Is this legal?

I used my c-pap machine just a few times before my surgery ( I didn't get it long before) and not at all after. Can these be sold on E-bay? It seems that someone without insurance that needs one should be able to buy it really inexpensively from me. They could get a new mask, etc for the sake of sanitation. (I haven't totally paid for it yet.) I don't want to do anything wrong.

The only thing I see wrong with it is that typically a person is suppose have a prescription to use one. And here is a question to throw out there, if a person does not have insurance to cover the CPAP how did they have the sleep study done??? I know there might be other situations. The best thing would be if the person had a prescription, bought one off E-bay and took it in to get it set at the correct level for them.

I think you should pay for the machine before you sell it. For example, if you purchase a car, make monthly note payments and decide to sell it to a third party and don't pay off the lien holder which is the bank, that is illegal. The bank owns that car until the last note is paid in full.

It is legal. Usually it is someone without insurance that had to pay for everything themselves. The machine would require professional cleaning and adjustments. I know that some individuals once they have lost the weight and no longer carry the diagnosis of sleep apnea by repeat testing donate their CPAP at Sleep Care (Co.) for those that cannot afford it. But the pulmonary doctor there makes sure that it is cleaned, fitted and properly adjusted for them. Otherwise they would have a perfectly good machine sitting around. Of course these situations are unique and I do recommend that the CPAP machine be used until your pulmonary doctor says you no longer need it. The risks of sleep apnea untreated are quite serious. You will probably have sleep apnea, until you lose a significant portion of your weight and a few will continue to have mild sleep apnea even after the weight loss in stable.
