For about a week, I've been experimenting with a method to reduce the rainout problem most of us experience with the Aura mask.
I've been using this mask for about a year......and I really love it......except for the nose full of condensation I sometimes get. Not fun!
I'm running my humidifier (M-Series Integrated) on a setting of (1), my overhead hose has a flannel cover (insulated), room temperature never drops below 70 degrees, and the relative humidity stays just under 50%.
The moisture that collects in my mask forms from my exhaled breath....and nearly all of the tiny droplets accumulate in my removable nose-piece.
Like a drop that gets bigger as it runs down a pane of glass, the big drops that enter my nose are formed from the much smaller droplets.
So.......here's the fix:
I inserted a couple of pieces of heavy cotton string in my removable nose-piece. When a drop finally grows big enough to roll into my nose, it touches the cotton string....and is instantly reduced in size by absorption.
So long as I can keep the condensation in tiny droplets, the moisture doesn't bother me. The cotton string does that job for me.
To insert the string, I pull a double length through the nose-piece with a stainless steel fishing "leader". It's about a foot long...with a little loop on each end.....and it does a great job of "fishing" the string pieces through the mask.
When the two pieces of string are in position, I clip the ends flush with the top of the nose-piece (each piece of string ends up being about 7" long).
Every morning, I disconnect my mask and hose from my CPAP machine....and re-connect it to a drier that blows a gentle breeze of filtered air through it....all day long. In this way, the string and the mask is completely dry as I get ready for bed.
If I didn't have a drier (not commercially available....I built it myself), I'd remove the damp string every morning....and replace it with dry string every night.
So far, I'm very pleased with the "string trick"....and I see no reason why it won't be a permanent part of my therapy.
