An axi-symmetric adapter is provided for attaching to a pre-filter bag as a pre-filter assembly for use with chemical, biological, and radiological filtration systems. The bag has an annular retention ring, with the assembly being insertable into a cavity of an M98 Filter Bank or other Navy-designated Collective Protection System filter housing. The adapter includes tang, groove, flange mezzanine rings. The tang ring has an exterior bevel edge and terminates a reverse side of the adapter. The groove ring possesses inner and outer cylindrical walls that define a circular channel and terminate an obverse side of adapter. The flange ring extends radially inward from the inner cylindrical wall for engaging the retention ring. The mezzanine ring connects the flange and groove rings together.
