The best way to avoid water in your CPAP hose and mask is by trying to closely match the temperature inside and outside of your tubing, but sometimes that isn’t enough to prevent CPAP rainout. You may have to incorporate a hose cover or adjust your CPAP humidifier settings to prevent water from collecting in CPAP hose.
Solutions for Rainout
Sleep disruptions from CPAP tubing gurgling or CPAP machine rainout can cause you to feel tired the next day, even if you were in bed for a full eight hours. With sleep apnea, it’s important to set yourself up to get the best sleep possible—and that includes preventing rainout.
Here are six impactful things you can try for a more peaceful night:
Use Heated CPAP Tubing
Made to manage humidification in real-time based on the ambient temperature levels of your bedroom, heated tubing helps reduce CPAP rainout by keeping the temperature of the air consistent as it travels from the humidifier to your mask.
Many popular CPAP manufacturers offer heated tubing options for their equipment, like the ClimateLineAir Heated Tube for the AirSense 10 and AirCurve 10 machines and the Heated Tube for any DreamStation machine. One of the best CPAP hose options available is the non-condensing ClimateLineAir, as it helps prevent rainout and permits movement while you snooze.
Wrap Your Hose to Keep Air Warm
Additionally, wrapping your CPAP hose with a specially-designed tube cover helps insulate the hose and blocks the ambient temperature of your bedroom from causing CPAP rainout. As an added bonus, you can run the tubing underneath your bed covers to provide additional warmth for the hose. Ultimately, having the right CPAP hose accessories go a long way in preventing CPAP rainout and helping you stay asleep.
Adjust the Ambient Temperature
As mentioned, the difference between the temperature of the air in your tubing and the temperature of your bedroom is what creates CPAP rainout. If you keep your room extra cold at night, you’re more likely to experience condensation in your tubing. This is a quick and simple fix, but many people enjoy sleeping in cooler rooms so you may want to adjust the humidifier settings instead.
Adjust Humidifier Settings
The right CPAP humidifier settings can make all the difference. In general, the best humidity level for CPAP machines is a setting of three. To help address CPAP rainout issues, you can adjust the settings by 0.5 increments, but visit with your doctor first. Before changing your humidifier settings, talk to your equipment provider to help discover your best temperature setting for CPAP therapy.
Look for Machines with Automated Adjustments
Most insurance companies will replace your CPAP mask after 90 days and your CPAP machine every five years. A lot can change in five years, including technology upgrades and smart functionality that make your sleep apnea journey more comfortable.
The S1 CPAP machines from SVPAST, for example, feature automated adjustments designed to maintain humidity levels. This special climate control feature constantly monitors the temperature of the air in your mask and how it is affected by ambient temperature. As needed, it simultaneously adjust tubing levels, providing an optimal temperature that helps prevent CPAP rainout.
Move Your CPAP Machine
Make gravity work for you! Place your CPAP machine at a lower level than your mask so condensation can’t flow to your mask while you sleep. If your CPAP equipment is currently on your nightstand, try moving it to a lower shelf—or even the floor. Any water droplets that do form will flow back into the humidifier instead of sprinkling across your face.
Final Thoughts
Even when treated with the proper CPAP equipment, having sleep apnea can make it challenging to get quality sleep each night. Some experience bloating and some experience skin irritation, but it’s important to maintain compliance since untreated sleep apnea can lead to serious complications.

Overall, many people with sleep apnea believe the benefits of using moisture in conjunction with their CPAP equipment outweigh the potential for CPAP rainout, especially since there are steps you can take to mitigate middle-of-the-night disruptions.
