I've mentioned this before... But got no ideas.
I posted about week or two ago about having a short term odor when starting when I go to bed. I've not been sure of the source of the smell, but now I am. When I last mentioned it, I had just washed out everything and cleaned everything. Today, when I was going to wash the mask, hose, and the rest, I sniffed every part, but found no smell... Not even the fan ( base or basic) unit. BUT, out of curiousity, I hit the start button and pointed the outlet at my face... YUP! It lasted about 20 seconds or so before it was faded to undetectable. Mind you, this base unit has been sitting since late morning, open all the way around to the air. (not even the lid to the water res was closed, and that's how I tend to leave it after dumping the water) I also noticed that the little air "filter" has had a small amount of dust leak past the edge and leave a trace into the intake. I have not noticed that before, but now it's more like summer, and lots of outside air is circulating in my house.
I've had a noticeable smell before, too, not always the same. The first one was about 3 weeks after starting to use it, I'd wake up during the night to an odor that reminded me of overheated wires - not that it smelled just like them. I assumed this was something about the heated hose "gassing" a little when warmed a lot (very cold in the house). But after a couple months I've never smelled it again.
About 3 months ago, I noticed the onset of a similar (to now) smell when starting, but it lasted about 2-3 days and vanished.
I find the smell very unpleasant (though not strong). Any suggestions?
