Description

However, the aforementioned filter material has considerable weight, is inconvenient to carry and occupies space, and the filtration is not necessarily effective.

Of course, there are also related water and liquid filtration devices such as reverse osmosis. However, it is not easy to obtain power in the suburbs. Unless otherwise prepared, there may still be a dilemma that the power is exhausted and cannot be used.

In particular, the problem to be solved by the present invention is that when multi-layer paper is produced, it needs to be completed through multi-layer bonding technology and complicated procedures, and the overall production efficiency is low. In addition, so far, water source filtration in the suburbs has mostly used charcoal, medical stone, ... and other related filter materials for preliminary filtration of the water source. However, the aforementioned filter materials all have considerable weight, and the filtration is not necessarily effective.
