Respironics has added their easy breathing CFLEX technology to the REMstar Auto. Now you can have both the comfort of auto-titrating pressure with the comfort of easy exhalation, all in one CPAP.
The Respironics REMstar Auto CPAP includes the following features:
- Automatically adjusts pressure based on air-flow limitations from snoring, hypopnea or apnea events.
- C-Flex technology offers a more comfortable way to deliver sleep therapy by giving pressure relief at exhalation. The amount the pressure is lowered is determined by one of three settings that you can adjust to your comfort.
- Encore Pro SmartCard compatibility records compliance and session data.
- Operates in Auto or CPAP mode.
- Automatic start and stop operation.
- Mask leak alert.
- Automatic altitude compensation adjustment.
- International power supply to operate on any AC current from 110 to 240 without adjustment to the machine. (An adapter may be needed to plug the CPAP into a wall outlet outside the US.)
- Direct DC operation without the need for a DC/AC inverter, just a cable and adapter which are sold separately.
- Two washable, reusable pollen filters are included, as well as one optional ultra-fine filter.
- Two year manufacturer warranty against defects.

Any mask will work with any machine, with one important exception. The ResMed AirMini is only compatible with certain ResMed CPAP masks. Compatible masks for the AirMini are as follows:
- ResMed AirFit™ N20 Nasal Mask
- ResMed AirFit™ F20 Full Face
- ResMed AirTouch™ F20 Full Face
- ResMed AirFit™ P10 Nasal Pillow
When considering another CPAP, APAP or BiPAP machine from ResMed or any other manufacturer, mask compatibility extends to all brands. The AirMini uses non-standard tubing to connect the machine to the mask, and is the primary reason why other masks won't work with the AirMini. Despite this issue, many of our customers consider the AirMini to be an excellent machine.

Here are some other suggested actions to care for your machine:
- Keep the area around your machine clean by removing any dust from the area to improve the air quality delivered to your machine and to you.
- Keep the air intake of the machine unblocked. Curtains, bedding, and papers can easily block the air intake of your machine, reducing the airflow.
- If a humidifier is used with your therapy, do not pick up the machine with the humidifier attached. With most machines it is easy to spill water from the humidifier chamber into the machine causing damage. Manufacturer warranties are voided by water damage to the machine. To avoid this, remove the chamber from the humidifier and then remove the humidifier from the machine rather than transporting them together.
- If a humidifier is used, empty the water from the chamber every morning. Accidents happen. If a family pet or family member moves the machine and humidifier with water in the chamber it is more likely that water could be spilled into your machine. Water damage to a machine voids the manufacturer warranty.
Cleaning and changing filters is the only maintenance required for a CPAP machine.
The filters are located at the back of the machine at the air intake.

Very nice machine, more deluxe than my last machine, I like the auto adjust, would like the machine to come... on with greater ease without having to push the start button.... more...
Outstanding product, was to be with me in my BIG-RIG, but the wife says that it's so quite, it's like... white noise. Guess it stays at home and the older version go in the truck. more...
Great machine - very quiet.
no noise!!!! wow
Great service!
Alot better then my old machine too much pressure but have to get it adjusted I like it but should... have paid more for the bipap or bi level those are nice machines more...
Respironics, in my mind after 15 years of CPAP therapy, is the gold standard in CPAP machines. The REMstar... Auto C-Flex CPAP maintains that standard. It is a good, solid machine that has performed flawlessly for me so far. It is not one of the newer, smaller devices that I have had my eye on for travel, but rather a black box with enough heft to it that it will not slide around on the night stand as the hose moves around. I have a small Goodnight travel model but I suspect I will be using that as my back up and my REMstar as my handcarry model. While it is a wee bit larger, I do not have to worry about the bulky, external power pack the smaller devices fail to clearly tell you about. I have developed a system where my CPAP stays in a drawer at home, along with the hose and mask. When I need it I simply pull out the hose and head off to sleep. The auto on feature makes things easier along this line. It would be nice if Respironics could come up with a prettier color than the basic industrial black, but that is a small price to pay for a hardy, quality machine. more...
I purchased this machine to replace a PB 420E. I chose this style of the Remstar because I already... have a Remstar Pro CPAP. I have used the auto now for approximately 2 weeks and I am sleeping better than with the 420E. Data pulled from the data card with the software shows a better AHI index than with the 420E. Overall, the machine has been great. It is quiet and performs like I expect it should. Pros: It's easier to take just the data card to the reader and not have to pull the entire machine (as with the 420E). There is only 1 power cord for both the humidifier and machine. The Humidifier is easy to fill with the enclosed funnel. This machine takes standard hoses (no sense line required). Humidifier parts are compatable with the Remstar Pro CPAP. Cons: None so far Good and solid. I recommend it. more...
seems to work fine
I've been using my old CPAP every night for almost 4 years. My last checkup was recent & the Doctor... gave me a new prescription for a new CPAP with new C-Flex features. He stated that "with the new Auto C-flex features, the machine will sence & auto adjust my needs." At first I wondered if I really needed it,& I thought about it for a while. I thought it would be a good idea to have a spare machine around so I got the new one. I must say I'm impressed with the way the new one works. There is a nice, comfortable feeling with the way that I'm breathing now vs the older model. My breathing feels more natural with this new model with the C-Flex features then ever before. I like it alot, & I'm sleeping well. I would recommend getting a new machine with the C-Flex features to anyone. Alot of people I know, friends & family members are having a hard time getting used to the mask. I feel I've learned something. The idea is to keep the straps as loose as possible, as long as it doesn't leak. If the mask is too tight on your face, you may never get used to it. I know buying a new CPAP with the new features is not cheap but, I feel the expence was worth it. Just knowing that the machine will auto adjust to my needs while I'm sleeping, is a comfort I find valuable. more...
I have purchased two machines from cpap.com, the respironics m auto a-flex and the older remstar auto c-flex. The remstar... is MUCH quieter than the m auto a-flex. It seems to also be a little better made and I suspect it will hold up better over the long haul. A-flex is a little more comfortable than C-flex, but I may just be better acclimated to the a-flex as a-flex was the first modality I started with. I go back and forth between the two machines. If you want a quiet machine, I think you'll be happy with the remstar c-flex. Thanks. more...
after 5 years on a regular c-pap, I was having difficulty sleeping. A sleep study was suggested, and I was... given this machine to use for a 5 night study. I couldn't believe the difference. My insurance wouldn't cover this one, too soon, so I purchased online here. This is the most comfortable unit I have ever used. Quiet, you don't realize it's even on. Very comfortable. I think this is as good as it gets. more...
