At a Glance
Micro-CPAP devices are small, mask-free gadgets designed to sit inside the nostrils and use tiny pumps to create airflow that keeps the airway open. However, these devices are still in development and have not been proven to effectively treat sleep apnea, and there is currently no FDA-approved micro-CPAP available to replace traditional CPAP therapy.
For those with obstructive sleep apnea (OSA), CPAP therapy is the most effective and commonly prescribed treatment. However, some people find CPAP therapy uncomfortable or inconvenient, and in some cases, these issues cause them to stop treatment.
Micro-CPAP is a concept for a new device that aims to make OSA treatment simpler and more comfortable. Below, we’ll explore how this technology works, whether it’s effective, and when it could be available.

What Is a Micro-CPAP Device?
A micro-CPAP device aims to offer an alternative to CPAP therapy that’s small enough to fit in the palm of your hand. The user places it inside the nose, where silicone nose buds create a seal that allows the device to pump pressurized air into the airway.
Ideally, this pressurized air would help treat OSA, which occurs when airways become partially or completely blocked during sleep and leads to disturbances in airflow and sleep continuity. However, micro-CPAP technology is still in development and isn’t currently available for purchase.
How Would a Micro-CPAP Machine Work?
Micro-CPAP devices would operate by using hundreds of micro-blowers, which generate power using an electrostatic charge. The micro-blowers would open and close to create pressurized air, which would treat OSA by creating positive airway pressure. The device as conceived is battery-powered and is only meant for a single use, though a future design may involve a rechargeable battery.
Micro-CPAP devices are being developed to eliminate the need for larger CPAP machines and potentially uncomfortable face masks. Traditional CPAP machines are meant to be used nightly, with minimum compliance defined as at least four hours per night for at least five nights per week. However, anywhere from 30% to 80% of people don’t use their CPAP machines this often.
What’s the Difference Between Micro-CPAP and Standard CPAP?
While the name micro-CPAP suggests that the device is simply a smaller version of standard CPAP therapy, there are many crucial differences between traditional CPAP treatment and what we currently know about Micro-CPAP.
Note that micro-CPAP is a concept that hasn’t been FDA-approved or made available for purchase. This comparison is based on the proposed design, not a working product.
Overview
CPAP is the gold standard sleep apnea treatment. A traditional CPAP machine includes the following components:
- Machine that connects to an electrical outlet and generates a continuous flow of air
- Tubing that connects the machine to a mask to deliver the pressurized air
- Mask that fits securely over the sleeper’s nose or nose and mouth
To use a CPAP machine, the user must connect the components, fill the humidifier with distilled water, secure the facial mask, and turn on the machine. Regular cleaning and replacement of CPAP machine components is essential.
In contrast, the entire body of the micro-CPAP device rests under the nose during sleep, according to the proposed design that’s still in development. The device would contain a small, lightweight battery, and as a result, the micro-CPAP wouldn’t require an external power source, hose, or mask.
Humidity Control
The majority of traditional CPAP machines come equipped with built-in humidifiers to address the common complaint of dry nose and dry mouth among CPAP users. Many CPAP machines also offer heated humidification, which actively warms the humidifier water to provide warm and moisturizing air during therapy.
The current micro-CPAP device design doesn’t include humidification to address nasal dryness. The manufacturer states humidification isn't needed, because the device doesn't blow excessive air into the nose. It should be noted that in order to be effective, a micro-CPAP likely would need to administer similar pressure to traditional CPAP devices.
Pressure Settings
When initiating CPAP therapy, a doctor prescribes a CPAP pressure setting tailored to the specific needs of each sleeper, commonly expressed in centimeters of water pressure (cm H2O). The typical range for traditional CPAP pressure settings spans from 4 to 20 cm H2O, with the majority of CPAP users prescribed a pressure setting between 8 and 10 cm H2O.
It's unknown if micro-CPAP devices will be capable of offering a range of air pressure settings comparable to those of a traditional CPAP machine. The company developing micro-CPAP technology claims the device will be able to reach a pressure above 20 cm H2O, but a February 2020 update revealed they’re having difficulty creating the needed pressure.
Pressure Relief Features
The company developing a micro-CPAP device has stated that their initial micro-CPAP devices will be available at set pressure levels. This would mean they couldn’t offer pressure relief or pressure ramp options, which involve changes in air pressure. However, future micro-CPAP devices may have auto-adjusting pressure levels.
Pressure relief is a standard feature on most currently available CPAP machines. This feature reduces air pressure during exhalation to increase comfort, while still keeping the airway open. A pressure ramp is another common CPAP feature. With this feature, air pressure starts low, so the person can more easily fall asleep, then gradually increases to the prescribed pressure level.
Lifespan
A single micro-CPAP device is intended to be used for only one night of sleep, or for eight hours. With proper maintenance, a traditional CPAP machine can be used repeatedly and may last 12 years or more.
The manufacturer has stated that they are investigating a way to use rechargeable batteries for the micro-CPAP, which could give the device a longer lifespan.
Do Micro-CPAP Devices Successfully Treat Sleep Apnea?
Since they’re still in development, it’s unknown how effectively micro-CPAP devices will treat obstructive sleep apnea, or if the design concept is even plausible.
The devices aren’t currently FDA-approved or available for purchase. Once the development is complete, micro-CPAP technology will need to undergo testing to find out whether it is effective, and then earn approval from the FDA.
The timeline for these steps is currently unclear. The last update from the company developing the technology came in 2023. At that point, many individual components of the technology were working, but the company hadn’t yet been able to unify it into one device. They declared their intention to submit a different product called a Smart Mask to the FDA for approval to sell sooner, and to use the funds to continue developing the micro-CPAP. However, as of 2026, the Smart Mask has not been approved by the FDA and isn’t available for purchase.
Note that some low-priced devices that resemble the micro-CPAP design have emerged for sale in online marketplaces. These are not FDA-approved or intended to treat OSA.
Are There Alternatives to Micro-CPAP?
Besides standard CPAP therapy, several alternative treatments for OSA have emerged that some people may find more comfortable or convenient.
- EPAP therapy: EPAP therapy is an emerging therapy for OSA that consists of a small valve that attaches to the nostrils. The valve uses the sleeper’s breath to create pressure that helps keep the airway open. Studies suggest that EPAP can be effective at treating mild or moderate sleep apnea.
- Oral appliances: Sleep apnea mouthpieces have been found effective for treating mild to moderate sleep apnea. These devices reposition your jaw or tongue so that your airway stays open during sleep.
- Hypoglossal nerve stimulation: In this surgical treatment, a small implant near the collarbone delivers gentle pulses to stimulate airways and keep them open. Studies have shown that this therapy is a safe and effective way to treat OSA.
- Medication: Zepbound (tirzepatide) is a prescription medication approved to treat obstructive sleep apnea in adults with obesity. By promoting weight loss, it may reduce breathing interruptions during sleep and can be used alone or alongside CPAP therapy.
Frequently Asked Questions
