Until very recently the benefits of humidification in CPAP therapy have been compromised by changing ambient temperature. Changes in temperature cause condensation and mask pressure instability in addition to humidity loss in therapy. As the air travels from conventional heated humidifiers to you via your hose, heat and moisture are lost due to the temperature of the hose and the air around it. This may result in rainout, or simply a compromised humidity level in the air that is traveling through the hose.
ThermoSmart Technology, with its heated breathing tube adapted from sophisticated intensive care humidification, delivers higher and customized humidity levels that are maintained throughout the night, regardless of ambient temperature change. ThermoSmart Technology provides optimal patient comfort and therapy effectiveness through prevention of condensation and absolute mask pressure stability, but also through optimal humidity delivery in all environments.
Research has shown that CPAP users experience mouth leak up to 31% of total sleep time. Mouth leak is known to cause excessive drying of the nasal mucosa and congestion due to increased nasal airway resistance. Humidity levels of 30mg/L (absolute) at 30°C have shown to prevent any increase in nasal airway resistance following a mouth leak.
Conventional humidifiers are unable to supply these levels. Typical conventional humidifier will only provide humidity levels of approximately 18mg/L (absolute) at 22°C. Any efforts to increase this will only result in condensation.
Currently, optimal humidity delivery is only possible with ThermoSmart Technology. It results in optimal sleep performance due to higher comfort levels leading to improved patient acceptance and compliance.

These 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.
Respironics Battery Kit with 400 Watt DC to AC Power Inverter.
This battery kit comes with an external 400 Watt DC to AC power inverter for CPAP and BiPAP machines. The kit provides AC power for machines that do not come with a DC input. Use your machine's AC cord to connect to the power inverter. The Respironics 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 400 Watt DC to AC Power Inverter.
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.

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.
This machine was an excellant choice. The only down side is the water chambers. They can not be disassembled for a propery cleaning. I'd reccomend the upgraded chamber, but you'd probably have to call that in when ordering.
The machine itself is an excellent choice. It is quiet and easy to set up. The only comment I have is: I have troouble removing the resevoir on the front. It is kind of hard to remove, but to put it in is a breeze. The funnel makes it easy to refill.
Excellent. I have one that I travel with and this one is for home. I have had the airlines lose my original one for several days at a time, so I bought this one to keep at home. Thanks for your help.
Machine is quite good and completely eliminated the gurgling hose. It would be nice if instructions more clearly identified humidifier setting and hose heat controls. For improvement I would like to see more humidifier capacity and a lower hose temp setting available. Filling integral reservoir is a pain. I would like to see a fill spout I could insert a funnel in without removing the reservoir from the machine.
This SleepStyle 604 is my second Pisher & Paykel CPAP. My SleepStyle 200 has worked beautifully for five years and it will be my travel CPAP. I upgraded to the heated hose and ThermoSmart humidifier to eliminate the annoyance of rain out. Hopefully, I will not be awakened a few times nightly to empty the condensed water from the hose on humid nights. I did not get the SleepStyle 608 with automatic altitude adjustment since my home CPAP will remain at sea level.
Very good result
Excellent I am very satisfied
well made easy to use
I have used two barands of cpap machines & found this one that I am using (604 Thermosmart CPAP Machine)to be the machine that has given me the best nights of uninterupted sleep.The reasons being, 1.Quiet running, 2.The thermosmart comfort humidity control. I reccomend this machine highly to any cpap user if they also want to have better nights of uninterupted sleep.
Works just as described.Canada post is a little slow at there delivery end and they are no help in tracking the order
I have been using an older machine for years and recently upgraded to the HC604 and love it. The heated humidifier makes all the difference in the world when it comes to your sinues drying out.
I got this for its stronger humidifier, and the non-condensing heated hose. It can use 2x as much water in a night as the respironics for greater comfort. I have used this with a $69 computer UPS (batt backed power). It works fine, but uses batt power faster than respironics depending on humid setting. Getting this thing to turn on and off is tricky, there is a long delay on startup. I have to watch the display to get it on. The sound has some rumble to it, I sometimes think a jet is flying overhead. Try to let this hose blow out a few days (at least during the day) because it really stinks of plastic. Even the humidifier tub has some plastic smell at higher humidity settings, even when using my old hose (I can barely stretch the fitting of 14mm Respironics over the larger output). I am spoiled by my Respironics having a loose-mask alarm and leak compensation that I consider safety features, but I adapted by tightening my mask straps.
