A water filtration device comprising:

• first and second like hollow elongated members, each member having a small opening in one end and a large opening in the other end, the large openings in both members being adapted for detachable engagement with each other, said members when engaged defining an elongated housing having a cylindrically shaped central section and opposite upper and lower ends with small openings therein;
• a single cylindrically shaped filter disposed removably in said central section, said filter having an axial bore aligned with the axis of said section, said housing end openings being centered on said axis, the ends of said filter disposed transversely to said axis having openings spaced from said bore;
• first means secured to the opening in the upper housing end and detachably securable to the discharge port of a water faucet to secure said upper housing end in a rotationally pivotable manner to the port and to conduct water downwardly from the port into the housing;
• and
• second means in the housing and connected between the first means and the bore, said second means having a first position with respect to said housing at which the conducted water flows downwardly through said bore and out of the lower end of the housing in unfiltered state and having a second position at which the water flows through the openings in the filter end adjacent the first means spaced from the bore, the filter, the openings in the opposite filter end spaced from the bore and out of the lower end of the housing in filtered state, the second means being placed in the first position when the housing is rotated in one direction about the first means and being placed in the second position when the housing is rotated in opposite direction about the first means.
