Abstract
A sorbent breather filter for an electronic device such as a hard disk drive (HDD) is configured with a first chamber for housing a first sorbent and environmentally coupled with an external environment via at least a first orifice and a second orifice, a corresponding replaceable first sorbent such as zeolite or silica gel beads in the first chamber, a second chamber adjacent to the first chamber for housing a second sorbent, and a corresponding second sorbent such as carbon beads in the second chamber. The first orifice is a through-hole such that the first sorbent can be loaded into the first chamber therethrough, and the second orifice is a slitted or grated hole such that the first sorbent cannot move from the first chamber to the external environment through the second orifice while loading sorbent into the first chamber through an HDD first cover breather hole.
