Heat moisture exchange unit
Tried this out in place of water humidifier and could not tell the difference. Makes sense to take this small tube insert vice the large humidifier tray. By Tom B, Hampton NH
Works for me
These filters actually work as a humidifier replacement. Duration wise, they can easily last one week. The only downside is that they are a little bulky and make the tubing heavier By Giorgio R, Chicago

Works great with transcend no dry mouth By Harry M, Verona kentucky
Really wanted it to work
I travel a couple of times a year for long periods. Lugging my CPAP and humidifier around isn't fun. I was really hoping this would work so that I could lighten my load by just carrying my M-series machine. But, alas, unfortunately it just dries me out too much without the humidifier. In checking the machine data, there is an indication that I had less large leaks using this instead of the usual set up somehow. Apnea score about the same. But my dried out tongue and throat tell the story. So, as much as I had hoped this would work for me, it really didn't. By Glenn, Arlington, VA
The trick is to keep it close to your mask
This humidifier works to minimize loss of moisture that you breathe out from the mask, and is thus retained for you to re-breathe. It still allows air to run through it.
When we breathe out, a very large amount of natural moisture escapes with each exhalation. In order to take advantage of this, the humidifier/blue sponge should be as close to your mask as possible, which is not always possible with certain types of masks, like nasal pillow designs.
If you want to use a nasal pillow design mask with a heat exchanger humidifier, it is still possible to put a little "cylinder" of blue sponge material at the entry spot where the hose goes into the mask. But this particular humidifier won't allow you to do that.
You CAN do it with the one that is offered by CPapxchange made for the Transcend dehumidifier, which is not enclosed in a plastic fitting.
It is vitally important NEVER to cover the exhalation outlet parts of your mask with any materials, including these filters. This means installing the blue filter OUTSIDE of your mask, usually where the hose line connects to it. The exhalation portion of each mask is scientifically designed by the manufacturer to allow carbon dioxide to exit from your mask. All masks are very carefully tested to accomplish that.
However, after experimentation, I found this works quite well. Remember to discard the blue sponge material after 7 days. They are never designed for longer use.

What they said
1) Yes, it is not as nice as heated humidification. However, 2) It works great when indoor humidity is not too low (e.g., winter -- but can't test for Winter for another 4 months). 3) I agree that the size and weight savings even for two or three weeks travel are amazing. 4) I agree that not having to get water, clean humidifier tray, or plug in a humidifier make business trips easier. Am studying use with 3 masks and comparing data to regular humidification. Will post results if different. By Harlan, Vermont
Does the job claimed - okay for travel on the go. Nothing as good as a real humidifier of course. By Sue, NV
nice unit.... so far... By ANDREW B, union city,mich
Works With My Restar
I've been using the inline humidifier filter with my Remstar CPAP for business trips. It's much better than bringing the whole humidifier and having to clean that every morning before leaving. So far I've been getting several days with each filter, but I haven't tried to stretch it to a week yet. I still use my heated humidifier at home, but these are really useful for reducing travel bulk. By Tony R, Rochester
