This past weekend I decided to test the latest model of the PICKLE—with the Plantower 5003 and the Particle Electron—by lighting an incense stick near the monitor. As you can tell, the PM2.5 levels jump from roughly 3.0 to about 130, which was quite alarming. However, in the grand scale of things, the air quality when burning the incense stick is still almost 8 times better than that of Beijing and New Dehli.
