I know this might not be a big deal to some people; but my old CPAP chamber was so difficult to get out and fill. I was constantly spilling and making messes. This unit is much better. The CPAP is quiet and it works. I use a Resmed P10 mask.

Buying Guide

When shopping for a CPAP machine like the Luna G3 Auto CPAP, there are several key features and specifications you should consider to ensure you’re making the best choice for your sleep therapy needs.

  1. Type of CPAP – Will you need a fixed pressure CPAP or an auto-adjusting CPAP (APAP)? APAP machines automatically adjust pressure throughout the night based on your needs. The Luna G3 APAP can also run in CPAP mode, meeting both needs.
  2. Pressure range – What is the pressure range of the CPAP? Most machines have a range of 4-20 cm of water pressure. Make sure it can meet your prescribed pressure needs.
  3. Ramp feature – Does it have ramp time or gradual pressure increase? This makes it easier to fall asleep when the machine starts.
  4. Heated humidifier – Look for a built-in or integrated heated humidifier. This adds moisture to the air to make therapy more comfortable.
  5. Heated tube – A heated tube keeps the air from getting cold and condensing in the tube as it moves from the CPAP to your mask.
  6. Noise level – Consider the decibel level of the CPAP. Quieter machines may help you and your bedpartner sleep better.
  7. Data and compliance tracking – Advanced models track daily use, mask leaks, AHI and more to help optimize therapy.
  8. Size and portability – If you travel often, look for a smaller, lighter machine with a travel bag or case.
  9. Mask compatibility – Make sure the CPAP works with the type of mask you will use – nasal, full face, pillows etc.
  10. Warranty – Compare warranties between models. Many come with 2+ years of coverage.
  11. Prescribed Pressure Needs – A key factor is making sure the CPAP can deliver your prescribed pressure range. This is set by your doctor based on your sleep study results. Those with severe apnea may need higher pressures.
  12. Comfort Features – Look for comfort features like a ramp function, EPR or C-Flex, and heated humidification which make therapy more comfortable and easier to adjust to.
  13. Advanced Data Tracking – Monitoring therapy data can help optimize treatment, so consider machines with compliance tracking and app connectivity.
  14. Mask Fit and Options – Your mask must fit properly and be the right style for you. Look for mask compatibility and sizing options.

Luna G3 APAP Alternatives

When it comes to sleep apnea therapy, it’s essential to find a machine that suits your specific needs and lifestyle. While the Luna G3 APAP is a highly-rated auto cpap machine, it’s not the only option out there. Let’s take a look at some alternatives from ResMed that might be worth considering: the AirSense 10 and the AirSense 11.

ResMed AirSense 10

The ResMed AirSense 10 is a top-rated CPAP machine that’s helped tens of thousands of people successfully treat their Obstructive Sleep Apnea. It comes in two versions: the standard model, which can connect to the internet and pair with ResMed’s MyAir mobile app, and the Card-to-Cloud (C2C) model, which does not include a wireless modem.

The standard AirSense 10 is equipped with a wireless modem, giving it the ability to wirelessly transmit therapy data and connect to the MyAir app. This can be a significant advantage for those who like to keep a close eye on their therapy progress.

On the other hand, the AirSense 10 C2C is the same as the standard model, minus the wireless connectivity. It’s an excellent option for those who prefer a simpler, more straightforward machine.

If you’re new to sleep apnea therapy or are looking to upgrade your current machine, the AirSense 11 might be the best choice for you. Its advanced features are designed to enhance your therapy experience and lead to better therapy outcomes over time.

In conclusion, while the Luna G3 APAP is a solid choice for sleep apnea therapy, it’s worth considering these alternatives from ResMed. Each offers unique features and benefits that can help you achieve a comfortable and effective therapy experience.
