One of the sockets (not shown) is connected to a water supply line, and the other is connected to a purified water outlet.

On the side surface of the transparent or translucent container 1, a packaging material 7 made of a resin sheet is shrink-wrapped. On the packaging material 7, a morphological pattern portion 8 is printed by appropriately combining characters, figures, symbols, or shapes, patterns, colors, and the like. In this example, a wave figure 9 having an appropriate color and a circular portion 10 in a bubble state in water are drawn, and the circular portion 10 forms a visual region 11 which is a part of the form pattern portion. ing. In the case of this example, a wave graphic and a bubble graphic are combined, and it is configured so as to represent the sea and have morphological integrity. In this case, the packaging material 7 is removed from the container 1 to enable recycling, thereby improving environmental performance. In addition to the above-described shrink wrapping, the form pattern portion 8 may be applied directly to the container 1 by means such as printing.

In the drawing, reference numeral 12 denotes a filter member, and a casing 12a of the filter member 12 is provided with pre-filters 14a and 14b made of a nonwoven fabric or the like, the bottom of which is closed by a cap portion 13 and the side surface of which is formed in a cylindrical shape. The fibrous activated carbon layer 1 is provided on the intermediate layer of the prefilters 14a and 14b.
4c and the granular activated carbon 15 in the casing 12a.
And a hollow fiber membrane 16 that communicates with the water purification outlet 4 at the center. In the drawings, 17a and 17b are seal members, 18 is an outer cylinder, and 19 is a potting portion.

Next, the operation of the above embodiment will be described. Drinking water or the like is injected from the tap water through the raw water inlet 3 and enters the container 1, and the raw water is filtered as a side flow from the side surface of the casing 12a of the filter member 12, and the casing 12
a of the prefilters 14a and 14b and the fibrous activated carbon layer 14
Prefiltered by c.

Next, while the chlorine component is removed by the granular activated carbon 15, fine particles such as particulate matter are surely filtered by the hollow fiber membrane 16 to become purified water and flow out from the purified water outlet 4. As described above, when the filtration by the filter member 12 is continued for a predetermined period, a clogging state occurs, and fine particles and dirt adhere to the outer peripheral surface of the pre-filter 14a located on the outermost side surface of the casing 12a. For example, the white pre-filter 14a turns brown. Since the discolored state of the pre-filter 14a can be visually checked from the viewing area 11, the replacement time can be easily confirmed by a simple structure based on the discolored state. By doing so, water can be purified continuously. In this case, the filter member 12 includes a three-layer pre-filter 14.
