A melter, comprising:

• a housing defining a receiving space configured to support adhesive therein;

• a vent that extends through a wall of the melter and that is configured to permit the transport supply gas to escape from the melter;
• a filter medium supported in the vent, the filter medium configured to capture particulates from the transport supply gas escaping the receiving space, and positioned relative to the receiving space such that heat from the receiving space causes the particulates captured by the filter medium to melt and fall into the receiving space;
