Too noisy at my face

Tried it for 2 nights but couldn't get to sleep so had to revert to my big machine. I was so hoping it would work for me as I loved everything else about it
By lisaallen1714,

Love it but louder than I am used to

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.

Z-1 very loud

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,


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,

Z1 Ultra Portable

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,

Z1 Travel Cpap

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.


Nice small machine. However I was unable to use because of no humidifier. I used for about 4 hours and woke up with very soar throat.
By S Holbrook ,

Small, but exceedingly noisy

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,

noisy and missed the mark for travel

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,

Z1 is wonderful

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

Love/Hate relationship

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.
By the Love/Hate Person,

portable cpac

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.
By Jay P,

Nice for Travel; NOISY and EXPENSIVE

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.
By Dave,

An excellent portable cpap.

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,

Z1 travel cpap

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.
