How do filters affect air quality?
Can we measure reductions of Particulate Matter (PM) using natural materials as filters?
The Hypothesis: “I believe that the moss will absorb the most PM when compared to a wool, silk and industrial filter. To do this experiment I used particulate sensors and directed air over them and through a filter. This meant building filters and designing and building a testing unit.
In order to bring up the levels of PM as the air entered the tube, I lit incense. Data shows what we expect to see: the greatest average difference (or reduction) between the top and bottom sensors was with the moss filter.”
