Abstract:
1. A system for reducing the concentration of a dimethyl sulfoxide (DMSO) metabolite having an undesired odor, wherein the system comprises: a breathing system suitable for placement in fluid communication with a subject comprising: a first filter; a ventilator; and a HEPA filter, wherein said first filter, said ventilator, and said HEPA filter are suitable for placement in fluid communication with one another, wherein the ventilator is suitable for transporting moist air comprising said DMSO metabolite from a subject to an exhaust port, wherein the HEPA filter is positioned between the subject and the filter, wherein the first filter is positioned downstream of the HEPA filter, wherein said first filter causes no more than a 10% decrease in air flow and no more than a 10% change in pressure in said ventilator, wherein the first filter comprises an adsorber and at least one sieve screen, wherein the adsorber comprises about 10 grams to about 100 grams of activated carbon, wherein said at least one sieve screen is configured to allow said DMSO metabolite to flow through the first filter while containing the adsorber within the filter, and wherein contact of the DMSO metabolite with the first filter allows the first filter to capture at least 75% of the DMSO metabolite, thereby reducing the concentration of said DMSO metabolite having an undesired odor.
