The AirMini offers a compact and lightweight option that is easy to pack and easy to carry. While slightly more expensive than other travel machines, the price point is worth it for travelers who depend on CPAP therapy while away from home. AirMini is especially ideal for frequent travelers and commercial truck drivers. The ResMed AirMini is only compatible with a select number of ResMed AirFit CPAP masks.

“Great Buy!!” – Review by DLL@
My regular CPAP machine is a ResMed. So, I decided to purchase the ResMed AirMini Auto Travel CPAP Machine in January 2020. I used it on a trip I took in February 2020. This was definitely a great purchase. I was tired of traveling with my regular CPAP machine. This AirMini is perfect! It is lightweight & fit great in my backpack.

“Value for Money” – Review by Kiwi Steve
I love this Z2. I find it is quiet & I have no issues with it unless my mask leaks. I use a nasal mask & originally had the wrong size pillow attached, hence the leaks. With the correct size, I now sleep wonderfully in the hotels that I stay in.
“Q-Tube Muffler, Heat Moisture Exchange Unit (HEM), and optional battery” – Review by ClaireWithLove
For the Q-Tube muffler attachment which decreases the sound from the CPAP coming down the hose, it is definitely worthwhile to bring it on a trip with this machine, and it even decreases it nicely with my ResMed AutoSet S9. It makes the sound noticeable quieter.

While this portable CPAP does not offer integrated humidification, it is compatible with most CPAP masks, making it extremely versatile.

Buy NowThings to Remember When Choosing a Travel CPAP Machine
Whether you are new to CPAP or an experienced user, finding the right travel machine can be a challenge. We’ve done our best to compile the following list of things to consider when selecting your travel CPAP.
Travel CPAP Machine Humidification
For many CPAP users, humidification is an essential component of their home therapy. While there are some travel devices that offer integrated (or even optional) humidification, several machines do not. Waterless humidification systems, such as HMEs, are useful but we recommend trying them at home before stocking up for your trip.
Do Travel CPAP Machines Support External Batteries?
Yes, most travel CPAP machines can be plugged into an external battery. Battery life may vary, depending on your pressure settings, so be sure to bring charging cables and, if necessary, a spare battery.
What Type of Filters do Travel CPAP Machines Use?
Most travel machines use either foam or ultra-fine air filters, much like their home counterparts. Inspect these filters before and after every trip to ensure you are getting the best therapy possible. Replace them if dirty or damaged and never attempt using your machine without filters in place.
What is the CPAP Machine Cleaner for Travel CPAP?
While any CPAP sanitizer will work with your travel CPAP device, the Sleep8 offers the same portability and small footprint of many travel CPAP machines. This makes it the ideal companion for users who are constantly on the go.
What You Need to Know About Using Travel CPAP on an Airplane?
Most travel CPAP machines are FAA-approved for use during commercial flights. Prior to your trip, be sure to check with your specific airline for any rules or regulations they may have about CPAP use onboard.
What Types of CPAP Pillows Can You Use with a Travel CPAP?
CPAP pillows are designed to help users get as much comfort as possible out of their CPAP therapy. If you are a user that prefers these types of pillows at home, you can still use them with your travel machine.
How to Buy a Travel CPAP Machine
You can purchase a travel CPAP machine online at The CPAP Shop.
What is the Price and Warranty of a Travel CPAP Machine?
Price and warranty will vary, depending on the CPAP machine. For additional questions, contact our customer care team at 866-414-9700 or email questions@thecpapshop.com.

What Other CPAP Accessories Do You Need for a Travel CPAP?

What is the Pressure Range of a Travel CPAP Machine?
The average pressure range of a travel CPAP machine is 4-20 cmH2O.
What is the Ramp Time for a Travel CPAP Machine?
Ramp is a comfort setting, specific to each user. Most CPAP machines include adjustable ramp times up to 45 minutes. Refer to your user manual or give us a call to learn more about your device’s ramp settings.
What are the Average Noise Levels for a Travel CPAP Machine?
Noise levels can range between 25 and 30 dBA. Some travel CPAP machines are quieter than others.
What is the Power Source for a Travel CPAP Machine?
Travel CPAP machines rely on a DC adapter but can also have a battery source when direct power is not available.
What are the Alerts and Control Settings in a Travel CPAP Machine?
Alerts and control settings will vary by manufacturer. Reference your device’s user manual or call our customer care team for specific information on your machine.
How Often Should You Replace Your Travel CPAP Machine?
Most travel CPAP machines last about 5 years. During that time be sure to maintain other accessories such as masks and hoses based on manufacturer’s guidelines.
How to Set up a Travel CPAP Machine
Your travel CPAP machine will be programmed with your prescription by our technicians prior to shipping. Each device comes with a user manual that provides instructions on use. Most are fairly simple to use and only have two or three buttons.
How Reliable and Durable Are Travel CPAP Machines?
Travel CPAP machines are just as durable as home CPAP machines. However, travel machines are not designed for the same every night use standard machines go through. Still, travel units offer a reliable form of therapy for users on-the-go.
What Is the Difference Between Travel CPAP and Standard CPAP Machines?
The primary difference between travel and standard CPAP machines is the size. Both types of units typically offer the same features and benefits, but travel machines are much more portable.
