According to reports from relevant authoritative news media, in Europe, when air pollution is at its peak, Paris, France will even stop traffic operation; Singapore's air pollution has also reached an all-time high; India's air pollution is even more serious than China's.

In the indoor environment where we live, particulate matter is very common, such as smoke, cigarettes, candles, incense, etc. The concentration difference of these suspended particles within a few centimeters can reach 50% or more.
