The M Series Pro 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, and powerful clinical data features, onboard.
The M Series Pro with C-Flex offers optional integrated humidification, Encore Pro SmartCard capability for advanced clinical reporting, lighted controls, an easy-to-read display and the comfort of C-Flex.
The M Series Pro sports a small, sleek device and case, a less obtrusive profile with tubing connected in the back and a "hidden" water chamber.
The Pro offers lighted primary touch controls for power, ramp, and C-Flex as well as a LCD display and controls for easy set up.
The humidifier controls have been simplified and now include an easy turn humidification dial. A water chamber that is easy to remove, fill and replace
delivers continuous humidification throughout the night.
The M Series Pro is convenient for travel with or without the integrated humidifier. The standard travel carry case has been updated with a new sleeker look.

Power Options
Universal Power
The M Series Pro operates automatically between 110v – 240v AC. When traveling either inside or outside the USA, there are no switches to switch or fuses to change. The machine will automatically sense what voltage is needed and set itself to run on the power needed.
The user will need to adapt the plug that goes into the wall to fit the style of outlet socket that is being used. This is simply done with a Power Adapter Plug kit. This is the same type of plug adapter that would be used with a hair dryer or an electric shaver.
The M Series Pro comes equipped with a DC plug on the back of the unit. This allows the user to connect the CPAP to an external DC battery source.
Using a Respironics, 12volt DC Power Cord the M Series Remstar Plus can be powered by plugging into a cigarette lighter plug. This is ideal for traveling by car, boat, or recreational vehicle that is equipped with a cigarette lighter plug.
It is recommended that you use a 100 amp hour, 12v DC deep cycle marine battery for operating you CPAP machine when not connected to 110v AC /230v AC.
There are two cables needed to configure the M Series Plus with a Marine Deep Cycle Battery. They fit together to make a connection from the back of the M Series Remstar Plus to the battery clip terminals on the marine battery.
Here are the links to the cables needed to hook up to a marine style battery. Both cables are needed.
The Respironics Battery Pack has been a long standing favorite of our customer’s. It weighs in at 13lbs and can be carried easily with its shoulder strap.
This battery pack will give roughly 26 hours of use, depending on the cpap pressure setting. (Results may vary.)

REM star PRO series M

(5 out of 5) by David B, Dudley, MA
"The REMstar Pro series M CPAP machine works very well.The auto start feature works well unlike my previous
machine. The smaller size is great for placement on a night stand and the adjustable humidifier is much nicer
than having all or nothing for a choice. My only issue is that the blue lights for the control buttons give off more light at night than I care for. All things said I'm very happy with my purchase."

"I had a resmed compact S8, cpap before. It would always be hard for me to breath out because of the constant air always comming out. Now that i have the "M series Pro C-Flex" unit i don't have to worry any more about it being hard to breath out anymore. It came set up for me by the "Cpap.com" people so all i had to do was to hook up my mask and i was in busines.The machine is very quiet not noisey at all. "Great Product"!!!"

"My Old CFLEX Pro Finally Died After 8 Years Of Service After 2 Weeks Of Reading Reviews On CPAP.COM I finally Decided On The M Series CFLEX Machine. My First Impression Of This Machine Was How Compact It Was Compared With My Old Machine A lot Simpler To Alter Settings Such As Humidifier Temperature,I Also Like The Information Display Again A Lot Simpler In It's Design And Simplicity Of Use. A Couple Of Things That I Was Not Happy About Was I Thought The M SERIES Was A Lot Noiser Than My Old Machine,My First Night Of Use I Woke Up 3 Times And in The Mourning Had A Really Bad Headache Perhaps The Whisper Box Could Have Been Suggested. The Humidifier Is a Lot Smaller Than My Previous One But Is Adaquate For A Couple Of Nights Usage.Overall I Am Very Satisfied With My New CFLEX And Feel That The Reviews Helped Me Make The Right Choice.Pricing Was A Great Deal Cheaper Than Australia And The Service Was So Much Better Than Here"
