This identifies the machine as continuous, auto adjusting, or bilevel operation. This does not identify whether the machine automatically adjusts pressure. Auto adjusting refers to APAP, whereas BiPAP Auto is differentiated using the Auto Pressure Adjustment property. BiPAP machines are defined further using Spontaneous or Timed properties.
A CPAP machine blows one constant pressure of air into your passageway throughout the night. Your ideal pressure was determined during your sleep study.
A BiPAP machine delivers two separate pressures of air; One when the patient inhales and a separate pressure when they exhale. The machine alternates between the two set pressures to help optimize your sleep apnea treatment.
An APAP machine automatically adjusts on a breath by breath basis to blow the minimum pressure needed to keep your airway open during sleep. This allows your machine to provide you with your ideal pressure nightly.
Warranty is the length of time that the manufacturer will guarantee a product to be free of defects. Warranties vary in length depending on manufacturer, but generally all machines come with a 2 Year Warranty.

This is the level of sound the machine produces at a pressure of 10cm, standing 1 meter away or roughly 3 feet from machine. Measured in Decibels, the values also indicate whether the machine is considered a "quiet CPAP"; see Quiet property.
|30-dB||28 dB||29 dB|
This identifies which machines have a decibel rating of 29 and lower. This does not account for use with the humidifier attached, which could supply additional volume that can muffle or amplify sound. This property does not account for noise that travels through the CPAP tubing, seemingly sounding louder than the measured db rating.
This indicates which manuals are included with the purchase of a CPAP machine. Most all machines come with a patient manual; also called 'user manual', which may or may not have pressure setting instructions. Some machines come with both the patient and quick setup guide or both patient and clinician manuals.
Looking to travel? We have found some machines are easier to travel with than others. These smaller and more lightweight machines are still robust enough for constant daily use as well as travel.

|NA||5.7 in x 5.1 in x 3.9 in||7" x 5.5" x 4"|
This indicates which heated humidifier works best with the listed CPAP machine. In some instances, Built-in is used to describe a machine/humidifier combination system. The Fisher and Paykel HC150 was used for machines that do not have an integrated or built in humidifier system.
|Built In||XT Heated Humidifier||System One 60 Series|
Identifies which CPAP has a humidifier that is built into the CPAP. Built-In humidifiers cannot be separated from the CPAP machine.
|Heated Humidifier Type|
This property identifies how the machine incorporates a Heated Humidifier. Build In humidifiers are built into the CPAP machine and cannot be separated from the machine. Integrated humidifiers connect directly to the CPAP machine and they can only be used with compatible CPAP machines. With Integrated humidifiers, the CPAP machine, can be separated and used without the humidifier. CPAP machines that do not have a built in humidifier and do not have an integrated humidifier option have to use a Stand Alone humidifier as the machine's heated humidifier option. Stand Alone humidifiers can be used with any machine and connect to the CPAP machine with an additional hose.
|Ambient Rainout Reduction|
A yes in this field indicates the machine and humidifier have technology to reduce rainout, the water that collects in a hose when using a heated humidifier. Sensors measure the air temperature in the room and adjust the amount of heat and moisture delivered to the mask to reduce or omit rainout.
|Heated Hose||No||60 Series Heated Tube|
|Integrated Heated Hose|
This indicates that the machine has an integrated heated hose option to enhance humidification and reduce rainout. An integrated headed hose receives power directly from the machine and does not require a power supply. The tube's heat settings are set through the machine menu screen.
|Humidifier Water Capacity|
This is the maximum water capacity held by the chamber of the compatible humidifier.
|300 mL||325 mL|
|Auto Pressure Adjustment|
This property defines whether the machine automatically adjusts pressure to meet the needs of the CPAP user on a breath-by-breath basis. All APAP machines are defined as 'Auto Adjusting', but some BiPAP's also use an Auto feature on both the IPAP and EPAP. If not marked, Yes, assume the machine does not have AUTO capabilities.
A CPAP (Constant Positive Air Pressure) delivers continuous airflow at a prescribed pressure at 4cm to 30cm. APAP operates between a range and BiPAP machines are a mix of ranges and constant pressures. This pressure is measured in centimeters of water pressure (H2O) and 4-20cm is average pressure range on most CPAP machines.
|4-18.5cm H2O||4-20cm H2O||4-20cm H20|
|EPAP Pressure Range|
This Property lists the operating range for the Exhalation Positive Airway Pressure (EPAP). This is the pressure setting used when you exhale. EPAP is always lower than the IPAP (inhalation) pressure, making breathing out easier and more comfortable.
Pressure Relief is a feature that lowers your therapy pressure to help with difficulties breathing against the machine's airflow, providing a more comfortable and natural breathing pattern. Assistance can occur on the Exhalation, on the Inhalation, and on both exhalation and inhalation at the same time.
The Ramp feature allows the user to start treatment at a lower pressure to fall asleep with, gradually raising the pressure over a set time. This is a comfort setting and can set from 0 to 45 minutes on most CPAP machines.
This property defines whether the machine is capable of continuously blowing a constant pressure. All CPAP machines are defined as 'continuous', but some BiPAP's and APAP's also come with a CPAP mode; some BiPAP and BiLevel machines Do NOT. By setting the IPAP and EPAP to the same pressure, a CPAP Mode is achieved, preventing the EPAP pressure from dropping.
Leak Compensation is a machine feature that identifies mask leaks and adjusts to maintain the delivered pressure as set. If marked N/A assume the information is not available due to being out of production or unavailable.
|Max Operating Altitude|
This is the maximum altitude at which the machine will properly operate.
|8,000 ft (4-18 cm)||7,500 ft|
|Direct Battery Operation|
Indicates which machines have a DC port in which you can use to connect a battery pack or a deep cycle marine battery with an optional DC cable. This is different from an integrated battery that works only with the machine it was designed for. (i.e. Everest CPAP Machine) see property Integrated Battery
Domestic Voltage is the voltage that is used with a standard wall outlet in the United States and ranges from 100-120 volts. International Voltage can range from 220v-240v AC.
|100-240V AC||100-240V AC||100-240V AC|
|Optional DC Cable|
A 'Yes' answer indicates that the CPAP Machine has an optional DC cable that plugs directly into a DC port. This allows you to use a DC power source, such as a battery or car cigarette lighter outlet. Some optional DC cables include alligator clips to connect directly to battery terminals. See the "Power" tab of the machine's product page for more detailed information on how the machine works with alternate power sources, and what optional cables and batteries are compatible.
An integrated battery pack attaches to and functions seamlessly with the machine it is integrated with. It allows your CPAP to run on AC and fail over to the DC battery only if necessary.
Identifies which machines are data capable and have the ability to track your therapy progress over time. The machine captures key metrics like AHI (Apnea/Hypopnea Index), Leakage, and most pressure used. Depending on the machine, the data can be retrieved through an on Machine Screen Display (MSD), through Optional Software (OS), and/or through SmartCode (SC).
This property marks the machines that have the ability to record performance data on a removable card. Some machines that are flagged as having software (seeOptional Software), do not have removable memory cards, rather instead, records information on-board and must use a download cable to retrieve the data from the machine.
Software is an option on some CPAP machines. The software can give details on compliance and performance. The patient or physician downloads the data from the CPAP machine to determine how long a patient has used their machine each night and how well the machine is working to stop Apnea/Hypopnea events. This property shows the software package to use for machine that has the ability to transfer data to your computer and report Hours of Usage. See Advanced Software for a list of machines that can report AHI or Leakage.
|Auto Altitude Adjustment|
Altitude Adjustment is defined as the machine's ability to compensate for changes in altitude. Compensation can either occur manually or automatically. Manual adjustments occur within the Setup Menu and must be set by the user. Automatic requires no user intervention.
This feature turns the machines off and on when putting on or taking off the mask. When you put your mask on the machines senses you breathing and turns itself on. Take off the mask and the machine turns off.
|Mask Off Alert|
This feature detects excessive mask leaks due to poor cushion seal or when a user stops therapy by removing a mask when in use. The alert can be in the form of an audible alarm (ALARM) or a text message on the unit's LCD display (LCD).
Spontaneous (S) mode tells the machine to start blowing at IPAP pressure with no specific interval set. The machine must wait and detect a break in the breathing cycle before reacting, switching from exhalation to inhalation. If a backup rate is needed, then the unit will need a time interval setting and will be marked 'Yes' on the Timed property.
Timed (T) or Spontaneous Timed (ST) modes provide a customizable backup rate that forces the machine to switch from exhalation to inhalation. In ST Mode, the machine monitors the breathing cycle and switches from EPAP to IPAP once the backup time is met or whenever the break is detected through the sensors; whichever occurs first. The time aspect is only meant to act as a backup respiratory rate to the (S) function (see Spontaneous). This is used for patients with central sleep apnea, or those who need non-invasive mechanical ventilation.
|Designed For Her|
These machines were designed with a woman's lifestyle in mind.
|Back Lit Display|

Please note: The manufacturer warranty is voided by water damage or misuse of the machine.
"I have used my Sleepstyle 608 now for over a week, and have been extremely happy with the results.
My chief problem in using a CPAP machine has been humidity levels(too high or too low), and this machine has taken that completely away.
I struggled with CPAP because of low humidity, but adding an external humidifier only added to the problems. If I guessed the humidity levels wrong, I either woke up dried out like a desert, or awoke in the middle of the night with water gurgling in the tubes. I could never get the levels right, and so I gave up on CPAP.
With the 608 I am a believer again. I have have none of the issues that kept me from doing this important therapy.
This unit automatically adjusts to the ambient humidity according to a "comfort level" you can choose, and the heated air hose stops any condensation problems - I no longer have to guess what settings to use, and the machine has eliminated the frustrations of guessing wrong.
One thing I did find is that the breathing tube is not the proper size to fit the Innomed Nasal-Aire II mask. The fitting on the supplied heated hose is slightly too large. I had to wrap some electrical tape around the mask's swivel end to get them to seal, but it's a small issue.
Other positives include the ramp up time - I have not had any issues falling asleep beyond the first night (I had to get used to a mask/chin strap/machine again), and the water chamber is easy to fill (and comes with a spare). Also, the 608 is very very quiet - I don't think I have heard it once since I bought it.
Improvements I would suggest - Exhalation pressure relief, leak/mask off alarm, standardized fitting sizes.
All in all, I am very happy I bought this machine so that I could return to my CPAP therapy and not have to deal with the hassles of my old machine/humidifier.
If you or someone you know struggles with humidity levels with their CPAP machine, I would highly recommend the Sleepstyle 608."
"I really like this CPAP. It is easy to use, relatively easy to travel with. The fact that it is a simple cord (the voltage regulator is inside the CPAP) really helps when I go to pack it up. The heated hose is nice but note if it gets under a pillow and can get really warm to the touch. The only thing I wish is that it would come on automatically when I put on my mask like my resumed did."
"Very pleased. I hope to say the same in the winter. With my other machine I had a LOT of trouble with rain to the point that I almost gave up. The machine makes a big difference in the quality of sleep I receive."
"Very nice machine; quiet and easy to use. Quality is evident in construction and design. Humidifier works well and is easy to use and refill."
"Getting used to it slowly"
CPAP therapy provides a constant airflow which holds the airway open so that uninterrupted breathing is maintained during sleep. It is traditionally provided through a nasal mask that seals around the nose to maintain the pressure level.
We provide our customers with many tools to make informed decisions about their machine purchases. Options include:
We work very hard to provide many different ways for our customers to compare products. Here are the machine product guides we have created and maintain:
Machines come with a six foot hose, power cord, at least one filter, and manuals. Most manufacturers include a carrying case which is designed specifically for their equipment. CPAP / BiPAP / APAP machines do not come with a delivery system or mask. CPAP Masks must be purchased separately.
To see the list of what specifically comes with each machine, you can browse for a machine. Then on the product page, click the "Specs" tab to see a full list of what comes with the machine.
Yes, all CPAPs use at least one filter that is usually a type of foam material and washable. Some CPAPs offer finer filtration with the addition of a disposable paper filter.
Cleaning and changing filters is the only maintenance required for a CPAP machine.
The filters are located at the back of the machine at the air intake. The image below shows the black foam filter at the back of the Everest 3 CPAP Machine.
Yes. Federal law requires we have a valid prescription on file before we ship your mask, machine and/or humidifier.
We provide many easy ways to get your prescription:
The ramp button on a machine is a feature that allows for a gradual pressure build-up to your prescribed pressure. The feature is enjoyed by those with high pressures because they ease up to their pressure.
Exhalation relief is a comfort feature offered by two manufactures which reduces the air flow at the time of exhalation making the breathing process more natural.
The only care a CPAP or BiPAP machine requires is to clean or change the filters at the air intake. This keeps the internal parts from accumulating dust. Fine paper filters should be changed out every 30 days, or when they appear soiled. Foam washable filters should be rinsed with clear running water once a week, allowed to air dry, and reinserted.
There are some other suggested actions to care for your machine:
CPAP machines which record full data (such as AHI and leak info):
First you need to determine if your machine is configured to operate on DC power and has a DC power outlet. If your machine does have a DC power outlet and you want to run your marine battery, then you will need the correct DC cable for your machine and an adapter cable that fits over the cigarette lighter plug and ends in alligator clips.
CPAP.com sells complete battery kits with everything you need for your machine including the right cables for your machine and the battery. You can find the right battery kit for your machine here.
If your machine does not have a DC power outlet, then you will also need an inverter to be able to run your machine on battery power.
If you have questions about the specific power needs of your machine, review the "Power" tab on your machine's product page, or give us a call at 1-800-356-5221.
A CPAP prescription must contain all of the following information:
Many PAP users experience nasal congestion and dryness of the nose and throat during treatment. This can be especially problematic for new users who are adapting to treatment. Humidification adds moisture to the air helping to reduce the symptoms of dryness and congestion.
Nasal congestion also leads to mouth breathing, which perpetuates the problem of dryness. If this is an issue for you, try a heated humidifier.
A heated humidifier uses heat to warm the water to add moisture to the airstream. The heat is adjustable for more or less moisture. The water chamber for a heated humidifier is much smaller than a passover humidifier.
In our considerable experience of specializing in CPAP equipment we have found that patients who use a heated humidifier have a much higher rate of effectiveness to their CPAP therapy.
There are three types of heated humidifiers:
A "built in" humidifier is designed as a part of the CPAP machine and cannot be removed or separated from the CPAP machine. As with an integrted humidifier, it eliminates the need for a second hose or power cord. The water chamber can be removed for cleaning or replacement purposes.
The advantage of a "built in" humidifier is it makes for a more compact unit with fewer parts. This design also helps to ensure therapy effectiveness by including the heated humidifier with the CPAP machine thereby providing comfort to the CPAP user.
A disadvantage is that a built in humidifier may produce less moisture if used as passover because the surface area is typically smaller. Also, since the humidifier is "built in" to the machine, detaching it is not an option. This can be an issue for frequent travelers. Lastly, if the machine or humidifier stops working, the entire unit must be sent in for repair or replacement, not just the component that failed.
An example of a machine with a built in humidifier is the ICON Auto CPAP Machine with Built In Heated Humidifier and SensAwake as seen below.
CPAP stands for Continuous Positive Airway Pressure. CPAP therapy is the most commonly recommended, and the most effective, treatment for obstructive sleep apnea.
A CPAP machine provides air at a constant prescribed pressure. The air is delivered to the person through a tube and a CPAP mask. CPAP therapy provides a constant airflow which keeps the airway open so uninterrupted breathing is maintained during sleep. The air stream eliminates Sleep Apnea events and allows the person to get a restful sleep.
The level of air pressure required to maintain your airway is determined during your sleep study. Your doctor will write a prescription for a CPAP machine set at that pressure.
CPAP therapy is delivered through a nasal mask that seals around the nose or nasal pillows which seal at the nasal opening. Full face masks are available for a person who breathes through both the nose and mouth. Many innovative and comfortable options are available and advances in the delivery of CPAP therapy are continually occurring.
For instance: Some machines offer a comfort feature such as FLEX or EPR technology. It provides exhalation relief, a slight drop in pressure at the time of exhalation to help make therapy more natural. APAP, BiPAP and BiLevel machines offer various levels of pressure throughout the night.
A passover humidifier uses a chamber of room temperature water with the CPAP to add moisture to the airflow and reduce irritation to the nasal passages.
Air flows from the CPAP through a short hose to the humidifier chamber where the air "passes over" the water to pick up whatever moisture it can. The air then flows into the six foot hose to the mask.
Passover humidifiers may provide sufficient moisture with CPAPs set at lower-end pressures. However, if the moisture is not sufficient there is no way to increase the amount of moisture added. Furthermore, because the water is room temperature, in cold climates the water temperature will drop causing the CPAP air to become very cold and the amount of moisture will be reduced
An integrated humidifier is used with a specific CPAP and fits directly onto the machine. This eliminates the need for a second hose, and with most heated humidifiers the need for a second power cord.
The advantages of an integrated humidifier are that it works very closely with the CPAP machine and is a compact unit that uses fewer parts.
A disadvantage is that if it is being used as a passover humidifier it will produce less moisture because the surface area is typically smaller. An integrated humidifier will function only with the CPAP for which it was designed.
You can see if your machine has an integrated humidifier option by reviewing our Compare Charts.
An example of an integrated humidifier is the PR System One Heated Humidifier as seen below attached to a machine in the PR System One line.
A stand alone humidifier is a component that will work with any CPAP and does not attach directly to the machine. It has its own power cord and a short hose is used to connect it to the CPAP. Generally it will sit next to the CPAP machine and is slightly larger than an integrated humidifier.
The advantage of a stand alone humidifier is the fact that it may be used with any CPAP machine.
The main disadvantages are that the size is often larger than either a "built in" or integrated humidifier and that a short hose is needed to connect it to the CPAP machine.
An example of a stand alone humidifier is the Fisher & Paykel HC150 Heated Humidifier as seen below.
Rainout is the accumulation of water in a CPAP tube due to warm moist air cooling and condensating on its way from your CPAP machine to your CPAP mask.
The image below from Fisher & Paykel explains how rainout is formed. Warm moist air leaves the heated humidifier and travels down the CPAP tube. As the air travels down the tube the room temperature cools the tube and thereby cools the air traveling down the tube. As the air cools, it releases its moisture and condensation occurs, otherwise known as rainout.
Solutions to rainout include:
Use distilled water to help keep the humidifier chamber clean and mineral deposit free. Tap water should not be used as it will leave hard white mineral deposits in the chamber as the water evaporates, or it may lead to mold growth. Cases of lung disease have been connected to using contaminated well water in a CPAP humidifier.* Source
If distilled water is not available where you live, use bottled water. It will be important to clean the chamber each morning, do not leave standing water the chamber between uses.
A humidifier prescription must contain all of the following information:
