NOVELTY - The utility model claims a composite filter core, comprising a filter core shell; the filter core shell is formed with a filter cavity; the filter core shell is formed with a total water inlet and a total water outlet; the inner part of the filter cavity is provided with an ultrafiltration component and an active carbon rod; the ultra-filtration component is provided with a first water inlet and a first water outlet; the active carbon rod is installed in a cylinder; the active carbon rod is separated from the raw water by the cylinder; the cylinder body is provided with a second water inlet; the second water inlet is connected with the first water outlet of the ultra-filtration component; the inner part of the active carbon rod is connected with a water outlet pipe; the water outlet pipe is connected with the total water outlet. The ultra-filtration component of the utility model has high efficiency of sterilizing effect, and graphene active carbon rod has good bacteriostatic effect, with double sterilizing effect, ensuring the quality of the filtering water; At the same time, the graphene active carbon rod good bacteriostatic effect, can effectively reduce the secondary pollution of the composite filter core.
