FIELD: means of protection.
SUBSTANCE: device for protection of respiratory system includes protective cap made from flexible gas-tight material which is equipped with neck sealing. In the cap there installed are cartridges with regenerative product. Cartridges are fixed symmetrically on opposite walls of cap and connected along edges to fans connected to power unit through switch. On one of the cartridges there fixed is starting device which is also connected to power unit. In cavity of cap there installed is cooler so that gap between rear wall of cap and wall of cooler is formed. Cooler is made in the form of screen with connecting strips. At that, inlet of fans is located from the side of respiratory system of user.
