The notion of Interval Valued Fuzzy Sets (IVF sets) was introduced by T. K. Mondal. In this paper a notion of IVF filter is introduced and studied. A new notion of Hausdorffness, which can not be defined in crisp theory of filters, is defined on IVF filters and their properties are studied.
Keywords: IVF sets, IVF filter, Hausdorff IVF filter, convergence IVF filterly, IVF filter continuous, IVF filter open, quotient IVF filter, product IVF filter
