The invention discloses a PM2.5 double-purpose dust protection mask and a manufacturing technology of the mask, and belongs to the technical field of occupational health supplies. A pressing type individual dust protection mask comprises a nasal bracket, a tract groove I, an outer cover rotating shaft, a dust blocking filter membrane I, hang lugs or a safety cap connecting piece I, an outer cover, a sealing clamping buckle, a bottom frame and a sealing layer; and the outer edge of the inner side of the nasal bracket and the outer edge of the inner side of the bottom frame are of rough protruding structures. A tract type individual dust protection mask comprises an outer side supporting piece, a nasal inner sealing layer, a right face inner sealing layer, a left face inner sealing layer, a tract groove II, a tract handle, a dust blocking filter membrane II, and hanging lugs or a safety cap connecting part II; and the outer side supporting piece is connected with the nasal inner sealing layer, the right face inner sealing layer and the left face inner sealing layer. According to the mask, a relatively flexible dust protection manner can be provided for workers, in the area with the higher dust concentration, the good dust protection effect is achieved, and in the low dust concentration site, the requirement of workers for the oxygen intake amount is met.
