A pendent-type diffuser impingement water mist fire protection nozzle has a body defining an orifice and an outlet for flow of fluid from a source, and a diffuser positioned for impingement of the flow of fluid thereupon, the outlet and diffuser being disposed generally coaxial with the orifice. The diffuser defines an inner surface opposed to water flow from the outlet and an opposite outer surface. The diffuser inner surface defines a generally horizontal base area facing the nozzle outlet, an outer area spaced radially outwardly from, and disposed further from the outlet relative to, the base area, the outer area defining a generally continuous, circumferential peripheral edge, and an intermediate region extending between the base area and the outer area, the intermediate region defining a slanted surface disposed at a predetermined acute angle to the horizontal. The slanted surface defines a plurality of through holes from the inner surface of the diffuser to the opposite outer surface.
