    The invention relates to the protection of respiratory organs from harmful substances, in particular, to devices used during evacuation.
    The purpose of the invention is to improve the protective characteristics of the respirator while at the same time increasing the rate of its introduction into action.
    FIG. 1 shows a respirator with a protective helmet and a replaceable filter in FIG. 2 — a respirator and a respirator filter with a cutting edge.
    The respirator contains a mounting frame 1 fixed by a pipe 2, made on the back end wall of frame 1, on mask 3. Filter 4 is installed in the through channel of mounting frame 1, Seals 5 are located in the contact zone of the end walls of frame 1 and filter 4, compacted filter 4 respirators against extraneous penetration of air. In the inlet of the frame 1, which is formed in its front end wall, a protective filter 6 is installed. The filter 4 is installed with the possibility of its replacement by pushing out the replacement filter 7, Filters 4 and 7 are packed in a protective sheath 8, the side wall of the filters is designed as a cutting edge 9. The protective sheath 8 is provided with a fixing flange 10 placed on the mounting frame 1 opposite the cutting edge 9. The respirator can be equipped with a protective helmet 11.
    Air for breathing enters through the respiratory protection filter 6, where it is preliminarily purified, and through the side walls of the filter 4 into the respiratory organs. The replacement of the used filter 4 is carried out by inserting the replacement filter 7, which was securely packed into the protective shell 8, into the fixing flange 10,
    which is tightly set in kana32
    left on the mounting frame 1. When the used respirator filter is inserted or replaced, the cutting edge 9 simultaneously breaks the protective
    shell 8.
    Thanks to the simple insertion of the filter into the mounting frame, it is possible to use a respirator in case of a catastrophe and people.
    mi who do not have special training. In case of unforeseen, longer operation, it is possible to change the used filter without interrupting the respiratory protection, while ensuring the quick introduction of the respirator.
