Mass: 1 kg
This device provides a means for breathing in A3 environments by filtering toxic substances out of the air. It’s only effective in an atmosphere with an oxygen content and a pressure of P3 or P4. The mask requires no power, but its filter cartridge must be replaced after 48 to 96 hours of use, depending on the condition of the local air. Extra cartridges cost $25 each.
