    Product Overview

    The Human Design Medical Z2 Auto CPAP Machine is an improved version of the popular Z1 Auto Travel CPAP machine. It's small enough to fit into the tightest spaces and is designed to satisfy the needs of almost any traveler. The Z2 Auto is also FAA compliant and can be carried on an airplane and used in-flight.

    The Z2 Auto CPAP features waterless humidification that uses the humidity from your breath to provide moisture for your sinuses, mouth, and throat. You'll also be able to use your preferred mask for treatment— and not have to compromise.

    Try it Risk-Free for 30 days! If you're unhappy for any reason, you can return it for a full refund!

    Product Features

    Whisper-Quiet Z2 Runs at Only 26 Decibels

    With a new motor 29% quieter than the Z1, the Z2 is designed to minimize the pitch of the motor for optimal comfort. At 26 decibels, the sound the Z2 makes is almost like a whisper, quietly working in the background while you sleep. With the included Q-Tube Muffler, the sound will dampen even further, creating a sleep environment with possibly fewer interruptions.

    FREE Q-Tube CPAP Muffler Included with Purchase

    The Q-Tube CPAP Muffler is designed to reduce machine, hose, and mask noise by quieting the ambient sound generated by therapy. This is especially helpful for anyone who is sensitive to noise. The Q-Tube muffler is included with a purchase of the Z2, and can also be purchased separately.

    One of the Lightest Travel CPAP Machines on the Market Today

    Weighing in at a mere 10.4 ounces, you can comfortably pick up the Z2 with only one hand. It small enough to fit in almost any bag, and can go almost anywhere. It's one of the lightest mini CPAP machines on the market today, and it can be carried wherever life's adventures take you!

    Auto Start / Auto Stop

    To avoid having to reach over to turn on your machine, the Z2 is smart enough to detect changes in your breathing (after putting on your mask) and can automatically start. Similarly, it can tell when you've woken up, and it will automatically stop.

    Waterless Humidification System with HME

    If you're tired of lugging around distilled water every time you travel, you'll be pleased to know the Human Design Medical Z2 Auto can use moisture from your exhaled breath to keep your nose and throat from drying out. This way, instead of the mess and hassle of using a tank of water, all you need to do is breathe.

    Automatic Pressure Adjustments

    The Z2 measures breathing on a breath-by-breath basis and automatically adjusts to the correct therapy pressure. Unlike CPAP machines requiring a manual changing of pressures, the Z2 automatically adapts to your changing needs, meaning your treatment level will never be too high or too low— and can help reduce trips to the doctor for pressure adjustments.

    Advanced Data Tracking with USB and Bluetooth

    With the Z2 you have the option of viewing your therapy data on your Windows computer using advanced software and the included USB cable. You can also track your therapy on your phone using the Nitelog App for Android and Apple. The Z2 will help you track and follow the success of your treatment. The data from the Nitelog App can also help you spot problems early, and it will give you a starting point when talking with your doctor.

    Z-Breathe Pressure Relief Helps Make it Easier to Exhale

    To make it easier to exhale, the Z2 Auto features Z-Breathe technology, temporarily reducing the pressure during exhalation. This helps a person have a more normal breathing pattern and makes it more comfortable to use.

    OPTIONAL: PowerShell with Battery

    Those upgrading from the Human Design Medical Z1 Auto may be pleasantly surprised to know that the Z1 and Z2 PowerShell and Battery will also work with the Z2, so there's no need to buy an additional battery unless desired. The PowerShell with Battery will provide power for approximately one night of therapy if using higher pressure settings. Lower settings will allow the battery to last longer.

    Important Tips

    Connecting to a Windows PC

    You can plug the Z2 directly into your Windows PC by using a USB 2.0 or 3.0 cable, like the one included with the machine, and download your data from there. This feature is not available for Mac devices.

    Tube Adapter Tips

    To avoid damaging the silicone gasket connection on the Z2, please gently remove the tube adapter from the machine. Avoid using excessive force, as this can cause damage.

    Mask Compatibility

    The Z2 Auto will work with any mask, except the specific masks designed for the AirMini.

    HME Compatibility Tips

    Please be advised, the HME Waterless Humidification System will not work with masks that use short tubes. Because the HME unit needs to be close to the face in order to work, short tubes are too long and prevent the HME from working. For optimal compatibility with the HME, please avoid mask designs using a short tube.

    OPTIONAL PowerShell Battery Use & Charging:

    The Z2 battery must be connected to the PowerShell for charging, and the charge information is displayed on the screen. If the machine is not connected to the battery, it will be impossible to know the charge level of the battery.

    Battery runtimes will vary depending on device settings and operating pressure, with higher settings draining the battery faster than lower settings.

    PLEASE NOTE: Do not leave the battery connected to the charger after the device is fully charged. Over time, doing so will cause a decrease in the lifespan and runtimes of the battery.

    OPTIONAL PowerShell & Battery Charge Bars: When the machine and battery are plugged in and charging, the display on the machine will show a series of bars that indicate the battery charge level. Here's a chart showing what the bars mean:

    • 1 Bar = 10-25% power remaining
    • 2 Bars = 25-50% power remaining
    • 3 Bars = 50-75% power remaining
    • 4 Bars = 75-100% power remaining

    Not for Use with Supplemental Oxygen

    The Z2 is not designed for use with supplemental oxygen. Do not attempt to use supplemental oxygen with the Z2 machine as this can cause injury, damage, or loss.

    Power Options

    Medistrom Pilot-12 Lite with Z2 Adapter Kit

    The Medistrom Pilot-12 Lite is designed to work with 12 volt machines like the Z2, provided you purchase the Z2 Adapter Kit. This helpful kit will allow you to make the connection to your Z2 using one cord, and won't require you to use an inverter, giving you extra runtime.

    Portable Outlet CPAP Battery

    The Portable Outlet creates hours of AC outlet power you can take on the road with you when you travel. To connect your machine to the Portable Outlet, all you'll need is your Z2's power supply. Just plug it in, and you're ready to go. It can give you a decent runtime even if you use humidification, and it can power any electrical device.

    PowerShell with Extended Battery

    If you already own the Z1, you'll be pleased to know that the same PowerShell Battery for the Z1 is also compatible with the Z2! There's nothing extra to buy to make your existing battery connect to the Z2.

    The PowerShell Battery is designed for the Z series of CPAP and APAP machines, and can power the Z2 for approximately 8 hours on the highest pressure settings. The PowerShell Battery can also be used as a battery backup in the event power should fail in the middle of the night, keeping therapy running seamlessly for the rest of the night.

    Actual run times will vary, depending on device settings and pressure. Higher pressures will deplete the battery faster than lower pressure settings.

    Freedom Travel Battery

    The Z2 is also compatible with the Freedom Travel Battery. In order to use the Freedom Travel Battery, you must use a 150 Watt Sine Wave Inverter, converting the DC power from the Freedom to AC power the Z2 Auto can use. Keep in mind, using an inverter will drain the battery at a much faster rate than it would otherwise.
