Activated carbon - Fine pores and voids in the activated carbon particles can absorb and remove organic substances such as chloroform. Activated carbon can not only remove the smell of bleach in tap water but also absorb and remove trichloromethane from tap water. Keep the original minerals in filtered water PP cotton - Through the [hollow fiber membrane], use delicate high-precision hollow fiber membrane, highly remove bacteria, turbidity, etc. Hollow fiber membrane. Stainless steel mesh - Water, firstly filter through the activated carbon, use the activated carbon special effects, reduce oxygen consumption and absorption and remove volatile phenol, chloroform, carbon tetrachloride, and other organic matter. Hollow fiber membrane filtration - hollow fiber membrane filtration can be described as the heart of the device Polyethylene hollow fiber wall surface is even and meticulous, and can remove particles above 0.01-micron bacteria. ​The hollow fiber membrane can also completely remove Escherichia coli
