A continuous positive airway pressure (CPAP) machine is a medical device for treating obstructive sleep apnea (OSA). An estimated 10% to 30% of U.S. adults experience OSA symptoms. CPAP therapy can be highly effective, but if you’re new to this form of OSA treatment it can be hard to know what to look for when buying a CPAP machine.

We’ll help you understand how CPAP works, the different types of CPAP machines available, and how to navigate the buying process. We’ll also share the most important features to consider so you can find the best CPAP machine for your needs.

How We Make Our Picks

Our team has a strong knowledge base when it comes to the fundamentals of sleep apnea and CPAP products. We also know it can be difficult for consumers to wade through all the CPAP machines on the market.

To make it easier for you to find a CPAP machine that meets your needs, we’ve researched dozens of models. After looking at the most trusted brands and comparing features, availability, and customer reviews, we selected the best CPAP machines across a range of categories.

 

What Does a CPAP Machine Do?

A CPAP machine is an electronic device designed to treat people who have been diagnosed with sleep apnea. CPAP machines contain a mechanical blower that creates a continuous level of pressurized air. The device delivers this stream of air to a person’s airway via an airtight mask that connects to the machine with a hose.

How a CPAP Machine Works to Relieve OSA Symptoms

Obstructive sleep apnea causes frequent blockages in the airway that interrupt breathing during sleep. CPAP machines help keep the airway open by delivering a continuous stream of pressurized air through a mask that rests over the user’s nose or nose and mouth.

Types of CPAP Machines for Sleep Apnea

Traditional CPAP machines with a tabletop design tend to be the most widely available models. However, there are other types of PAP machines that can be useful for travel, increased comfort, or less common forms of sleep apnea.

  • CPAP: Continuous positive airway pressure machines, which deliver a constant rate of pressurized air, are typically the first-line treatment for people with OSA.
  • Travel CPAP: A travel CPAP is a smaller, lightweight version of a traditional CPAP machine. Designed to fit easily into your luggage, a travel CPAP makes it more convenient to stay on top of your CPAP therapy while on the road.
  • BiPAP: A bi-level positive airway pressure machine delivers a lower pressure level when you exhale than when you inhale. Your doctor may recommend a BiPAP machine if you have trouble tolerating CPAP therapy. It’s also a common treatment option for people with central sleep apnea.
  • APAP: Automatic positive airway pressure machines adjust the pressure level in response to your breathing patterns. This form of PAP therapy may be useful for people who find the continuous pressure of CPAP uncomfortable. Some CPAP and BiPAP machines also have APAP modes.

How to Find the Best CPAP Machine for You

To find the best CPAP machine, you should consider your budget and which features are most important for your needs.

CPAP Machine Pricing and Sizing

The cost of CPAP machines varies widely depending on the brand and features included, but most are priced between $500 and $1,000. BiPAP and APAP machines generally cost more due to their more advanced functionality.

Modern CPAP machines are fairly compact and lightweight. Models typically weigh between 3 and 4 pounds and are generally less than a foot in length. Most CPAP machines can fit on a nightstand.

CPAP Machine Pressure Ranges and Noise Levels

Pressure Ranges
Noise Levels

The average CPAP pressure setting is around 8 to 10 centimeters of water pressure, but most CPAP machines offer pressure levels from 4 to 20 cm H2O to give you and your health care provider flexibility in your treatment.

The average noise level for a CPAP machine is 30 decibels, which is equivalent to a low whisper. Some models have quiet motors and noise abatement features that can bring the noise level down further for light sleepers.

CPAP Data Tracking, Ramp Settings, and Smart Features

Data Tracking
Ramp Settings
Smart Features

Some models can detect and store key sleep data such as respiratory events. This can help your health care provider track your symptoms and make adjustments as needed. 

A ramp is a setting that starts at a low pressure and slowly increases the machine’s pressure over a set time to make it easier to fall asleep.

Modern CPAP machines often come equipped with smart features such as Wi-Fi connectivity, preheat functions for humidifiers, and LCD displays to make your CPAP experience easier and more comfortable.

CPAP Accessories and Compatibility With Your Machine

You generally need to purchase CPAP accessories separately from your CPAP machine. While some are vital to your CPAP therapy, others are completely optional. At a minimum, you need a well-fitting mask and CPAP hosing to connect your mask to the machine.

Other accessories like a CPAP humidifier can make your therapy more comfortable but are not essential. Remember to check the manufacturer specifications to verify that any accessories you purchase are compatible with each other and your CPAP machine.

CPAP Masks, Cushions, and Headgear

A properly fitting CPAP mask creates a seal to help deliver pressurized air from your CPAP machine. There are several styles of CPAP masks, including nasal masks and nasal pillows that deliver air to the nose and full-face masks that cover both the nose and mouth. The best type of mask depends on your sleep style, comfort preferences, and whether you breathe mainly through your mouth or your nose.

A cushion refers to the soft mask insert that comes into contact with your face. You can usually detach the mask cushion for cleaning and replacement.

Headgear helps hold your CPAP mask in place and keeps it sealed on your face. CPAP headgear usually features flexible straps and may include foam padding and Velcro.

CPAP Hosing

CPAP hosing refers to the long, flexible plastic tubing that connects your mask to your machine. CPAP machines often come with hosing, but this accessory needs regular replacement. CPAP hoses come in various lengths, and some versions contain heating elements designed to prevent condensation from forming if you use a humidifier.

CPAP Filters

Most CPAP machines come equipped with a filter to remove dust or other small particles from the air. CPAP filters need regular replacement. You can also purchase reusable CPAP filters, but these require frequent cleaning and still need occasional replacement.

CPAP Mask Liners

CPAP mask liners are an optional accessory that create a barrier between your skin and the mask cushion. Mask liners are a good option for sleepers with sensitive skin who experience irritation from wearing their CPAP mask all night.

CPAP Humidifiers

A CPAP humidifier increases the moisture in the air that your machine delivers to your airway. This can prevent dryness and irritation in the nose and throat and may be helpful for sleepers who live in a dry climate. Note that some CPAP machines have built-in humidifiers, but you can also find standalone units that connect to your CPAP machine.

Can You Use Purified Water in a CPAP Machine?

It is safest to use distilled water in your CPAP humidifier. While purified water is filtered to remove chemicals, it may contain mineral content. Additionally, some manufacturers remineralize bottled water to add healthy minerals for people to consume. This mineral content may cause buildup in your machine that can damage its components.

CPAP Batteries

An external battery is another optional accessory. A CPAP battery allows you to continue your CPAP therapy even when you don’t have access to an electrical outlet. This is a good solution for people who frequently travel or go camping. However, keep in mind that not all CPAP machines are compatible with an external battery.

CPAP Prescription, Insurance, and Purchase Information

Paying out of pocket for a CPAP machine can be pricey, but many insurance plans can help cover the cost.

Do You Need a Prescription for a CPAP Machine?

Purchasing a CPAP machine requires a prescription from your doctor. The Food and Drug Administration (FDA) classifies CPAP machines as Class II medical devices. While this helps ensure the safety and effectiveness of CPAP machines sold in the United States, it also means you need a prescription to buy one.

Does Your Health Insurance or Medicare Cover CPAP Costs?

Most health insurance plans cover at least part of the cost of CPAP therapy. For Medicare coverage, you will need to receive an OSA diagnosis following a lab-based or at-home sleep study.

Assuming you meet specific requirements, Medicare will cover a three-month CPAP trial. After the trial period — and if you demonstrate that you are adhering to CPAP therapy and it is improving your symptoms — Medicare covers 80% of the cost of the machine rental and supplies after you meet your Part B deductible. If you continuously use the machine for 13 months and make your share of the rental payments, you’ll then own the machine outright.

For private health insurance, the level of coverage depends on the specifics of your plan. Some providers may directly reimburse you after you buy a CPAP machine, though you’ll likely need to submit a claim form. Others may use a rent-to-own system where you pay a monthly fee for a CPAP machine during a specific time frame.

Where Can You Buy a CPAP Machine?

There are many options for buying a CPAP machine, including online, at a brick-and-mortar store, or through your doctor or sleep specialist. Buying a CPAP machine online or in-store usually provides the best selection. Keep in mind that while third-party retailers often have lower prices, they are usually out-of-network for insurance purposes. Check with your insurance provider regarding coverage prior to purchasing a machine if you aren’t planning on paying out of pocket.

Buying a CPAP machine from your doctor’s office or a sleep center may make it easier to coordinate reimbursement with your insurance company. Your physician or sleep specialist can also give you recommendations based on your symptoms and handle the paperwork for insurance coverage.

How Do You Clean a CPAP Machine?

We recommend that you follow any care and cleaning instructions from your CPAP machine’s manufacturer. That said, you can clean most CPAP accessories with a combination of warm water and soap. Use a mild soap and avoid harsh detergents or chemical cleaners. It’s important to clean your CPAP components regularly to avoid buildup of germs as well as skin residue and oils.

After washing your mask, hose, and other CPAP accessories, rinse them with cool water and air-dry. If you use a CPAP humidifier, the tank can be cleaned with a mixture of equal parts warm water and white vinegar.
