Definitions for different particle size ranges

Data
1

Hello,
As part of one project, we used 2 PurpleAir Zen Air Quality Monitor to collect particle concentration data. I needed clarification on the particle size ranges represented by the 6 mass channels: PM0.3, PM0.5, PM1, PM2.5, PM5, and PM10 particles. I would greatly appreciate it if you could provide me with the definitions you use for these 6 categories of sizes.

Thank you very much
