Just a tip for the military veterans out there. You can get almost all your CPAP supplies from the VA.
If you are not registered with the VA, get your DD214 and go there. You will have to fill out some paperwork, attend one orientation, see the primary care physician they assign you, and you're good to go. The PCP will hook you up with the right people, and they will do or order a sleep study for you if you haven't had one. If you have already had one, you will need to provide a copy of that to the VA. Now all I have to do when I need supplies (mask, headgear, filters, hose, water chambers, etc) is call them and it arrives via FedEx/UPS within 2 weeks. They will also provide you with a CPAP machine, and it isn't a cheap one.
It doesn't cost me a dime today, we've all prepaid for that with our military service. YMMV, as the VA classifies you according to your service and physical history. If you're a Vietnam Vet, with actual service IN Vietnam, you're gold. The only thing you're going to pay for is $8 a month for any Rx you get from them.
I get all my supplies and machines thru the VA also. Get sleep center here takes good care of me.
