Improved multi-functional molded filter for removing contaminants from an enclosure

摘要

The present invention is an improved molded filter which performs multiple filtration functions within an enclosed environment, such as within a computer hard disk drive. In a first embodiment, the filter is capable of removing particulate contaminants from both incoming (external) air and recirculating air by performing both breather and recirculation functions when placed over a breather hole in a disk drive. In an alternative embodiment, the filter also incorporates an adsorbent material which allows it to remove both particulate and vapor phase contaminants from incoming (external) air and recirculating air within the disk drive.
