Abstract
A filter tube respirator having a filter tube and at least one breathing orifice interface. The filter tube is made of filtration material so that it is gas permeable, is substantially hollow, and has a pair of ends. The breathing orifice interface may include a nose piece, a mouth piece, and a flap piece. The filter tube has a tube breathing hole located between the ends for accepting the breathing orifice interface and has a tube valve hole opposed to the tube breathing hole for accepting a one-way valve. An attachment device selectively connects the filter tube to an individual during use.
