Abstract: A respirator which has a collapsible air guide (2) and two filter supports (3), the filter supports (3) each having a first end (35)=joined to the first end (35) of the other, and a second end (36) opposite to the first end (35). The air guide (2) is in a collapsed state when second ends (36) of the filter supports (3) are adjacent to one another, and is in a deployed state when the second ends (36) are further apart. The air guide (2) may be located between the filter supports (3) when the second ends (36) of the filter supports (3) are adjacent to each other.
