1. A membrane oxygen humidifier comprising: at least one water permeable membrane;an enclosure having an air inlet port and an air outlet port, wherein the at least one water permeable membrane extends through the enclosure; anda fan positioned proximate at least one of the air inlet port and the air outlet port, wherein the fan directs air flow past a surface of the at least one water permeable membrane. 2. The membrane oxygen humidifier of claim 1, wherein the water permeable membrane comprises a hollow fiber membrane, a flat sheet membrane, a spiral wound membrane or combination thereof. 3. The membrane oxygen humidifier of claim 1, and further comprising: an air inlet port cover that is capable of substantially covering the air inlet port; andan air outlet port cover that is capable of substantially covering the air outlet port. 4. The membrane oxygen humidifier of claim 3, wherein at least one of the air inlet port cover and the air outlet port cover are operably attached to the membrane oxygen humidifier to automatically move from an open position to a closed position when the fan is engaged to direct the air across said membrane device. 5. The membrane oxygen humidifier of claim 4, wherein at least one of the air inlet port cover and the air outlet port cover is biased to a closed position and wherein force generated by air movement from the fan causes the at least one of the air inlet port cover and the air outlet port cover to move to an open position. 6. The membrane oxygen humidifier of claim 1, and further comprising a switch to activate and deactivate the fan, wherein the switch is manually operable, operable based upon sensing flow of gas through the water permeable membrane or combination thereof. 7. The membrane oxygen humidifier of claim 1, and further comprising a supplemental humidification source that is positioned proximate to the air inlet port and distal to the air inlet of the oxygen concentrator air compressor. 8. The membrane oxygen humidifier of claim 7, and further comprising a hood that at least partially encompasses a region between the supplemental humidification source and the air inlet port. 9. A oxygen delivery system comprising: an oxygen source;a membrane oxygen humidifier comprising: at least one water permeable membrane;an enclosure having an air inlet port and an air outlet port, wherein the at least one water permeable membrane extends through the enclosure; anda fan positioned proximate to at least one of the air inlet port and the air outlet port;a patient interface; andtubing interconnecting the oxygen source, the membrane oxygen humidifier and the patient interface. 10. The oxygen delivery system of claim 9, wherein the oxygen source is an oxygen concentrator. 11. The oxygen delivery system of claim 9, wherein the water permeable membrane comprises a hollow fiber membrane, a flat sheet membrane, a spiral wound membrane or combination thereof. 12. The oxygen delivery system of claim 9, wherein the water permeable membrane has a selective membrane with a greater selectivity for water over both nitrogen and oxygen. 13. The oxygen delivery system of claim 9, and further comprising: an air inlet port cover that is capable of substantially covering the air inlet port; andan air outlet port cover that is capable of substantially covering the air outlet port. 14. The oxygen delivery system of claim 13, wherein at least one of the air inlet port cover and the air outlet port cover are operably attached to the membrane oxygen humidifier to automatically move from an open position to a closed position when the fan is engaged. 15. The oxygen delivery system of claim 13, wherein at least one of the air inlet port cover and the air outlet port cover is biased to a closed position and wherein force generated by air movement from the fan causes the at least one of the air inlet port cover and the air outlet port cover to move to an open position. 16. The oxygen delivery system of claim 10, and further comprising a switch to activate and deactivate the fan, wherein the switch is manually operable, operable based upon sensing flow of gas through the water permeable membrane or combination thereof. 17. The oxygen delivery system of claim 10, and further comprising a supplemental humidification source that is positioned proximate the air inlet port. 18. The oxygen delivery system of claim 17, and further comprising a hood that at least partially encompasses a region between the supplemental humidification source and the air inlet port. 19. The oxygen delivery system of claim 10, wherein the patient interface is a nasal cannula. 20. The oxygen delivery system of claim 10, wherein the membrane oxygen humidifier is intermediate the oxygen source and the patient interface.
