The PM2.5 value released by the Meteorological Bureau is an average value, and it is also different from the data detected in different places where it is placed. For example, a total of 5 detectors are placed in Beijing (this is not necessarily true, it is estimated to be one in a small place), and then the total values ??are added together and divided by 5 to get the average value. This value is not necessarily the PM2.5 value of your home. Of course, if the detector is placed near the source of pollution, the level will be higher. On the contrary, if the detector is placed in a place where there are no sources of pollution, the level will be low.

To measure PM2.5 at home, you can put a Xiangchong PM2.5 detector. Although it is not as accurate as the industry, you can still know the air quality in your home. It can detect formaldehyde and PM2.5 at the same time. If the temperature and humidity exceed the standard, you will be reminded. Model: XCVOC-HP05
