What is gp 5?

GP 5 refers to the type of gas mask filter used in the Soviet Union and its allies during the Cold War era. The filter is designed to protect against various harmful gases and particulates, including tear gas, smoke, and radioactive fallout. The filter is made up of activated charcoal, which removes gas molecules from the air passing through the filter. The GP 5 filter is easily recognizable due to its distinctive black color and kidney-shaped design. While the GP 5 filter is no longer widely used due to its age and limited effectiveness against certain gases, it remains a popular item among collectors of military memorabilia and survivalists. It is important to note that some GP 5 filters produced in the Soviet Union may contain asbestos, a deadly substance that can cause lung cancer and other respiratory diseases. As such, it is crucial to seek guidance from safety experts before using any old GP 5 filters.
