I purchased 70 different PNC3s(mostly Transportation) at
ebay from a seller and when they arrived I opened the glassine envelopes I began smelling cigarette smoke, laid them out on a table and the cigarette
smoke smell was/is so strong my eyes burned and I broke out in a rash. I read thru the above to get some ideas to get rid of this irritating smell. I was thinking if I got a commercial O3 (Ozone) generator and place the stamps and generator in a small unoccupied room detached from my home behind closed doors (not safe to breath O3) would that work much better. I understand car dealers put them in used cars and all odors are eliminated including heavy smoke and I am told others have used the generators to eliminate virtually (so claimed by mfg) ANY mal-odors from mold, cigarette/cigar smoke, pet odors, paint/cleaning fumes, dust, water damage, smoke damage, cooking odors, and other airborne irritants, and they help to eliminate and retard mold, mildew, and fungus growth....all types of smells. I am told an Ozone generator works on a different principal than an air freshener which is what others seem to be suggesting. I have been told when contaminants such as odors, bacteria or viruses make contact with ozone, they are destroyed completely by oxidation. In so doing, that extra atom of oxygen is consumed and there is nothing left...no odor...no bacteria...no extra atom, only oxygen, so I am told. Ozone reverts back to oxygen after it is used. Of course one has to follow the FDA guidelines and this would not be safe to use in living space. Has anyone tried this method?
