This is the smallest, lightest, quietest machine I could image. I had a remstar plus before and thought it was pretty compact but this blows it away. This isn't cheap but for anyone who travels even occasionally you NEED this.

New purchase, Z1 CPAP from HDM
5 out of 55 out of 55 out of 55 out of 55 out of 5
Great service and quick shipment from cpapXchange. The Z1 is so quite you almost don't realize it is ON. I have been very pleased with my purchase and would recommend anyone that has limited space and/or travels to highly consider purchasing a Z1. Also the Wisp Mask is a good choice, but you may have your own preference of mask. cpapXchange can help you achieve an excellent experience with your prescribed therapy.
By J Sexton, Cape Cod, MA

Small,Yes! Thats it.
3 out of 53 out of 53 out of 53 out of 53 out of 5
Very cheaply made. Hard to get filter cover off. The power case came bent. Battery and CPAP hard to get in, then slip out. I thought this would be great. Such is life.
By Michael, nYC

2 out of 52 out of 52 out of 52 out of 52 out of 5
HDM said that the battery would last for 2 nights at my pressure of 9cm of water, it doesn't. I have tried it twice on battery power. I got 6 hrs on the first charge and 7 hrs on the second try. Also if the CPAP & battery are in the power shell the machine is on constantly draining the battery. This is a poor design feature in my opinion, which just increases the bulk for camping and negates the power shell protection claim.
By Richard, Ohio

Almost great...
4 out of 54 out of 54 out of 54 out of 54 out of 5
Worked well for me on a long trip to Asia BUT... there should be a real on/off switch that cuts off the battery. Having to struggle to remove it between uses is a real chore for those of us with arthritis. I found that I didn't need to use the humidifier I purchased with the machine, but it would n't have mattered since it is NOT adaptable to worldwide current like the Z1. I dread changing the air filter... that too is a real chore. By the way, be sure to get approval from your airline if you plan to use the Z1 with battery on the plane... Japan Airlines really was strict. I had to show it EACH segment of my trip!

Z1 Ultra Portable CPAP
5 out of 55 out of 55 out of 55 out of 55 out of 5
I have had this new cpap for a couple of weeks. I haven't had the chance to take it on a trip yet, but I have tried it out at home. It is great! I had no trouble adjusting to it. It is a little noisier than my bigger machine, but I don't have a problem with that. Can't wait to take it on a trip and carry it in my small suitcase. Yea! No more big bag!

Z1 Ultra Portable CPAP System Much Noisier Than Advertised
2 out of 52 out of 52 out of 52 out of 52 out of 5
The HDM Z1 portable CPAP machine is a good looking, light (10 ounces) unit that is so small it easily can be held in the palm of your hand. Unfortunately, it does not live up to its claim of very quiet (26 dBA) operation. The 26 dBA measurement must have been made at the machine which itself is relatively quiet, emitting only a soft wining noise. At the level of the mask, the unit is much louder and interferes with rapidly falling asleep. The problem is not related to the mask, as using the same mask on a Resmend S9 CPAP machine produced almost no sound. I was able to reduce the sound somewhat by using a 6 foot tube rather than the 4 foot tubing supplied with the unit and adding the in-line HME filter between the tubing and the mask, but it still takes me a good 30 minutes to fall asleep because of the noise. I would recommend this system for travel, particularly air travel, where size and weight are important, but not for everyday use.

Product is fabulous. Light and great for travel. Almost as quiet as my REsmed S9. your service was just great.
By Harvey, Boston

Was skeptical, but now am truly impressed.
5 out of 55 out of 55 out of 55 out of 55 out of 5
I knew that I wanted a portable device for traveling, but was concerned whether it would work effectively enough - and be quiet enough - for occasional trips. So far, I am very satisfied on all counts. It would be great if it also included the Auto-CPAP type feature found on the ResMed machine which I use at home. Overall the Z1 is a good value and I'd recommend without reservations. I also want to specially recognize cpapxchange for their great customer service. Nat was helpful and patient, which meant a lot to me.

Great Service & Great Equipment!
5 out of 55 out of 55 out of 55 out of 55 out of 5
Thanks cpapXchange for a great value on an amazing device! I received it in one day after sending you my Rx, although it took me about three more weeks to actually open the box and use the Z1 I purchased! What an amazing little machine! I'll probably be purchasing another for my go bag. Thanks again!

Z1 Ultra Portable CPAP system
5 out of 55 out of 55 out of 55 out of 55 out of 5
Amazing device! Small and perfect for travel... No more big bags to carry. Thus this one of my preference to buy a travel size, although I just tried one night and it works perfectly. For the quality of plastic case overall is not impressive as it looks cheap material... It would be better if there was an upgrade for firmware to make it auto set (Auto CPAP).

Portable & Functional for Travel

Light weight and adequate for the traveler. I did not get the extra battery as I feel this would not be unit for travel. Excellent service and communication.

A Great Compact Machine
5 out of 55 out of 55 out of 55 out of 55 out of 5
I purchased this machine for travel as I frequently only take a small roller bag on the aircraft. This machine is both light and compact, but does everything my larger machine does. It is also quieter than my larger machine. Very pleased...
By Dwight, Miami

5 out of 55 out of 55 out of 55 out of 55 out of 5
Great product, light weight and compact for a road warrior. I see many travelers with the large CPAP bag and can imagine still having to travel with that large CPAP. Great and easy to use product.

Z1 Ultra Portable CPAP System
5 out of 55 out of 55 out of 55 out of 55 out of 5
Travelling with my bulky Philips CPAP is so frustrating getting through airport security and setting up to for sleep at night. I was excited to find a smaller travel unit but I was skeptical that a machine so small could provide me with adequate pressure for my severe sleep apnea. I have been testing this unit for the last 2 weeks and I can say that it's amazing. It works without water for the humidifier, and although it is a little louder than my other unit it is so small, compact and easy to use and I slept all night. I especially like the convenience of the battery pack. I live in south Florida and due to summer storms we lose power a lot. Nice to be able to travel with a smaller CPAP in my carry on. I was very happy with cpapXchange. Easy to order, and very fast shipping. Thanks! I truly enjoy this product!

Excellent travel CPAP
5 out of 55 out of 55 out of 55 out of 55 out of 5
I am a pulmonary physician at a university medical center and a long time CPAP user so not only do I get to try all products and "look under the hood" but I also travel over 150K miles per year to lecture at other medical centers so I am on long flights a lot. This is the best travel CPAP I have used and I've tried a half dozen. It is comfortable and delivers. My wife and I are very noise tolerant (compared to my snoring, an earthquake is a gently rocking in the cradle) so I am not one to comment on this. Note that what works well for me, may not be best for you. I am also looking into lightweight humidifiers for bedside use when I travel. The real test of this Z1 will come next month when I spend 4 days in the Amazon rain forest with my family ...
By BKR, Virginia

Great little unit
5 out of 55 out of 55 out of 55 out of 55 out of 5
The Z1 preformed well. It is as quiet as my other CPAP machine but MUCH more portable. Less to pack when traveling. The battery does not seem to last long enough but I purchased the car charger to keep battery charged when not near an outlet. I am very impressed that I do not need a water reservoir when using the HME filters. No dry throat. Great product!
By Robert, Montana Big Sky Country

Small and Easy
4 out of 54 out of 54 out of 54 out of 54 out of 5
It is great for traveling. So much easier to get through the airport and into your suitcase. The only issue is...Makes a lot more noise than my standard machine and therefore is a little hard to get used to.
By David P, Lake Charles, LA

Need humidity
3 out of 53 out of 53 out of 53 out of 53 out of 5
My Z1 CPAP came just in time for our motorcycle weekend trip. I tried it out the night before we left and it dried out my nose/throat to the max even at the height of humid summer. It was very quiet and easy to pack. I did not get the battery pack. I have a pressure of 6. I don't understand how any technical person would think that a little sponge would capture your breath's moisture and give it back to you!! They need to figure out how to incorporate humidity so that customers don't wake up to a dried out nose and back of the throat. I woke up to the pain and had to stop using it. I could not wait to get home to my big bulky CPAP with its humidifier. The ordering process was very easy and very friendly.
By S. Paul, Seattle

really disappointed
1 out of 51 out of 51 out of 51 out of 51 out of 5
The noise level at the mask is much louder than I expected. I might be able to get past that when traveling because of the advantage of the size. However, there is a whistle when I exhale that I can't get rid of. Different masks, different tubing, same result. Too annoying to use. My wife hasn't had a problem with any of the multiple cpaps or masks that I have used over the years, but this whistle keeps her awake.
By Gard M, NY

5 out of 55 out of 55 out of 55 out of 55 out of 5
The Z1 is an impressive CPAP. It was just what I was looking for with it's compact size for travel. The only thing that took a little getting used to when you inhale it revese up. The change in the sound is what took some getting used to. Other than that I'm 100% satisfied with the CPAP and CPAP Exchange.
By Kent, Florida

Excellent for travel
4 out of 54 out of 54 out of 54 out of 54 out of 5
Great little machine. My husband says it is quiet. However it is louder than my Resmed that I use at home. Seems like the sound is coming from my mask, but there are no air leaks. Perfect for travel.
By Ms. Ham, California

Small but mighty... good that is!
4 out of 54 out of 54 out of 54 out of 54 out of 5
I have used a GoodKnight CPAP for 10 years and just got tired of traveling with this moderate sized machine... especially when I saw the Z1. The first night I used the Z1 I woke with a headache like those I used to get before I started using a CPAP. For some reason the Z1 had to be set 1 cm/H2O higher than my GoodKnight for the same relief. I wish it didn't require an adapter for the hose and that the power adapter was not in two different pieces but otherwise, this is a dream.
By MJay, WA State

Loving my Z1 Ultra

This little CPAP is fabulous! It even lights up with a green night light when moved to assist in settings or to turn off or on. The exhaust breath relief feature is a true joy as well. Portable, light weight and powerful. A real Gem!
By Marco, North Carolina Mountains

High Velocity air Makes it very noisy
3 out of 53 out of 53 out of 53 out of 53 out of 5
I bought this for travel. The unit it self is very quiet. But there is a large amount of "wind" noise at the mask. This is true compared to my larger unit using the same mask. I check the pressure and it is the correct. It is like the air is moving at a much higher velocity than my normal unit. I have no other explanation but it is quite distracting.

Z1 travel cpap
5 out of 55 out of 55 out of 55 out of 55 out of 5
What a pleasure to use this device for travel instead of the bulky Respironics I use at home and used to have to lug around. Everything arrived complete and intact with clear instructions and a travel bag that held all the equipment. Altho some users have complained of noise, neither my wife nor I noticed a problem. The online chat prior to purchase was quick, responsive and helpful. I was completely satisfied with the product and the process from beginning to end.

An excellent portable cpap.
4 out of 54 out of 54 out of 54 out of 54 out of 5
I keep this in Myrtle Beach where I travel 4-5 times a years. It's nice not having to pack up my Respironics machine and haul it on a plane. I have found some tricks to make it work better: There a tendency to wake up in the middle of the night with dry mouth, so I keep a few sugarless hard candies under the pillow and pop one in my mouth. I also keep a sipping glass with a straw if I need a sip of water.
By GerryS, Centennial, Co

Nice for Travel; NOISY and EXPENSIVE
5 out of 55 out of 55 out of 55 out of 55 out of 5
I like this a lot for travel of several days in places with electricity (Europe, Middle east, Canada, US, Nicaragua, etc). It is quite noisy; this needs some attention in updates. Also, the rechargeable battery is outrageously expensive. Come on, we now more about rechargeable batteries.

portable cpac
5 out of 55 out of 55 out of 55 out of 55 out of 5
Excellent phone service in explaining procedure. Cpac arrived next day after doctor fax. In perfect shape. I have set it up and made sure it is working. I have not used it yet. Waiting for over night trip since it is an ultra light weight model. Only complaint is it did not come with a case and none seem to be advertised.

Love/Hate relationship
4 out of 54 out of 54 out of 54 out of 54 out of 5
Great for travel, love the battery back up function for when the power goes out, love how it fits in my carry on! What I hate is the Z-Breath function is not as good as the EPR on my Resmed, no where close to the correct pressure relief. I have tried all the settings. And I hate that I need to pull the battery out or else it drains- a simple on/off switch would have been much nicer. I don't use this one much and fell like I wasted my money, mostly due to the pressure relief. But I love the size for travel.

Z1 is wonderful

I am traveling and so appreciate how the z1 can be used everywhere (flying, camping, etc.)
By Rod, Antioch, Calif.

noisy and missed the mark for travel
3 out of 53 out of 53 out of 53 out of 53 out of 5
I love the compact size and light weight. But the is a lot of noise - seems like at the mask level rather than motor noise. Same mask with my at home resmed is virtually silent. The lcd screen is not protected at all and the unit only lasted a couple trips before it was not readable at all. If you are going to travel with it, find some kind of padded case. Because of the two things, I'm very disappointed in it.
By Dwight R, Tampa

Small, but exceedingly noisy
3 out of 53 out of 53 out of 53 out of 53 out of 5
As advertised, the Z1 Ultra Portable CPAP is indeed, ultra portable. It is tiny and exceptionally light. However, I have to use earplugs due to the excessive noise at the mask level, which has been experienced by other users. For this reason, I can use it when traveling alone, but not as an everyday machine, as it would keep my wife awake. I am disappointed for this reason, but glad to have an option for great portability.
By Ken, TX

Z1 Travel Cpap
5 out of 55 out of 55 out of 55 out of 55 out of 5
I mainly ordered the z1 to use in our fifth wheel but also liked the idea of not having to tote a much larger cpap on the occasional trip by air. The size is amazing for what it does. It is a little noisy but I soon got used to the sound. I love the idea of traveling with it and having it for a backup should my other machine fail.

Z1 Ultra Portable
5 out of 55 out of 55 out of 55 out of 55 out of 5
Great little CPAP and works well. A little bit noisier than my other travel CPAP but the size difference is a major factor. The hose and mask takes up more room. When space is at a premium (I travel by Motorcycle a lot), this CPAP takes up so little room.
By Ben, Baltimore

2 out of 52 out of 52 out of 52 out of 52 out of 5
Great little unit, love the battery packs -so perfect for travel, BUT although the unit is silent, it is extremely noisy at the mask.
By Mitzi, Michigan

Z-1 very loud
3 out of 53 out of 53 out of 53 out of 53 out of 5
I bought the Z-1 to take on vacation so I wouldn't have to lug my larger CPAP around. While very compact and easy to carry on the plane, the first night it was so loud I hardly slept. I purchased a fan the next day to wash out the noise, but the next three nights I slept with pillow over my head. Easy to travel with, but loud if you are a light sleeper.
By De from NJ, NJ

Love it but louder than I am used to
5 out of 55 out of 55 out of 55 out of 55 out of 5
I love how small the cpap is. It fits into a little pouch the size of a crown royal bag. It's only downfall is the high pitch noise and whistle from the motor. I don't mind it but it keeps my wife awake. I travel alone and it even gets to me some nights. I use the muffler and a Resmed P10 nasal mask. The noise travels up and out the mask. It will quiet down some if you use the moisture filter.
