M Series Pro CPAP Machine

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.

Outstanding machine

Verified purchase | Feb. 25, 2010 | Verified CPAP.com Customer
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.

M Series Pro C-Flex CPAP Machine

Verified purchase | Jan. 25, 2010 | Verified CPAP.com Customer
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.

Easy to Use

Verified purchase | Jan. 17, 2010 | Verified CPAP.com Customer
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.

A User Friendly Machine

Verified purchase | Dec. 19, 2009 | Verified CPAP.com Customer
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.

REM star PRO series M

Verified purchase | Sep. 26, 2009 | Verified CPAP.com Customer
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.
