If you’ve been diagnosed with sleep apnea, you’ve probably heard about the benefits of continuous positive airway pressure (CPAP) therapy. CPAP machines use pressurized air to keep your airway open as you sleep. While these devices can improve breathing for most people with sleep apnea, it can be hard to know what to look for when shopping for a CPAP machine.

We’ve created this guide to help you find the best CPAP machine that’s tailored to your specific needs. For more specialized guides, take a look at the best travel CPAP machines to take on the road and the best CPAP masks in both nasal and full-face designs.

How We Make Our Picks

Our testing team is headed by Dr. Breus and includes medical professionals, product experts, and researchers with decades of combined experience in sleep health and CPAP therapy. We use this expertise—along with a deep understanding of sleep apnea and CPAP technology—to evaluate which machines are truly worth recommending.

Because we know how overwhelming it can be to sort through the many CPAP options on the market, we research dozens of models from trusted brands, compare their features and availability, and analyze real customer reviews. We also monitor product recalls and manufacturer reputations to ensure that every CPAP machine we feature is high-quality, effective, and reliable.

How a CPAP Machine Works

CPAP therapy involves using a bedside machine that provides a steady stream of air to prevent breathing interruptions while you sleep. It’s particularly effective at treating obstructive sleep apnea (OSA), the most common type of sleep apnea. In OSA, tissues in the throat narrow or block the upper airway during sleep, repeatedly interfering with normal breathing.

A CPAP machine works by filtering and pressurizing air, which is then delivered to your airway through a hose and a mask. The force of the pressurized air splints the airway open to facilitate uninterrupted breathing.

What to Consider When Buying a CPAP Machine

When it comes to CPAP machines, there are a wide range of brands and models to choose from. Different CPAP machines offer unique combinations of features, so it’s important to consider what fits best with your lifestyle and needs.

Pressure Range

Air pressure delivered by a CPAP machine is measured in centimeters of water pressure (cm H2O), and most models can provide pressure levels up to 20 cm H2O. Some CPAP machines also come with a ramp feature to help you fall asleep. Ramp settings start therapy at a lower pressure before slowly increasing it to the prescribed level over a set period.

Noise Level

The average sound level of a CPAP machine is around 30 decibels, which is about as loud as a soft whisper. Some models have special features or designs that reduce the sound level even further. Quieter models may be particularly helpful for anyone who needs a quiet environment to fall asleep.

Smart Features

Many CPAP machines include smart features to make them more comfortable and easy to use.

  • LCD Displays: Some models have advanced displays that make it easier to navigate menu options, especially in the dark.
  • Data Tracking: All modern CPAP machines track some data to help your doctor evaluate the treatment’s effectiveness, but some models collect more data points and track your sleep patterns.
  • Cellular Connectivity: CPAP machines may collect your data on a memory card stored in the device, sync your data over cellular service to a cloud-based platform, or allow for a combination of both.
  • Preheat Function: Humidifiers are a common feature of CPAP machines that add moisture to air as it’s delivered through the hose and mask. Some CPAP devices have a preheat function that warms up the humidifier water before use.

Features like data tracking, easy-to-read displays, and pre-heating might seem like overkill, but they can improve daily use and CPAP adherence.

Types of PAP Machines

CPAP is one type of positive airway pressure (PAP) machine, though alternative devices are available with slightly different functions.

PAP Machine Description
Continuous positive airway pressure (CPAP) A standard CPAP machine offers a consistent level of air pressure throughout the night. Following a sleep apnea diagnosis, the appropriate air pressure level is typically determined during a titration study at a sleep clinic.
Bilevel positive airway pressure (BiPAP) BiPAP machines switch between two levels of air pressure: a higher level when you inhale and a lower pressure when you exhale. This type of machine may be prescribed if you have difficulty tolerating a fixed-pressure CPAP device or if you need treatment for another type of breathing condition, such as central sleep apnea.
Automatic positive airway pressure (APAP) APAP machines use sensors and algorithms to automatically adjust the air pressure level based on your breathing patterns. Rather than a machine itself, APAP is a technology that's available in certain CPAP and BiPAP devices. However, the term APAP machine is typically reserved for a CPAP device that includes an auto-adjusting feature.
Travel CPAP machines Designed for convenience and portability, travel CPAP machines are compact and lightweight. While functioning similarly to a standard CPAP machine, their small size helps you stay consistent with therapy even when you’re away from home. Many travel CPAP machines also have APAP modes.

CPAP Accessories

While a mask, tubing, and an air filter are essential components of CPAP therapy, other accessories can enhance your comfort and the effectiveness of treatment.

Accessory Description
Mask A CPAP mask delivers air to your nose or your nose and mouth. A mask needs to feel comfortable yet maintain a strong seal against your face to prevent leaks. Headgear keeps the mask in place.
Tubing CPAP tubing connects the machine to your mask. Hoses come in many different lengths and styles. Some models offer special features like in-line heating.
Filters Filters clean the air that is pressurized and delivered by a CPAP machine. FIlters may be washable or disposable and should be replaced according to the manufacturer’s instructions.
Battery CPAP batteries aren’t essential, but they can ensure consistent performance during travel or power outages. Some batteries are specific to one CPAP device, while others can be used with various models.
CPAP pillow CPAP pillows are designed to help you sleep while using a CPAP machine. These pillows have special shapes, cutouts, or other features that make it more comfortable to sleep while wearing a mask and headgear.

Compatibility is a major factor to think about when you’re shopping for a new CPAP. Make sure a machine will work with the mask and tubing you’ve got in mind before you commit to a purchase.

How to Buy a CPAP Machine

Buying a CPAP machine involves more than just choosing a device—it starts with getting the right diagnosis, prescription, and features to match your sleep apnea needs. Whether you’re new to therapy or upgrading an older machine, understanding the steps in the purchasing process can help you find a device that’s comfortable, effective, and reliable.

Prescription

A prescription from your doctor is required to buy a CPAP machine, as it’s considered a Class II medical device regulated by the U.S. Food and Drug Administration (FDA). Your prescription ensures the machine is programmed to the correct pressure settings based on your sleep study results, which is essential for safe and effective treatment.

If you haven’t been diagnosed yet, your doctor may recommend an in-lab sleep study or a home sleep apnea test before writing the prescription. Sleep Doctor offers an at-home sleep test that you can complete from the comfort of your own bed, and a board-certified sleep physician reviews your results and provides a prescription if sleep apnea is detected, making it easy to move from testing to treatment.

Cost

CPAP machines typically cost anywhere from $500 to over $1,000, influenced by factors like the brand, features, and any accessories included with your purchase. 

Insurance

Most insurance plans, including Medicare and Medicaid, cover some CPAP costs under certain conditions, including whether you demonstrate that you use your CPAP machine consistently. Even when covered by insurance, there may still be out-of-pocket costs like a copay or deductible.

If your plan offers reimbursement, Sleep Doctor provides an itemized receipt you can submit to your insurer, allowing you to take advantage of benefits while still enjoying the freedom to choose your preferred CPAP machine and accessories. This approach can offer the best of both worlds: flexibility, convenience, and potential cost savings.

Where to Buy

Once you have a prescription, a CPAP machine can be purchased online, in medical supply stores, and sometimes directly through doctors and sleep specialists.

Sleep Doctor offers a streamlined online shopping experience with a curated selection of CPAP machines from trusted brands, making it easier to compare features and find a device that's right for you. When you buy through Sleep Doctor, you get access to expert guidance, detailed product descriptions, and fast shipping, as well as the option to purchase replacement supplies and accessories in the same place.
