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 providing an improved reduced fiber filter.

Reduced fiber disk/shroud filter for removing contaminants from an enclosure

The invention relates to an improved electrostatic filter and filter media 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 providing an improved performance recirculation filter.

Recirculation filter

A compact sorbent filter for selectively sorbing contaminants and method of removing contamination from an enclosure with a filter is disclosed. Filters of the present invention comprise two or more modular adsorbent units that can be foldably connected and possibly symmetric about one or more axis. In another aspect, the invention provides a laminar support, having at least one edge, a first side and a second side opposite the first side, wherein the article is folded along the fold line about the at least one edge of the laminar support such that the first adsorbent assembly is adjacent to the first side of the laminar support and the second adsorbent assembly is adjacent to the second side of the laminar support. In this aspect, the laminar support may be exposed or covered by the adjacent adsorbent assemblies.

Modular adsorbent filters

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 improving performance and possibly incorporating multiple filtration functions into a unitary filter. The filter includes flow layers which improve filter performance. Filtration functions include a passive adsorbent assembly and can include a combination of inlet, or breather filter and adsorbent filter. Moreover, recirculation filter, diffusion tube and outside mount functions can be added to the filter depending on desired functionality within the enclosure.

Adsorbent breather filter

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 improving performance and possibly incorporating multiple filtration functions into a unitary filter. Filtration functions include a passive adsorbent assembly and can include a combination of inlet, or breather filter and adsorbent filter. Moreover, recirculation filter, diffusion tube, and outside mount functions can be added to the filter depending on desired functionality within the enclosure.
