evil mask noise
Here's the noise my mask makes, right in my face and loud, when condensation forms on the vent holes.
What I'm thinking of doing is covering most of the vent holes and drilling one wider to get the same air flow but wide enough not to become a water whistle.
Wonder if anyone has tried that?

Hi
My first question is why is condensation forming? I very occasionally get some condensation, may be once a month, but I can quickly run a finger around the inside of the mask, and wipe it away. I use a nasal mask, with the humidifier on my machine. I like the bedroom no warmer than 18C and have a fleecy cover for my hose.
I'd be nervous about replacing a load of pepper-pot holes with a larger hole. I would worry about the air finding its way out through the hole, rather than up your nose.
May be a different model of mask would do the trick.
[I am also plagued by noise, but it seems to be a fault with the machine]
Jonathan.

Hi Jonathan, well see my nose is blocked a lot, so I mouth breath which really sucks a lot more moisture and makes my mouth dry. So I put humidity on maximum, which makes for condensation at the mask end, which becomes a demonic reed instrument.
Now it's colder it's a lot noisier. During summer it wasn't much of a problem.
The mask is one that has grid of small holes. It takes ten minutes to start whistling on a bad night. A wipe with a finger shuts it up for a minute but it starts again.
So I tried putting oil inside on the holes - because it's water repellent - and this did seem to cut it down a notch but still a problem.
I assume that the moisture on the edge of the holes can only make a noise because they a small, so the solution is to make a large hole.
But that could screw with the flow rate so it would mean covering the rest. I don't know why they aren't manufactured with just one big hole - something I will ask about.
Actually, as I write, it occurs that some sort of gauze over it might fix it - something very loose weave.

So I tore some fabric from one of the filters and glued it over the holes - and it worked!
It was dead quiet, and the air was still flowing freely.
It was quiet all night then after a few hours a bit of whistling until I gave it a wipe.
Vast improvement.
