One of the most common methods of treating obstructive sleep apnea (OSA) is the use of a CPAP machine. People with OSA have trouble breathing for brief periods of time throughout the night because their airway becomes blocked or collapses. Continual positive airway pressure (CPAP) machines are used to treat this condition by delivering a constant stream of pressurized air through a sealed mask, thereby restoring normal airflow and awakening the patient.

How to Clean a CPAP Machine

Keep your CPAP clean to keep it running smoothly and efficiently. Watch the video below, and we’ll show you how to clean your CPAP machine properly.

How to Choose a CPAP Machine

The CPAP machine is a highly effective treatment for OSA, but due to its complexity, it can be a stressful purchase. We’ve compiled a detailed how-to guide to assist our readers through this process. Read on to learn more about CPAP machines and the features to look for before making a purchase.

What to Consider When Purchasing a CPAP Machine

Ten main categories distinguish one CPAP machine from another; these should be considered alongside your doctor’s advice and recommendations. Each person has different requirements and preferences when it comes to a CPAP machine, so it’s important to take those into account as you go through the following checklist.

Doctor’s Recommendations

Your doctor may advise you on the best CPAP machine to use based on your unique case of sleep apnea and other factors. They may suggest a certain make and model, or offer guidance on the best machine for your needs in terms of pressure range, data tracking, and so on. It is best to consult your doctor if you have any doubts or questions before making a purchase that goes against their recommendations.

Machine Type

Positive airway pressure (PAP) machines come in a few different flavors, the most popular of which is the continuous positive airway pressure (CPAP) machine. BiPAP (bi-level positive airway pressure) machines vary the pressure between inhale and exhale, while APAP (automatic positive airway pressure) machines automatically adjust to your body’s needs from breath to breath. In most cases, CPAP machines are the best option, but your doctor or specialist should help you find the right one for you.

Climate Control

At the best of times, very few people look forward to breathing cold, dry air, which is why CPAP climate control is such a sought-after feature. Humidifiers, either built into the machine or added later, add moisture to the pressurized air, and heated tubing keeps the air at a pleasant temperature. However, humidifiers and heated tubing are not universally compatible with machines.

Pressure Range

Choosing the appropriate pressure setting for your CPAP machine is essential to ensure that the pressurized air it produces is effective in opening your airway without causing discomfort. The average user needs 10 cm H2O (a measure of air pressure) from their CPAP machine, but the range is typically 4–20 cm H2O. If your needs are greater than 20 cm H2O, your doctor or specialist will likely recommend a more powerful device that can provide 25 to 30 cm H2O.

Ramp Options

Though it helps many people get a good night’s sleep, CPAP machines can be irritating to some people. Reduced discomfort is achieved through ramp features, which gradually increase air pressure until the user is asleep. This feature is available on the vast majority of CPAP machines on the market today.

Sound Level

The average noise level of a modern CPAP machine is 30 dB, which is about the same as the sound of rustling leaves. Nonetheless, this may still be too loud for those with sensitive hearing or who sleep with a roommate. Whisper-quiet models, which operate at around 25 dB, may be more tolerable to those who live nearby.

Data Tracking

Smart features, available on many modern CPAP machines, allow you to keep track of your sleep and machine usage. You and your healthcare team can use this information to verify the treatment’s efficacy and you can give it to your insurer if they request it to cover the cost of your care. The most convenient way to keep track of information is with Wi-Fi-enabled machines that also work with smartphones, but you can also buy separate data-tracking accessories.


There are a wide variety of add-ons available for CPAP machines. Most include either a disposable or a reusable air filter, and some even have specialized add-ons like detachable humidifiers, cigarette lighter adapters, and rechargeable batteries. Make sure the machine has all the necessary add-ons, or is compatible with them, before you buy it.

Unique Features

There are a wide variety of CPAP machines on the market, and each has its own set of distinguishing features that may enhance your overall experience but are ultimately less important. Most of these functions are activated by the user, such as when they breathe into the mask to automatically turn on the device or when they exhale to lower the pressure. Ease-of-use settings are also available, such as having the screen’s brightness adapt to the lighting in the room.


Prices for CPAP machines typically run between $350 and $1,000, though more expensive models with additional features or for medical use can go as high as $3,000. You shouldn’t just go for the cheapest option; instead, you should consider your needs and the machine’s performance.


Most CPAP machines have guarantees attached to them. Warranties typically last for 2 years, but you can find companies that provide 3, 4, or even 5 years. It’s not just the length of the warranty that’s important to consider; the terms of the warranty as well. Some companies make customers ship back their broken product before replacing it, leaving them without a machine in the meantime.

How to Buy a CPAP Machine

A CPAP machine is unlike anything you have ever purchased or set up before. To begin, before making a sale, vendors will ask for a doctor’s or specialist’s prescription. After making the initial investment in your machine, you’ll have to do things like adjust the pressure settings, buy and install any necessary extras, and maybe even negotiate reimbursement terms with your insurance company.

Prescription Required

A CPAP machine is a medical device that requires a prescription from your primary care physician or a sleep physician. If you prefer to buy your CPAP machine from a brick-and-mortar shop, the sales staff will accept your prescription just as a pharmacist would. Online purchases are only marginally more complicated than in-store purchases because most vendors require a prescription upload before a sale can be finalized. This can be done at many stores online or by fax. Online shopping is preferable because of the greater variety and lower prices.

Doctor’s Recommendations

Maintain the treatment plan prescribed by your doctor for sleep apnea just as you would for any other medical condition. However, your doctor may recommend a BiPAP or APAP machine instead of a CPAP if your condition calls for it. It is essential to make sure you buy a machine that can operate in a pressure range above 20 cm H2O if your doctor has recommended this.

Health Insurance

Unfortunately, CPAP machines aren’t covered by all medical plans. If yours does, you can find details about your plan’s coverage for durable medical equipment under the “benefits” heading. Because of the complexities of CPAP insurance, most companies require their customers to “rent” the device rather than “buy,” with monthly payments applied to the customer’s share of the total cost. Your insurance company may also want to see your usage records to make sure you’re getting the most out of your machine. It may be more convenient and economical to pay cash for your machine instead of using your insurance to make the purchase. Investigating your policy is essential for figuring out your options and making the most of your coverage.


While using a CPAP machine, you may find that you need a few of the many available accessories. Since masks and headgear are not included with most CPAP machines, you will need to buy them separately. They can be purchased for as little as $30 and as much as $150, with many customers trying out multiple models before settling on the best one for them. A mask should be replaced every three to six months at the very least. Sleep accessories like specialized pillows and machine add-ons like external humidifiers and data collection systems are also available.

Where to Buy

After receiving a CPAP prescription, you can go to any one of several different retailers to pick up your new device. Best prices and selection can be found at retailers, whether they are traditional stores or found solely online. Additionally, CPAP machines may be available for purchase from your doctor or sleep specialist, allowing you to purchase your equipment directly from them. Last but not least, some sleep centers let patients rent CPAP machines if they’d like to test one out before buying it or if they simply can’t afford to buy one right away.

What Types of Sleep Apnea Machines Are There?

There are a few different kinds of positive airway pressure (PAP) machines used to treat sleep apnea, but the term “CPAP machine” is often used interchangeably for all of them. Automatic positive airway pressure (APAP) and bi-level positive airway pressure (BiPAP) machines are the other two types of PAP machines. It is essential that you adhere to your doctor’s recommendations regarding the type of PAP machine that is best suited to you and your individual health needs. CPAP: Throughout the night, a single, tunable amount of air pressure is delivered by a CPAP machine. This is an excellent treatment for obstructive sleep apnea because it maintains an open airway during inhalation and exhalation. Since CPAP doesn’t call for pressure sensors, it’s also the most budget-friendly PAP treatment option. But for some, the constant pressure, especially on exhalation, can be intolerable. Most CPAP users get used to this sensation after some time, or by adjusting their pressure settings as their doctor advises, but some may need to upgrade to an APAP or BiPAP machine. Bi-level positive airway pressure (BiPAP) machines have two settings: inhalation pressure (also known as IPAP) and expiration pressure (also known as EPAP). The air pressure ranges of these machines are typically higher, sitting anywhere from 4 to 25 cm H2O. BiPAP machines are used by people who suffer from sleep apnea and need structured airway support but cannot use CPAP machines. Patients with conditions such as chronic obstructive pulmonary disease, heart failure, Parkinson’s, and amyotrophic lateral sclerosis make up this latter group. There are some drawbacks to using a BiPAP machine, such as the higher cost, the requirement to first use CPAP, and the possibility that OSA patients will develop central sleep apnea (CSA). At any time during the night, an APAP machine’s sensors will readjust the pressure to meet the needs of the user, thanks to technology called automatic positive airway pressure (APAP). Sleep position, sleep stage, and the use of sedative medications are just a few of the many potential variables that can affect these requirements. By monitoring the user’s breath resistance throughout each breathing cycle, the device can reduce pressure during times of relative ease and increase it during times of potential difficulty breathing. Although many people benefit from the use of APAP machines, their high price and ineffectiveness for some patients with heart or breathing conditions make them less accessible. Automatic adjustments can be more annoying to some people than the constant pressure of a CPAP machine. CPAP machines designed specifically for use while traveling have all the same capabilities as regular CPAP machines, plus some extras that make them more convenient to use while away from home. They are lightweight and compact, making them ideal for taking along on trips or camping trips; they can also be used after dark by charging the battery they come with. Accessories for use on a plane must be certified by the Federal Aviation Administration.

How to Choose and Use a CPAP Machine for Sleep Apnea

Having trouble coping with the demands of therapy? Your journey can be made easier with the help of our guide, allowing you to get a more restful night’s sleep. You may have been prescribed continuous positive airway pressure by your doctor if you have been diagnosed with obstructive sleep apnea (OSA), which results in frequent, brief pauses in breathing during sleep. The most common method of treating this condition involves wearing a mask-like device that is linked to a pump. While you sleep, the airway is kept open by the pump’s pressure. If you use a CPAP machine at night, you can drastically reduce the number of times your breathing stops during the night. Moreover, a 2016 review of studies published in the Journal of Otolaryngology – Head and Neck Surgery found that about one-third of CPAP users don’t continue treatment as intended. The review found that user complaints about CPAP’s discomfort, inconvenience, and claustrophobia were common. It can be difficult to participate in the therapy. Mequon, Wisconsin resident David Levey, age 60, found using CPAP to be a nuisance when he first started using it about 15 years ago. “I was a side sleeper, and the pillow would knock the mask out of place,” Levey says. So instead of getting a good night’s rest, he kept waking up with the device’s air blowing directly into his eyes. However, sleep apnea needs to be managed. Dr. Raj Dasgupta, a pulmonary and sleep medicine specialist at Keck Medicine of USC in Los Angeles, says untreated cases can lead to excessive daytime sleepiness. In turn, this can cause you to nod off in embarrassing situations like the middle of a meal, behind the wheel, or in the middle of a conversation. There may be risks involved. In fact, the risk of being involved in a car accident is increased by 50 percent if sleep apnea is left untreated, according to a Swedish study published in the journal Sleep in 2015. The National Transportation Safety Board also speculates that untreated sleep apnea contributed to two commuter-train accidents that resulted in over 200 injuries and one fatality between 2016 and 2017 (one in Hoboken, NJ, and the other in Brooklyn, NY). Sleep apnea has been linked to an increased risk of high blood pressure, arrhythmias, heart failure, and stroke when left untreated. People with sleep apnea often wonder if they will die if they don’t get treatment. According to Dasgupta, “yes” is the shortest possible explanation. Irrespective of how long you’ve been using CPAP or how much success you’ve had with it, here are some tips for optimizing your treatment.

How CPAP Works

The American Academy of Sleep Medicine estimates that 5.9 million adults in the United States have been diagnosed with OSA. The disorder is characterized by a collapse of the soft tissue at the back of the throat during sleep, which prevents adequate airflow to the lungs. As a result, breathing stops frequently throughout the night, sometimes hundreds of times. Since the 1980s, patients with moderate to severe OSA have relied on continuous positive airway pressure (CPAP) therapy, which forces enough air into the upper airway to keep it open. It has been shown that the prescription treatment can help people get a better night’s sleep, feel more alert during the day, return their blood pressure to normal, and reduce other health risks associated with insufficient sleep. For instance, a 2018 study of over 40,000 Danish adults with sleep apnea published in the Journal of the American Heart Association found that non-CPAP users had a 38% higher risk of heart failure than CPAP users. The effectiveness of CPAP is matched by the fact that modern machines are less obtrusive and noisier than their predecessors. Many modern CPAP machines have a feature that lets you start the night with a lower air pressure setting and gradually increase it as you sleep. This may make breathing in through your mouth or nose less of a shock. Nightly breathing patterns can be detected by some CPAP machines, and the machine will automatically adjust the air pressure to meet your needs.

Find the Right Device for You

Finding a CPAP mask that fits well and is comfortable enough to sleep in is crucial. (You should also think about the severity of your OSA and the air pressure setting your doctor has suggested to keep your airways open while you sleep.) However, this may take a while. According to Steven Feinsilver, M.D., director of sleep medicine at Lenox Hill Hospital in New York City, utilizing a CPAP machine can still feel cumbersome and unnatural. As a general rule, people don’t end up liking the first gadget they try. It may take a few tries for some people to find the one that works best for them, he says. Hb Alumisin, 33, of New York City tried two different masks for his mild sleep apnea before deciding on nasal pillows (see below). The masks were too bulky for him to sleep in, but the pillows are soft and unobtrusive. Where do we go from here? You should “try masks on with the doctor-recommended air pressure settings you’ll be using to see what it really feels like when the machine is on,” as Dasgupta recommends during your fitting (which can be done at home or at a sleep center). Also, as Dasgupta points out, you don’t want to squeeze your face so much that the device you’re considering doesn’t form a seal where it needs to, but you also don’t want it to be too loose. Learn the distinctions between the three standard CPAP masks: Pillows for the nose. Small plastic plugs called “pillows” are placed directly below the nostrils to help channel air into the nose. Nasal pillows are the most compact and light-weight choice, and they can be used with only a small amount of contact to the face. According to the American Academy of Sleep Technologists (AAST), pillows are ideal for those who need a low to moderate air pressure setting, as well as for those who have a lot of facial hair or who feel claustrophobic wearing a larger mask. However, the fact that air is being forced directly into the nostrils, particularly at higher pressure settings, can lead to some discomfort and irritation. Users have complained of nosebleeds and dry noses. Because it only directs pressurized air through the nasal passages, this mask may not be as effective for people who typically breathe through their mouths. Inhalant mask. If you wear this mask, it will cover your nose and upper lip but leave your mouth exposed. When compared to nasal pillows, nasal masks provide a more natural sensation of airflow, so the AAST recommends them. As opposed to using pillows, some people find that breathing through a mask is more comfortable because the air is less dense. Edwin Valladares, a CPAP user and the manager of the Sleep Disorders Center at Keck Medicine of USC, says that the device may be more comfortable if it were spread out over a larger area. A deviated septum, severe allergies, or blocked sinuses could make it difficult for someone wearing a nasal mask to breathe normally through their nose. The mask can be irritating to the bridge of the nose in some people. Wraparound mask. This mask fits snugly over the nose and mouth to prevent air from escaping through either opening. People who have trouble breathing through their nose while sleeping due to allergies or medical conditions may benefit from using a full face mask. According to the AAST, it may also be effective for people who require a higher pressure setting but find this method more tolerable than a nasal mask. But the weight and size could be an issue for some consumers.

Then, Ease Your Way In

Rowley estimates that using CPAP at night might take two to three weeks before you get used to it, and another four to six weeks before you start to notice any real improvement. Many people respond best to CPAP when it is introduced gradually, according to Feinsilver. Put in a minimum of 20-30 minutes of CPAP time before bed. Put the mask on, power up the machine, and relax with some mindless entertainment. Once you’ve gotten used to the gadget, try sleeping with it. If you don’t go to sleep within an hour, Feinsilver advises taking a break and giving it another shot the next day. You should talk to your sleep medicine specialist or the company that supplied your medical equipment if the mask you were fitted for becomes uncomfortable or difficult to adjust after a few nights of use. You could use some mask-related assistance, possibly including some adjustments or a switch to a different design.

Deal With Dry Mouth and Nasal Stuffiness

How to respond to other frequent CPAP-related complaints is outlined below. Lack of saliva in the mouth According to James Rowley, M.D., medical director of the Sleep Disorders Center at Detroit Receiving Hospital, dry mouth can occur when a full mask fails to form a tight seal over your face or when using a nasal mask or nasal pillows if you’re mouth-breathing. The Proper Course of Action: Your sleep medicine doctor or sleep technician should examine the fit of your full mask if you use one. If you sleep with your mouth open and need a device to keep it closed while you sleep, ask your provider if a chin strap can be attached to your nasal mask or nasal pillow. Tightness in the Nose A direct stream of air to the nasal cavity can cause this. The solution is to use the humidifier that is included in most modern CPAP machines; this may help alleviate nasal congestion. And if that doesn’t work, Rowley advises seeing a doctor. In most cases, he says, an antihistamine or nasal steroid spray will do the trick for clearing up congestion caused by CPAP. Rash At the point where the mask makes contact with the skin, some CPAP users experience redness, itching, and even a rash. The AAST reports that allergic reactions to CPAP masks are uncommon and that skin issues are typically the result of improper mask hygiene. How to Proceed: Rowley recommends weekly washes of the mask and humidifier chamber with soap and water. (Find additional information about CPAP maintenance here.) Some studies have failed to find a connection between CPAP use and an increased risk of respiratory infections like pneumonia. Problems Persisting? Stay Strong! Even if you feel that CPAP isn’t helping you after two or three weeks of trying it, Rowley advises that you not give up on it before discussing other options with your sleep doctor. As a result, some people may need more time to readjust. According to David Levey, who switched from a side sleeping position to a back position to prevent his CPAP from slipping out of place, it took him two to three months to feel completely at ease with his CPAP. ‘The hardest part of adjusting to CPAP was learning to sleep on my back, but once I did, I woke up feeling so much more refreshed,’ he says. In addition to continuous positive airway pressure (CPAP), there are other options, such as mouth guards (mandibular advancement devices) and surgically implanted devices that deliver electrical impulses to the nerve that controls the upper airway muscles, to keep the airway open. The severity of sleep apnea can be lessened by losing weight if you are overweight. And remember this: “Not only will addressing your sleep apnea help you sleep better, but you might live longer,” Feinsilver says.
