PM2.5 - compared to?



  • Please tell me I am an idiot.

    Your PM2.5 unit measurements are regularly half of those found at PurpleAir or airnow.gov or https://enviwa.ecology.wa.gov/home/map, here in WA State USA, just for example.

    I have been trying to interpret your PM numbers for months.

    W H Y ? Which part am i not understanding

    RIGHT NOW: 58 mg/m3 Windy

    159 mg/m3 on average of PurpleAir meters.

    THANKS for helping me know whats gong on, or matching with these other websites (better!)

    thanks very much
