a massive source of PM2.5.

That's my main concern although maybe air pollution from toast / allergens is just as bad.
