There's either a typo or something wrong with your sensor: you can't have pm10 < pm2.5.
(Equivalent to saying you have more people under 2.5 years old than under 10 years old.)

Transcription error there, you’re right, from Airgradient.
What? pm2.5 is smaller than pm10. You can have a bunch of larger particles that aren't small
pm10 is the mass concentration of particles with aerodynamic diameters up to approximately 10 µm, including PM2.5, so Jefftk's analogy was right. there must some kind of typo or measurement error
