Yes it is normal. The CPAP machine optimizes the humidity level based on the level of humidity in the room. The higher the humidity level in the room, less water will be used. The more dryness in the room, the higher the amount of water will be used.

Set your humidifier to the highest level, usually 5 or 6, let your CPAP machine work for a few minutes. Being very careful not to burn yourself, remove the water chamber. Touch the metal plate placed inside your machine; if it’s hot the humidifier is working.

Humidity is the key to solving this issue. CPAP machines have humidifiers which moisten the air so it doesn’t dry out the nose or throat. You can adjust the level of humidity on your machine. The levels of humidity are 1 through 5, 6 or 8 (different models) with 1 being the lowest level of humidity and 8 the highest. If you have a dry mouth, sore throat or stuffy nose, go higher in number.

If water collecting in the tube or mask is an issue, turn down your humidity or go lower in number.

There is a normal ‘break in’ period with these mask, as the skin around your nostrils and the nostrils adjust  to something resting against them every night. It shouldn’t last more than a week and using Polysporin and Secaris can help. Use Polysporin in your nose in the morning and Secaris at night before putting your mask on. If discomfort persists, it may be time to try a different mask.
