Air Fit F20 Face Mask - Condensation Issue from Breath - xirokx - 08-24-2024
Hi there,
I have a F20 Air Fit mask that has condensation issues from when I exhale because I have a naturally cool room. I do not use fans or AC etc, its just a cool room all year round, temperatures are 20-21c in the Summer and lower in the winter.
The trouble I am experiencing is due to the ambient temperature of the room, its causing condensation in the full face mask that is turning into water droplets within 2-3hours causing the mask seal to loosen and drops of water (ALOT) waking me up, wet and frustrated.
Last night I lined the inside of the mask with paper but am looking for a more robust solution. I cannot use mask liners around the perimeter of the mask I need something that is quick and easy to put on the inside, remove in the morning and setup in the evening again. I was thinking to make some kind of mask cover for the outside but also need to put something on the inside. I dont know how to line the inside of the mask to mop up the water vapour from the con
I now firmly believe this is a design issue affecting a large number of people so cannot be the only person suffering. So am desperately seeking ideas.
What do you put on the inside of the mask to mop up the moisture inside the mask?
Thanks so much
P.S. if you have a solution, please can you post pictures as I am a visual person .

Have you tried a heated hose with an elevated temperature?
RE: Air Fit F20 Face Mask - Condensation Issue from Breath - xirokx - 08-24-2024
Yes I have both it's nothing to do with condensation in the mask due to exhaled air...thanks anyway

We see this a lot. It is condensation that can be avoided by using your heated hose set at a temperature somewhere in the 80s F. Another way to avoid condensation is to use a hose hanger that routes your hose up above your head so the water cannot travel uphill. My hose is set to 84 degrees and is held up by a hose holder and I have never had condensation. Hope this helps.

Thanks for your reply but sadly it's not the answer. Your response is the answer for rainout in the tube or in the mask that has run down from the tube. This is different.
Read here you'll see
The air we breathe out is warm and moist, as it contains water vapor from the lungs and respiratory system. When this warm, moist air comes into contact with the cold outside air, the water vapor quickly condenses into tiny liquid water droplets. This condensation occurs because the cold outside air cannot hold as much moisture as the warm exhaled air.
The temperature difference between the warm, moist air you exhale and the cold outside air causes the water vapor to condense. This is similar to how water vapor in the atmosphere condenses into clouds or fog when warm, humid air encounters cooler temperatures.

Check out Loq response you'll see what I mean
So now I need to find a solution to line the inside of my mask to mop up the water vapour that is made from my exhaled breathe. Not excess water from my heated tube that is already at 84f and is hanging from a hose
Thanks

Remember, air is still injected into the mask during the exhalation period.
I set the hose temperature to maximum and used a hose cover (a thermal insulator you can buy on Amazon) to ensure that the hot air reached the mask.
I have no problem whatsoever with condensation.

The other thread has several pages of attempts to help get this resolved. This probably should be merged to keep continuity of the discussion.

You might need to insulate your mask or heat it. If your heated hose is at Max temperature as I suggested over there, and turning off humidity with no added water, this is about all there is left to address. Insulate the mask itself.
RE: Air Fit F20 Face Mask - Condensation Issue from Breath - Deborah K. - 08-24-2024
Yep. Turn the hose heat up as high as it will go, and continue to use your hose holder and hose cozy.

My hose was set to maximum but the problem continues because it's precisely as Sarcastic Dave says "I need to insulate my mask" but don't know how
@SarcasticDave94 I don't understand how they're insulating the mask? Do you ? Can you explain pls?
@Deborah I have done that and it still an issue, I need to do what SarcasticDave says.

Instead of using paper to insulate your mask, you might try some flat, square cotton pads, the kind designed to be used as bandages.
They are available in various sizes and thickness. I would think that they would be easy to use. Just use some scotch tape that is sticky on both sides to adhere them to your mask.
I'm just thinking outloud.............
