Welcome!

It should be nearly silent. You might have too much water in the humidifier. Try with less water. Or one of the silicone seals might not be in exactly the correct position. They are meant to be removed and re-attached, so check them.

Hi stanzani,
WELCOME! to the forum.!
It sounds like you might have filled your humidifier tank too full.
You will get a gurgling sound if you overfill it. I know there is a line, but I'm not sure where it is because it isn't embossed where I can actually feel it, I think it is a mark and you should be able to see it.
Hang in there for more suggestions, good luck to you with your CPAP therapy.

You might try operating the blower with the hose attached directly, without the humidifier. That will narrow down the source of the noise. Your description sounds like there may be water in the hose.
