Going to greater depths to improve patient compliance, Respironics developed an integrated, easy-to-use heated humidification system.
The easy-to-set-up REMstar Heated Humidifier offers:
Unique, tubeless design that works with the Legacy REMstar family except for the Remstar Lite. Its simple rubber coupler connection provides secure contact between the water chamber and the CPAP.
Clear, two-piece water chamber that's easy to fill and is dishwasher safe.
A lighted humidifier control button on the CPAP unit makes adjusting humidification levels easy.
Heater plate status light makes it easy to see when the humidifier is on or off.
The Heated Humidifier plugs directly into the REMstar - so there is only one plug going from the CPAP to the wall outlet.

Here is a list of the machines that this heated humidifier works with:
"After using the Remstar AutoPap for a few years, I then found out about the heated humidifier. I ordered one from CPAP.com approximately 4 years ago. I have used it daily since. I noticed a small rusting spot starting to appear, so I ordered another replacement chamber. Since I have two Remstar AutoCpap's and one with C-Flex; and I go camping and boating a lot, I decided to get another humidifer; so that I could have one as a travel Cpap all inclusive and another for just the stay at home station.
I absolutely love all of the Remstar products; and am tempted to buy a travel sized CPAP; but am afraid to invest the money, as I am afraid I will not enjoy it as much as the Remstar Auto CPAP and the wonderful humidifier.
Great Products. Have been on CPAP for 12 years, and am at a 17 mean; and I love your products.

Its better than a bloody nose
Anonymous – March 04, 2008
"Cold, dry winters and hot, dry summers... my nose would never survive without a humidifier. This one works, but I miss the old style water chamber. The new one has a flap in it that tends to stay open when you turn on your CPAP."
"I moved up to a heated humidifier and am very pleased with its performance. Easy to fill and maintain."
No Power Cord
David K, AK – April 27, 2013
"The REMstar heated hunidifier has worked exceptionally well for me for over ten years. I sensed the heating unit was failing and was happy to see the item was carried and in stock. The unit came with a new water tank but I was disappointed in that it did not come with a power cord. Over time the two prong cord has become loose and I assumed a new heating unit would come with a new power cord. So now the search begins."
A heated humidifier uses heat to warm the water to add moisture to the airstream. The heat is adjustable for more or less moisture. The water chamber for a heated humidifier is much smaller than a passover humidifier.
In our considerable experience of specializing in CPAP equipment we have found that patients who use a heated humidifier have a much higher rate of effectiveness to their CPAP therapy.
There are three types of heated humidifiers:
Stand Alone Humidifiers
Built In Humidifiers
What is a passover humidifier?
A passover humidifier uses a chamber of room temperature water with the CPAP to add moisture to the airflow and reduce irritation to the nasal passages.
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. Furthermore, because the water is room temperature, in cold climates the water temperature will drop causing the CPAP air to become very cold and the amount of moisture will be reduced
What is an integrated humidifier?
An integrated humidifier is used with a specific CPAP and fits directly onto the machine. This eliminates the need for a second hose, and with most heated humidifiers the need for a second power cord.
The advantages of an integrated humidifier are that it works very closely with the CPAP machine and is a compact unit that uses fewer parts.
A disadvantage is that if it is being used as a passover humidifier it will produce less moisture because the surface area is typically smaller. An integrated humidifier will function only with the CPAP for which it was designed.
You can see if your machine has an integrated humidifier option by reviewing our Compare Charts.
A "built in" humidifier is designed as a part of the CPAP machine and cannot be removed or separated from the CPAP machine. As with an integrted humidifier, it eliminates the need for a second hose or power cord. The water chamber can be removed for cleaning or replacement purposes.
The advantage of a "built in" humidifier is it makes for a more compact unit with fewer parts. This design also helps to ensure therapy effectiveness by including the heated humidifier with the CPAP machine thereby providing comfort to the CPAP user.
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.
A stand alone humidifier is a component that will work with any CPAP and does not attach directly to the machine. It has its own power cord and a short hose is used to connect it to the CPAP. Generally it will sit next to the CPAP machine and is slightly larger than an integrated 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.
Rainout is the accumulation of water in a CPAP tube due to warm moist air cooling and condensating on its way from your CPAP machine to your CPAP mask.
The image below from Fisher & Paykel explains how rainout is formed. Warm moist air leaves the heated humidifier and travels down the CPAP tube. As the air travels down the tube the room temperature can cool the tube and therefore cool the air traveling down the tube. As the air cools, it releases its moisture and condensation occurs, otherwise known as rainout.
Solutions to rainout include:
Raising the temperature of your bedroom.
Keep your CPAP machine at the same level as your bed.
Insulating your tubing with a hose cover like Snugglehose.
Reduce the tempurature setting on your heated humidifier.
Purchasing 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 mask reducing the occurrence of rainout. The list of available heated hoses can be found here: Hoses With Heating Coils.
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.
Why do I need to use distilled water with in my humidifier chamber?
Use distilled water to help keep the humidifier chamber clean and mineral deposit free. Tap water should not be used as it will leave hard white mineral deposits in the chamber as the water evaporates, or it may lead to mold growth. Cases of lung disease have been connected to using contaminated well water in a CPAP humidifier.* Source
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 the chamber between uses.
