Patent ID: 8298320

Claim:
A method for reducing the undesired odor associated with one or more metabolites of dimethyl sulfoxide (DMSO), comprising: transporting, via a medical ventilator, DMSO metabolite-containing air comprising one or more DMSO metabolites through said medical ventilator in use by a subject that has been treated with DMSO, wherein said medical ventilator comprises a first filter comprising a chemical odor removal layer and a HEPA filter, wherein the ventilator is configured to receive said DMSO metabolite-containing air, wherein the first filter comprises an adsorbent configured to adsorb said one or more DMSO metabolites from said DMSO metabolite-containing air, wherein said adsorbent comprises activated carbon, and capturing an amount of said one or more DMSO metabolites sufficient to reduce the associated odor by contacting said DMSO metabolite-containing air with said first filter, thereby decreasing the concentration of said one or more DMSO metabolites passing through said ventilator.
