Abstract
The present invention relates to a high capacity gas filter system. The metal filter of the system includes a visible indicator which indicates when the filter is spent. The indicator is preferably a non-reactive glass tube with indicator material therein. The glass tube can be protected to maintain gas flow integrity in case the glass tube breaks. The filter is attachable to or removable from its connecting base using a cooperating threaded knob and threaded bolt such that the filter is pulled tightly onto the base and forced off of the base depending on how the knob is rotated.
