Hello, I have a ResMed S9 with H5i Humidifier and Climate Lined Tube and it use to work great. When I first started using this system 5 years ago, a single humidifier tub of distilled water would last 8+ hours at the lowest setting of 60. Over the past few months, the tub runs out of water within 4-5 hours and it seems the humidifier is running at a much higher level blowing hot air causing me to wake with a dry mouth. I replaced the climate lined tube thinking the sensor was not working but it didn't help.
Is there anything else I can do? Does the system need to be tested/calibrated/fixed by the manufacturer or by the CPAP supply company I purchased it from? Has anyone else had this problem?
Thank you community!
