1. A combustion process waste receptacle having a main passageway, a fluid contaminant passageway, a filter, and a fluid contaminant reservoir, said main passageway having an inlet port and an outlet port, said filter associated with said main passageway, said fluid contaminant passageway providing fluid connection between said filter and said fluid contaminant reservoir, said waste receptacle comprising:
a. a fluid lock associated with said fluid contaminant passageway and positioned directly below said filter, said fluid lock having an open state and a closed state, said fluid lock comprising:
i. a float chamber;
ii. a floatable float at least partially positioned within said float chamber and held therein by a flow-through retainer; and
iii. said fluid lock is in said open state when said floatable float rests on said flow-through retainer;
b. in said open state, said fluid lock allows passage through said fluid contaminant passageway; and
C. in said closed state, said fluid lock prevents passage through said fluid contaminant passageway;
d. wherein when said waste receptacle receives contaminated air at said inlet port, if said fluid lock is in said open state, fluid contaminants pass through said fluid lock and into said fluid contaminant reservoir, and if said fluid lock is in said closed state, fluid contaminants are prevented from passing through said fluid lock and into said fluid contaminant reservoir.
