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 fil
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, andwherein 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. 2. The system of claim 1, wherein the at least one sieve screen comprises polyester. 3. The system of claim 2, wherein the at least one sieve screen comprises a polyester-based lofted material. 4. The system of claim 1, wherein the at least one sieve screen further comprises a tackifier applied to at least a portion of one side of the at least one sieve screen. 5. The system of claim 1, wherein said first filter causes no more than 5 mm Hg change in pressure in said ventilator. 6. The system of claim 1, wherein said breathing system is suitable for placement in fluid communication with the lungs of said subject. 7. The system of claim 6, wherein said breathing system is suitable for fluid communication with the lungs of said subject through a face mask. 8. The system of claim 6, wherein said breathing system is suitable for fluid communication with the lungs of said subject through an endotracheal tube. 9. The system of claim 1, further comprising at least one accessory. 10. The system according to claim 9, wherein the at least one accessory is a biological filter configured to reduce viruses or bacteria. 11. The system according to claim 9, wherein the at least one accessory is a liquid trap to remove liquid from the breathing system. 12. The system according to claim 9, wherein the at least one accessory is a heat sink configured to cool the breathing system. 13. A system for reducing the concentration of a dimethyl sulfoxide (DMSO) metabolite having an undesired odor, wherein the system comprises: a gas-line configured for fluid communication with the lungs of a patient;wherein the gas-line comprises a filter suitable for fluid connection to a gas exchange device; andat least one accessory,wherein the filter comprises:an adsorber comprising about 10 g to 100 g of activated carbon; andat least one sieve screen configured to allow an odor to pass through the filter while preventing the adsorbent from entering or exiting the filter,wherein the at least one sieve screen comprises a polyester based lofted material; andwherein said filter causes no more than a 10% decrease in flow in said fluid-line. 14. The system according to claim 13, wherein the at least one accessory is a biological filter configured to reduce viruses or bacteria. 15. The system according to claim 13, wherein the at least one accessory is a liquid trap to remove liquid from the gas-line. 16. The system according to claim 13, wherein the at least one accessory is a heat sink configured to cool the gas-line.
