I have just received my new Airsense 10 CPAP for a week.The tube is just the standard slim line. In the 1st and 2nd night, the water level was not changed. In the 3rd night, i tried to warm it and it seems working because the level was reduced 50% of the tub in the 3rd night. Then the 4th and 5th the water level was not changed again and the heated plate was a bit warm. Can you please advise me how to solve the problem.
P.S. I bought the CPAP from US, but now i am not in US. I would like to try as much as i can first.
Thank you very much,
