Continuous positive airway pressure (CPAP) therapy can improve the quality of life for those with obstructive sleep apnea (OSA). CPAP adherence is crucial to reducing daytime sleepiness and improving other health factors like lower blood pressure. Travel, however, can disrupt your normal sleep patterns. A portable CPAP machine like the ResMed AirMini helps users maintain routine treatment when away from home. 

ResMed specializes in medical equipment used to treat sleep apnea. The San Diego-based company makes four types of positive airway pressure (PAP) machines:

  • AirSense 11
  • AirCurve 10 BiLevel
  • AirSense 10
  • AirMini Portable CPAP

The AirCurve 10 is a bilevel positive airway pressure (BiPAP or BPAP) machine that delivers higher pressure during inhalation and lower pressure upon exhalation. The other three series are CPAP devices, meaning they provide fixed pressure throughout the night. The CPAP machines also have automatic positive airway pressure (APAP) modes to accommodate each sleeper’s unique needs. 

We’ll cover the ResMed AirMini, an exceptionally small travel CPAP machine. The model is essentially a smaller version of the best-selling AirSense 10 CPAP Machine. The AirMini, however, is distinctive for its waterless humidification system. This gives users all the benefits of moisturized air without the bulk of a traditional humidifier. 

We’ll highlight the AirMini’s features and overall performance as well as pricing, warranty, and shipping policies to help you decide if it’s the right model for you.

ResMed AirMini Video Review

Our in-house product expert explores how a ResMed AirMini operates — and who it’s a good fit for. We’ll take a close look at the machine’s lightweight design while examining its pros and cons.

ResMed AirMini CPAP Machine Review Breakdown

ResMed’s AirMini is a travel-friendly positive airway pressure (PAP) machine used to treat OSA. The small device delivers pressurized air to the upper airways through an ultra-slim tube and mask. This helps prevent apneas, or pauses in breathing when a person sleeps. 

The device has both CPAP and APAP settings. The CPAP setting delivers fixed pressure, but the level can be set in advance. The APAP setting automatically adjusts pressure levels based on a sleeper’s breathing patterns. The machine also features an AutoSet for Her mode, which addresses sleep apnea needs unique to women. 

An AutoRamp feature gradually increases pressure levels so users can fall asleep more easily. Expiratory pressure relief (EPR) lowers pressure levels during exhalation to make therapy more comfortable, and the HumidX cartridge uses Heat and Moisture Exchange (HME) technology to naturally increase air humidity. This waterless humidification system is designed to minimize nasal congestion and sore throats.

Smart Start/Stop automatically begins therapy when a user fastens their mask and stops therapy once the mask is removed. The AirMini app tracks compliance, stores sleep data for up to 30 days, and detects mask leaks. The machine is also approved by the Federal Aviation Administration (FAA) for in-flight use.

What’s Included

The ResMed AirMini is a compact device that operates on power. A small motor pumps pressurized air through a slim tube and CPAP mask, which helps normalize breathing by keeping a person’s upper airways open. 

The machine comes with some essential components, but compatible tubing and mask kits must be purchased separately.

Product Features

The ResMed AirMini has several features that help increase therapy compliance and comfort. 

With Smart Start/Stop, the machine automatically begins therapy as soon as you put your mask on and stops once you remove it, helping users ease into therapy. 

AutoRamp starts with a low-pressure setting and slowly increases airflow to the prescribed level. Most people find it easier to fall asleep when air pressure gradually increases. AutoRamp also helps new CPAP users adjust to therapy. 

Expiratory pressure relief (EPR) automatically lowers air pressure during exhalation to make breathing feel more comfortable. This feature benefits those who have trouble exhaling with higher pressure settings. 

Standard CPAP humidifiers can be quite bulky, but the AirMini has an innovative waterless humidification system. Instead of using a heated water tank, a small insert between the tube and mask vent retains heat and moisture from a user’s breath. Using a humidifier can minimize nasal congestion and throat irritation. 

The AirMini has three therapy modes. A CPAP setting delivers fixed airflow throughout the night. The AutoSet mode adjusts pressure levels according to a user’s breathing patterns, and AutoSet for Her features an auto-adjusting algorithm based on the sleep apnea needs of women.

The AirMini app tracks user compliance, mask leaks, and nightly sleep scores. Medical providers can also adjust settings remotely using the app. 

  • Smart start/stop: The AirMini starts and stops therapy when it senses the mask is on or off the user’s face.
  • AutoRamp with sleep onset detection: The machine starts therapy on a low-pressure setting and gradually increases airflow once a user falls asleep.
  • Expiratory pressure relief (EPR): Air pressure automatically lowers during exhalation to make breathing more comfortable.
  • CPAP mode: This setting delivers continuous pressure throughout the night. The precise pressure level is programmable.
  • AutoSet mode: This mode automatically adjusts air pressure levels based on a sleeper’s needs.
  • AutoSet for Her mode: This is an auto-adjusting algorithm based on the unique pressure needs of women.
  • HumidX waterless humidification: A small insert inside the tube naturally retains warmth and moisture to prevent nosebleeds, sore throats, and other symptoms caused by excessive dryness.
  • AirMini app: Using Bluetooth connectivity, the device tracks and stores important sleep data and monitors mask leaks. Medical providers can also adjust settings remotely via the app.

Sizing and Pricing

Weighing just 10.5 ounces, the AirMini is the smallest travel CPAP device on the market today. The compact design is about the size of a small alarm clock and slightly larger than a smartphone. It doesn’t take up much space on a nightstand, and it fits easily into a handbag. With its waterless humidification, travelers aren’t bogged down by cumbersome humidifiers. 

Size Comparison:

  • Travel: Most travel CPAP machines are under 10 inches long and weigh less than 2 pounds. At 5.4 inches long, 3.3 inches wide, and 2.1 inches tall, the ResMed AirMini is notably smaller than the average travel device. It’s also exceptionally lightweight, weighing just 10.6 ounces. 
  • Standard: Standard CPAP machines vary in size, but most are around 10 inches long, 5 inches wide, and 6 inches tall. They typically weigh at least 2 pounds. Water tanks can add notable bulk, but some models include built-in humidifiers. 

The AirMini is about half the size of a standard CPAP device. The ResMed AirSense 10, a standard CPAP model, is 10 inches long, 4.6 inches wide, and 5.9 inches tall. It weighs 2.75 pounds. Despite its much smaller size, the AirMini has similar features as the AirSense 10. 

Most travel CPAP machines cost between $500 and $900. The ResMed AirMini is slightly more expensive than the average portable device, but it’s suitable for both travel and occasional home use. Waterless humidification, APAP and CPAP modes, and an ultra-lightweight design might justify the higher cost for many users. 

Keep in mind that travel CPAP machines aren’t typically covered by insurance. That said, it’s still wise to double-check with your provider before making a purchase. Some plans may offer partial reimbursement on travel devices.

Device Performance

  • Noise level: It’s important to consider a machine’s noise level since it can impact your and your partner’s sleep quality. Most CPAP machines have an operating sound between 20 and 30 decibels. The AirMini has a 30 decibel sound level, which is considered whisper quiet. This is somewhat louder than ResMed’s standard PAP machines, which operate at 27 decibels. Even so, the AirMini is quieter than the average travel device.

    Some reviewers have noted that the AirMini is noisier than their at-home CPAP machine. Others describe the humming sound as pleasant white noise. The pitch may differ from standard models because of the machine’s small scale.
  • Ease of use: The AirMini’s streamlined design is simple to operate. While you can manually adjust settings on the device, downloading the AirMini app is advisable. Pressing the Bluetooth icon on the machine syncs the AirMini to your phone or tablet. The app guides users through setup and programming features like ramp time, pressure relief, and therapy mode. A Test Drive feature lets you try out therapy before your first night of use. Your doctor can also adjust settings remotely via the app.

    Both the app and user manual provide instructions for assembling the tube and mask. Assembly varies according to the mask style.
  • Portability: Living up to its name, the AirMini is the smallest travel CPAP machine on the market today. It’s not much larger than the palm of your hand, so it can be easily stored in a carry-on bag.

    Assembly and disassembly is straightforward since there are only a few main components. The grey end of the tube attaches to the machine. A twist connector on the tube houses the humidifier cartridge, so users won’t need to travel with bulky water tanks.
  • Pressure settings: The AirMini’s pressure range is 4 to 20 centimeters of water (H2O), which is standard for CPAP machines. Your doctor will prescribe a suitable pressure range for you.
  • Air-temperature control: The operating air temperature range for the AirMini is between 41 and 95 degrees Fahrenheit. Unlike most standard CPAP machines, users cannot adjust the air temperature. This could be a drawback for those traveling to extreme climates.
  • Humidity control: The optional HumidX cartridge increases air humidity to alleviate symptoms of dryness. Operating relative humidity is between 10% and 95%. Users cannot adjust humidity levels on the AirMini. Those visiting dry- or high-altitude environments may want to consider the HumidX Plus, which increases humidity more than the standard HumidX cartridge. HumidX Plus cartridges are sold separately.
  • Compatibility: Given its compact design, the AirMini is only compatible with certain ResMed masks:
    AirFit N30 Nasal Mask
    AirFit P10 Nasal Pillow
    AirFit F30 Full Face Mask
    AirFit F20 Full Face Mask
    AirTouch F20 Full Face Mask
    AirFit N20 Nasal Mask
    AirTouch N20 Nasal Mask

    HumidX cartridges are not compatible with F30 Full Face masks. Additionally, users should note the AirMini machine should be paired with ResMed’s AirMini Tubing.
  • Maintenance: Regular cleaning is crucial for effective therapy. CPAP masks should be washed after each use with warm water and mild detergent. The AirMini tubing should be submerged in a gentle soap and water solution at least once a week. Check for any cracks or holes each time you clean the tubing. Both the mask and tubing should be air dried away from direct sunlight.

    The filter and HumidX cartridge are both disposable. The filter and tubing should be replaced every six months, while the HumidX cartridge needs to be replaced every 30 days.

    Use a dry cloth to periodically wipe dirt and debris off the machine.
