M Series Auto CPAP Machine with C-Flex

The Good: 1 - This is possibly the best looking CPAP of all time. It looks much better on the nightstand than the others I've had (and I've had a few). 2 - It's a decent size for travel. 3 - The software isn't very sophisticated, but it gets the job done. 4 - It's fairly quiet. 5 - The humidifier is easy to fill. 6 - It seems to be well built. The Bad: 1 - The blue lights on the buttons are crazy bright. I had to use electrical tape to cover them up. 2 - I don't really like the feel of C-FLEX, so I turned it off. 3 - The humidifier doesn't have enough capacity and it doesn't run hot enough even on the top setting to use all of the capacity in an evening, which leaves me feeling dried out, particularly in the winter. I still haven't found an integrated humidifier in any CPAP as good as the HC150. 4 - I wish the display would provide data from the night before instead of an average over the last week. 5- The 2 cables coming out of the big power brick are a pain. I am now using a new Respironics PR One Auto as my main CPAP and I actually think it's a step back from this model in most ways (other than the fact that it can supposedly detect and treat RERAs).

good product , good service

Just got my new M series Auto C-Pap with CFlex. Have had a Respronics machine for 9 years, decided I needed an upgrade with a better humidifier that was heated, after my recent testing, with adding more air flow. So far I'm satisfied with my new machine and it's definatly quieter than my old one.

M Series Auto CPAP Machine with C-Flex is very silent, comfortable and user friendly. I highly recommend this machine to all CPAP users.

I have used this machine and it's prior model for several years with no problems. I purchased the smaller updated unit both because it was lighter (for traveling) and because I felt I needed a backup in case the other needed to be repaired (assuming it can be, and that Respironica will still be making the parts). I use my older unit at home and take the newer unit when traveling. I choose the Auto C-FLEX model with Humidifier because experience has taught me that I need these features to be comfortable. Auto C-FLEX (with ramping) is incredibly comfortable to use, providing effortless breathing, and changed my life from the very first night I began to use it. I had apnia so bad that I simply counld not stay awake during the day, and started to nod after only an hour behind toe wheel of a car. I snored so loudly that my wife started making me sleep in another room. Life was not good. By the way, I choose the nose gear (Puritan Bennet Breeze SleepGear with Large (Green) Nasal pillows. I have found this system the most comfortable for me, allowing almost unlimited movement at night on both sides, on my back (for the firse time in years), and on my stomach (head to the side of course). The standard hose has proven to be adaquate. The filters are great, especially the micro dust and pollen filter (clean air all the time. Breathing moist air, by the way has a surprising cooling effect on vary hot nights. I have found it valuable to carry an extension cord and one extra milti outlet plug when traveling to allow machine electrical connection to plugs far away from the bed. One final comment. I have found the DC connection capability of the machine to be invaluable when camping. I purchased the DC adaptor, and attached the machine to a Marine Battery rated at 150 amp hours. The machine consumes an average of 3 amp hours (18 amp hours consumed if you sleep a 6 hour night). I re-charge the battery with an inexpensive solar unit the size of a sun visoor and have kept the system going for 2 weeks when fishing. I carry distilled water (20 oz in a Sams Club bottle) and have not run out yet durig a trip - water evaporated slowly in the humidifier. Good product, easy breathing in and out, minimum discomfort. Thanks for the high quality engineering - that such a simple thing could make such a difference in my life at the price it is offered.

Small compact size,easy to carry able to used with most Volatage I am happy with this machine.

Over the last 5 years I have used two CPAP machines (a Fisher-Paykel HC221 w/ heated reservoir, and a Respironics RemStar M-Series also w/ heated reservoir). Although both were billed as "top of the line", neither were really satisfactory to use. Both had similar problems. When the machines are set to the pressure recommended from the sleep study they were miserable to use. There would be inevitable leakage around the mask, or air would be forced out through my mouth when I'd fallen asleep - painfully desicating it, or both (depending on the type of mask I used - I've got 3 different kinds). Recently my doctor tested me at home on the RemStar M Series <i>AUTO</i> CPAP (no reservoir) to see if a better pressure could be found. Wow!!! What an amazing difference! As far as I'm concerned the tests were irrelevant. The machine is the answer. This machine constantly changes the pressure with each breath, so there is never too much air being blown into the mask. Now, I get all the air I want/need without the sense of excess pressure. Gone are the incessant mask leakages, and awakening with "Death Valley mouth". As far as I'm concerned auto-titrating machines are the ONLY way to go. Does it cost more? Yes. Is it worth it? You betcha!

The auto and C-flex features make the less than desirable need to use a CPAP device more comfortable than I expected. The first night the auto feature of the machine adjusted the setting to a higher setting than had been determined at hospital during the CPAP sleep study. The ability of this machine to optimize the pressure is very convenient compared to a friend of mine who has a fixed pressure on their machine and has to have another sleep study done to determine the new setting.

I used the product first time last night with humidifyer attchment. Really had a good nights sleep. disapointed with the noise level, it is louder or equal to my respironic 6 year old model. Complaint from my wife who used ear plugs.

This machine is very quiet. As soon as you put the mask on, it self-activates. I have never used a CPAP machine before, but this one seems very intuitive and consistent. The design is sleek and black. It hardly looks like a medical device on my nightstand. The additional card and reader have ample amount of data that my doctor can use . My husband is delighted that he is getting a good night's rest, because I am no longer struggling with snoring and breathing.

This is my first cpap machine and I'm very happy with it. It's quiet and easy to operate. I like the smart card, I can just pull it out and take it with me to my appt. for the Dr. to read. I'd recommend this machine to anyone needing an auto cpap. I appreciate the great service from cpap.com also.

I love the lower pressure during my awake states. My partner enjoys the lower air flow (and hence, noise levels) as a result of the lower pressure too. Previous machine: Remstar Pro with c-flex.
