1. A filtration assembly comprising:
(a) a sample reservoir for holding a fluid sample to be filtered, the sample reservoir having an open top end, an open bottom end, and at least two inwardly facing arms arranged at the open bottom end, the sample reservoir having an elastic side wall;
(b) a fluid port in fluid communication with the sample reservoir;
(c) a porous microorganism-capturing filter element disposed across a flow path between the sample reservoir and the fluid port, the porous microorganism-capturing filter element being releasably retained by the at least two inwardly facing arms;
(d) an absorbent pad arranged below the porous microorganism-capturing filter element and the at least two inwardly facing arms, disposed across the flow path between the sample reservoir and the fluid port;
(e) a base detachably mounted to the sample reservoir, the base including the fluid port, and a support surface for supporting the absorbent pad;
wherein compressing the elastic side wall releases the porous microorganism-capturing filter element from the at least two inwardly facing arms after the base is detached from the sample reservoir.
