Obstructive sleep apnea (OSA) is a very vexing and even dangerous sleeping disorder. It causes very heavy snoring, sleep disturbances and it will often result in you feeling tired and irritable all day. Luckily, we have CPAP machines to assist us.

In our opinion, the one CPAP machine that stands out to us the most is the Apex Medical iCH II Auto machine. Yes, it is expensive, but the additional features and updated technology are what truly stand out as an impressive piece of technology. Also, the small size footprint makes it ideal for smaller nightstands and travelling – an added bonus for those constantly on-the-go.

The 5 Best Selling CPAP (Sleep Apnea) Machines:

For your convenience, the below list shows the 5 best selling CPAP machines on Amazon.com. The list is automatically updated once a day.

These devices are designed to introduce a steady stream of air via a mask into your airways in order to keep them open. These machines help to avoid disruptions in sleep and are very beneficial to those suffering from sleep disturbances.

CPAP stands for continuous positive airway pressure and these machines help patients with OSA breathe easier while sleeping. A CPAP machine is designed to increase the air pressure in a patient’s throat so that their airway does not collapse when breathing. These machines are very important for sleep disorders as they can be considered life-savers to some.

*Note: Several Philips Respironics CPAP machines are no longer listed on Amazon and have been “replaced” by the Respironics DSX600T. We do not know when or if this will change, but you’re safe going with the DSX600T option.

This article provides a helpful overview and quick reviews of the top 5 CPAP machines that will help you manage obstructive sleep apnea and provide overall better sleep by keeping your airways open at all times. Get ready to sleep better with these life-saving and useful machines.

1. Apex Medical iCH II CPAP (Sleep Apnea) Machine

Apex Medical iCH II with PVA and Built-In Heated Humidifier Second Generation

This Apex product is not your average CPAP machine. The iCH II Auto is quite new on the market and comes with enhanced features like added compliance data on the display, enhanced auto-titration algorithm for additional comfort, and a lighter/smaller power supply.

The added feature of the Pressure Variation Algorithm (PVA) is a huge bonus that provides relief to consumers who experience CPAP pressure discomfort. PVA reduces the pressure during exhalation to provide added comfort.

Another great feature of the iCH II Auto is the built-in heated humidifier with anti back-flow humidifier design. The machine effectively provides moisture to help combat dry nose or sore throat, whether you’re at home or travelling.

This CPAP machine also has one of the smallest footprints allowing more space on the nightstand for other items. This space-saving feature also allows for this machine to be transported with ease, making traveling with your CPAP machine a breeze.


  • One of the smallest footprints on the market

2. DreamStation 500 Auto CPAP (Sleep Apnea) Machine

DreamStation – DreamStation Auto 500

The DreamStation 500 Auto is a very adaptive machine. It features many auto-adjust functions that will make using this machine a breeze. DreamStation 500 Auto also comes with a built-in humidifier that can be easily taken off and cleaned, and this machine is considered one of the most advanced on the market today.

The device has something called the EZ mode. This mode makes the machine start out slow and move on up, gradually increasing the pressure. This is excellent for first-time users as this gives them an opportunity to adjust.

The humidifier is also auto-adjustable as it has a sensor that lets it detect the temperature and humidity level of the air in your bedroom. It will then adjust to the temperature to avoid problems such as dryness of the nose or mouth.

DreamStation Auto 500 is compatible with all masks and tubes and is very simple to setup.


  • Auto-adjustable air pressure level
  • Runs seamlessly and quietly
  • EZ mode is very useful for first-time users

3. Apex Medical XT-Fit CPAP (Sleep Apnea) Machine

Apex Medical XT-FitCPAP Machine

Another great Apex Medical model is the XT-FitCPAP Machine. Among the lightest and smallest on the market, XT-FitCPAP is perfectly suited for traveling. It can also operate in the range of 100-240 V, making it viable for use in countries outside the USA. It does not come with a humidifier, however this Apex Medical model is significantly cheaper than the CPAP machine mentioned above.

This device is very adaptable to its user through the Auto-Adjusting Algorithm. This algorithm allows the machine to adjust to your breathing and increase or decrease the pressure.

The same thing happens with the humidifier (if you are using one), as the machine will regulate the humidity to make sure there is no condensation in the tube or mask. With this controlled regulation, you won’t have to experience dryness.

The device also features an auto-adjustment for leaks. If the mask should leak air, XT will make sure that you get enough air and it will compensate for the leakage. The device will also compensate for air pressure differences up to 8000 ft., and will adjust for your breathing cycle by reducing the pressure as you exhale to ensure a more comfortable therapy.


  • Very small and light, perfect for traveling

However, different from the XT Auto, the XT Fit does not come with automatic features. The machine is, however, every effective despite the lack of these modes, and you can easily personalize the machine.

XT Fit has a very neat LCD screen (as does Auto) which you can use to track data and set up the machine every night. The humidifier comes with this item, and it has a sensor that lets is adjust to the humidity and temperature in your room, as well as increase the humidity if it determines that the patient will benefit from that.
