▎ 摘　　要

NOVELTY - Graphene water purification filter core comprises a first-stage graphene polypropylene (PP) cotton composite filter element, a secondary graphene modified activated carbon composite filter element and a third-stage graphene modified activated carbon composite filter element. USE - Used as graphene water purification filter. ADVANTAGE - The core and purifier removes bacteria from tap water without increasing the nitrate and heavy metal components in the water, has high rate, easy to use and economical. The water treated by the water purification filter maintains the content level of each beneficial element with the untreated tap water, and the filtered water has a pH of 7.40, which is closer to the pH value of the human drinking water and more directly suitable for drinking. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for graphene water purifier comprising the graphene water purification filter including a first shell, where the first shell is provided with the water purifying filter core, water tank, water pump, water tank and the water purifying filter core is connected through pipeline and the pump is arranged between the water tank and the water purifying filter core. DESCRIPTION OF DRAWING(S) - The diagram shows a schematic representation of the graphene water purification filter core
