The Best Travel CPAP Machines of 2023

Continuous Positive Airway Pressure (CPAP machines) are the gold standard for treating Obstructive Sleep Apnea (OSA). Standard CPAP machines are ideal for at-home sleep apnea treatment, but if you’re planning a trip or travel frequently, you may want to consider adding a travel CPAP machine to your setup to maintain your therapy success while on the go. 

If you have the travel bug and you’re in need of a capable, portable CPAP machine, there are a handful of excellent options on the market to help you achieve the same restful sleep you’ve come to expect at home. Travel CPAP machines have many of the same comfort features as full-sized machines, such as auto start and stop functions, ramp, and pressure relief settings.

Many of today’s travel CPAP machines even offer humidification to keep your therapy air moist and help prevent dry mouth, nose, and throat wherever your travels take you! Traditional bedside units still make for the quietest CPAP machines, but portable options are typically only a couple of decibels louder, allowing you to enjoy whisper-quiet therapy no matter where you are.

With many dreamy options and features to consider, we understand that finding the perfect travel CPAP for you can be overwhelming, which is exactly why we’re tapping into over two decades of product knowledge and expertise to bring you this guide to the best travel CPAP machines.

Key Features of a Travel CPAP Machine

In comparison to standard machines, travel-friendly CPAP machines are small, lightweight, and portable. If it’s your first time traveling with a CPAP machine, it’s important to note that travel machines are TSA-friendly, and most units are FAA-approved for in-flight use. If your flight is short, a small CPAP machine makes disassembly, packing, and reassembly a breeze! 

If your travel machine has the waterless humidification feature, you will also need to pack your machine’s accompanying heat moisture exchange (HME) cartridge, which allows you to leave the distilled water at home. Tiny but mighty, the HME cartridges trap the humidity from your exhaled breath and recirculate it back for your inhaled breath.

It’s also important to understand how a mini CPAP machine is different from a standard machine. A portable CPAP device has some added benefits that will ease some of the stress while traveling. 

A good travel CPAP machine:

• Can Plug Into a Cigarette Lighter to Draw Power From Your Car’s Battery
• Can Be Used With a DC Cable Converter to Allow You to Easily Sleep On-the-Go
• Has Options for Extending the Battery Life—Perfect for Long Flights or Camping Trips
• Is Small, Lightweight, and FAA-Compliant—Safe for Use on a Plane
• Can Still Deliver Quality Therapy Despite Its Small Size

Now that you know some of the standard features of a travel CPAP machine, it’s time to find the right one for you!

Our Review

If you’re looking for a light and compact travel CPAP machine, the ResMed AirMini offers a premium therapy experience in one of the smallest packages on the market. Weighing in at just over three-fifths of a pound, this Auto CPAP makes traveling with humidification easy. ResMed has designed the HumidX™ Waterless Component to allow you to receive all of the benefits of a heated humidifier while leaving the distilled water at home.

This compact CPAP machine fits in the palm of your hand, which makes packing your machine hassle-free. With HumidX, the space-saving AirMini adds moisture while you sleep so that you can cross a humidifier off of your packing list as well. The HumidX Plus is also available for more arid climates and higher elevations where there’s less moisture in the air. Want to continue tracking your sleep on the go? The AirMini connects to your phone via Bluetooth, so you can track your leak rate, usage hours, and events per hour while traveling.

If you’re looking for drawbacks to this travel CPAP machine, there are very few. Some AirMini owners note that the machine isn’t as quiet as they’re used to, but it’s still quieter than some bulkier full-sized machines on the market. You can expect the AirMini to produce a sound similar to white noise, so if a sound machine is usually on your packing list, you may be able to leave it at home. 

Some people have also disliked the lack of data compatibility between the MyAir by ResMed App and the AirMini by ResMed App as well as some shortcomings of the AirMini App’s reporting features. In addition, the AirMini was previously pretty restrictive because it was only compatible with only a handful of specific ResMed masks. However, you now have the freedom of choice thanks to the Zephair AirMini Universal Adapter, which allows you to use any standard hose and mask with the AirMini device. As far as HumidX and HumidX Plus are concerned, while helpful, these waterless humidification cartridges can only be equipped on the N20 for AirMini, N30 for AirMini, and P10 for AirMini masks. 

Overall, the AirMini is an industry leader in travel CPAP machines for a reason. We recommend this device for frequent flyers that don’t mind a higher price point or sleeping with white noise.

Our Review

The Transcend Micro Auto from Somnetics is the latest travel CPAP machine on the market. Weighing in at less than half a pound and measuring about the size of a baseball, the Transcend Micro is redefining convenience and has taken the mantle of “World’s Smallest CPAP” away from the ResMed AirMini. Small yet mighty, the Micro Travel CPAP features automatic pressure adjustments, ramp technology, automatic start/stop, and an adjustable pressure relief setting just like you’d expect from a full-sized unit. 

While this list of features is already impressive for a device of this size, what really sets this machine apart from the rest is the convenient drying mode, waterless humidification, near-universal mask compatibility, built-in sound and vibration dampening technology, and the included WhisperSoft Muffler, which helps reduce the noise coming through your CPAP tubing. The 30-minute drying mode is especially helpful when you are going off-the-grid and can’t hang your mask and hose to dry throughout the day. The Micro’s drying mode helps prevent condensation and contamination build-up, which deters the formation of mold, bacteria, and unwanted odors.

Perhaps, most importantly, the Transcend Micro is compatible with virtually any CPAP mask, except for masks that are specifically designed for other machines, such as the AirMini-only masks like the AirFit N30 for AirMini or the AirFit P10 for AirMini. In addition, the Reusable PureFresh Air Filters (coming soon) are designed to last around six months between replacements, but you’ll want to replace them sooner if they show signs of wear and tear or if you are traveling to a dusty, dry climate. Gently hand wash and dry your filter every two weeks or so to keep it fresh.

In terms of drawbacks, there are a few to be considered. Mainly, you will need to use the tubing included with the Micro since the end that connects to the device is much smaller than a typical CPAP air outlet. For those that prefer heated humidification over waterless humidification, you’ll also be out of luck with the Micro as it doesn’t support a full humidifier, unlike the Apex XT Auto featured below. There have also been some issues with getting the MySleepDash companion app to be fully operational, but since this is a relatively new technology for Transcend, we expect that the app experience will go more smoothly after a couple of software updates and some feedback from Micro owners. We will update this article once that occurs.

Overall, the Transcend Micro is a welcomed addition to the travel CPAP market and one that we believe will stand the test of time. Please note that at the time of this writing, the Transcend HMEs for waterless humidification and the replacement air filters are not yet in stock, but we will be updating this article as soon as they’re available. The Transcend HME is required for waterless humidification and will not be able to provide moisture to your therapy air without it.

Best For Camping: Human Design Medical Z2 Auto Travel CPAP

Machine Features

	HDM Z2 Auto Travel CPAP
Noise Level	26 Decibels
Machine Weight	0.65 lbs
Operational Altitude	Up to 8,000 Feet
Compatible Humidifier?	HME Waterless Humidification
Dimensions	6.4” L x 3.3” W x 2” H
Average Customer Rating	4.3 Out of 5 Stars

FAA-Approved?	Yes

Our Review

While the AirMini is slightly more compact, the HDM Z2 Auto Travel CPAP Machine is actually a little lighter, weighing just 0.65 lbs! It’s small and compact, making it the perfect travel companion. Like the AirMini and Transcend Micro, the Z2 also uses a proprietary waterless humidification system, allowing you to leave your bulky humidifier and distilled water at home. 

Without having to compromise on size, the standout feature that makes the Z2 exceptional for camping is the machine’s display screen, which both the AirMini and Transcend Micro lack. Why is this important? You can access your therapy information directly on the machine itself without needing cell phone service to use the compatible mobile app, NiteLog 2.0, which means you can adjust your therapy while you’re off the grid. 

The Z2 comes with the included Q-Lite CPAP Muffler, which helps reduce the noise from your mask and tubing. While you’re camping and sleeping under the stars, the Q-Lite CPAP Muffler allows you to enjoy the peaceful nature sounds that can put your soul at ease. While a good travel CPAP will do its best to operate quietly, there are some fundamental limitations in sizing that can prevent a portable CPAP from being as quiet as a traditional bedside CPAP machine. This additional commitment to a peaceful night’s sleep is what we love about the Z2. 

Instead of a traditional humidifier, the Z2 Auto Travel Machine also comes with a Heat Moisture Exchange (HME) unit, which uses the moisture from your exhaled breath to humidify your incoming therapy air. While this isn’t as effective as the humidification you may be used to with your at-home machine, it is ideal for traveling light. 

Overall, the Z2 is a quiet and reliable travel CPAP device that’s perfect for any traveler, backpacker, or camper and is easily one of the cheapest travel machines available.

Our Review

While this machine isn’t exactly new to the market, it’s enjoyed a few years of standout reviews from thousands of satisfied owners, which makes us more than confident to include it on our list of the best travel CPAP machines. Whether you’re looking for a dedicated travel machine or one for your nightstand at home, the Apex XT Auto is a capable option that is great for filling both roles. 

Its integrated heated humidifier has six heat settings to provide full humidification throughout the night, making it the only travel machine on this list that doesn’t rely on waterless humidification. If you’ve come to love the humidification feature on your standard CPAP machine, then you don’t have to go without it when you leave home thanks to the Apex XT Auto. This compact-yet-capable CPAP machine provides you with moistened therapy air to prevent dry mouth, throat, and nose. While this makes it slightly bulkier than other travel machines overall, you can always leave your humidifier behind and opt for waterless humidification instead by using Heat Moisture Exchange Units, which won’t work with short-tube masks, such as the Swift FX or AirMini-specific masks like the P10 for AirMini. The XT Auto features a built-in power supply, helping to keep the power cord small, light, and easily storable. This travel APAP also offers three levels of adjustable pressure relief to lower the incoming pressure during exhalation for a more natural breathing experience.

Where this machine shows its age, unfortunately, is in its comfort features. The ramp feature is only available in fixed-pressure CPAP mode, and since there’s no automatic start/stop function, you’ll still need to press buttons to start or stop your therapy—though we weren’t particularly bothered by this. The unit also features a programmable clock with an alarm function, which may be useful to you if you’re leaving your cell phone behind. For us, the alarm function also means your alarm clock is one less thing to pack or have on your nightstand. If you’re someone who needs detailed sleep reports, this machine may not be right for you; many customers have pointed out that while data is provided on the machine and is downloadable via an SD card, it displays the Apnea Index (AI) and Hypopnea Index (HI) separately as opposed to the cumulative Apnea Hypopnea Index (AHI) that’s offered by other CPAP machines. This isn’t necessarily a deal-breaker, though, as it also displays your Snoring Index (SI) and Flow Limitation Index (FI), and we’re content with its ability to download recent sleep data to an SD card. 

Overall, the XT Auto is a compact and capable machine that is ideal for those who prefer to travel with full heated humidification or are simply looking for an affordable bedside machine for at-home use. This robust, low-frills APAP is FAA-approved for in-flight use and comes with a standard two-year warranty. 

Apex XT Auto Travel CPAP Features and Benefits:

• Adjustable Integrated Heated Humidifier Included
• Compact Size Makes It Travel-Friendly
• Built-In Alarm Clock Feature
• PVA Adjustable Pressure Relief
• Travel Bag Included
• Simplified Screen and User Interface

Drawbacks:

• Ramp Feature Only Available in CPAP Mode
• Basic Compliance Reporting Displays AI and HI Instead of AHI
• Lacks Auto Start/Stop Function

Compatible Humidifier: XT Heated Humidifier (Included With Machine) 

Best Battery: Portable Outlet UPS Battery

Other Battery Options: 

• Zopec Explore 4000
• Zopec Voyage Power Outlet 2

Consider the Following Before Purchasing a Travel CPAP: 

When it comes to finding your ideal travel machine, we think it’s important that you are armed with the knowledge to make the best purchasing decision for your specific sleep apnea therapy needs. For this reason, we’ve created a handy buying guide of things to consider when shopping for a travel-sized CPAP machine. 

Portability

The very first thing you should consider is what situations you’ll most commonly be using your new CPAP machine in. Frequent and infrequent travelers have different needs; some people may want a dedicated travel machine while others may simply prefer a bedside unit that happens to be easy to travel with. 

Most dedicated travel CPAP machines are FAA-approved for in-flight use, but more traditional units may not be. Someone who does more camping than flying may prefer a more barebones unit that’s simple to operate when off-the-grid over a machine with more bells and whistles.

Price

In terms of pricing, travel CPAP machines are typically more affordable than their full-sized counterparts—though you can still expect to spend around $600 to $900 for a compact machine from a reputable brand. Many of these travel machines pack in as much value as they can, and in comparison to your bedside unit (especially if both machines are from the same manufacturer), most travel machines will feature the same or similar comfort features. They will also commonly include a travel case or pouch as well as any power accessories you’ll need to get it running. Most travel machines will also let you use the same mask as your home machine, saving you some money on an additional mask or tubing.  

Doctor’s Recommendations

Since you can’t buy a CPAP machine without a prescription, you may have already talked with your healthcare provider about the best equipment for your needs. Whether there are specific machine settings or comfort features you require or there’s a particular mask style that works best for you, be sure that the machine you’re considering will be able to deliver the therapy you deserve.

Sound Level

CPAP technology has come a long way in reducing the sound level of portable CPAP machines, and most modern devices are only slightly noisier than their full-sized counterparts. Some machines, like the HDM Z2 and Transcend Micro, even include tube mufflers for a more whisper-quiet experience. Some owners report that their travel machines, while quiet, do operate at a higher pitch than their home machine, but most people find themselves easily drifting to sleep with a brief adjustment period or a good pair of earplugs. If you prefer to sleep with a bit of sound anyway, you might find that your travel CPAP machine doubles as a dreamy white noise machine, too! 

Machine Type

If you’ve been using CPAP therapy at home on a different device, there’s a good chance that your travel CPAP machine will give you a different experience. Due to size constraints and engineering hurdles, a pressure setting on your bedside unit may not behave the same way on a travel machine. Even if both are set to 12 cm H2O, the experience still may be different. 

For this reason, we recommend traveling with an APAP machine. It’s much easier to let the machine react to your needs rather than relying on a set pressure that may not be enough for you at the moment or feels weaker from your travel machine.

Comfort Features (Ramp, AutoStart, Pressure Relief, etc.)

Outside of doctor’s recommendations, you may personally prefer or even require specific comfort settings such as ramp or auto start/stop. Be sure that the machine you’re considering has the features that are most important to you for a restful sleep apnea therapy experience. 

This also applies to humidifier usage; if you’re someone who requires a standard humidifier or if you’re traveling to a drier climate where you might need one, your options will decrease. However, if you’re content with utilizing waterless humidification, you can save yourself from having to pack distilled water and travel lighter in the process.

Data Tracking

If data tracking is essential to you, you might consider a more high-tech option with real-time reporting to the machine’s compatible cellphone app. Keep in mind that some travel machines can’t sync or view data until you’re back home with your PC.

Accessories

Accessories for a travel CPAP device include things like external batteries for charging or operating your machine, a travel case or carrying bag to protect your equipment, tubing or mask adapters (such as the Zephair Universal AirMini Adapter), or waterless humidification devices (heat moisture exchange units). When you decide on your travel machine budget, be sure to factor in the cost of any additional travel accessories you’d like as well.

Warranty

Most travel machines have a two-year warranty, though there are some longer and shorter exceptions. Be sure to check the manufacturer’s warranty for your device to be clear on whether or not it protects you in situations you may find yourself in while traveling. 

FAA Approval

As we mentioned earlier, most travel CPAP machines are FAA-approved and TSA-friendly, though it never hurts to double-check with the manufacturer’s specifications. Some airlines will also have different rules/requirements than others, so be sure to inquire about any policies they may have regarding CPAP machine use in flight.  

Power Consumption/Requirements

Most machines can run off of outlets in almost any country with the appropriate travel plug adapter. Still, it’s always a good idea to be familiar with where you’re traveling and the power draw of your machine. For camping and off-the-grid activities like RV travel, it’s also important to know if you’ll need to add any adapters or inverters to your CPAP setup. 

Frequently Asked Questions

How Much Do Travel CPAP Machines Cost?

Cheaper travel CPAP machines start in the neighborhood of $600 and can be as expensive as $1,200. On average, you’ll spend about $800 for a quality travel machine.

Does Insurance Cover the Cost of a Travel CPAP Machine?

While it’s always encouraged to check these specifics with your insurance company, many will not cover the cost of a travel CPAP.

Can I Use a Regular Mask With My Travel CPAP?

In most cases, yes! Most travel machines will include a hose or mask adapter or be universally compatible. We also offer additional adapters to work around some machine restrictions.

Can I Use a Travel CPAP at Home?

Yes! A travel CPAP machine is perfectly capable of delivering quality therapy as a full-time home unit. It is worth noting, however, that parts in your travel machine may wear more or show their age more quickly than on a larger unit. You should also consider how important a suite of comfort features is to you, as travel machines may not have the same capabilities in that regard. 

Can I Use a Travel CPAP In-Flight?

Yes! If a device is FAA-approved, then you can use it during the flight as long as you meet the requirements of your airliner. Examples of some requirements would be requiring a 48-hour approval notice before the flight or requiring a separate CPAP battery with a capacity equal to or greater than 150% of the expected flight time. Check with your airline for more details.

Final Thoughts

Wherever and however you’ll be traveling, there is a compact CPAP machine suitable for your trip! Luckily, you don’t have to sacrifice a good night’s sleep without proper sleep apnea therapy on your next adventure.

Remember: The best travel CPAP machine is the one that will give you a therapy experience that’s closest to what you’re used to getting at home. Traveling can disrupt the usual cadence and rhythm of our lives, initiating a stress response in the body. By finding a semi-familiar product that will help you maintain your CPAP routine on the go, you’ll be setting yourself up for a healthier and happier trip overall. 

Safe travels!
