NOVELTY - The utility model relates to the mechanical field, specifically relates to a filter core. A graphene composite functional filter core, comprising a filter core, the filter core comprises a supporting frame in a circular tube shape, the upper part of the supporting frame is provided with at least three uniformly distributed air holes. The utility model through the design, provides a graphene composite functional filter core, stable structure; convenient use; the design enhances the stability of the filter core mounting, convenient for the operator to install; at the same time, the graphene non-woven fabric layer improves the air filtering effect and effectively improves the bacterial pollution problem of the air, ensures the use effect of the air filter core.
