Learn More About Your New Machine

The REMstar Auto M Series with A-Flex represents an amazing new chapter in pressure therapy. Not only does it make each breath more comfortable at inhalation and exhalation, the REMstar Auto also adjusts overall therapy to accommodate the patients therapy needs due to changes in lifestyle or progression of disease state.

A-Flex is delivered by our clinically proven auto algorithm that maintains effective therapy at minimal pressures making this combination even better for patients.

A-Flex is a comfort feature built on top of the REMstar Auto algorithm. If breathing events occur, the auto algorithm raises the A-Flex pressure profile to eliminate those events, while simultaneously making sure that pressure never rises to a level that is unnecessarily or uncomfortably high.

Universal Power

This system operates 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.

Universal 12 Volt DC Power Cord

This machine 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. The IntelliPAP can be powered by plugging the 12volt DC Power Cord into a cigarette lighter plug. This is ideal for traveling by car, boat, or recreational vehicle that is equipped with a cigarette lighter plug.

Freedom Travel Battery

The Freedom Travel CPAP Battery is currently the best battery on the market to power your M Series machine. It makes a native connection without needing to buy an inverter or extra equipment to make it work.

CPAP.com Battery Kit with Universal 12 Volt DC Cable

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 12 Volt DC Power Cord.

Respironics Battery Kit with Universal 12 Volt DC Cable

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 12 Volt DC Power Cord (connects CPAP to cigarette lighter socket).
What does CPAP therapy do?
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.
Which CPAP masks work on which machines?

Any mask will work with any machine, with one important exception. The ResMed AirMini is only compatible with certain ResMed CPAP masks. Compatible masks for the AirMini are as follows:

  • ResMed AirFit™ N20 Nasal Mask
  • ResMed AirFit™ F20 Full Face
  • ResMed AirTouch™ F20 Full Face
  • ResMed AirFit™ P10 Nasal Pillow

When considering another CPAP, APAP or BiPAP machine from ResMed or any other manufacturer, mask compatibility extends to all brands. The AirMini uses non-standard tubing to connect the machine to the mask, and is the primary reason why other masks won't work with the AirMini. Despite this issue, many of our customers consider the AirMini to be an excellent machine.

What comes with my machine?
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, APAP, and BiPAP 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.

Do all CPAPs use filters?
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.
What is exhalation relief?
Exhalation relief is a comfort feature which reduces the air flow at the time of exhalation, making the breathing process more natural.

The following are the different types of exhalation relief names by manufacturer.

  • Philips Respironics = C-Flex, C-Flex+, A-Flex and Bi-Flex
  • Resmed = EPR (Expiratory Pressure Relief)
  • 3B Medical = RESlex
  • Apex Medical = PVA (Pressure Variation Algorithm) Pressure Relief
  • Curative Medical = EUT (Expiratory Unloading Technology)
  • DeVilbiss = SmartFlex
  • Fisher & Paykel = SensAwake Technology
  • Human Design Medical = Z-Breathe
  • Somnetics = EZEX

Here are some machines with an exhalation relief feature:

Transcend Auto miniCPAP™ Machine with EZEX
PR System One REMStar 60 Series Auto with Bluetooth
AirSense™ 10 AutoSet CPAP Machine with HumidAir™ Heated Humidifier
+ See More
What is A-Flex?
A-Flex is a form of exhalation relief which helps the air pressure from an APAP machine mirror a person's breathing. Like C-Flex, A-Flex provides flow-based pressure relief at the beginning of exhalation. Like Bi-Flex, A-Flex softens the pressure transition from inhalation to exhalation to provide additional comfort in an auto-CPAP mode.

An example of a machine with A-Flex is the PR System One REMStar 60 Series Auto with Bluetooth.

What maintenance is required on machines?
The only care a CPAP, APAP 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.

Here are some other suggested actions to care for your machine:
  • Keep the area around your machine clean by removing any dust from the area to improve the air quality delivered to your machine and to you.
  • Keep the air intake of the machine unblocked. Curtains, bedding, and papers can easily block the air intake of your machine, reducing the airflow.
  • If a humidifier is used with your therapy, do not pick up the machine with the humidifier attached. With most machines it is easy to spill water from the humidifier chamber into the machine causing damage. Manufacturer warranties are voided by water damage to the machine. To avoid this, remove the chamber from the humidifier and then remove the humidifier from the machine rather than transporting them together.
  • If a humidifier is used, empty the water from the chamber every morning. Accidents happen. If a family pet or family member moves the machine and humidifier with water in the chamber it is more likely that water could be spilled into your machine. Water damage to a machine voids the manufacturer warranty.
Why might I prefer an APAP machine?
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.

CPAP Purchase

Verified purchase | Jun. 30, 2010 | Verified CPAP.com Customer
I am very happy to own the Respironics M Series Auto CPAP w/ Aflex. I looked everywhere on the web and the item is currently unavailable in fact my unit was shipped at the same time as the item was taken off the CPAP.COM web site listed as discontinued. This CPAP works for me and is the same model as what I already have. However it was only while doing my research that I found out I was not utilizing the unit in Auto/Aflex modes. I immediately noticed an increase in energy and restfullness at night.

Excelent way to buy all your CPAP stuff. They deliver on time (i chose next day deliver) and the staff was so kindly to speak slowly and understand me with some issues I had. I bought using my brazilian credit card and had it delivered to a friend of mine who lives in Florida. I dont know how does it work to deliver overseas. Thank you CPAP.COM. Excelente maneira de comprar tudo o que voce precisa de CPAP. A entrega foi rapida (comprei com entregar para o dia seguinte) e o pessoal foi compreensivo e falou devagar quando liguei sobre alguns problemas que eu tive com meu cartao. Comprei com meu cartao brasileiro e pedi para entregar a um amigo que mora na Florida. Nao sei como funcionarios para entregar em outros paises. Obrigado a equipe da CPAP.COM.

Verified purchase | May. 18, 2010 | Verified CPAP.com Customer
THIS IS THE QUIETEST MACHINE I HAVE EVER OWNED. ANY MACHINE WILL GIVE YOU AIR SOUND BUT APART FROM THAT THE A-FLEX IS GREAT. THEY SHOULD HAVE HAD A TIMER THAT TURNS OFF THE LIGHTS ON THE BUTTONS. I GUESS THAT WILL HAPPEN ON THE NEXT MACHINE. THE SIZE IS GREAT FOR TRAVEL.

I love this new unit. It may be a little noisier than a traditional CPAP, but the difference made by A-Flex is well worth it. I highly recommend this unit.
