Things to Consider

Those who suffer from breathing problems, such as obstructive sleep apnea find it difficult to get a restful and uninterrupted sleep. CPAP machines are a type of device that helps sleep apnea patients breathe better during their sleep, by sending a steady flow of oxygen to the nose and mouth. This helps sleep apnea sufferers keep their airways open and reduce breathing interruptions and snoring. Let’s have a look at how these machines function and what features you must consider before buying a CPAP machine.

What Is a CPAP Machine and How Does It Work?

A CPAP machine is like an air generator that comprises a compressor that generates a continuous flow of pressurized air, which is filtered and purified and directed towards a flexible tube. The flexible tube is connected to a mask that the user wears around their nose or mouth. The purified air, therefore, travels through the tube into the airways of the user, helping them receive a continuous stream of breathable oxygen throughout the night. These machines ensure that the airflow to your lungs is steady and prevents you from waking up at night due to breathing interruptions and disruptions.

Most models also come with a humidifier that helps regulate the air temperature and moisture, making sure that plenty of breathable air is available.

Type of Sleep Apnea You Have Is Important

The types of sleep apnea can vary. There are three types of sleep apnea machines that cater to different breathing and sleeping conditions. The two main types of sleep apnea are central sleep apnea and obstructive sleep apnea (OSA). The best machine for OSA is a CPAP machine, which usually comes in after completing your sleep study. A physician prescribes CPAP machines for sleeping, with a particular pressure value to help you breathe smoothly throughout the night. These machines give you the right amount of oxygen, with just the recommended pressure to get your breathing and treat your OSA.

Important Features to Consider Before You Buy a CPAP Machine

6 Most Reliable CPAP Machines to Help You Deal with Sleep Apnea

CPAP machines are not the cheapest of devices you can buy, therefore it is always best to consider certain features carefully before you make an investment. These machines have several features that you need to take into account and decide which ones suit your needs the best. The most important consideration is the type of sleep apnea you have, which ultimately dictates which kind of CPAP machine will work best for you. Secondly, there are some main features like the modes available, the ramp time, sound pressure, and dimensions that need to be considered. Moreover, you can also look at some extra features that offer a personalized touch to your purchase.

Operating Pressure Range

Perhaps the most important thing to consider before buying a CPAP machine is to check the operating pressure range. This is important because it determines the amount of pressurized air a machine is capable of providing. Doctors recommend different pressures to different patients of sleep apnea, depending on their sleep study and the specifics of their condition. If a machine does not operate within the recommended range of pressure, it will be useless for you.

Make sure to get a machine that has a wide pressure range, like our Premium Pick Devilbiss IntelliPAP Auto Bi-level MachineDevilbiss IntelliPAP Auto Bi-level Machine, and at least four times higher and lower pressure settings, so that if your physician changes the pressure prescription, you can still use your CPAP machine.

Sound Pressure Level

The sound pressure level is important to consider, especially if you prefer sleeping in stillness and silence. CPAP machines used to be noisy, which created a constant white noise throughout the night. This may not be a problem for some people who find white noise to be comforting and lulling, but others may find it irritating. Most new models of CPAP machines are made to have a very low sound pressure, which makes them less noisy and almost whisper quiet. If the sound is something that is particularly peeving to you, then make sure to check the sound pressure before you buy a CPAP machine for sleep apnea.

Humidifier Type And Capacity

Artificially breathing air through a CPAP machine can cause your throat and airways to dry up and cause irritation as well. This is why a humidifier is important. Most CPAP machines come with a built-in humidifier to combat this issue. You can also get a humidifier separately if your CPAP machine doesn’t have one; however, with the models in our list of the best CPAP machines, you get built-in humidifiers. You can also get detachable ones, which are easier to travel within case you don’t have space to carry the machine with you.


CPAP machines come with two types of filters, disposable ones, and non-disposable ones. This feature depends entirely on personal preference and the amount of time you are willing to spend on the maintenance of your machine. Some CPAP machines come with both filter options, while others can only accommodate either kind. Disposable filters require less maintenance but have a shorter life span, requiring frequent changes, while non-disposable filters may require cleaning every now and again.

Ramp Time

Another issue with artificial breathing is that it takes a while to get used to. Wearing a CPAP mask and adapting to the sudden airflow can be difficult, especially for those with moderate sleep apnea because it usually requires a high-pressure setting. A ramp is a comfort feature that most users look for in a CPAP machine. A ramp allows you to get used to the air pressure gradually, by moderating the airflow and slowly building it up to the recommended air pressure.

Make sure to look at the ramp range and time to see if it is suitable for you personally and compatible with your prescribed pressure. Check on this before buying a CPAP machine.

Hose Length

The hose connects your CPAP machine to your mask. You wear the mask while sleeping and place the machine near the bed, preferably on your nightstand. The hose length has to be long enough to cover the distance from your nightstand to your bed or wherever you decide to place your CPAP machine. Just make sure that the hose is long enough to allow room for comfortable movement and does not restrict your mobility while sleeping.

Size, Weight, and Portability

6 Most Reliable CPAP Machines to Help You Deal with Sleep Apnea

Make sure to check the size, dimensions, and weight of your CPAP machine if you travel frequently because a bulky and heavy machine will not be portable. Some machines are bigger but lightweight, which may take up storage or luggage space but are still easier to carry, while others are travel-friendly and smaller in size, like the Philips DreamStation Go Auto Travel CPAP Machine with Bluetooth on our list. Make sure to also check that your machine is compatible with a range of plug-in adapters, or have a portable battery option because these features come in handy during traveling.

Sleep Data

Newer models of CPAP machines, like the ResMed AirSense 10 above, come with a great feature of data recording. This is a useful feature to store and monitor your sleep information. Some CPAP machines record basic information like the duration of time you use the machine. However other more advanced models can record other information as well, such as the occurrence of apnea events, hypopnea events, certain changes in the pressure, instances of snoring, and leakage rates. This information is useful for your doctor or physician to track your progress and design new sleep regimes to improve your sleeping and breathing patterns during the night. You can also check daily, weekly and monthly averages using the data your CPAP machine records.


The rule of hand before making any purchases that are expensive is to check for a warranty. A warranty is basically buyers’ security and manufacturer’s guarantee in the quality of their product. It is best to look for a CPAP machine that comes with at least a 1-year warranty. This way if the machine gets damaged before time, you can get your money back or get it fixed. Some CPAP machine models also come with a trial period, so that the user can be more confident before making a commitment.


While both machines are used for sleep apnea treatment, they are different in the way they function. Continuous Positive Airway Pressure or CPAP machines usually use air pressure that has been generated by the machine. This air pressure travels through the tube and into the user’s mask, allowing them to sleep comfortably. On the other hand, BiLevel Positive Airway Pressure or BiPAP machines also deliver air pressure to the user’s face, but they deliver two pressures: inhale and exhale pressures.

It is recommended that you replace the filter at least twice a month or after every two weeks. Once your filter starts discoloration, it will be time for you to replace the filter. With clean filters, your machine will be able to deliver clean and fresh air, that is free of any extra particles.

The humidifier will be able to run without any water but it will be unable to perform its humidification functions. Moreover, if you do not want to run your CPAP with water, then you can turn the humidification option off.

Ideally, you should be using distilled water for your CPAP machine humidifier. This is because distilled or filtered water is free from any minerals or particles that you could possibly be breathing in. Filtered water is not only better for your health but also increases the life of your CPAP machine.
