M Series Auto CPAP Machine with C-Flex
The M Series Auto is a small and feature packed CPAP that looks more like a stylish clock radio than a CPAP.
It easily packs away in your carry on luggage, and has an incredible number of high-tech features, including the patented C-Flex comfort feature, self-adjusting pressure, and powerful clinical data features, on-board.
Manufactured by Philips Respironics.

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.
All CPAP masks work with all machines.
We provide our customers with many tools to make informed decisions about their machine purchases. Options include:
We work very hard to provide many different ways for our customers to compare products. Here are the machine product guides we have created and maintain:
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 / BiPAP / APAP 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.
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. The image below shows the black foam filter at the back of the Everest 3 CPAP Machine.
Yes. Federal law requires we have a valid prescription on file before we ship your mask, machine and/or humidifier.
We provide many easy ways to get your prescription:
Exhalation relief is a comfort feature offered by two manufactures which reduces the air flow at the time of exhalation making the breathing process more natural.
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.

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.
The only care a CPAP or BiPAP machine requires is to clean or change the filters at the air intake. This keeps the internal parts from accumulating dust. Fine paper filters should be changed out every 30 days, or when they appear soiled. Foam washable filters should be rinsed with clear running water once a week, allowed to air dry, and reinserted.
There are some other suggested actions to care for your machine:
Some CPAP users find it more pleasant to breathe with an APAP than with CPAP. The pressure delivered by an APAP machine automatically changes as needed to deliver the minimal pressure required to maintain the airway. The pressure delivered by a CPAP machine is set to a single pressure, the highest necessary to keep the airway open as determined during the sleep study. This is the case even when the higher pressure is needed only a fraction of the time.
The ramp button on a machine is a feature that allows for a gradual pressure build-up to your prescribed pressure. The feature is enjoyed by those with high pressures because they ease up to their pressure.
CPAP machines which record full data (such as AHI and leak info):
First you need to determine if your machine is configured to operate on DC power and has a DC power outlet. If your machine does have a DC power outlet and you want to run your marine battery, then you will need the correct DC cable for your machine and an adapter cable that fits over the cigarette lighter plug and ends in alligator clips.
CPAP.com sells complete battery kits with everything you need for your machine including the right cables for your machine and the battery. You can find the right battery kit for your machine here.
If your machine does not have a DC power outlet, then you will also need an inverter to be able to run your machine on battery power.
If you have questions about the specific power needs of your machine, review the "Power" tab on your machine's product page, or give us a call at 1-800-356-5221.
CPAP stands for Continuous Positive Airway Pressure. CPAP therapy is the most recommended and the most effective treatment for obstructive sleep apnea.
A CPAP machine provides air at a constant prescribed pressure through a tube, using a CPAP mask to deliver the air pressure to the person with obstructive sleep apnea. CPAP therapy provides a constant airflow which maintains the airway open so that uninterrupted breathing is maintained during sleep. This eliminates sleep apnea events and allows the patient to get a restful sleep.
The pressure of the air is determined during your sleep study and your doctor will prescribe you a CPAP machine at that pressure.
CPAP therapy is traditionally provided through a nasal mask that seals around the nose. However, more innovative and comfortable options are available and advances in the delivery of CPAP therapy are continually occurring.
For instance: CPAPs which offer FLEX or EPR technology provide exhalation relief, a slight drop in pressure at the time of exhalation. APAP, BiPAP and BiLevel machines offer various levels of pressure throughout the night.
When a physician orders a pressure change, or a patient moves to an area with a very different altitude and does not have an altitude compensating machine, there are a number of ways to ensure you are receiving CPAP therapy at the correct pressure.
Sleep laboratories and sleep disorder centers may be willing to make this pressure change. Just call a big local hospital or ask you physician for sleep lab phone numbers. Be sure to take your prescription.
A second way is to do it yourself. We sell manometers that are very portable, accurate, and simple to use. All the machines we sell come with instructions on how to set pressure to physician orders. Most patients have little trouble doing this themselves. If you need help we can talk you through the procedure.

A third option is to ship the machine to us with the new prescription. We will set it and ship it back.
It is the law and good common sense to run all sleep disorder devices at the prescribed pressure. If you think your prescribed pressure is wrong, talk to your physician.
There are a lot of back up battery choices out there that can give you peace of mind in case of a power outage. The Transcend Travel CPAP Machine has Battery Options available for that can set up as a fail-over, back up battery. Review the "Power" Tab on the machine page.
CPAP.com sells battery packs to accompany your machine if an integrated battery is not available. Visit CPAPtalk for more advice specific to your needs, or view this past thread on the topic here.
