I, like you, cannot sleep without humidity. I use the Z1 HME 4 out of 7 nights most weeks. It is an adequate compromise for travel use. It certainly isn't as comfortable as heated water humidification but you won't wake up parched either....at least that has been my experience.

You can purchase one, turn off the heat and put a regular hose on my System One so that you can use the HME and try it at home for a night or a week to see if it will work for you. Actually, I dont think you need to change the hose, just turn off the heat and humidity.

I find that the bipap is very noisy, but have adjusted to the noise level- I have been getting frustrated with traveling with my bipap (without my humidifier to make it more lightweight) and was wondering if I would be more comfortable with the Z1 auto (is the humidifier built in?)

Thanks
I have two opinions that I hope you will find useful:

First bipap noise: I have one; it's a PR760. I took Julie's advice and put it below the bed, beyond my knees, sitting on a mouse pad. I can't hear anything anymore.

Second: If you take a Z1 with all of its gear; hose, mask, etc... and put it in a box; then take the PR760, remove the humidifier, put it in a box with all its gear; you end up with just about the same size box. The Z1 has not humidifier!

From a portability perspective, the Z1 and the PR 760 don't really compare. As I talk about in an earlier post, there are different types of travel and those different types call for varying degrees of portability. It's true you could probably stuff both systems (without humidifiers) in similar sized bags but the 760 is nowhere are portable as the Z1 (and I assume Transcend) for the Hiker, Camper, Biker, Carry-on Flier, etc. If you're driving from your house to a hotel you can, and probably should take your complete humidified system and call it portable.

I'm not going to go into all the specs but here's an important one.

Z1 Auto and adapter - 20.9 oz

760 and 80w adapter - 67.04oz

well if you're going on battery power, you wouldn't put a PRS1 X60 on its AC adapter. That thing is crazy heavy and big. I have carried the PR APAP and humidifier on the bike and done fine staying in hotels. I have a FJR touring bike and plenty of space for luggage. I't like to get into a battery setup so I can cut costs and do some camping. At this point I think the Poweradd might be the way to go, but I have a Shorai LiFePO4 battery that might work...need to do some trial and error.

For use of the Z1, the Fischer & Paykal HC150 humidifier looks like a good accessory for a Z1. You could run it as passive on battery and cut the noise, or if you're in a hotel, use it on power

Sleeprider, My post was for electric power. Battery power is a different animal.

I actually have a F&P 150 and took it for a while in my roll aboard but it is just too big. I then tried it just as a non heated humidifier and I didn't find that it worked any better than the HME so I use HME's which I can shove into one of my shoes in the roller.

The F&P 150 does work very well though for anyone who needs one and I think I only paid $79 for it.

I agree there is a difference in weight. Hiking or biking is where there is a big difference. Also if you need battery power then the Z1 has the advantage. In a plane, on a long flight the Z1 should be better because you can sleep with it (battery power). Otherwise the Z1 is a waste. I have read a few of the post about the Z1. I was going to buy it. I don't think this is a product I could sleep with. But you should keep posting your opinions about the Z1 because your views have prevented me from wasting my money on it!!!!!!!!!!!!!

Great! Now I can sleep better at night
I did not intend my post to offend you; hope it did not. It's just that you have been useful and I wish to thank you for your many comments and I hope you will continue. I suspect many have benefited from your insights! Thanks!

bill-e, can you elaborate on "the noise level will be resolved soon"?

Also, do you happen to know whether the multi-night battery on the Transcend will work with the Z1 (I'm thinking it might)?

Background: like you, I travel almost weekly, 2-4 nights at a time in my case. I use a PR System One at home (which I'm very happy with) and the Transcend II Ultra-Light when I travel (which I'm resigned to but am not completely happy with). I've been using the Transcend on this schedule for almost three years, so I have plenty of experience with it.

In my case, I find the Transcend to be considerably more noisy, and considerably less comfortable, than the PRS1. The noise I just deal with (unless my wife is with me, in which case I bring the PRS1), the breathing discomfort is getting to be more of an issue.

Part of the problem may be that the Transcend II doesn't have exhalation relief, which I use at home. I'm debating between the Z1 Auto (LOVE the small size, as I almost exclusively travel with a roll aboard and and my CPAP goes in the roll aboard), Transcend Auto (small enough, less expensive and will work with my multi night battery for rare overseas trips and power outages), or just buying a second PRS1 or Devilbiss IntelliPAP for travel (I've learned the hard way that I need a dedicated CPAP for travel or I WILL forget something at home). I'm not optimistic that the darth vader noise level of the Transcend will change any with the Auto version; while the size and weight difference is minimal, the Z1's flat design (I wouldn't use the powershell) seems like it will pack easier.

Levman,

I don't know anything about the Transend battery but I can tell you that the Z1 will work off a 12v battery source.

The Z1 Auto is in my opinion more comfortable to use than the original Z1. I use it on APAP-3 exhale relief setting. I assume that like the Transend, you have to use the Z1 for a little bit to get used to the different way the pressure is generated, that is small fast blower as opposed to a larger slower one. Once you sleep with it a few nights it is comfortable. I feel that the Z1 algorithm also takes a while to "learn" your pattern though I've never had that confirmed by HDM.

Since you use your Transend often like I do and since you're home machine is the same one I use, I have little doubt that you would also reach the same conclusion with the Z1 Auto as I have, and that is that with the noise fix (when it is released), the Z1 Auto is just about as comfortable as the PRS1....not taking into account the lack of Humidification.

As to your comment about the Transend's noise changing with the auto version, The noise from the Z1 and Z1 Auto are identical...if that's any help.

I keep my Z1 in my backpack in a form-fitting case from an old digital camera. I keep the rest of my supplies in my roller. Since I travel a lot on RJ's my roller often goes under so I like to have the Z1 in my backpack.

Levman,

Bill-e has mentioned that HDM has some sort of solution in the works for the noise issue on the Z1 - I don't know anything about that so I'll let him give us an answer on that issue.

I started with the small Tavel machines with the first Transcend straight cpap model and I managed to do very well with it over time. Admittedly it was a bit of a struggle first few nights, but I soon adapted to it well. I do wear the little yellow 3M ear plugs at night, but with both these little machines a lot of the noise isn't coming through my ears, but more of a transmitted noise from hose and mask through to your skull. I notice that when I take the ear plugs out there is not much difference in the Darth Vader noise. After the first two nights with the Transcend I was able to sleep regardless of the noise.

I did upgrade to the Auto model of the Transcend and found it pretty nice to breath on, but every bit as noisy as the straight cpap model, but not so bad that I couldn't sleep, you get used to it after awhile. But when I tried the Z1 cpap version I found the Darth Vader noise issue to be much more intrusive than the Transcend. Also took a little more effort to get used to breathing on the Z1.....it was a real struggle at first, but now after forcing myself to get used to it I've gotten to the point that the breathing issue is ok on the Z1 using their latest Z Breathe cpap 3 setting and I can finally get to sleep with it as far as breathing goes. But at the present time the Darth Vader noise issue is keeping me from getting a restful sleep no matter what I do with larger hose and using the HME.

So just posting my opinion that the Darth Vader noise issue is more pronounced on the Z1 than it is on the Transcend and its a real problem for a machine that is meant for SLEEP therapy, so I sure hope Bill-e is correct that HDM a has some sort of fix coming out soon!

As far as battery power the Transcend runs on 19.2 volts and the Z1 voltage is 15 volts, but both have adapters available so they can operate off a 12 volt source......look on cpap.com at both machines and then click on replacement parts for each and you'll find the 12 volt adapters for both.

If you are referring to the Transcend branded battery I seriously doubt that it would work for the Z1.....the plug for the machine end is different and the voltage is too high. I do use the c-100 battery for both machines with the appropriate adapters for each.

Hello. This is my first post. I've been using my System One for over three years, and it's fine. I'm traveling much more now and am old and have a bad shoulder and back, so weight and portability are important to me. Have been considering a purchase of either a Transcend or a Z1.

My question to the travelers with a Transcend is, do you use the humidifier when you travel? It seems that adding the humidifier will make the Transcend almost as big and bulky as lugging along my System One.

I went two nights not using the System One humidifier this week and while I did fine I was a little parched in the morning. It's been very cold so the heat is on and the air is dry at home, but I did ok.

One other observation - I was recently in London and other cities in the UK and could not find distilled water anywhere!

TaxBabe, I do not use a humidifier when I travel with my Transcend (or on the rare occasions when I travel with my System One). As I travel frequently, I've opted for convenience over comfort. I like a cool room when I sleep so I often leave the heat off in my hotel room, which probably helps.

Have you considered traveling with the System One but without the humidifier?

As others have pointed out, these small CPAPs take some getting used to. In my case, at least with the Transcend II (no exhale relief), after three years of regular use I find it to be tolerable but a definite trade off of comfort for convenience.

No, you would not want to take along the humidifier for the Transcend, it would negate the bennefit of the small, light weight travel machine as you have pointed out. I find that when I travel to places near sea level that have a relatively humid climate it is not a big issue to not have a humidifier, but of course, on the flip side if you are traveling to a dry climate then it becomes more of a problem. I think Transcend came up with the humidifier option for people that wanted to use the small machine at home as their primary machine when not traveling.

As an alternative, and a bit of a compromise, travelers with these small machines have been relying on an HME device which for all practical purposes is a fiber ball stuffed in a plastic tube that fits between your mask and hose. It's supposed to capture some of the moisture from your exhaled breath and make it available for your inhale. I have used the HME on several trips and to be honest I really can't tell that it does much, and the theory seems to fall apart with a constant flow of air through the tube in one direction......seems almost impossible that any exhaled moisture can travel against the constant flow of air coming through the cpap hose to make it upstream to the HME. Sorta like driving down the interstate the wrong way

Here is a link to the HDM version of the HME, and although it is for the Z1 in reality it is universal and can be used with any standard cpap hose connection and any mask, so not just for the Z1:

https://www.cpap.com/productpage/z1-hea ... -unit.html

But some frequent travelers like Bill-e above says he does get some humidity from the HME, so it may be up to personal experience and your experience may vary.

I just keep some drinking water on the bed side table and have a sip anytime I wake up for a bathroom break, and like anything else, you do tend to get used to no humidity for a few nights on a trip, especially if you're traveling to a higher humidity area.

Be aware that any really small travel machine like the Z1 or the Transcend does take some getting used to for the first few nights, some people adapt well, others don't, and some never do. They do not operate exactly like your regular full size machine, they do require an adjustment period. But for most people that use them enough you do adapt and can use them just fine overtime, the more you use them the easier it is to get comfortable with them.
