British Civilian Dummy Filter. This is a 3d printed replica of a filter used in WW2, only without the nasty stuff inside! Made from a biodegradable PLA black plastic, these 'filters' are designed to fit in place of the original filter. The bottom has a cloth layer to look like the original and has a rubber valve up top to allow a one way flow of air. I feel I need to point out that these are a replica of the original filter and not designed to protect you from anything harmful! I still don't think it is a good idea to wear these masks so I am selling these as a display prop only. Use at your own risk! Comes with a the main black container and the green filter taped together with cloth tape. No mask included.
