It just works!

Brett S. – July 31, 2007

"I have used my Sleepstyle 608 now for over a week, and have been extremely happy with the results.

My chief problem in using a CPAP machine has been humidity levels(too high or too low), and this machine has taken that completely away.

I struggled with CPAP because of low humidity, but adding an external humidifier only added to the problems. If I guessed the humidity levels wrong, I either woke up dried out like a desert, or awoke in the middle of the night with water gurgling in the tubes. I could never get the levels right, and so I gave up on CPAP.
With the 608 I am a believer again. I have have none of the issues that kept me from doing this important therapy.

This unit automatically adjusts to the ambient humidity according to a "comfort level" you can choose, and the heated air hose stops any condensation problems - I no longer have to guess what settings to use, and the machine has eliminated the frustrations of guessing wrong.

One thing I did find is that the breathing tube is not the proper size to fit the Innomed Nasal-Aire II mask. The fitting on the supplied heated hose is slightly too large. I had to wrap some electrical tape around the mask's swivel end to get them to seal, but it's a small issue.

Other positives include the ramp up time - I have not had any issues falling asleep beyond the first night (I had to get used to a mask/chin strap/machine again), and the water chamber is easy to fill (and comes with a spare). Also, the 608 is very very quiet - I don't think I have heard it once since I bought it.

Improvements I would suggest - Exhalation pressure relief, leak/mask off alarm, standardized fitting sizes.

All in all, I am very happy I bought this machine so that I could return to my CPAP therapy and not have to deal with the hassles of my old machine/humidifier.

If you or someone you know struggles with humidity levels with their CPAP machine, I would highly recommend the Sleepstyle 608."

"I really like this CPAP. It is easy to use, relatively easy to travel with. The fact that it is a simple cord (the voltage regulator is inside the CPAP) really helps when I go to pack it up. The heated hose is nice but note if it gets under a pillow and can get really warm to the touch. The only thing I wish is that it would come on automatically when I put on my mask like my resumed did."

"Very pleased. I hope to say the same in the winter. With my other machine I had a LOT of trouble with rain to the point that I almost gave up. The machine makes a big difference in the quality of sleep I receive."
