If you are being awakened in the middle of the night feeling water droplets splashing your face while using your CPAP machine, you are likely experiencing what’s called CPAP rainout. This is a common phenomenon for many CPAP users, and they often ask the question Why does my cpap mask get water in it? This common issue not only disrupts sleep but also affects your comfort and adherence to treatment. In This article, we’ll explain what rainout is, why it happen and most importantly how to stop water in CPAP mask?
What is rainout? Is CPAP rainout dangerous?
Rainout occurs when moisture from your CPAP humidifier condense inside your tubing or mask. This phenomenon occurs due to the use of a heated humidifier, the difference in warm, moist air moving through the duct cools down before reaching your mask. This condensation can lead to water droplets in CPAP mask, making it uncomfortable to breathe and potentially causing you to remove your mask during the night.
Over time, if the water remains in your mask or tubing, it could lead to skin irritation, discomfort or even bacterial or mold growth if not cleaned properly.
Although not dangerous, CPAP rainout affects the effectiveness of treating sleep apnea. Therefore, cleaning and maintaining CPAP equipment is an important part of the usage process.
Causes CPAP rainout
The main reason leading to common CPAP rainout is:
Due to the use of a heated humidifier
One of the most common causes of CPAP machine water in mask is the humidifier. Most modern CPAP machines include a heated humidifier which adds moisture to the air to keep your nose, mouth and throat from drying out during therapy. However, when this humid air cools too quickly as it moves through the CPAP tube, condensation will occur.
Think of it like that a cold soda can on a hot day moisture from the air turns into droplets on the surface. This same process happen inside your CPAP hose and mask.
Room temperature and climate
The temperature of your room also plays a significant role in rainout. If the room is too cold or if there are cold air drafts, air conditioner running, the moisture inside the hose will condense before reaching your mask.
Symptoms of too much humidity in CPA:
-
Too much water in CPAP mask only after a few hours of use.
-
A gurgling sound in your CPAP tubing caused by water collecting in low spots.
-
The damp feeling inside the mask cushion makes it slippery.
-
Waking up with water splashing your face or dripping near your nose.
In some cases, excessive humidity can also cause shortness of breath, forcing you to remove the mask before dawn.

Signs of CPAP rainout even with heated hose
Many CPAP users switch to using heated tubing to help prevent condensation by keeping the air warm as it moves through the tube. However, even with heated tubing, rainout can still occur. Some of the reasons for this are:
-
Water in CPAP hose and mask despite having heated tubing.
-
Temperature differences between your bedroom and the inside of the hose
-
Moisture accumulates in some bends or depressions in the pipe.
Although the solution using thermal tubes is effective, it is not the perfect solution; we need a more advanced optimal method.
How to stop water in CPAP mask?
If you are tired of constantly asking "Why does my cpap mask get water in it?", it's time to put an end to this issue. Here are some proven methods to prevent this condition from occurring when using CPAP devices, ensuring comfortable sleep.
Use Heated Tubing
One of the measures recommended by many units is to use a heater. The thermal coils inside the tube help keep the air warm as it travels from the humidifier to the mask, reducing the likelihood of water droplet formation.
If you have been using the heater for a while or sometimes still see water in the CPAP tube and mask. Check your hose temperature setting, raising them slightly can make a big difference. Also, inspect your heated hose for any sign of wear or damage as these can reduce its effectiveness.
Adjust the Humidifier Setting
Reducing the humidity setting can help prevent excessive moisture buildup in the CPAP mask. It’s not necessary to turn off the humidifier entirely, just adjust the level so that air remains comfortable but not too saturated.
In the market, some CPAP devices have the feature of automatically adjusting humidity according to changes in room temperature, helping to prevent water from overflowing into the CPAP mask. It is suggested that you look for purchases at reputable distributors that offer warranties. Try switching to a lower humidity setting to see if it resolves the issue.
Change the Ambient Temperature
The room temperature plays an important role in preventing the phenomenon of CPAP rainout. If the temperature in the bedroom is too cold, the humidity in the tube will condense into water droplets in the CPAP mask. To prevent this, try:
-
IAdjust the bedroom temperature appropriately, recommended at a temperature between 25-27 degrees.
-
Use a heater to create a stable temperature around the CPAP machine.
-
Make sure your CPAP machine is placed away from cold drafts, windows, or air conditioning units.
A warmer environment will help prevent water in CPAP hose and mask by reducing the temperature difference between the most air and the room air.
Adjust the Position of the Machine
The placement of the CPAP machine is also an important issue to pay attention to. If the machine is placed at head level or higher, condensation is more likely to accumulate in the tube.
To fix the phenomenon of water accumulation in the mask and tubing, you should place the CPAP machine lower than the head of the bed. This simple adjustment leverages gravity to ensure moisture that form in the tubing drain back into the humidifier, preventing it from pooling uncomfortably in your mask.
Wrap the Hose
An effective and cost-saving method is to use CPAP tube covers. The insulation layer of the casing will keep the temperature of the airflow stable throughout the process of moving through the pipe, thereby significantly reducing the risk of condensation. You can buy a dedicated tube cover or simply wrap the hose with a soft fabric to achieve a similar result.
The pipe insulation not only helps prevent water accumulation but also ensures that the airflow is maintained steadily. This helps prevent the sudden cooling of the air, thereby improving the quality of your sleep.
FAQs:
Why is my cpap machine leaking water underneath?
If notice water leaking from the bottom of CPAP machine, the problem is usually with the humidifier chamber. The 2 most common reasons for this are a cracked chamber and on that’s been overfilled.
Therefore, always pour water into the chamber up to the marked line and check for any damage before use. Any excess water can overflow, causing leaks that can damage equipment over time.
Why does my cpap mask get water in it?
This question has been explained in detail in the content of the article. In summary, the main cause is the condensation of moisture from the humidifier cooling before reaching the mask, creating water droplets. Environmental factors such as bedroom temperature, humidifier settings, and the sleep position of the duct all play an important role in improving this condition.
How do I dry out my CPAP mask?
Drying your mask is easy. Follow these simple steps:
-
Remove the CPAP mask from the hose.
-
Air dry naturally in a well ventilated area
-
Wipe with a clean, dry cloth or paper towel to absorb any remaining water droplets
-
Use a cool setting on the dryer or use a fan to dry.
Can i use my CPAP without a humidifier to avoid rainout?
Yes, you can. But turning off the humidifier can lead to an uncomfortable, dry experience, including a dry mouth, nose and sore throat.
It is better to adjust the humidifier settings to a lower level rather than turning it off completely. Most CPAP users find that low to medium humidity settings are still effective and prevent too much water in the CPAP mask while keeping the air comfortable.
