What is C-Flex?
C-Flex is a pressure relief feature that makes breathing back against CPAP pressure easier to do by reducing the pressure at the beginning of exhalation and returning to therapeutic pressure just before inhalation. Independent studies conducted by leading universities indicate that patient comfort, and therefore, patient CPAP compliance, is higher with machines that use C-Flex. C-Flex is a technology invented by Respironics, is proprietary, and is not available on other brands of CPAP machines.

An example of a machine with C-Flex technology is the DreamStation CPAP Machine.

C-Flex Easy Breathing Technology Visual Graph C-Flex Easy Breathing Technology Visual Graph
What is the difference between Bi-Flex and C-flex?
C-Flex only works at the start of an exhale. Bi-Flex works during the transition from exhalation to inhalation, the transition from inhalation to exhalation and during exhalation.
Do all CPAPs use filters?
Yes, all CPAPs use at least one filter that is usually a type of foam material and washable. Some CPAPs offer finer filtration with the addition of a disposable paper filter.

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.
What does CPAP therapy do?
CPAP therapy provides a constant airflow which holds the airway open so that uninterrupted breathing is maintained during sleep. It is traditionally provided through a nasal mask that seals around the nose to maintain the pressure level.

What comes with my machine?
Machines come with a six foot hose, power cord, at least one filter, and manuals. Most manufacturers include a carrying case which is designed specifically for their equipment. CPAP, APAP, and BiPAP machines do not come with a delivery system or mask. CPAP masks must be purchased separately.

To see the list of what specifically comes with each machine, you can Browse for a machine. Then on the product page, click the "Specs" tab to see a full list of what comes with the machine.

Which CPAP masks work on which machines?

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.

Are prescriptions required for mask, machine, humidifier, and EPAP purchases?

Yes. Federal law requires we have a valid prescription on file before we ship your mask, machine, humidifier, or EPAP therapy, including Provent and Bongo RX. You will also need a prescription to purchase the Nightbalance POSA device.


We provide many easy ways to get your prescription:

  • We can request your prescription for you! When you checkout, just let us know you would like us to request your prescription, or you can log into your account to have us request your prescription.

  • Ask your doctor to fill out our prescription form. We have both a standard prescription form and an EPAP prescription form.


For more information on prescriptions, please see our Prescription Section of the Learning Center.

Respironics understands the business of Sleep Apnea

Verified purchase | Jan. 06, 2010 | Verified CPAP.com Customer
First off, let me say that my review of this product is tuned more toward the manufacturer than the product itself. I have only had my M-Series Plus C-Flex machine for a short period of time and am honestly still getting used to it. I will say that the reviews I read on this and other sites helped me make an informed decision and at this point in time - I am completely satisfied with my new CPAP machine. I purchased the bundled product with the heated humidifier - and as someone who refused to utilize a humidifier in the past, I must say I am more than pleasantly surprised by the performance of the humidifier as it works in tandem with the M-Series Plus. When I went in for my initial diagnostic sleep study - I physically removed the humidifier from the machine provided to me by the clinic as it made me feel as if I were drowning. That study was conducted 12 years ago and up until I purchased these products, my stance had not changed on the humidifier. I use the present humidifier on a very low setting which makes it more passive - and the heated, moist air that I am breathing in is such a huge improvement over what I had become use to. When I was initially diagnosed, I was prescribed a specific machine due to the fact that I traveled extensively - the machine was a Respironics Solo Plus LX. I was not given an option as my insurance company and Family Physician were working hand in hand on which machine they deemed most suitable. I trusted their judgment and am finding out now that their choice of the Respironics machine was truly a stroke of genius! The machine was heavy, bulky and a little bit noisy, but according to the reviews I have read on this and other sites - had more staying power than any other brand I have found on the market. My Solo Plus LX has over 35,000 hours of use on it and still to this day works as well as it did the day I purchased it back in 1998. I had to send it back to the factory for a repair one time about 7 years ago due to accidentally dropping it from a 5 foot high bunk - on to a very solid floor, but other than that it has required no maintenance. The only reason I chose to replace the machine was an as of yet unfounded paranoia about the machine breaking down at the worst possible moment. My wife and I discussed it and decided that having a "back up" machine was crucial - especially considering the fact that I had already received more than my money's worth out of the original Solo Plus LX. Imagine my surprise at how far the technology had come with regard to CPAP machines and the treatment of sleep apnea! My new M-Series Plus C-Flex CPAP machine seems almost like a work of science fiction to me. There are so many options for controlling the air flow to include adjustments for altitude and the C-Flex system itself. The auto on/off and mask alerts are both new to me as well! I purchased a Respironics battery pack to accompany my CPAP and so far have been completely satisfied with its performance and ability to hold a charge - as well as relatively fast recharging times. I made this purchase completely out of pocket and will say that I do not consider one penny to have been wasted. I am currently working in Iraq and had the machine shipped to me here - CPAP.com somehow managed to get the package shipped to me in less than half the time it typically takes to receive parcels from the United States. The overall cost of the CPAP-Humidifier bundle; Respironics battery pack; 12V power cord and ComfortGel mask - was actually $700 less than the cost of my original machine. Times have definitely changed with regard to the treatment of Sleep Apnea. In an attempt to summarize my opinion on the product being reviewed specifically I will state the following: This machine is extremely lightweight - comes in a perfectly useful travel case - operates quietly and has many options that increase your ability to find a comfortable manner of sleeping - with complete regard for your personal preferences. Based on my time invested studying the CPAP market and my recent purchase, I would recommend the M-Series Plus and Respironics in general to any consumer in need of a quality product that is durable and one that does not skimp on features that are crucial to a productive night's sleep.

An excellent machine

Verified purchase | Dec. 12, 2009 | Verified CPAP.com Customer
I purchased this as a secondary machine, as I split my week between two locations. The UK National Health Service provided me with a Respironics M Series Plus for home, and this unit is almost identical. The only difference I have found is that the menus in the cpap.com version use text, whilst the European version uses icons. The machine is quiet and compact, and the supplied travel case fits snuggly. The power supply is international, so all I need for UK use, is a replacement power cable, which is easily purchased from any electronics store. I have only ever had Respironics M Series machine, so I cannot compare them with other brands, but I think the C-Flex setting is very helpful. I'd recommend the optional heated humidifier as an essential accessory.

Machine works very well, somewhat louder than previous remstar machine, probably due to C-flex feature. Love the smaller size compared to Remstar. Just started using the machine but seem to feel much better in the morning with the C-flex function.
