Best travel CPAP machines of 2026: compared by mask fit and full cost

By SleepApneaSelect. Prices and details checked October 7, 2026. We compared maker documents and seller listings. We did not test these machines. Seller links on this page are unpaid. Advertising disclosure.

The best travel CPAP fits your prescribed therapy and the mask you already wear.

Start with the Transcend Micro 510 if your mask has a standard hose connection and you want the smallest of these three machines. It weighs under 0.5 lb, device only, and costs $829 with a hose, case and waterless humidity kit in the box. Check your mask's humidity fit below.

Start with the ResMed AirMini if you wear a ResMed F20 or N20 and want the waterless humidity setup ResMed lists for that mask. F30 also connects, but without HumidX. The machine is $919. You also need the correct tube and connector. The setup packs shown here cost $56 to $62 unless you already own the required parts.

The Luna TravelPAP is a third choice at $825. It takes standard masks but has no humidifier.

And if you travel once or twice a year, the machine you already own may be the right answer.

Using oxygen with your CPAP, or a bilevel (BiPAP) or ASV machine? AirMini, Micro 510 and Luna TravelPAP must not be used with supplemental oxygen. These three are CPAP and auto-CPAP machines only; they do not replace bilevel or ASV therapy. Ask your prescriber and equipment supplier for an appropriate travel setup.

The best travel CPAP machines at a glance

All three travel machines run in CPAP or auto-CPAP mode from 4 to 20 cm H2O. Auto-CPAP (also called APAP) means the machine changes pressure during the night inside the range your prescriber sets. Since all three cover the same range, pressure does not pick a winner here.

The AirMini's $919 does not include a hose or a mask. Pair it with the F20 setup pack, $56 (opens in a new tab) or N20 setup pack, $62 (opens in a new tab) for the examples above. F30 uses the $56 pack's shared connector without its HumidX F20 cartridge. The Luna does not include a humidifier. The cost table shows the complete baskets.

Will a travel CPAP work with your mask?

Check two things. They can have different answers.

1. Does your mask connect to the machine's hose?
2. Does that setup support waterless humidity?

Many CPAP masks use a standard 22 mm hose connection. The supplied Micro 510 and Luna TravelPAP hoses have a standard mask end. Check the exact mask model and version in its instructions or with your supplier; the shape alone does not establish compatibility.

The AirMini uses its own tube and its own connectors. ResMed lists only these masks for it: AirFit and AirTouch F20, AirFit and AirTouch N20, AirFit F30, AirFit P10 for AirMini, and AirFit N30 for AirMini. Source: ResMed (opens in a new tab)

"Fits" here refers to the standard versions of the named masks, using the supplied or recommended tubing, unless the row says "for AirMini." It means the parts connect. It does not mean the mask seals well on your face or suits your therapy. That part is between you and your equipment supplier. ResMed confirms that the F20/F30 connector (opens in a new tab) supports both full-face mask models; the HumidX F20 cartridge remains F20-only.

Which AirMini masks get waterless humidity?

• F20: yes, with the HumidX F20 cartridge.
• N20: yes, with HumidX or HumidX Plus.
• P10 for AirMini and N30 for AirMini: yes, with HumidX or HumidX Plus.
• F30: no. ResMed says waterless humidification is not available with the AirFit F30.

HumidX Plus is the stronger version. ResMed makes it for dry places and high altitude. Source: ResMed (opens in a new tab)

What about adapters that make any mask fit the AirMini?

Other companies sell them. They may join the parts. But ResMed does not list those setups, and humidity may not work through them. We don't count an adapter as a fit. If you want to try one, ask your supplier about your exact mask first.

What a complete travel CPAP setup costs

Compare the whole setup, not the machine price. These are our sums of posted prices from October 7, 2026. They leave out tax, shipping, discounts and insurance. They are not quotes.

If you plug into a wall outlet

AirMini, Micro 510 and mask prices are from CPAP.com. The Luna price is from Lofta. "Your own mask" assumes a compatible mask and a machine configured to your prescription. The $42 F30-only pack was sold out when checked; the F30 basket uses the available $56 pack's shared tube and connector instead.

Here is what that means if you own an F20. The AirMini setup is $975. The Micro 510 is $829. That is $146 more for the AirMini. For that $146 you get a humidity setup ResMed lists for your exact mask. Whether that is worth it depends on how much you need humidity.

The new-mask rows are price examples only. The $155 price is for the complete AirFit F20 in the standard/medium selection, not a frame without headgear. The F20 has magnetic clips. If you or anyone in close physical contact while you use the mask has an implant or medical device, read ResMed's magnet contraindications and warnings (opens in a new tab) first. Your supplier should help you choose mask type and size. Complete F20 offer (opens in a new tab)

• AirMini: machine, power supply, filter, drawstring bag. No hose. No mask. Source: the priced CPAP.com offer (opens in a new tab)
• Luna TravelPAP: machine, slim tube, power adapter, storage bag, filters. No humidifier. Source: React Health (opens in a new tab)

Two things that change the price

A larger bundle can cost more than the minimum setup. Transcend's Micro 510 Power Bundle was $1,328.85 on its site. The machine ($829) plus the battery ($349.95) is $1,178.95. The bundle costs $149.90 more and adds extra hoses, cartridges and bags. Buy it only if you want those extras. This compares the larger bundle with a smaller purchase, not the same contents bought separately. Source: Transcend Power Bundle (opens in a new tab)

A code can change what you pay. On October 7, Transcend's own site showed a banner code, 25OFF, for 25% off. We did not test its eligibility at checkout. If it applies to the $829 machine, the item price would be $621.75 before tax and shipping. That is conditional arithmetic, not a verified sale price. Check the current terms before you pay. Source: Transcend's displayed offer (opens in a new tab)

Can you return it after you try it?

This matters more than a $20 price gap. A travel CPAP can sound and feel different from your home machine.

If noise or dryness could make you give up on the machine, buy where you can send an opened one back. For example, Lofta's 15% fee on a $825 Luna is $123.75, before return shipping or other nonrefundable charges. A machine return policy does not make every separately purchased part refundable.

Transcend Micro 510: best for keeping your current mask

The Micro 510 is the smallest machine here. It is 3.6 x 3.6 x 2.4 inches and weighs under 0.5 lb, device only. Its manual lists 0.49 lb (223.4 g); the product page gives 0.48 lb. Sources: Transcend product page (opens in a new tab), Micro 510 manual (opens in a new tab)

Why it's on the list

• Its hose ends in a standard connector, so most masks fit.
• The $829 kit is complete for a compatible mask you already own, once configured to your prescription. Hose, muffler, hard case and a humidity cartridge are in the box.
• Transcend makes a battery just for it.
• It has a 3-year limited warranty on the machine. The other two have 2-year limited device warranties. Transcend warranty (opens in a new tab)

What to know before you buy

• Humidity comes from AirMist, a waterless insert. There is no water tank and no heat. CPAP.com's listing warns it may work poorly with short-tube and top-of-head masks.
• There is no screen. The machine has buttons for power, ramp, drying and Bluetooth. MySleepDash is optional: it shows therapy data and reports and lets you adjust supported comfort features. Prescribed pressure settings are programmed separately and cannot be changed through the app. Source: MySleepDash (opens in a new tab)
• The machine end of the hose is Transcend's own shape. You can't swap in the heated hose from your home machine.

Micro 510 or the older Transcend Micro? Both are sold. The original is listed at $769 direct from Transcend, with a 2-year device warranty. The $829 Micro 510 adds the hard case and AirMist starter components and has a 3-year device warranty. Their listed dimensions match; their exact weights differ slightly. For $60 more, the 510 is the better buy if you want those included extras and the longer device warranty. Compare the exact seller's box contents and returns.

ResMed AirMini: best if you wear a ResMed F20 or N20

The AirMini is 5.4 x 3.3 x 2.1 inches and weighs 10.6 oz, machine only. Source: ResMed (opens in a new tab)

Why it's on the list

• ResMed names the exact masks and humidity cartridges that work with it. If yours is on the list, there is little guessing.
• It has three modes: CPAP, AutoSet and AutoSet for Her. Your prescriber picks the mode, not you.

What to know before you buy

• The $919 box has no hose and no mask. You need the correct compatible mask, tube and connector; buy the missing parts if you do not already own them.
• ResMed supports the mask setups listed above.
• With an F30 mask there is no waterless humidity.
• ResMed says the AirMini has no battery and "must be plugged into power." ResMed sells a converter for a car's 12V or 24V socket. Batteries come from other companies.
• It uses its own AirMini app, not myAir. Don't assume travel nights will show up in the app for your home machine. If your insurer or employer needs usage reports, ResMed says to ask your equipment provider how to get them. Source: ResMed app guidance (opens in a new tab)
• ResMed's own UK shop notes the AirMini is louder than its home devices. That is ResMed's comparison, not a sound test we performed. Source: ResMed UK shop (opens in a new tab)

Luna TravelPAP: a standard-mask backup choice

React Health's Luna TravelPAP (model LT2000) is 6.26 x 2.60 x 2.83 inches and weighs about 14.1 oz, device only. Its manual names BMC Medical Co., Ltd. as the manufacturer. Sources: React Health (opens in a new tab), Luna user manual (opens in a new tab)

Why it's on the list

• It takes standard masks and standard slim tubing.
• It runs in CPAP or auto-CPAP mode. If you've seen it described as fixed-pressure only, React Health's spec sheet lists both modes.
• It has exhale relief (React Health calls it RESlex), which eases pressure when you breathe out.
• React Health sells a 12V adapter for a car, truck or RV.

What to know before you buy

• It has no built-in humidifier. React Health's own comparison chart lists humidity as not available. We did not establish a maker-supported add-on HME setup. Source: React Health chart (opens in a new tab)
• It is the heaviest of the three.
• At $825, it is only $4 less than the Micro 510, which is smaller and includes humidity. Luna makes sense when you find it for less, or when you want to buy from a seller you already use.
• Its app is LightTrip (US). React Health describes provider reporting through React Health Connect; arrange the process before relying on it for compliance records. Source: TravelPAP FAQ (opens in a new tab)

Do you need a travel CPAP, or should you pack your home machine?

A travel CPAP is a convenience. For many people it is not a need.

One fact makes the home machine easier to bring. Under the applicable U.S. rules, airlines must not count an assistive device, like a CPAP, toward your carry-on limit, provided it can be stowed consistently with safety requirements. There is a catch. If the same bag also holds personal items, the airline can count it. So give the CPAP its own bag. Sources: 14 CFR 382.121 (opens in a new tab), DOT pamphlet (opens in a new tab)

Can a travel CPAP be your only machine? A travel label does not rule it out. Transcend says the Micro 510 is strong enough for full-time home use. ResMed says the AirMini meets the everyday needs of many users. The real questions are comfort, humidity and usage reports. Ask your prescriber before you make one your only machine.

Shopping for a full-size machine instead?

Humidity without a water tank

Your home machine likely warms a tank of water. Travel machines skip the tank.

AirMini and Micro 510 instead offer a heat and moisture exchanger, or HME. It is a small insert in the supported mask-and-hose assembly. It catches the moisture in the breath you blow out and gives it back on your next breath in. It adds no new water.

Waterless humidity can feel different from your heated humidifier. The mask layout and conditions affect how well it works for you. Try the complete prescribed setup before your trip, which is one more reason to check return terms.

The 30 days start when you open an individual HumidX cartridge, not when you first use it. Open one for a three-night trip, and it is past its date when you travel again six weeks later. At these pack prices, a replacement costs $12.33 for Standard or Plus ($37 / 3), or $14.67 for F20 ($44 / 3), before tax and shipping. Included starter cartridges reduce your first purchase; a trip longer than the 30-day limit needs another cartridge. Do not wash HumidX. Sources: cartridge prices (opens in a new tab), HumidX F20 guide (opens in a new tab)

AirMist has conflicting public instructions. The Micro 510 manual says 3–7 days of use, while Transcend's FAQ says 3–7 days after opening and its refill page says 5–7 days after opening. Follow the instructions supplied with your cartridge and ask Transcend if the timing is unclear. Do not assume a partly used cartridge can be stored until a much later trip. Sources: Micro 510 manual (opens in a new tab), Transcend FAQ (opens in a new tab), AirMist four-pack (opens in a new tab)

Luna has no built-in humidifier; React Health's comparison chart lists humidification as unavailable.

How loud are travel CPAP machines?

We can't name a quietest one, and you should doubt any page that does without testing.

dBA is a measure of sound level. These specifications do not establish which complete mask-and-machine setup will sound quietest to you. The test methods and configurations differ. Sources: AirMini guide (opens in a new tab), Micro 510 manual (opens in a new tab), Luna manual (opens in a new tab)

What you hear in bed also depends on your mask, your hose and any leaks. A device specification is not a measurement of your full setup at the pillow.

If noise could be a deal-breaker, buy from a seller that takes opened machines back, and try the full setup at home for a week before your trip.

Batteries and power

None of these three machines has a battery inside. A USB socket alone does not establish compatibility. Use a battery and cable arrangement documented for your exact CPAP model.

Wh means watt-hours: the battery's rated energy capacity, not the number of nights it will last. These totals use machine and battery offers from different sellers, so shipping and returns are separate. The Micro kit is also $829 direct from Transcend if you want both its machine and battery from one store. The Pilot-24 listing (opens in a new tab) says returns are for warranty problems only.

How many nights will it last? We won't guess. Transcend advertises up to 17.5 hours for PowerAway, with actual runtime varying by pressure settings, mask type, altitude, leaks and other factors. Charge the battery and test your prescribed setup at home before you count on it away from power. That is a manufacturer claim, not a runtime we measured. Source: PowerAway (opens in a new tab)

Are the cables and charger included?

• PowerAway: uses the Micro's included AC supply to recharge; there is no extra power supply in the battery box. Transcend states recharge takes under four hours.
• Pilot-24 Lite for AirMini: the $339 listing includes the AirMini output cable and short charging adapter. Medistrom says charging with the AirMini supply takes about 7–9 hours. Continuous backup needs an additional compatible AC supply; our total is for standalone travel use.
• Pilot-19 Lite for Luna: the $339 listing includes the Luna TravelPAP output cable and charging adapter cable. It charges with the Luna's existing AC supply in about 4–5 hours.

Sources: PowerAway (opens in a new tab), Medistrom Pilot-24 instructions (opens in a new tab), Pilot-24 offer (opens in a new tab), React Health's named battery kit (opens in a new tab), Pilot-19 offer (opens in a new tab).

Other power facts

• Other countries: all three listed AC supplies accept 100–240 volts, 50/60 Hz. Use the supplied or approved power supply and the correct plug adapter for the destination socket. Within that input range, a voltage converter is not needed.
• Car, truck or RV: ResMed sells a 12V/24V converter for the AirMini. React Health sells a 12V adapter for the Luna. A converter is not a battery. The AirMini DC converter's guide excludes aircraft use. Source: ResMed converter guide (opens in a new tab)
• High places: the manuals list operating limits of about 8,500 feet for AirMini, 8,000 feet for Micro 510 and 2,300 m (about 7,500 feet) for Luna. Check this before a mountain trip. These are operating-environment limits, not an aircraft's cruising altitude.

Flying with a CPAP

People ask "Is it FAA approved?" That is really four questions.

1. Can I bring it? Yes. Under the applicable U.S. rules, a CPAP in a bag used only for medical equipment does not count toward your carry-on limit, subject to safe stowage. Keeping it in the cabin also keeps it with you if checked luggage is delayed.

2. What happens at security? TSA's item page, updated July 15, 2026, says the machine, mask and tubing can stay in the carrying case for X-ray, but standard-screening passengers may have to take the case out of their carry-on. PreCheck passengers may leave it in both. A separate TSA FAQ still says to take the machine out of its case. Be ready for either. The officer decides. You can bring a clear plastic bag to set the machine in. Sources: TSA item page (opens in a new tab), TSA FAQ (opens in a new tab)

3. Can I use it during the flight? For aircraft designed for more than 19 passengers, the applicable U.S. rule generally requires covered airlines to allow a properly labeled CPAP that meets the device, stowage and safety requirements. Foreign-carrier requirements can differ. All three makers document aircraft compliance, but that does not replace the operating airline's process.

The airline can require 48 hours' notice and check-in up to one hour before its usual deadline. It can also require battery capacity for at least 150% of each segment's expected maximum flight duration. If the carrier gives you eight hours, 8 x 1.5 = 12 hours of required battery capability. That is not evidence that one of the batteries above will last twelve hours. Seat power is not promised. Contact the operating airline. Sources: 14 CFR 382.27 (opens in a new tab), 14 CFR 382.133 (opens in a new tab)

Prepare the settings before the flight and follow the device's inflight instructions. The AirMini and Luna manuals say to disable Bluetooth, avoid their apps during the flight, and use the machine's physical start/stop control. Sources: AirMini guide (opens in a new tab), Luna guide (opens in a new tab), Transcend's Micro 510 aircraft-compliance letter (opens in a new tab)

4. Can I bring the battery? Spare lithium batteries go in your carry-on, never in a checked bag; remove them if the bag is gate-checked and protect the terminals from short circuits. Up to 100 Wh is within the usual lithium-ion size limit. Above 100 through 160 Wh needs the airline's OK, with a limit of two larger spares. All three batteries above are under 100 Wh. Airlines can set stricter rules. Source: FAA PackSafe (opens in a new tab)

Before you leave

1. Get your prescription to the seller early and confirm its verification and shipping timeline.
2. Set up the whole travel kit at home and sleep with it for a few nights.
3. Pack the mask, hose, power supply, plug adapter and fresh humidity cartridges.
4. If you'll use it in flight, contact the operating airline at least 48 hours ahead and confirm its notice and early check-in requirements.
5. Charge the battery. Know its Wh number. It is printed on the battery.
6. Carry the device documents the airline requests and a copy of your prescription if useful for travel or replacement equipment. Transcend posts its aircraft-compliance letter on the product page.
7. Save the seller's support number in your phone.

Prescription, insurance and usage records

Prescription. Travel CPAPs need a prescription in the U.S., like any CPAP. Source: FDA (opens in a new tab) If you already use CPAP, ask your doctor's office for a copy of your current prescription. The seller checks that it matches the machine and tells you whether updated paperwork is needed.

Insurance. The prices here are cash prices. Medicare Part B may cover prescribed home CPAP when its medical and supplier requirements are met. For a covered machine, it pays rental for 13 continuous months of use before ownership transfers; deductible and cost-sharing rules still apply. That does not establish coverage for a second travel machine. Source: Medicare (opens in a new tab) ResMed says AirMini coverage "varies by insurance provider and plan." Transcend says it does not bill insurance but can provide reimbursement paperwork. Call your plan before you count on repayment.

HSA and FSA. Many sellers take these cards. Whether your plan allows it is up to your plan. ResMed says to check with your benefits administrator.

Usage records. If someone checks your CPAP use, ask how travel nights will be reported. Each machine has its own app.

Why the Z2 Auto and DreamStation Go aren't here

We left these out because their makers ended the product line or U.S. sales.

• Breas Z2 Auto (and Z1). Breas ended the Z Sleep Travel CPAP line on November 30, 2025. Its notice says service parts and patient accessories remain available through October 2030, with warranty/service terms unchanged; its FAQ says Nitelog remains supported. Discontinuation alone is not an instruction to stop prescribed therapy. Sources: Breas product notice (opens in a new tab), owner support (opens in a new tab)
• Philips DreamStation Go. Philips' U.S. notice lists January 25, 2024 as the end of sales and shipments, and January 25, 2029 as the stated end of service, subject to parts availability. Recall status is a separate device-specific question. If you own one, see Philips' notice (opens in a new tab) and the FDA's recall page (opens in a new tab), and talk to your supplier.

Travel CPAP questions

Is a tiny "micro CPAP" that sits in your nose the same thing?

No. The Transcend Micro 510 is a real CPAP with a blower, a hose and a mask, sold by prescription. The hoseless gadgets sold online under similar names are different products. Don't swap your prescribed CPAP for one without asking your prescriber.

Can I use my heated hose from home?

Don't count on it. The AirMini and Micro 510 use their own hose connections at the machine. The Luna uses standard unheated tubing.

Can I rent a travel CPAP before buying?

Ask your equipment supplier about a current prescription-based rental and its terms. We did not verify a specific rental offer, so we don't list one. Otherwise, the closest thing to a trial is a seller that takes opened machines back, with its fees and accessory exclusions.

What is the smallest travel CPAP?

Of the models compared here, the Micro 510 is the smallest: 3.6 x 3.6 x 2.4 inches and under 0.5 lb. The original Micro has the same listed dimensions but a slightly different weight. The AirMini is 10.6 oz and Luna about 14.1 oz. These are machine-only figures; your hose, mask, power supply, case and any battery add to what you carry.

How we compared these machines

We read each maker's product page and documents for size, modes, mask fit and humidity. We read seller listings for prices, box contents and return rules. We added up the totals ourselves and show the math. Everything was checked on October 7, 2026.

We did not buy or test these machines. No clinician reviewed this page. We selected three current U.S. travel CPAP/APAP models with maker documentation and verifiable seller offers, then compared mask fit, humidity, complete purchase cost, power and returns. This is a selected comparison, not a complete market inventory. Our "best for" labels come from the fit and cost facts above, not from a score.

Where a seller says something the maker does not, we say who said it. Prices change. Confirm the price and terms on the seller's page before you pay.
