Don’t go wrong with our comprehensive CPAP machine buying guide.

This article covers what to look for in a CPAP machine, how to choose a CPAP mask, some of the best CPAP machines, and other things to keep in mind.

When it comes to buying a CPAP (continuous positive airway pressure) machine, the process can be confusing and the options available are extensive. If you are experiencing symptoms of obstructive sleep apnea, there are numerous considerations that should be made when deciding which CPAP device to go with.

You will hear about things like automatic and continuous positive airway pressure, nasal pillows, fixed and auto variable pressures, and auto-ramp pressure features – without having a basic understanding of terms like these, deciding on a CPAP machine will involve a lot of guesswork. Especially when there are so many options out there! From budget machines to expensive, feature packed devices and travel machines, there is a lot that CPAP machines have to offer.

Whether it is the ResMed AirSense 10, a Philips Respironics DreamStation, or a Fisher and Paykel SleepStyle, the best CPAP machines come down to your personal needs. For the best CPAP machine and sleep apnea therapy experience, use this comprehensive overview to find a machine that best suits your sleep apnoea treatment needs.

The Features You’re Looking For

This section will provide a walkthrough of the main features found in a CPAP machine, and will help you to work out what you require for the best sleep apnea therapy experience. The main two features here will be the ventilator type, and the mask type, however there are numerous other features that will also be covered.

Choosing a Ventilator Type

CPAP machines come with two common ventilator types; fixed pressure and auto variable pressure. Either option may be suitable for you, depending on your personal needs.

Fixed Pressure Ventilators

Fixed pressure machines were the first CPAP machines to be available, delivering airflow at a constant rate. Offering a more simple and economical solution to sleep apnoea, most current fixed pressure machines have a multitude of extra features also found in auto variable models.

Auto Variable Pressure Ventilators

On the other hand, auto variable machines are designed to automatically monitor your airflow needs throughout the night, altering the air pressure output in response. This ensures that when using a CPAP machine you are receiving the lowest air pressure necessary, in turn increasing comfort and effectiveness.

Choosing the Right Mask

One of the most important decisions to make when setting up CPAP therapy is the type of mask chosen. The main options when it comes to masks are CPAP full face masks, nasal masks, and nasal pillow masks.

Full Face Masks

This mask type covers the mouth and nose, and is suitable for people that require higher pressure or breathe through their mouth. They are also ideal for people who sleep on their back, and those who have frequent congestions and nasal obstructions.

Nasal Masks

Nasal CPAP masks cover only the nose, delivering a natural, indirect airflow that is comfortable with higher pressure airflows. They are considered to be a middle ground between the bulky full face mask and the smaller, more manageable pillow mask. A significant downside to nasal masks is that they are not effective for people who breathe through their mouth during sleep, however a chin strap can be used to fix this.

Pillow Masks

CPAP pillow masks rest at the entrance of your nose, and are the most lightweight mask option available. Also referred to as nasal pillow masks, they are more suitable for people needing lower pressure settings, and also work well for people who move a lot during sleep and those with facial hair.

Other Features to Look Out For

With the main components out of the way, it is important to consider some of the extra features that may be included with particular CPAP machine models.

  • The inclusion of a humidifier is useful for the management of dry irritated airways, and is also suitable throughout winter and in colder areas.
  • In addition to this, a heated humidifier or hose can also significantly help reduce discomfort during use.
  • Breathing and sleep onset detection can dramatically simplify CPAP machine use, and make falling asleep more comfortable.
  • As sleep apnoea differs in women, many CPAP machine manufacturers offer gender specific CPAP machines.
  • For those who travel frequently, a smaller, lightweight travel machine may be useful. These often come with portable batteries and multiple plug-in adapters.
  • The noise emitted by CPAP machines is usually extremely quiet, however can vary depending on the machine.
  • Bluetooth, wifi and cellular connectivity is an important feature that can be useful for updating and monitoring purposes.
  • If you are asking the question “how long does a CPAP machine last?”, another important factor will be warranty coverage. This differentiates across brands, and is an important consideration to make.

Buying Options

Where to buy

When purchasing a CPAP machine, it is recommended to go through a reputable and experienced clinic. This ensures that you are buying effective, top of the line equipment, and allows for expert recommendation and guidance. Knowledgeable staff can help you choose the most appropriate CPAP machine, mask and accessories, and many clinics also offer take home trials and other useful sleep apnoea tests.

It is also a good idea to buy locally, as effective CPAP therapy may require multiple visits and ongoing consultation. Many clinics offer before and after customer service, and some manufacturers offer support programs to CPAP users as well.

  • It is recommended to choose a CPAP clinic that offers rental/free trial services, as well as sleep apnoea tests and personalised expert advice.
  • Many CPAP clinics offer free shipping on their products.


For additional support, there is a multitude of accessories available to help with CPAP equipment maintenance, sleeping, and convenience. These include:

  • Chin straps
  • Nasal pads
