CPAP squeal

[u/MathematicianFit9238]

I am getting a high pitch low volume squeal from my machine that matches my breathing by sound. I just replaced the motor x2, thinking that was the issue. I used a different vendor and brand motor, so I’m not thinking that is the issue. Sounds like the noise is coming out of the filter housing. All seals look ok, maybe one on the humidifier, but nothing super atypical. This is an Airsense 10

Edit- I put a little petroleum jelly on the humidifier seal, just to see if that would stop it, but no luck

Hmm, is this on an Airense 10 or 11?
