SOLUTION: To provide a filter CF1 for filtering a dialysate comprising: a housing 52 for storing a filter medium 51 therein and whose longitudinal direction is a vertical direction; an introduction port 53 disposed on a lower part of the housing, and introducing the dialysate from an upstream passage 23a; a filtration liquid deriving port 54 for deriving the filtered dialysate which has passed the filter medium from an upper part of the housing to a downstream passage 23b; and a non-filtration liquid introduction port 55 for deriving a non-filtered dialysate to a liquid discharge passage 57 from the upper part of the housing, in which when the filter is removed from a dialysate circuit 4, liquid suction means 64A sucks the liquid from inside of the housing via the upstream passage, and air flowing means 65 makes air flow in the housing from at least one of the liquid discharge passage and downstream passage, and liquid is sucked from the downstream passage and air is made to flow from the upstream passage, or, the liquid is sucked from the liquid discharge passage and the air is made to flow from the downstream passage, for solving the problem.EFFECT: As an effect, a residual liquid in a filter is reduced.SELECTED DRAWING: Figure 2 |
