M Series Pro CPAP Machine Overview
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, on board.
This model is no longer available. For a suitable alternative, we recommend the DreamStation 2 Machine. The DreamStation CPAP is a quiet, sleek, and modern CPAP device. The DreamStation family of machines are only 25.8 decibels and are considered among the quietest on the market.
Looking for an auto-adjusting machine? Consider the DreamStation 2 Auto with Heated Humidifier, which combines automatic pressure adjustments with the comfort of humidification all for one low price.

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 additional compartments and sleek design.

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. World Traveler Power Adapter Plugs.

This machine come 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. The IntelliPAP can be powered by plugging the 12volt DC Power Cord into a cigarette lighter plug. This is ideal for traveling by car, boat, or recreational vehicle that is equipped with a cigarette lighter plug.

The 2.5 lb CPAP.com Battery Pack is surprisingly small and lightweight. The lithium ion battery can be recharged at any discharge level without losing charge time due to battery memory loss.

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.

C-Flex Easy Breathing Technology Visual Graph
This machine replaces an older model (8yrs) and has shown to be a far superior product. I like the... fact that it is in two pieces rather than one. This means that when I travel I can carry the lighter part with me in my carry on and pack the heavier power supply in the suit case. Also, the C-Flex feature makes this machine usuable all night (8hr) versus just a few hours a night without this feature. Without this feature the tendency is to not wear the mask all night. However, this C-Flex feature makes exhaling into the CPAP very easy and relaxing which allows me to wear it all night - and sleep! It is also proving to be a very quiet machine. more...
The machine is nice and compact. Although quiet when you just plug the hole, it makes more noise when... you actually use it with a humidifier - but not too bad. The unit is easy to operate and does the job with ease. The price is great from CPAP.com. more...
Easy to set up and use. Push one button if you want to turn on and off. Fairly small... footprint. Hose exits rear of unit which is nice. This is the 4th M Series Pro C-Flex I have owned. The first one lasted 18 months. Then in lieu of a new one under warranty the supplier (not CPAP.COM) sent me refurbished units. The first refurbished unit failed in 2 months and the second refurbished unit failed immediately. The supplier then sent a different brand but it didn't work here in the Colorado winter because the humidifier produces a warm mist that condenses too easily in the tubing when cold. That's why I went back to this unit. It produces more humidity at a lower temperature. I hope that this machine lasts. more...
I purchased this machine with humidifier. I'm replacing a M series plus machine with this model. This machine is... software ready where my other model was not. I like the size and quietness of machine. Very easy to use this machine. I'm happy with purchase. more...
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. more...
Excellent Cust Svc assistance and very quick delivery on the product. Great job by the CPAP.com team
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"!!! more...
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 more...
This machine produces a very noisy whine which varies in pitch and volume with each inhale and exhale. I f... nd it annoying; my wife has difficulty sleeping due to the noise. more...
My old Remstar Auto had a problem and was sent to be fixed so I needed another unit in the... meantime. My DME loaned me the M Series Pro and I really liked it. The price on CPAP.COM was wonderful, and my DME could not believe the price I paid for the unit. The only issue I have are the blue lights that cannot be dimmed. So a washcloth is laid over the top of the unit at night. No big deal. The machine is excellent and with the smart card and reader my therapy continues to be monitored. Got my Remstar auto back from Respironics fixed with some new additions and I am placing that unit as my backup. Great friendly service by the folks at CPAP.com. A pleasure to do business with them. more...
I love it! I am very pleased with the quality of this machine. It is super quiet, which... my wife loves. It is very compact and light weight, making it easy to take along on trips/vacations. Nice case holds everything. more...
The unit is small enough for easy travel, easy to set up and use, and operates quietly. Internal controls do... a good job of regulating the air with a minimum of discomfort during use. more...
