I have been on CPAP therapy for almost a year. Until this month my machine has been working fine. However, my humidifier doesn't seem to working right anymore. The hot plate used to be too hot to touch in the morning. Now it's warm but not hot. Before when I set it to 4, my face was pleasantly damp in the morning. Now my sinus are dry and even at a setting of 5 I don't feel the humidity. The water tank is about half empty in the morning but it used to be almost completely empty.
I have taken it apart and snapped it back together. I didn't feel any obstruction in the air outlet ports. I checked the settings and the humidifier is set to on and the light that states it's function is also on during the night.
The troubleshooting guide in the manual states that if the device is operating normally but the humidifier's airflow is low, there is probably an airflow obstruction and I need to take it to my home care provider. Before I do that, do you have any suggestions on what I can try. I won't be able to get to my home care provider for at least a week and probably longer. This dry nose is affecting my sleep.
Thanks for any advice you have.
Do you have the older model 450P or the newer 460P?
I would suggest you contact your DME and tell them. Perhaps it can be replaced under warranty.

You might get more humidity if system one humidification is turned off in the clinician's mode. That way, it doesn't try to sense the humidity of the air coming into the machine, and it simply heats the water a certain amount.
