The present invention relates to filtering a collected sample for water analysis, and a device where filtered water is collected so that filtered water can be contained in a sample container and where the collecting rate of the sample can be controlled. The collecting device comprises at least one filter funnel part, an upper plate on which the funnel part placed, mounting means comprising a supporting rod wherein one side of the supporting rod is combined with the edge of the upper plate and a waste box fixing the supporting rod, several base container parts wherein the sample container is inserted and a outlet port is formed, and a vacuum pump connected to the vacuum connecting port by a pump tube. Accordingly, the step of transferring filtered water into the sample container can be omitted, and the collection time can be reduced by controlling the collecting rate of the sample.
