A: PM2.5 data are changing at all times, with the air, wind, humidity and other environmental factors change, in
the room smoking, cooking fumes, car exhaust emissions, coal, chimney, furnace Such as pollution sources will
change the PM2.5 value of this area, resulting in differences in the detection data.

Q: Why is the product sounding when working?
A: PM2.5 detection need to collect a lot of mobile air, in order to ensure accurate detection of the fan needs
strong operation, so a little sound is normal.
