The bipolar-valued fuzzy filter in Sheffer stroke BL-algebras is defined, and several properties are investigated. Various characterizations of the bipolar-valued fuzzy filter are discussed. It is shown that the intersection of bipolar-valued fuzzy filters is also a bipolar-valued fuzzy filter, and an example to show that the union of bipolar-valued fuzzy filters is not a bipolar-valued fuzzy filter is provided.
