    • The filter assembly of the present invention provides protection to a data storage disk drive assembly from contaminants, including chemical gases and particles, that either enter or exit the disk drive assembly. Incoming gases and particles pass through a label, into a hard body filter, through a diffusion filter, contact the chemical adsorbent and pass into the drive interior through a particulate filter. Outgoing gases and particles go through the apparatus in reverse. The filter assembly may be installed from the outside of the disk drive assembly at a chosen location and at any point during or after manufacturing and testing. The filter assembly is held in place by lateral extensions and an adhesive label applied to the exterior mounting surface.
