DreamWear nasal Cushion air vent makes a high pitch whistle noise

[watertrails]

I just got a Respironics DreamWear nasal Cushion . THe air vent on the mask sometimes makes a very high pitch whistle noise. I can cover the air slit with my finger and it stops. I pull out the 2 ends away from my face and invert it some and it stops it for a while. I love the mask if not for that. Has anyone else had this problem ?

It may be caused by water droplets near the vent holes. My solution is just flick it with your finger a few times to help displace the water drops and that usually takes care of it. I pull it out a bit while it’s still on my face and flick it.

What Nightynite said. I've had this happen from water building up. Do you have a heated hose? That can help.

Thanks , Ill try that. No, I dont have a heated hose. I suffered all winter in temps in my home down to 45 degrees. The DME only had luna 2s in that dont support a heated hose. I had never used cpap and didnt know how critical a heated hose was for me or i would have waited months for a nother maching. Medicare will only get  you a new maching every 5 years .The DME said they are going to try and get me a heated hose by next fall but i dont know if thats possible with the luna. Wonder if there just talking   AS my sleep doctor said they should get me a nother maching in 3 months from my start date which is may 1st. or medacare wont pay for it . They wouldnt do it. they said d there working on getting me a heated hose.

Watertrails- Go on Amazon and get a ( cpap hose cover) you can get one for $10.  It will insulate your hose and cut down on the inside moisture.  I use one and it works fine, I don’t have a heated hose either.

I super good insulated it ( thick rubber pipe insulation )  and most of it is was kept  under my bed covers also.. When its about 60 degrees in the house now ,  I am fine with no heated hose.. (unless  condensation is causing the air vents whisle noise ) But at 45 degrees inside, the cold air itself going into the maching and then blowing in my nose and throat was just misurable. I could just have the humidity on 1 or water would be dripping int the mask, So the air itself was still very cold. even before it went through the tubing.

[Nightynite]

Yep, the warm air from your lungs hitting the cold air from your home is causing the condensation in the hose.

Ah, ok. You can buy a hose cover that goes over any hose.

I meant nose cushion not hose.

Thanks all, I think it was from condensation. Its been warm the last few nights  and i had no whisles.
