Air Fit F20 Face Mask Condensation Issue from My Breath

[xirokx]

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 .

Last night I lined the inside of the mask with paper

Not recommended! The paper might slip and block the vent ports! Dangerous!

Some things to try:

- Use a heated hose.

- Turn the humidifier setting down. (A common newbie mistake is making the humidifier setting too high.)

- Make sure the hose runs down toward the machine. This will allow the rainout (condensation) to run back into the humidifier.

- Use an insulating hose cover. Example: https://www.cpap.com/productpage/snugel ... hose-cover

Given how much water is in your mask, the rainout is probably happening inside the hose from the machine to the mask. In any case, the above tips should help.

Thanks for your suggestions

They would help if it the condensation in my mask was due to rainout issue from the hose but its not as stated. Unfortunately, many "so called" experts fail to understand this.

Here's a good learning opportunity:

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.

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.

Btw I do use a heated hose with cover and hose hanger too. Also my humidity is off, there is no water in the chamber and the tube temp is 81f.

Thanks anyway

try putting the hose and mask under the covers and sleep with the blankets over your head. sounds ridiculous but since I started doing this, no rain out or condensation.

If you are able to exhale through your nose I think that could help with your issue.

Maybe you failed to say what your humidifier settings are, whether you are using a heated hose, and how your hose is positioned. You should have expected the answers you got.

You don't have to mansplain' basic fluid physics. I understand you are frustrated. But, you know so damn much, why haven't you solved the problem on your own?
