Review on Temtop Airing 1000 2nd Generation Professional: Top-Notch Air Quality Monitor for Enhanced Indoor Environments by Dan Bobbert

This is the last west coast wildfire of 2020. I have this to measure the quality of outside and inside air. 2.5 pm from 120 and PM 10 from 170 were measured outdoors. Indoors it measured 2.5 pm out of 30 and PM 10 out of 50 (HVAC had a MERV11 filter). I then upgraded my filter to MERV16 and placed a gauge next to the registers to test clean air, measured PM2.5 out of 3 and PM10 out of 5 (MERV16 filter). So it seems to measure exactly the particles that interest me. I expected and it comes in a nice lockable carry case. So far I am very happy with this counter.
