Abstract
The invention relates to a device for filtering contaminants, such as particulates and vapor phase contaminants, from a confined environment such as electronic or optical devices susceptible to contamination (e.g. computer disk drives) by incorporating multiple filtration junctions into a unitary filter. Filtration functions include a combination of inlet, or breather, filter and recirculation filter. Moreover, adsorbent functions can be added to the filter depending on desired functionality within the enclosure.
