Subject: HEPA-filtered enclosures
We are considering the purchase of a stand-alone HEPA-filtered work station, to make a semi-enclosed work area for removal of mold from (dry) library materials, particularly from archives collections in which mold is discovered during processing. The operator would be using a combination of brushes and a Nilfisk vacuum to capture the bulk of the mold, while the HEPA station would, we hope, trap any stray mold or other particulates. The setting would likely be the stacks or a manuscript processing area. I would be interested in hearing from anyone with experience using and maintaining these units, or any recommendations as to specific models or manufacturers. The one we are looking at right now is the Labconco Purifier HEPA-Filtered Enclosure, which is not vented to the outdoors, but passes air through a HEPA filter before recirculating it into the room.
