H5i Humidifier

The H5i Humidifier regulates your device's internal temperature and humidity in the midst of changing environmental conditions. ResMed now includes a warm-up indicator with the Humidifier, letting you know how close the heater is to reaching its full temperature.

ClimateLine Tubing(Optional)

The S9 uses ClimateLine Tubing, which has a heated internal coil and mask temperature sensor that eliminates rainout. The system's Climate Control monitors the temperature from the humidifier to prevent condensation from developing.

Continuous Monitoring

The S9 Auto measures your breathing rate all night long, adjusting the device's pressure settings based on your latest breaths to maintain an open airway. The constant monitoring ensures that your breathing stays regulated throughout the night, allowing you to wake up ready to start your day.

Just Breathe

ResMed's SmartStart and SmartStop features let you control the therapeutic process. The device starts when you first breathe into the mask and stops when you pull it off in the morning, making it one of the easiest sleep apnea therapy devices to use in the world.

Breathe Easy

ResMed improves your respiration with its innovative EasyBreathe technology. The machine alters pressure while you inhale and exhale for a smooth, customized breathing experience. The S9 continuously monitors your breathing based on your activity, keeping a continously open airway.


ResMed's Vsync technology monitors the VPAP mask's leak rate throughout the night and self-adjusts the baseline pressure based on its perceived leak rate.

A friend of mine had a near death experience because he had Central Sleep Apnea, which his doctor told him years ago but he never really thought he needs one. One morning he didn't wake up, and his wife tried waking him up but he was just silenced. His family called 911 and when he woke up in the hospital, they found out that his upper airway did not open thus he was “dying” in his sleep. From that day on, he always use his BPAP machine when he is asleep.

As for me, I have CSA also, and I got one BiPAP right away, not wanting to wait like my friend did. My doctor prescribed me a this S9 VPAP Auto machine, that has the climateline tubing included so there is no moisture collected in the tube and transfer it to my mask. Not pleasant to find out your mask is full of water the first thing in the morning.

At first I thought I could use the S9 AUTOSET, since it has two levels of pressure settings, however, that is not the case. The Auto CPAP one can only delivers pressure within a prescribed range, for example, 8 cm of water and 16 cm of water which has a difference of 8cm of water from the minimum to maximum pressure. And that it constantly adjusts to the minimum pressure.
Whereas the BiPAP machine has two set pressures, one is for EPAP (min. pressure) and one for IPAP (max. pressure), and a pressure support threshold of 3-6cm of water. The S9 VPAP Auto best suited me for my condition, since it is very quiet and a smooth transition from my inhalation pressures to my exhalation pressures. This machine also has the ability to give a snapshot of my data that I can view right on the screen of the machine. Anyway, ever since I started using this machine, my health has improved greatly! It has a lot of features to set to your comfort needs.

Best machine on the market. I swear by it. Everyone I have told about this machine has ended up ordering one or getting one through their insurance company's. I would be dead with out mine. It is very easy to clean and take apart. It also does not look to bad when you have to travel with it. Looks pretty much like you are carrying a laptop instead of a clunky medical device. The ResMed Swift™ FX CPAP Nasal Pillows System & Headgear is the perfect fit. I could not use this mask with my cpap but once I switched to the auto vpap I could. It was the perfect combo best night sleep ever.

Please bring this wonderful machine back into circulation!
It is simple, straightforward, and just PERFECT.
I have used mine for five years, so was told that I am eligible for a new machine.
However, I was sent an S10 which is DO NOT LIKE!!.
The design of the S10 is terrible. The water chamber does not come out easily,
and it does not separate into two parts to drain.
The happy faces and gee-gaws are unnecessary.
I sent the S10 back.
All I want is another S9 PLEASE!!!!!

I like this machine very much because of its size. It's the state of the art machine. One thing about it is it tends to increase pressure too fast when it detects events like snoring, flow limitations and clusters of OAs and Hs, and triggers leaks, which wakes me up from a good sleep.

This machine is great. I was able to use the first night, all night... The price charged on this site is a bargain. My insurance company was billed more than twice the cost of the machine sold here. The unit is quiet, easy to use and light weight.

I've had my ResMed S9 for two years now. The unit is very quiet and easy to clean. I take it camping with us to help me get a good nights sleep. It is nice to wake up rested and refreshed. I can't imagine sleeping without it.
