The Hybernite Rainout Control System enhances sleep therapy comfort by preventing condensation and rainout at the mask and within your CPAP or BiPAP breathing tube. Hybernite doesn't require the latest-and-greatest CPAP machine to work. It is a standalone solution that can be used with any Humidified CPAP or BiPAP machine that accepts standard tubing.

The Hybernite Rainout Control System's medical grade power supply, with plug-and-play simplicity, heats copper wires embedded in the walls of Hybernite Heated Tubing. Hybernite maintains a uniform temperature along the entire length of the breathing tube, regardless of changes in outside air temperature, improving comfort, allowing for increased humidity, preventing rainout, and increasing pressure stability.

In the past CPAP/BiPAP users have been forced to compromise their Sleep Therapy comfort -- by lowering humidity levels -- in order to avoid the noise, discomfort and therapy disturbances caused by rainout. With the Hybernite Rainout Control System you can set your humidifier properly -- to prescribed or desired levels -- and still enjoy a quiet, comfortable, rainout free night.

  • Power Supply - The manufacturer recommends that the Hybernite Power Supply Unit be placed on the floor during operation. If the power supply is disconnected or not available for use Hybernite tubing will function as standard CPAP tubing without power.
  • Humidification Required - The Hybernite Rainout Control System is only compatible with CPAP/BiPAP machines equipped with water based humidifiers. If your system is not equipped with a humidifier then the Hybernite system cannot be used.
  • Hose Wraps & Covers - The manufacturer recommends that Hybernite Heated Tubing NOT be wrapped or covered with a Snuggle hose or any similar product due to the possibility of elevated temperatures.


  • Universally Compatible* - Compatible with ALL Humidifier equipped CPAP/BiPAP systems that use a standard hose and all CPAP/BiPAP masks
  • Say Goodbye to Rainout - Reduces or eliminates condensation and rainout in CPAP/BiPAP masks and tubing
  • Optimal Humidification - With Hybernite there is no need to lower your humidifier's settings to stop rainout! Hybernite does it for you so that you can set your humidifier as high or low as needed for comfortable sleep therapy

This product is a a life changer. I was pouring water out of my tube every night when I would wake up to my mask gurgling... Defeating the purpose of the mask and getting a good night's sleep right? That's what I thought as well so I finally shelled out the money for the Hybernite, and boy I wish I would have done it sooner. Don't delay buy right away and you will never need a life raft in bed again!!!!

An extra boost of heat
Written By: Barb, PSL 12/20/2016
Because of my sinuses, I need to have warmer air than the heated hoses that come with most machines generate. This is my answer.

I love this tubing!
Written By: Elaine, Portland, OR 9/18/2015
I use this and it completely prevents rain out, even with the humidifier set at 5. I still use a hose cozy as I sleep with a fan and the breeze cools the heated tube off enough to keep it from working. I replace it about once a year, and wash it once a month or so, I've never had any problems. I hope they keep making it!

Great - will no longer buy regular hose
Written By: Sharon S, St. Petersburg, FL 5/5/2014
I had bought a Hybernite heated tubing and power supply for my Respironics system one CPAP. I travel with it and of course each different TSA (even in the same city) treats the CPAP differently. Some want everything taken out for examination, some only take out the machine, some don't take anything out at all. Eventually their manhandling was going to break something. The first to break was the hybernite tubing. I had to deal with rainout for a week until I got home and the new one had arrived.

It tore in less than 4 months
Written By: Shoshana D., Fort Lauderdale 12/31/2012
The tubing worked in that I did not have any rainout. However, even when heat was set at OFF the tube was warm which was annoying on a warm night. Off should mean off. Then the tubing tore after less than 4 months. I would have to buy the replacement tube but I am not interested in spending that every 4 months.

Stopped the condensation
Written By: Larry D, Mojave Desert 12/8/2012
I use a cold-pass humidifier after the CPAP machine because the internal heated humidifier was not sufficient in this dry climate. I had to stop using the cold humidifier when the nights were cold enough to cause condensation. The Hybernite system completely eliminated the problem.

No more condensation!
Written By: Ross Bernheim, Sunnyvale, CA 4/16/2012
Simple to set up and use. Stops the condensation and water up the nose. Works like is says it does. Two negatives, plastic smell from outgassing in the tube for the first night or so of use and the hose ends are of a stiffer material than the normal hose ends, but do not pose a problem. I am very happy with the system after using it for a couple of nights.
