[0002] A laboratory is a place where experiments are conducted. It is the cradle of science, the base of scientific research, and the source of technological development, playing a vital role in scientific and technological progress. Laboratories typically have environmental requirements; experiments cannot be conducted in environments with excessive dust or bacteria, necessitating constant air filtration. Application number 202111031058.9 discloses a laboratory air filtration device. The background art addresses the following problem: existing air filtration devices perform well in filtration, but they cannot be controlled by a system, requiring manual measurement, which is cumbersome.
