Inventor includes Kikuchi, Yuta.
The application for the patent was published on October 30, 2026, under issue no. 44/2026.
Abstract: The present invention provides a filter in which a metal–organic framework is supported on a base material, the filter satisfying the following requirements (R1) and (R2) when air of high temperature and low humidity is made to flow at a prescribed air velocity through the filter that has been subjected to a specific pretreatment (a) and a water adsorption treatment (b). Requirement (R1): A graph P, of which the horizontal axis is time (s) and the vertical axis is the cumulative amount (g) of water desorbed per gram of filter, and a graph Q, of which the horizontal axis is time (s) and the vertical axis is the temperature (°C) of the air downstream of the filter, are each acquired, the time t (s) to reach the point T at which the temperature of the air downstream of the filter is lowest in the graph Q is ascertained, and the absolute value of the linear slope connecting the origin and the point (t, P(t)) on the graph P at time t is 9 × 10-4 or more. Requirement (R2): The cumulative amount of water desorbed after 600 seconds is 0.133 g or more per gram of the filter.
