S.K ENTERTAINMENT They are frauds
返信 23/09/2020BG541651125 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.
返信 19/01/2021BG516241834 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?
