Try Z2 Portable CPAP Machine at home and if you're not completely satisfied, return it for a full refund of the original purchase price. Love it or send it back, it's that simple!

lightweight cpap

The Z2 CPAP builds on the form of the original Z1 with a more advanced, quieter motor and improved software systems. The Z2 is tiny so it fits easily in your hand; and ultra-light at just 10.4 ounces. It is a great everyday machine that is also ideal for travel, packing easily in carry on luggage or any travel bag.

The Z2 CPAP delivers fixed therapy CPAP pressure at prescribed settings between 4-20 CM. For people who prefer to fall asleep with therapy at lower pressure levels, the Z2's ramp feature allows you to start your pressure at a lower setting and ramp it up over time to let you adjust more gradually to sleep therapy.

Z2 delivers a more natural breathing experience with a proprietary feature, called Z-Breathe, that smooths therapy pressure -- reducing spikes in pressure during exhalation and drops in pressure during inhalation -- to deliver more comfortable therapy. Z-Breathe has 3 settings so you can set it to suit your own personal needs.

whisper quiet cpap

The Z2 has a new quieter motor built for sleep so it is very quiet. In fact it's one of the quietest APAPs on the market, producing only 26 dBA on average of sound during operation.

The Z2 CPAP is programmed to stop delivering therapy within seconds of the mask being removed from the face or when a large leak is detected. No more fumbling to find the stop button in the dark.

The Z2 CPAP automatically adjusts to altitudes up to 8,000 feet above sea level; and complies with FAA for use on airplanes. When traveling outside the US the Z2 will convert the voltage automatically so you can continue enjoying safe and comfortable sleep therapy wherever your next adventure takes you. (Plug adapter may be needed outside of North America.)

cpap battery

For nights away from fixed power the optional PowerShell with Extended Life Battery Pack provides an innovative, integrated solution, merging the machine and battery in one convenient package. The PowerShell holds one battery that will last 1-2 nights between charges; and batteries recharge using the Z2's standard power supply so there are no extra cords to worry about. For extra nights away just add additional batteries! The PowerShell can also be used as a backup power supply, automatically taking over during a power outage or blackout.

To ensure you're always receiving your prescribed sleep therapy pressure the Z2 automatically compensates for minor mask leaks. If Z2 detects an excessive air leak, that could be detrimental to therapy, its display screen will warn you to ensure that the leak is corrected promptly.

The Z2's large, backlit LCD display provides information on your current pressure setting, ramp time, power status, and more. With the Z2 you can always check your current therapy status, but don't worry the display has an auto-off function so it won't disturb you as you drift off to sleep.

If you prefer added humidification when using sleep therapy, the Z2 comes complete with an inline HME Waterless Humidification Filter. A unique alternative to bulky water based humidifiers, HME Filters capture heat and moisture from your breathing as you exhale, preserving and increasing humidity to prevent your airways from drying out during therapy.

The Z2 comes with a Universal Tube Adapter and a 48 inch slim tube. If you prefer longer tubing or performance tubing it can be used with that too; and Z2 will work with any CPAP mask on the market so choose your favorite... don't worry it IS compatible!

    I bought a Z2 for camping, based on many good reviews, its light weight and DC capability. I tried it at home on AC power when I received it. Like another poster whose review I had read before buying, I found that the small outlet, and smaller-diameter hose on the Z2, do not allow sufficient air volume to reach my nasal mask. And, increasing the pressure, even to the max, did not provide sufficient flow to prevent feeling a bit "air starved." I am 6'1", 240 lbs. I have never had this experience with another CPAP/APAP device in 20 years of use. So, I returned it pursuant to DHM's generous "try for 30 days free" policy. I plan to buy a different travel APAP (with a full-sized outlet and hose) from DHM, because their service has been great.

    The phone support was wonderful. My questions were answered and additional information gained. I just tested my Z2 and it was easy to assemble . I plan to use while camping in an Airstream travel trailer. Shipping was slower than anticipated but order did arrive in a week.
