Integrated Heated Humidifier - ResMed AirSense 11 vs 3B Medical Luna G3 

Both the AirSense 11 and the 3B Medical Luna offer some type of integrated heated humidification. This feature helps keep the pressurized air you breathe during CPAP therapy moist, so you do not develop side effect or sore throat, or nasal irritation.  

For the AirSense 11, the heated humidifier is handy and reduces the size of the unit on your nightstand, but otherwise is common to most CPAP humidifiers. The 3B Medical Luna has the added pre-heat feature, which lets you heat up the water in your humidification chamber ahead of time, so it is ready when you are ready to fall asleep. 

This feature sets 3B Medical apart in terms of convenience. Users do not have to wait for the heated tubing to warm up like you would with the AirSense 11. Both machines have the advantage of heated tubing which can help prevent rainouts. 

Design Features -  ResMed AirSense 11 vs 3B Medical Luna G3 

3B Medical Luna G3

With the integrated humidifier, both the AirSense 11 and the 3B Medical Luna offer a much smaller footprint compared to CPAP machines that have an external humidifier. Both machines are also fairly lightweight. So even though they are not designed for travel, either machine could be easily packed into a suitcase. The Medical Luna G3 Is designed for efficiency so it appears very streamlined but may not be the most attractive item to leave out on your nightstand.  

ResMed AirSense 11

The AirSense 11 does have a remarkably sleek design that makes this unit more aesthetically pleasing. The modern look is stylish and functional and appears more like a modern home appliance than a piece of medical equipment.  For those who want their CPAP machine to be more than functional, the AirSense 11 wins in the design category.  

Screen - ResMed AirSense 11 vs 3B Medical Luna G3 

The modern touchscreen is a design benefit for both the ResMed AirSense 11 and the 3B Medical Luna. Both machines offer this innovative and easy-to-use feature that allows most users with little technical knowledge or skill to navigate on the machine. Users can easily change settings, review sleep data, or monitor settings without effort. However, the ResMed AirSense, because of its distinctive design offers a far more visually pleasing screen. Remarkably, the design of the AirSense still includes two large start and stop buttons making it easier for elderly patients. But this design feature does not detract from the overall look.  

The 3B Medical has a more integrated screen with handy info including access reminder checklists that will help keep your therapy on track,  a clock, humidity controls, and temperature controls. 

Overall User Experience - ResMed AirSense 11 vs 3B Medical Luna G3   

The ease of use for any medical device is essential and the designers of both the AirSense 11 and the 3B Medical have stepped up with intuitive user experiences. The 3B Medical has a very user-friendly interface display so that all the features patients need for a successful CPAP therapy can be found without frustration. You can quickly access this screen to adjust settings and customize your therapy.  

Because the ResMed AirSense 11 offers more bells and whistles, it can be a challenge for some, but overall, the design makes it easy to find what you need on the device and effortlessly perform most of the basic operations without assistance. Both devices work hard to make CPAP therapy easier, so it is difficult to decide which one is more user-friendly.  

Data Transfer - ResMed AirSense 11 vs 3B Medical Luna G3 

Data transfer is one of the latest features of CPAP machines. You can store and send your sleep data directly to your doctor. Even for novice users, this feature comes in handy and is available on both units. The easy user interface of the Luna G3 makes accessing your reports easy. With the 3B Medical Luna G3, you will never have to wait to get your reports. The device must be connected to your Wi-Fi, that way sleep data will be properly stored and able to be sent to your doctor for further review.  

The AirSense 11 also records your therapy data for viewing and adjusting by your care provider if required. The data is transferred to your care provider through a wireless network or an SD card.  

User Guidance - ResMed AirSense 11 vs 3B Medical Luna G3 

Having guidance through CPAP therapy is a useful feature, especially for new users who know nothing about CPAP. The ResMed stands apart with this feature offering the Personal Therapy Assistant in myAir™ which guides patients through equipment setup and acclimation by providing interactive voice-guided video instructions. The AirSense 11 also includes  Care Check-In which asks time-based check-in questions throughout the first month of therapy and provides tailored coaching and support to help troubleshoot common therapy issues. 

The 3B Medical Luna G3 unfortunately does not have these high-tech features. For that reason, the 3B Medical Luna G3 might be better suited with users who have already experienced CPAP therapy and know how to handle different aspects of it without additional assistance. That makes the AirSense 11 a much better CPAP machine for new users.  

Other Important Features - ResMed AirSense 11 vs 3B Medical Luna G3 

There are some features that set the two machines apart. 

The ResMed AirSense 11: 

  • Availability of over-the-air software upgrade 
  • The quiet Easy-Breathe motor 
  • The built-in ambient light sensor 

The 3B Medical Luna G3: 

  • The pre-heat feature 
  • Accessory and supply reminder 

The ResMed AirSense 11 features are very helpful for new users. Those who struggle with CPAP may find the Personal Therapy Assistant and Care Check-in useful for developing a discipline for CPAP therapy when first starting out. Other features like event detection can help identify central sleep apnea, respiratory effort–related arousal and Cheyne-Stokes respiration events to provide treating physicians valuable insight into the continued health of their patients. 

The 3B Medical Luna G3 is more useful for CPAP therapy patients who already have experience with the pitfalls of CPAP therapy. The machine is light on unique features to help new users through the initial periods of CPAP compliance. But at a lower price point this unit is reliable and effective for experienced users.  

ResMed AirSense 11 vs 3B Medical Luna G3 - Which Is Better? 

Choose the ResMed AirSense 11 if you are new to CPAP therapy. This machine will help you stay on track with your prescribed therapy and help you through the initial discomfort that many new users experience.  

The 3B Medical Luna G3 is a more affordable CPAP machine that helps sleep apnea patients who are upgrading to a better machine or switching to a different CPAP machine. It offers the best features that experienced patients may already value for their therapy.
