     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT  
       [0011]    Referring to FIGS.  2  to  4 , the water filtering assembly of the present invention comprises a cup-shaped member  3  having a space  31  therein for receiving water filtering agent  32  and a top annular connection portion  33  and a bottom annular connection portion  34  are respectively connected to a top and a bottom of the cup-shaped member  3 . A filtering screen  342  is located at an opening of the bottom annular connection portion  34 . The cup-shaped member  3  is made of transparent material.  
         [0012]    A top cap  4  has an annular flange  42  on a top of the top cap  4  and a skirt portion  41  which is threadedly connected to the top annular connection portion  33  with a seal  35  located therebetween. A passage  421  is defined through the annular flange  42  and in communication with the space  31  in the cup-shaped member  3 .  
         [0013]    The cup-shaped member  3  is received in a container  2  that has various diameters and a recess  22  is defined n the container  2  so that the users may see the water filtering agent  32  via the recess  22  through the transparent cup-shaped member  3 . A top shrunk engaging portion  23  and a bottom shrunk engaging portion  24  are connected to a top and a bottom of the container  2 . A bottom cap  5  is threadedly connected to the bottom annular connection portion  34  of the cup-shaped member  3  and two stop flanges  52  extend inward from an inner periphery of a center hole  51  of the bottom cap  5 . A first connection piece  53  is connected between the bottom annular connection portion  34  of the cup-shaped member  3  and the bottom cap  5 . A shank  531  of the first connection piece  53  extends through the center hole  51  of the bottom cap  5  and the first connection piece  53  is stopped by the stop flanges  52  of the bottom cap  5 . A through hole  532  is defined through the first connection piece  53 . The bottom cap  5  is threadedly connected to the bottom annular connection portion  34  of the cup-shaped member  3 . Referring to FIG. 4, an threaded outer periphery is defined in the shank  531  of the first connection piece  53  and the shank  531  is connected to a hose (not shown) which is connected to a source of water supply.  
         [0014]    A top cover  6  is connected to the annular flange  42  of the top cap  4  with a seal  43  located therebetween. A second connection piece  63  with a through hole is connected between the annular flange  42  and the top cover  6 . Two stop flanges  62  extend from an inner periphery of the center hole  61  of the top cover  6  so that the second connection piece  63  is limited by the stop flanges  62  of the top cover  6  which is secured to the top shrunk engaging portion  23  of the container  2 . A threaded inner periphery  632  is defined in a shank  631  of the second connection piece  63  and a seal  64  is received in the shank  631  which is connected to a faucet  8  as shown in FIG. 4.  
         [0015]    It is to be noted that the shank  531  and  631  may have threaded inner or outer periphery as needed, and wave-shaped threads (not shown) may also be employed in the shank  531 / 631  of the first and the second connection piece  53 / 63 .  
         [0016]    The disengagement of the parts of the assembly is easy and the water filtering agent can be seen by the users who may replace new filtering agent without any delay.  
         [0017]    While we have shown and described the embodiment in accordance with the present invention, it should be clear to those skilled in the art that further embodiments may be made without departing from the scope of the present invention.
