I have a whole house humidifier that keeps the house at a constant humidity level. The temperature in my room was the same as it's been all month. My mattress is higher than the machine.
Shortly after starting to use my bipap last night, I got all the water in the humidifier in my face! I have been on CPAP for 3 years and I have never gotten rainout, let alone being water boarded!!!
Up until 2 nights ago, it seemed like I wasn't getting moist air at all with the air coming through to my mask.
