Devilbiss 525DS Oxygen Concentrator

See Details
If you are purchasing a new CPAP, Auto CPAP or BiLevel (BiPAP) machine, humidifier or an oxygen concentrator, then federal law requires that we receive a copy of a prescription written by your doctor. A sleep study report does not qualify as a prescription.  Also, the purchase of complete CPAP masks does require a prescription.  (*** Note that the component parts that make up the mask DO NOT require a prescription! ***)
The prescription must state that it is for CPAP therapy and at what pressure your machine should be set. If you are purchasing a standard CPAP machine (one that operates at a constant pressure), then the prescription must show one pressure setting, which is generally a number between 4 and 20 and measured in cm of H2O. If you are purchasing an Auto CPAP machine, then your prescription must state two different pressures: A low (minimum) pressure setting and a high (maximum) pressure setting. If you are purchasing a BiLevel machine, then your prescription must state two pressure settings: An inspiratory (IPAP) setting and an expiratory (EPAP) setting.  If you are purchasing an Oxygen Concentrator, the prescription should have the flow rate stated in Liters per minute. 
Prescriptions can be faxed to us at 888-469-2555, or we can accept a scanned copy of your prescription by emailing it to us at [email protected].

Please note that orders for machines, concentrators, or complete masks will NOT be shipped until we receive a copy of your prescription!

This is the best oxygen machine and the best value too ... i have had several of them and they are very reliable machines ... just be sure and CHANGE THE AIR INTAKE FILTER (it uses the MC44D-605 Intake Filter) EVERY 12 months - do NOT waite 24 months like the mgf recommends ... that is too long and if you are in a moldy area you may have some mold in it by then .. so be SAFE and do it every 12 months ..

I'm always a little weary of buying things on line, especially at such a great price this was, but once I got it home and hooked up it worked great and very quite. I would defiantly recommend this to a friend. Thanks Best CPA Price

I have had a concentrator for about 6 years. We bought this one as a stand by. I like it better than my other one as it is smaller & quieter.The Company was great to work with, the staff very knowledgable and helpful and to me "DeVilbiss" simply translates to "QUALITY" !!!

My O2 levels were dropping into the 70s while sleeping. I love the machine as I wake up with a clearer mind, and more energy. Glad my PCP ordered the sleep evaluation test! Thank You!

I am very pleased with this machine. I was renting one like it from a local firm & the rental saving will soon pay for this one I now own. From my research it seems that this is a very reliable & long life unit,also very quiet.

Exactly as ordered. They were easy to work with and I was able to get someone on the phone when I needed to do so.

For my Mom
I got this little beauty for my mother who needs it when she sleeps. She loves it because it's a lot smaller and quieter then the one she was renting. By buying this for her I saved her over 150$ a month. If your looking then look no further. Only thing that Stoped the 5 start was it didn't come with any new hoses.

Not very satisfied with this unit due to it only lasting 2 years. It was only used at night, and had only 1730 hours of time on it. Although it is still under warranty I have to pay the freight to ship it back. The unit did function very well up to the time it failed,but was a little noisy.
