This is the company that produces the product being compared.
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.
|2 Years||2 Years||3 Years|
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.
|31 dB||<30 dBA||26.6 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.
|Patient/Quick Setup||Patient||Patient/Quick Setup|
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.
|Under 3 lbs|
This measures only the weight of the machine and does not include total weight of power cables, bag, additional batteries or non-built-in humidifiers.
This is the actual weight of the CPAP Machine without any accessories, power cord, or humidifier. Machines with a weight 3lbs or less are also identified in the Under 3 lbs property.
|2.9 lb||2.8 lbs||0.9 lbs|
This is the combined weight of the machine, heated humidifier, power cables, bag and hose. The weight of the shipping box is not included in the number.
|4.55 lbs||6.8 lbs||4.8 lbs|
This is the combined dimensions of the CPAP with the Heated humidifier.
|12" x 5" x 4"||6.5" x 10.75" x 4"||10.5" x 6.25" x 6"|
|Entire Package Size|
This is the size of the CPAP with Heated Humidifier in its travel bag.
|12" x 15" x 5"||8 " x 14.75" x 8"|
|Machine Size Only|
Measures the overall dimension of the machine only. Machines with a built-in humidifier are marked NA and must refer to Entire Size dimensions.
|4.4" x 6.5" X 5.7"||7" x 5.5" x 4"||6.1" x 3.5" x 2.8"|
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.
|Humidaire 4i||System One 60 Series||Transcend Heated|
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.
Manufacturers are finding ways to reduce the amount of water that collects in the CPAP hose when using a Heated Humidifier. The Rainout Reduction feature varies by manufacturer and machine and can be anything from an integrated heated hose, to technology that measures the humidity at the mask and adjusts the humidity to reduce rainout.
|No||60 Series Heated Tube||No|
|Integrated Heated Hose|
This indicates that the machine has an integrated heated hose option to enhance humidification and reduce rainout. An integrated heated hose draws its power from the machine itself and does not have a separate power cord and is adjusted through the machine settings.
|Humidifier Water Capacity|
This is the maximum water capacity held by the chamber of the compatible humidifier.
|325 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.
|4-20cm H20||4-20cm H2O||4-20cm H2O|
|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.
|EPR CPAP Mode Only||A-Flex||EZEX|
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.
|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 (see _Direct Battery Operation_). This allows you to use a DC power source, such as a battery or car cigarette lighter. Although some cables already come with battery terminal leads, some DC cables will need a separate part that connects the cigarette lighter adapter to another adapter with terminal leads.
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).
|LCD; ALARM||LCD; ALARM||No|
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|
The machine display is lit for ease of reading.
|Backlight Shuts Off|
The backlight for this machine either shuts off automatically after a short intreval or can be set to off.
This machine comes with a 2 Year Manufacturer Warranty. CPAP.com will work with the manufacturer on your behalf if the machine needs repairs. Please follow these steps:
Please note: The manufacturer warranty is voided by water damage or misuse of the machine.
The S8 Series CPAP machines operate automatically between 110v and 240v AC. When traveling either inside or outside the USA, there are no switches to switch or fuses to change. The machine will automatically sense what voltage is needed and set itself to run on that power.
The user will need to adapt the plug that goes into the wall to fit the style of outlet socket that is being used. This is simply done with a Power Adapter Plug kit. This is the same type of plug adapter that would be used with a hair dryer or an electric shaver. World Traveler Power Adapter Plugs.
Battery Power for S8 AutoSet Vantage
ResMed S8 Series CPAP machines come equipped with a DC plug on the back of the unit. This allows the user to connect the CPAP to an external DC battery source. This cord is ideal for travel by recreational vehicle, boat, or any external DC batter that is equipped with a cigarette lighter plug.
The 2.5 lb CPAP.com Battery Pack is surprisingly small and lightweight. The lithium ion battery can be recharged at any discharge level without losing charge time due to battery memory loss. This battery has been approved by the United Nations and Department of Transportation as tested safe for travel. This battery kit comes with the CPAP.com battery and the DC12 Converter for S8 Machines, the cable needed to power most ResMed S8 CPAP machines.
This portable battery pack is an external lead acid battery that is the ultimate in power, portability and convenience. This battery kit comes with the Respironics battery and the DC12 Converter for S8 Machines, the cable needed to power most ResMed S8 CPAP machines.
*Note: This is a battery life estimation based on the battery and the machine. Each machine has unique power needs. Look for the Battery kit that has all the cables needed to safely run your machine. Each battery kit page contains a note about which machines are compatible with that specific battery kit. Please always read the "Important Tips" tab for further information on battery use.
"I am new to CPAP treatment, this is the first CPAP system that I acquire, I ordered the system from outside the US and English is not my native language. Having said that, please, excuse my gramatical and/or orthographic mistakes. I acquired the Resmed S8 Vantage EPR Auto CPAP machine, the H3i Heated humidifier and the Mirage Swift II Nasal Pillow system. My conclusions after 10 days of extensive traveling are:
1.- CPAP.com. Fully reliable. I received more than I expected. Plenty information and data to decide. Ordering process seamless. Customer handling and attendance of prescription filing (even foreign and in language other than English) spotless. Delivery and information about delivery impeccable.Post sale follow up is very well designed. 2.- S8 Vantage EPR Auto CPAP. A beautiful piece of engineering. It provided me the sleep time that I had forgotten from the very first night. Light, compact, easy to operate. Quiet while in operation. Autoadjusting feature is great. Provides comfort and feeling of security. Absolutely no problems with (a) TSA inspections in airports, (b) boarding and traveling in aircrafts (large and regional commercial equipments), (c) airline crew and fellow passengers, (d) US and foreign customs. Automatic adjustment for pressure altitude worked perfect. 3.- H3i heated humidifier. It is wonderful. I used in dry winter weather in PA, humid A/C cooled Florida weather and within pressurized aircrafts and it gave me comfort in my throat and nose as if I had not used a CPAP all night long. Easy to fill up, install and undock. It adds to stability and security. 4.- Mirage Swift II Nasal Pillow system. This system is excellent and remarkably well designed. No more adjectives are necessary. Just one suggestion: watch the DVD and notice the last rotation movement of the frame for perfect seal and comfort."
"I recently ordered the ResMed Vantage Auto after my house burned down and the Respironics RemStar Auto, which I had purchased from CPAP.com only about six months before, was destroyed. I had used a ResMed Sullivan V for about six years prior to purchasing the Respironics machine, so since the RemStar Auto is no longer in production, and since I had read a number of negative reviews on the new M-Series from Respironics, I decided to try the ResMed Vantage Auto. What a mistake!
The one good thing I have to say about the ResMed Vantage is that it's "cute". It's a lot better looking than the boxy black RemStar Auto. That's about its only advantage, though. When I bought the Remstar six months ago, I was very impressed with the exhalation pressure relief feature. Although I had read that the RemStar and Resmed pressure relief systems worked differently, I expected them to give me a similar
level of comfort. Unfortunately, the ResMed doesn't even come close. With the Respironics machine, there was virtually no back pressure on exhalation. With the ResMed, I can't tell you how many times I have gone through the menu to make sure that the feature is even turned on. I can hear a slight change in the motor speed, but it doesn't translate to any significant difference in air pressure. It feels almost exactly the same as the six year old machine I had (which didn't even have a pressure relief feature). And the fact that you can't even use the feature in the Auto mode makes it virtually pointless to buy the Vantage Auto. I really wish that Respironics
was still producing the RemStar Auto, and even with all of the problems I've heard about, I wish I had taken a chance on the Respironics M-Series.
Why would anyone would pay $300 more for the ResMed? I made the mistake of thinking that if it cost more, it must be better. Every night, I kick myself for making that decision. I've never even seen a Respironics M-Series machine, but if they can fix the problems with it, it has got to be better than the ResMed Vantage.
In fairness, I should note that the Vantage Auto (without the humidifier) is really quite small, and since I travel a lot, it may be easier than the Remstar Auto to take with me on trips. And, like I said, it's certainly "cute". If you are interested in style over function, and you like to brag about how much you paid for things, then the ResMed Vantage is definitely the machine for you!!"
"I first tried this machine when my Remstar had to go in for warranty work and this was a loaner. I loved it then for it is so quiet, easy to use, compact, and worked great. My Remstar then bit the dust and was out of warranty, so I needed to purchase a new machine. Lucky for me, this one was on sale and i got a great deal. I have had it for a week and it is great. No regrets and it is quieter than my Remstar ever was. It is a great choice."
"All aspects of the buying process were made easy and I was kept informed by e-mail promptly regarding the ordering, the delivery and the performance. I was pleased with the person taking the order and will surely use this company again for my next purchase, be it major or minor. The machine has exceeded my expectations and would recommend it to all."
"I purchased this Resmed machine although I previously had a Remstar M series machine. This machine is good, although I see some differences between the two. The price however, was excellent albeit it was a closeout as they have a newer model now. I'm still very happy with the one I got."
The S8 Autoset II has EPR, whereas the S8 Vantage does not. Additionally, the S8 Autoset II is 7 db more quiet than the S8 Vantage.
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:
All CPAP masks work with all machines.
We provide our customers with many tools to make informed decisions about their machine purchases. Options include:
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. 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 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 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.
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.
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 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.
CPAP machines which record full data (such as AHI and leak info):
When a physician orders a pressure change, or a patient moves to an area with a very different altitude and does not have an altitude compensating machine, there are a number of ways to ensure you are receiving CPAP therapy at the correct pressure.
Sleep laboratories and sleep disorder centers may be willing to make this pressure change. Just call a big local hospital or ask you physician for sleep lab phone numbers. Be sure to take your prescription.
A second way is to do it yourself. We sell manometers that are very portable, accurate, and simple to use. All the machines we sell come with instructions on how to set pressure to physician orders. Most patients have little trouble doing this themselves. If you need help we can talk you through the procedure.

Fisher and Paykel Water Column CPAP Manometer with HC325 Chamber
A third option is to ship the machine to us with the new prescription. We will set it and ship it back.
It is the law and good common sense to run all sleep disorder devices at the prescribed pressure. If you think your prescribed pressure is wrong, talk to your physician.
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.
Some CPAP users find it more pleasant to breathe with an APAP than with CPAP. The pressure delivered by an APAP machine automatically changes as needed to deliver the minimal pressure required to maintain the airway. The pressure delivered by a CPAP machine is set to a single pressure, the highest necessary to keep the airway open as determined during the sleep study. This is the case even when the higher pressure is needed only a fraction of the time.
An APAP prescription must contain all of the following information:
There are a lot of back up battery choices out there that can give you peace of mind in case of a power outage. The Transcend Travel CPAP Machine has Battery Options available for that can set up as a fail-over, back up battery. Review the "Power" Tab on the machine page.
CPAP.com sells battery packs to accompany your machine if an integrated battery is not available. Visit CPAPtalk for more advice specific to your needs, or view this past thread on the topic here.
