The air purifier filter includes: a filter body having an inlet and an outlet therein such that air flows therethrough, and a receiving space having formed therein; a substrate provided in the receiving space of the filter body; and activated carbon attached to a surface of the substrate, wherein the substrate has a three-dimensional corrugated structure.

Abstract: The present application relates to a system, device, and method for monitoring an abnormal state of pipe, which monitors whether a pipe is abnormal. In the present application, a pipe state signal input from each signal acquisition part is divided into a plurality of time periods, and then it is determined whether an abnormal state signal exists in the pipe state signal in each of the time periods. Therefore, the present application enables determination with higher accuracy of whether the pipe is abnormal, compared to the case of determining whether an abnormal state signal exists in a pipe state signal which has not been divided into a plurality of time periods.
