Nowadays, air pollution has become one of serious problems in Taiwan. Compared with outdoors, indoors due to relatively small in space, may contain higher concentration of particulate matters (PM). In addition to the size of space factor, the humidity of indoors and outdoors may also play an import role on the concentration of PM. Therefore, we conducted this research to analyze the effect of indoor and outdoor humidity on the concentration of PM. We calculated the difference between indoor and outdoor humidity, and converted it into a line graph with the concentration of indoor PM2.5. And then we inferred that PM2.5 is definitely related to the difference between indoor and outdoor humidity and the concentration of indoor PM2.5. As mentioned above, we can not only learn about the connection between water and PM2.5, but also realize that water causes the deviation to the machine but it helps reduce PM2.5.

From your findings, if our goal is to minimize PM2.5 intake, do you recommend us to stay indoors or outdoors when humidity is high (or when outdoor-indoor humidity difference is high)?

When measuring, we also observed the concentration of outdoor PM2.5 at the same time. Discovering that no matter how humidity is, the concentration of outdoor PM2.5 was much lower than value we get indoor. If the indoor humidity become a little bit higher, it simply shorten the difference between both of them, but the concentration of indoor PM2.5 is still higher than the value we get outdoor. As a result, it will be a better choice to stay outdoor. However, those who need to stay inside for a long time such as students, the higher humidity cause minor harm to people.

The topic of this project is important and interesting. The explanation of PM2.5 is very nice. It's very good that you considered more than one inference and possible problems with the experiment. The citations and references are very well done. The line graphs are very nice. Overall, very nice project!
