Abstract:
1. A method for reducing the concentration of a dimethyl sulfoxide (DMSO) metabolite having an undesired odor, comprising: passing a DMSO metabolite through a breathing system in fluid communication with a subject, wherein the breathing system comprises a first filter, a ventilator and a HEPA filter in fluid communication, wherein the ventilator is configured 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 first filter, and contacting the DMSO metabolite with the first filter to capture at least 75% of the DMSO metabolite, thereby reducing the concentration of said DMSO metabolite.
