ABSTRACT:
A filter wrap for a cylindrical filter has a sheet with an interior side facing the filter when the sheet is wrapped on the filter, and an exterior side. It also has an edge defining a main opening to the interior for receiving the filter. At least one strap is provided for the wrap with one end attached to the sheet. The strap has another accessible distal end. Pulling on the strap(s) everts the sheet as it is pulled off of the filter. This results in trapping debris residing on the exterior of the sheet within the sheet once it is everted during removal of the wrap from the filter. Installation and removal can be performed while the protected equipment remains in operation.
