I bought this device to check the air quality in my house, I found that the amount of particulate matter produced in the house by things I did not think much about like incense, cooking, and even burning a candle !
Very simple operation, there is only one button, but the function is very complete. What is particularly surprising is the curve recording function, which can clearly display the changes in air quality in one day.
The design of this air quality monitor is super nice. It is not slippery at all and is not afraid of falling. The display is clear and easy to understand, I can switch between 3 kinds of modes to highlight the data I prefer. A useful device that gives insights into my environment that I didn't expect.
