Portable Home Oxygen Generator Machine - Quiet & Efficient Oxygen Concentrator for Sleep, Travel & COPD Relief - Perfect for Bedroom, Office & Emergency Use

My old oxygen concentrator quit working after 12 years of use. I was referred to a sleep specialist and I would have had to sleep in a hospital room for a night, all wired up, no fans or air circulation, no sleep aids and then to top it off they would not accept my insurance plan. There is no way I could sleep under those conditions. Sounded like a horrible night with my husband dropping me off at night and picking me up in the morning while driving an hour round trip each time. I found this with no Rx needed and it works great for me. I live at high altitude at 6300 ft elevation. The oxygen is constant flow. I paid out of pocket and the price was very reasonable. The size makes it travel friendly.
