The meter has a nice screen and a reasonably accurate dust counter. I compared it's results to the CARB air monitoring station a few blocks away and found that it usually reads 10-20 points lower up to AQI 150. At higher values it becomes less accurate often reading much lower than actual. However the main reason I bought it was to compare indoor and outdoor pollution levels to see if my air filters were working during the California wildfires and the meter works very well for that purpose. It's low power consumption means be powered from a USB power back to turn it into a portable monitor that lasts for many hours. The meter needs to sit in an area undisturbed for 10 minutes before taking readings. I wish it had some way of outputting the data over USB so I could log the results over time. I also discovered that it's really important to always run the vent fan in the kitchen while cooking as it can get quite polluted in there.

  • BG541651125 Hi.As you have compared your PM2.5 monitor to an accepted standard, can you please tell me what readings you got in a normal house room. I am not sure if my PM2.5 is working as the readings are consistently between 0 and 4, mostly 0. I don't have a particularly dust free house. Thanks.

  • BG516241834 Hi I have the same issue as the other reviewer. The reading in my house is always 0-4. Right now the AQI outside is about 100. I\'m in the bay area not far from the fires. This can\'t be working, right?
