In this paper, we introduce the notion of anti fuzzy filter and study the \(\mathcal{N }\)-subalgebra(filter) of \(CI\)-algebra \(X\). We prove that every anti fuzzy filter of \(BE\)-algebra is an anti fuzzy subalgebra, but it is not valid in \(CI\)-algebra. Finally, the notion of fuzzy translations and fuzzy extension of anti fuzzy filter in \(CI\)-algebras are introduced. We show that every anti fuzzy filter can be as an anti fuzzy extension, but converse may not be true in general.
