Also PM2.5 is easy to filter out. Any cheap device can filter it out quite efficiently.

For NO2 I tried all the most expensive devices, and none of them worked :(

This might be a silly question, but how would you filter stuff "emitted" by tyres?

I'm not a scientist, just an asthmatic person. All I can tell you is that I am so far not sensitive to electric cars at all.

Regarding PM2 and NO2, I bought decices to measure them, that's why I have these results.
