The notions of (strong) intersection-soft filters in -algebras are introduced, and related
properties are investigated. Characterizations of a (strong) intersection-soft filter are
established, and a new intersection-soft filter from old one is constructed. A condition
for an intersection-soft filter to be strong is given, and an extension property of a strong
intersection-soft filter is established.
