Abstract
A data storage system with a breather filter is provided. The enclosure of the data storage system has a first end and a second end and includes a least one disc adapted to rotate in a rotational direction. The second end further includes a first corner and a second corner wherein the second corner is downstream from the first corner relative the rotational direction of the disc. A recirculation filter is spaced radially outward from the disc and disposed between the disc's outer diameter and either the first corner or the second corner. The breather filter is disposed radially outward from the disc and downstream from the recirculation filter relative to the rotation of the disc in a negative air pressure region.
