We discuss the $n$-fold implicative/fantastic filters in lattice implication algebras, which are extended notions of implicative/fantastic filters. Characterizations of $n$-fold implicative/fantas-tic filters are given. Conditions for a filter to be $n$-fold implicative are provided. Extension property for an $n$-fold fantastic filter is established.
