Abstract This project focused on 𝜃-filters in ADL and characterize it in terms of almost distributive lattice congruence. A 𝜃-Prime filters are also characterized in terms of prime filters, 𝜃-filters and prime –𝜃 filers in ADL. Some properties of 𝜃-filters and 𝜃-primes are also discussed. Furthermore a class of 𝜃-filters be can made in to bounded distributive lattice.
