In our experience, it is common for CPAP users to report that their therapy is greatly enhanced by the use of a heated humidifier.
There are three types of heated humidifiers:
- Stand Alone Humidifiers
Stand Alone Humidifiers can be used with almost any machine as long as an integrated humidifier is not being used and the machine does NOT have a built in humidifier. The Fisher & Paykel HC150 Heated Humidifier With Hose, 2 Chambers and Stand is a stand alone heated humidifier that includes ambient tracking to keep the humidity consistent independent of room temperature.
- Integrated Humidifiers
Integrated Humidifiers connect directly to the machine the humidifier was made to be used with. This provides the convenience of being able to remove the humidifier from the machine for traveling or other purposes. Here are some of the integrated humidifiers we carry:
PR System One 60 Series Heated Tube Humidifier with Heated Tube
Transcend Heated Humidifier
XT Heated Humidifier
- Built In Humidifiers
Built In Humidifiers are permanently affixed to their machine and cannot be removed. The chamber can still be removed for cleaning, however the heating element is a part of the machine. The advantage of built in humidifiers is they generally take up less space than a machine with an integrated or stand alone humidifier. Here are some machines that have a built in humidifier:
AirSense™ 10 AutoSet CPAP Machine with HumidAir™ Heated Humidifier
ICON Auto CPAP Machine with Built-In Heated Humidifier and ThermoSmart Heated Hose
iCH Auto CPAP Machine with PVA and Built-In Heated Humidifier
+ See More
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. The water is room temperature. In cold climates, the water temperature will drop causing the CPAP air to become very cold, and causing the amount of moisture to be reduced.
An advantage of an integrated humidifier is that it works very closely with the CPAP machine to deliver humidification. Also, an integrated humidifier is a compact unit that uses fewer parts to provide moisture to the user.
A disadvantage of the integrated humidifier is the user will receive less moisture when it is used with a passover humidifier. The smaller surface area effects the amount of moisture produced. Also, a integrated humidifier will only function 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.
Here are some of the integrated humidifiers we carry:
DreamStation Heated Humidifier
Transcend Heated Humidifier
IntelliPAP 2 Heated Humidifier with Pulse Dose Humidification
PR System One 60 Series Heated Tube Humidifier with Heated Tube
The advantage of a "built-in" humidifier is its compact shape, which operates on fewer parts. This integrated design helps to ensure optimum moisturized comfort and effectiveness when CPAP therapy and humidification are used together. Also, it allows an option for the humidification to be turned off while the CPAP is blowing.
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.
Here are some other machines we carry with built-in humidifiers:
AirSense™ 10 CPAP Machine with HumidAir™ Heated Humidifier
AirSense™ 10 AutoSet CPAP Machine with HumidAir™ Heated Humidifier
iCH Auto CPAP Machine with PVA and Built-In Heated 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.
The image below from Fisher & Paykel explains how rainout is formed. Warm, moist air leaves the heated humidifier and travels through the CPAP tube. As air flows through the tube, the temperature of the room causes the tube to cool. As the tube cools, the air inside releases its moisture, and creates condensation in the hose.
Solutions to rainout include:
- Raise the temperature of your bedroom.
- Keep your CPAP machine at the same level as your bed.
- Insulate your tubing with a hose cover like Snugglehose.
- Reduce the temperature setting on your heated humidifier.
- Purchase a CPAP machine with a rainout reduction comfort feature.
- Some machine systems offer a compatible heated CPAP hose which maintains the temperature from the machine all the way to the mask, reducing the occurrence of rainout. The list of available heated hoses can be found here: Hoses With Heating Coils.
- If your machines uses a standard hose, consider the Hybernite Heated Rainout Control System.
To care for your humidifier simply empty and clean the water tank each morning. Only distilled water should be used in the humidifier to avoid mineral deposit build up. 
Here are some items that can help with caring for your humidifier:
CleanSmart CPAP Disinfectant Spray
Control III Disinfectant CPAP Cleaning Solution - 16 oz Concentrate
Control III Disinfectant CPAP Cleaning Solution - Home Care Kit
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 in the chamber between uses.

Fantastic. Works for about 2-3 nights before you need to refill.
Easy to fill, replace use and clean. The humidified air makes all the difference in preventing dry mouth, throat... and nasal passages in the morning. I've used CPAP for years, but this is my first humidifier. I'll never sleep without one again! more...
fits into the CPAP easily. Easy to fill and clean. Very nice unit.
Not enough water to last 8 hrs.
I love the CPAP + humidifier combo - they are great for travel! The humidifier is a little small;... it is dry before morning, and a bit awkward to refill. I think that's the price you pay for such a compact and travel-friendly unit. more...
Took this little unit on a short trip to test it out for a European vacation in the fall. ... VERY pleased with the ease of packing it up, light weight, and handy carry case (size of a camera case). Had no problems with attaching the humidifier to the unit. As with all units, you can never get the last drops of water out, but not a problem. Quiet, light weight, it is going to work out wonderfully for my trip. more...
This is my second humidifier for the Everest 2. The first one lasted about a year, including a good... deal of foreign travel. I think the weak link is the small electric pad that the water tray connects with - it gets dirty, is hard to clean anyway, and ultimately fails. The water capacity is much less than my RemStar Pro but I expected that in a travel CPAP. Nonetheless, I have to put the heater on a low number to ensure the water will last through the night. The CPAP is a constant pressure model and does not "breathe" with you as does the RemStar. I find I can transition to either one without difficulty. I like the relatively light weight too. more...
This humidifier couples directly to the Everest 2 CPAP machine and the humidifier tray removes easily for cleaning and refill.... I use it every night. Only problem I have had with the unit is that the plastic lid on the humidifier tray has very easily broken plastic snaps that keep the lid connected to the lower tray. Once these snaps get broken, the tray leaks water around the edges. I had to order a replacement humidifier when my first unit got broken this way during a trip. When unit is unbroken, it works fine, but these plastic latches could be improved. more...
I purchased the AEIOmed for traveling. The humidifier is not as easy to use or clean as my REMstar's... unit. Filling requires the removal of the hose from the machine and is filled through the hose connection on the top of the unit. Taking the humidifier apart is also difficult and I felt at times like I could easily crack the plastic. The base can not be submerged so I didn't feel like I could clean it thoroughly. These are minor issues and the design of the AEIOmed is excellent and it's small footprint makes it very convenient for traveling. Time will tell how the humidifier will wear after multiple cleanings. more...
A heated humidifier is a must when using it in the cold north of Alaska. It is also great... in the dry desert of Idaho. I wish it would hold more water as it must be filled every evening before going to sleep. I haven't experienced any problems with the humidifier attachment for the AEIO Everest 2. I also bought the battery pack when I purchased the machine and humidifier. Since this machine works so well, I will be buying a second complete pack to leave at my work site in Alaska. more...
Unit fits tightly, works as expected and I no longer have an occasional leak.
The humidifier is small and easily goes into the unit. It ia also easy to clean. The only improvement is... the opening is small which requires you to use a small funnel or to take the plastic cover off to fill the reservoir. A small adaptor would be nice. more...
