Positive airway pressure (PAP) therapy uses pressurized air delivered through a hose and a mask to promote more consistent breathing during sleep. While continuous positive airway pressure (CPAP) devices are more frequently used to treat obstructive sleep apnea, for some people a bilevel positive airway pressure (BiPAP or BPAP) machine can provide unique benefits.

While CPAP machines operate at one fixed air pressure level, BiPAP devices feature a higher pressure setting for inhalation and lower pressure when exhaling.   

We’ll provide our picks for the best BiPAP machines, discuss who may be a good candidate for a bilevel device, and share key background information that can help you choose the optimal therapy device for your needs.

How We Make Our Picks

Our picks are designed to help you by simplifying the process of finding a BiPAP machine, which can often feel technical and confusing. Our team of sleep health experts has a deep understanding of sleep apnea, how PAP therapy works, and what features can contribute to successful PAP-based treatment. When choosing the best BiPAP machines, we analyzed factors like brand reputation, device features and track record, customer reviews, and product availability.

What is a BiPAP Machine?

A BiPAP machine is a medical device that sends pressurized air into the upper airway through a hose and a mask in order to stabilize breathing and treat sleep apnea and other sleep-related breathing disorders. A defining feature of a BiPAP device is its ability to deliver different levels of air pressure when inhaling and exhaling.

Most BiPAP machines come with tubing, a power supply and power cord, and an air filter. Some BiPAP devices include a built-in humidifier with a removable water chamber, though humidifiers are also available individually.

Masks are typically sold separately. Products marketed as CPAP masks are generally compatible with other types of PAP machines.

Using BiPAP Therapy for Sleep Apnea

Sleep apnea is a condition that causes brief interruptions to breathing as a person sleeps. People with sleep apnea often experience poor sleep and may have other health complications linked to repeated breathing disruptions. 

To use a BiPAP machine, you wear a mask that is attached to the device by a hose. Pressurized air is sent through the tubing and into your upper airway, which helps prevent breathing interruptions during sleep. The main feature that distinguishes a BiPAP machine from other types of PAP machines is that it has separate pressure settings for when you breathe in and breathe out. 

BiPAP therapy may be recommended to treat different types of sleep apnea, including obstructive sleep apnea, central sleep apnea, and complex sleep apnea. 

  • Obstructive sleep apnea (OSA): Obstructive sleep apnea occurs when the airway becomes temporarily blocked during sleep. The stream of air from a PAP machine can help prevent the airway from becoming obstructed. Some people find PAP therapy to be more comfortable with the variable pressure of a BiPAP device.
  • Central sleep apnea (CSA): Central sleep apnea occurs when the brain’s process of controlling breathing becomes disrupted. For some people with CSA, a BiPAP machine can support a more stable and consistent breathing pattern. Some people with CSA experience Cheyne-Stokes respirations, a condition characterized by an alternating pattern of shallow breathing and hyperventilation.
  • Complex sleep apnea: Referred to as treatment-emergent central sleep apnea by medical experts, this is a type of CSA that can arise in people with OSA undergoing PAP therapy. A BiPAP device that includes a backup respiratory rate ensuring a minimum number of breaths per minute may be helpful in treating this type of sleep apnea.

While BiPAP therapy is a potential treatment option for these types of sleep apnea, it is often not the first type of therapy that is recommended. In many cases, a BiPAP machine is only prescribed after CPAP therapy has already been tried.

Types of BiPAP Machines for Sleep Apnea

While the common denominator of all BiPAP machines is the delivery of different air pressure levels for inhalation and exhalation, some models include algorithms that detect breathing patterns and make various adjustments in real time.

  • Fixed-pressure BiPAP: This type of BiPAP machine has fixed air pressure levels for when you breathe in and breathe out. These settings are determined during an overnight titration study where sleep technologists directly observe how well the machine is helping your breathing and adjust its settings accordingly. 
  • Auto-adjusting BiPAP: Some BiPAP devices are auto-adjusting, which means they use specially designed software to recognize breathing patterns and adjust the pressure levels in response. The initial settings for an auto-adjusting BiPAP machine are generally still determined during a lab-based titration study. 

Are There Travel BiPAP Machines?

While travel CPAP machines are common, there are fewer travel BiPAP machine options available. However, several manufacturers offer compact, lightweight BiPAP models that are better suited to being stowed away, taken on the road, and powered with an external battery.

What is the Difference Between BiPAP and CPAP Machines?

The main difference between BiPAP and CPAP machines is that CPAP machines have one pressure setting while BiPAP devices have a higher pressure setting for breathing in and a lower pressure level for breathing out.

BiPAP and CPAP machines are fairly similar in appearance, but their differing pressure settings can have significant impacts for treating sleep apnea and other breathing-related conditions. Make sure to discuss your symptoms and unique needs with your health care provider to determine the treatment that’s best for you.

How to Find the Best BiPAP Machine for You

To find the best BiPAP machine for you, it’s important to consider your priorities and needs for sleep apnea treatment. Before buying a new machine, think about your price range, how much space you have available, and what advanced features are most important to you.

BiPAP Machine Pricing and Sizing

BiPAP machines can vary widely in price, usually costing between $1,700 and $3,000. More expensive models typically offer more complex features. In general, BiPAP machines cost more than CPAP machines because they have a more diverse range of functions and pressure settings.  

Most BiPAP machines are rectangular and measure less than a foot long. Although they are larger than a standard alarm clock, BiPAP machines are normally small enough to fit on a nightstand or bedside table.

BiPAP Machine Pressure Ranges and Noise Levels

Pressure RangesMost BiPAP machines can provide pressure levels from 4 to 25 centimeters of water pressure (cm H2O), which is a common measure of air pressure for PAP devices. Some BiPAP devices max out at 30 cm H2O.
Sound LevelsModern BiPAP machines are relatively quiet when running. The quietest machines generate only 25 to 30 decibels, a sound level equivalent to a whisper.

BiPAP Data Tracking, Ramp Settings, and Smart Features

Data TrackingMany BiPAP machines can track and store key data, including how long you use your machine, sleep duration, pressure statistics, quality of mask seal, and sleep apnea events per hour.
Ramp SettingsA ramp setting starts the machine at a lower pressure and slowly increases the pressure level over a set period. Reduced pressure at the start of the night may make it easier to fall asleep.
Smart FeaturesSmart features include cellular connectivity, preheat settings for humidifiers, auto-adjusting screen brightness, and automatic start and stop sensors that detect when the user’s mask is in place.

BiPAP Programmable Modes

While the ability to switch between higher and lower pressure settings for inhalation and exhalation is standard for BiPAP machines, some devices include more advanced algorithms designed to meet specific breathing needs.

  • Spontaneous mode (S): In this mode, the BiPAP machine only uses the cues from a person’s breathing, such as changes in airflow, to adjust between the different pressure levels.
  • Timed mode (T): In timed mode, the BiPAP machine uses a fixed time period to cycle between the pressure level for breathing in and out. Unless a person struggles to breathe on their own, it is rare for timed mode to be used because it can create misalignment between the device’s airflow and a person’s actual breathing pattern. 
  • Spontaneous-timed mode (S/T): In this hybrid mode, the BiPAP machine uses cues from a person’s breathing to adjust the pressure, but there’s a fail-safe — often called a backup rate or backup breath — that increases the air pressure if the machine doesn’t detect that the user has inhaled within a set period of time. This mode is often used for people with irregular breathing patterns linked to central sleep apnea.

BiPAP Prescription, Insurance, and Purchasing Information

BiPAP machines are a form of medical equipment. This means there are some rules and regulations to navigate during the purchasing process.

Do You Need a Prescription for a BiPAP Machine?

The Food and Drug Administration classifies PAP machines, including BiPAP devices, as class II medical devices. While this designation ensures that BiPAP machines meet certain safety standards, it also means that a prescription is required.

Does Health Insurance Cover BiPAP Costs?

Health insurance coverage for BiPAP expenses can be less straightforward than CPAP therapy. Some providers may only cover a portion of BiPAP costs if a person’s apnea-hypopnea index (AHI) score — a measure of sleep apnea severity — exceeds a certain threshold. Additionally, some plans only provide BiPAP coverage if it has been demonstrated that a person has first unsuccessfully tried CPAP therapy.

Check with your insurance provider regarding your plan’s PAP therapy specifics and coverage requirements.

Where Can You Buy a BiPAP Machine?

BiPAP machines are available from online and brick-and-mortar medical equipment providers, as well as retailers that specialize in CPAP devices and accessories. Regardless of the buying method, you’ll need to provide a copy of your prescription before making a purchase. Online retailers often accept prescriptions via fax or email.

Buying a BiPAP machine in person lets you see the equipment and pose questions to sales staff. Online stores generally have a larger selection of machines and often have lower prices. Stores that offer CPAP and BiPAP machines typically sell other therapy accessories, including masks, tubing, filters, and optional supplies like CPAP batteries.

How Do You Clean a BiPAP Machine?

Because it delivers air for you to breathe, it’s important to keep your BiPAP machine clean. This helps prevent bacterial growth and can extend the life of your BiPAP device and components.

In general, BiPAP machine accessories should be cleaned with warm water and mild soap. While the following are general cleaning guidelines, refer to user manuals for specific manufacturer’s instructions regarding cleaning methods and frequencies. 

  • Machine: Unplug the device and wipe down the outside with a nonabrasive cloth about once per week.
  • Mask: Use mild soap and a damp cloth to gently clean your mask every day. Alternatively, specially designed CPAP wipes can be used for daily mask maintenance. Once a week, take your mask apart and wash all the components more thoroughly in warm water and a mild detergent. Allow everything to dry completely before reassembling the mask.
  • Headgear: Take apart the headgear and straps from your mask and hand-wash them once a week or anytime they appear dirty.
  • Tubing: Wash the hose thoroughly once a week and hang it up to fully dry.
  • Humidifier water chamber: Empty the water tank every morning and wash it roughly once per week. Only fill the chamber with distilled water, as other types of water can cause mineral buildup and could lead to the growth of potentially harmful bacteria
  • Filters: Follow the manufacturer’s recommended schedule for replacing your filter. If you have a reusable filter, wash it once a week and replace it according to the manufacturer’s suggested time frame.

Avoid using abrasive cleaners like rubbing alcohol or bleach that can damage your BiPAP machine and accessories. The FDA has cautioned against using ozone gas or ultraviolet light cleaners, as the agency hasn’t cleared or approved these products, nor has it made a determination regarding their safety and efficacy.
