ABSTRACT:
Stripping contaminants/impurities from a filter includes subjecting the filter to a negative gauge pressure and applying superheated solvent vapor to the filter while maintaining the negative gauge pressure. The filter can be heated prior to being subjected to the negative gauge pressure. The superheated vapor may be composed of the same compounds as impurities being removed from the filter. The filter may be an activated carbon filter.
