The pre-filter 1 comprises a first PP cotton layer 4, a pre-activated carbon layer 5, and a second PP cotton layer 6. Both the water-facing and water-exit surfaces of the first PP cotton layer 4, the pre-activated carbon layer 5, and the second PP cotton layer 6 are wavy. This wavy structure increases the effective area of ​​the filter layer for filtering tap water, thereby increasing the flow rate of water that can be purified simultaneously, and thus increasing the purified water flow rate. The post-filter 3 comprises an RO membrane layer 7, a post-activated carbon layer 8, and a third PP cotton layer 9. The water-facing end of the RO membrane layer 7 is wavy to accommodate the large flow rate of water purified by the pre-filter 1.

The first PP cotton layer 4 filter core mainly filters the incoming raw water, and can remove mud, rust, solid pollutants and the like in the water. The pre-activated carbon layer 5 filter core can adsorb color, odor, chlorine and other substances harmful to human body in the water. The second PP cotton layer 6 filter core purifies bacteria, chemical pollution, heavy metals and other impurities in the water. After the treatment of the first three filter cores, part of the larger impurities in the water have been removed, and the RO membrane layer 7 mainly removes other small pollutants in the water except pure water, such as bacteria, viruses, residual chlorine and the like. The post-activated carbon layer 8 mainly continues to adsorb residual odor and color in the water. The third PP cotton layer 9 is used to block the carbon powder and the like that may be generated by the post-activated carbon layer 8.
