Today's CPAP machines are small and portable and the vast majority are suited for travel. Travel friendly machines are small sized, but newer machines also offer on-the-go humidification and integrated or stand alone power options. All machines sold by CPAP.com support both US and International power outlets, although additional plug adapters are needed. This section will help you familiarize yourself with airline CPAP rules and CPAP user tips for successful travel.
All CPAP, APAP, and BiPAP machines can be used everyday. The newer machines that are smaller and lighter are still robust enough for constant daily use as well as travel.
CPAP therapy should be used every night. You CPAP should go with you on trips. There are some tips to help with your travel:
To prepare for your international travel, be sure to:
An adapter may be required to plug a US power cord into a wall outlet in a foreign country. CPAP.com sells an assortment pack of World Traveler Power Adapter Plugs, which allow CPAP machines to plug into different types of wall sockets found in different countries.
All the models CPAP.com sell contain power converters that enable the machine to operate on any AC current from 100 to 240 volts without any adjustment. Check with your dealer or manufacturer to see if your machine needs an external converter that lowers the voltage from 240 to 120 VAC.
Yes. CPAP therapy should be used every night. In the USA, CPAP it is not counted as a carry on item for air travel. Some locations in Asia and Europe will count it as a carry on, but all will allow it.
Air Travel: Call your airline. Each airline has a different policy on whether or not you can use your CPAP while in flight, and if they have a power source available.
We provide our customers with many tools to make informed decisions about their machine purchases. Options include:
We work very hard to provide many different ways for our customers to compare products. Here are the machine product guides we have created and maintain:
Wondering which filters work for your machine? Or trying to find the right replacement power cord? To find what parts are compatible with your machine or to find what parts of your machine are replaceable you can:
Machines come with a six foot hose, power cord, at least one filter, and manuals. Most manufacturers include a carrying case which is designed specifically for their equipment. CPAP / BiPAP / APAP machines do not come with a delivery system or mask. CPAP Masks must be purchased separately.
To see the list of what specifically comes with each machine, you can browse for a machine. Then on the product page, click the "Specs" tab to see a full list of what comes with the machine.
Yes, all CPAPs use at least one filter that is usually a type of foam material and washable. Some CPAPs offer finer filtration with the addition of a disposable paper filter.
Cleaning and changing filters is the only maintenance required for a CPAP machine.
The filters are located at the back of the machine at the air intake. The image below shows the black foam filter at the back of the Everest 3 CPAP Machine.
Washable foam filters should be cleaned as soon as they become discolored. Depending on your environment, that may mean weekly cleaning.
Disposable filters should not be cleaned, just disposed of.
The only care a CPAP or BiPAP machine requires is to clean or change the filters at the air intake. This keeps the internal parts from accumulating dust. Fine, paper filters should be changed out every 30 days, or when they appear soiled. Foam, washable filters should be rinsed with clear running water once a week, allowed to air dry, and reinserted.
There are some other suggested actions to care for your machine:
All CPAP masks work with all machines.
Many CPAPs operate on 12 volt DC power. If your CPAP has a DC outlet, a round, single hole in the back or side of the unit, then you should be able to operate it from a 12 volt DC power source. The appropriate DC power cord is needed but inverter is not necessary. Typically, the DC power cords plugs into the CPAP and end in a cigarette lighter plug. To connect a CPAP directly to a battery, you would need a DC adapter cable that fits over the cigarette lighter plug on the DC power cord and ends in alligator clips.
For the longest usage time, we suggest you use a deep-cycle marine type battery. It will operate most CPAPs at most pressures for about three nights before needing to be recharged. We sell a smaller, portable, rechargeable Battery Pack on our site that will operate most CPAPs and most pressures for one night. We also have battery kits that come with everything needed to run your machine off battery power including the right cables needed for your machine and a battery.
The Transcend II Travel CPAP Machine by Somnetics can be set up to have a fail-over, back up battery by using their Transcend Multi-Night Battery. If the power goes out, the machine will automatically switch over to battery power without an interruption to your CPAP therapy.Read about that on the "Power" tab of the Transcend Machine page.
Most CPAP and BiLevel machines today are designed to operate on both AC and DC battery currents. In the United States, the AC current from wall outlets is 110 volt and most batteries produce 12 volt DC current. Overseas, the AC current is usually 220 or 240 volt.
We include information about the power needs and capacities in the description of our products. Please see the "Power" tab on any machine product page for this information. You can also see a summary of the voltage range and whether it is DC capable on our Compare Charts.
All CPAPs will operate on DC power with the use of an inverter to change the current from DC to AC before it reaches the machine. However, many will operate on DC power without the need for an inverter, just a power cord that plugs into the CPAP and ends in a cigarette lighter plug.
Inverters do require a lot of power. If you need to use an inverter to run your machine on battery power, the inverter will probably take about half the life off the battery.
To determine if your CPAP will operate without an inverter, look for a DC outlet on the machine, either at the back or on the side, with a single opening directly in the center. It should be labeled "DC Power" or similar term. You can also review our Compare Charts to see if your machine has a optional DC cable option.
First you need to determine if your machine is configured to operate on DC power and has a DC power outlet. If your machine does have a DC power outlet and you want to run your marine battery, then you will need the correct DC cable for your machine and an adapter cable that fits over the cigarette lighter plug and ends in alligator clips.
CPAP.com sells complete battery kits with everything you need for your machine including the right cables for your machine and the battery. You can find the right battery kit for your machine here.
If your machine does not have a DC power outlet, then you will also need an inverter to be able to run your machine on battery power.
If you have questions about the specific power needs of your machine, review the "Power" tab on your machine's product page, or give us a call at 1-800-356-5221.
For longer battery use, we suggest a deep-cycle marine battery. A CPAP set at 10cm will usually run for about three nights before having to recharge a deep cycle marine battery. A car battery will usually run a machine for 8 hours and still start the car.
There are small, portable battery packs that will operate a CPAP set at 10cm for at least one night, or about eight hours. CPAP.com sells full battery kits that come with everything needed to run your machine off battery power including the right cables needed for your machine and a battery. You can find the battery kit for your machine here. On each battery kit page, you can input your machine and pressure setting to see an estimate battery life for your machine.
There are a lot of back up battery choices out there that can give you peace of mind in case of a power outage. The Transcend II Travel CPAP Machine has Batterie Options available for that can set up as a fail-over, back up battery. Review the "Power" Tab on the machine page.
CPAP.com sells battery packs to accompany your machine if an integrated battery is not available. Visit CPAPtalk for more advice specific to your needs, or view this past thread on the topic here.
Using a heated humidifier on a 12volt battery power source will significantly reduce the amount of power provided. In most cases, usage is reduced to less than half the estimated operational time. CPAPs or BiPAPs requiring inverters reduce the power time even more.
Please note that some heated humidifiers are not capable of being operated on 12volt battery power sources. The later M Series heated humidifiers with the 6'' 'pigtail' connectors are capable of running on 12volt DC power sources. Earlier model M Series heated humidifiers without the pigtail are not 12Volt capable, nor are the Legacy model REMstar and stand-alone H2 humidifiers.
For optimum performance of your battery, plan to use your CPAP without the heated humidifier. You may also have the humidifier connected and filled with water, but without the power turned on. This changes a typical heated humidifier into a passive humidifier.
We suggest testing the battery setup you are planning to use with your machine in advance. To determine the actual amount of power time you will receive and whether or not heated humidification is required for your comfort, test the battery at home before traveling.
When a physician orders a pressure change, or a patient moves to an area with a very different altitude and does not have an altitude compensating machine, there are a number of ways to ensure you are receiving CPAP therapy at the correct pressure.
Sleep laboratories and sleep disorder centers may be willing to make this pressure change. Just call a big local hospital or ask you physician for sleep lab phone numbers. Be sure to take your prescription.
A second way is to do it yourself. We sell manometers that are very portable, accurate, and simple to use. All the machines we sell come with instructions on how to set pressure to physician orders. Most patients have little trouble doing this themselves. If you need help we can talk you through the procedure.

A third option is to ship the machine to us with the new prescription. We will set it and ship it back.
It is the law and good common sense to run all sleep disorder devices at the prescribed pressure. If you think your prescribed pressure is wrong, talk to your physician.
CPAP machines which record full data (like AHI and leak info):
Bloating is a sign that you are swallowing the CPAP air. There is no real medical solution, but we have found that sleeping position may be a factor. Try sleeping as flat as possible first, even without a pillow. If that position doesn't help, try sleeping on your side or elevated, whichever one you don't sleep in now.
If changing your position doesn't resolve the problem, talk to your doctor about the possibility of lowering your pressure a bit. It may let a few apneas through, but the trade-off might be worth it.
Yes. Federal law requires we have a valid prescription on file before we ship your mask, machine and/or humidifier.
