A nebulizer comprising of an elongated body including a nebulized fluid emission opening at one end with a nebulizer fluid reservoir communicating with the opening and a fluid barrier means adjacent to the opening. A wick extends between the reservoir and barrier for conveying nebulizer fluid to the barrier region from the reservoir. A source of pressurized gas is within a housing along with a means for conveying the pressurized gas to the wick in the region of the barrier. The conveying means includes a perforated section which extends into the region of the wick and through the barrier. The pressurized gas traverses the conducting means and aspirates the nebulizer fluid during passage through the barrier. The perforated section is a helical spring and the wick is a carpet-like fabric. A novel form of perforated barrier in the form of a closely spaced helical spring is enclosed. A novel filter formed from a knurled rod within a passage also is disclosed.
