Condensation in mask only

I've been on the hose for 9 months now. And for maybe the last 5 days I've been getting condensation in my mask only. There is no moisture in the hose at all...just the mask and the tube connecting to the hose. Any idea what is going on? Its quite annoying to wake up and have water dripping down your nose in the middle of the night. I have not changed anything in my routine or use, also it happens with or without water in the humidifier tank but mind you, even when its filled I don't turn it on. Any advice you might have would be appreciated it.

Thank you!

I have 2 thoughts,
1) It's getting colder so condensation will form easier.
or
2) Your mask vent is blocked or you are blocking it (with your pillow or blanket etc) which will definitely form condensation in your mask, from the moisture in your breath.

Any other thoughts?

Pure speculation, the seasonal drop in temperature is probably the culprit. The potential solution would be any of the following: insulating the hose, a warmer room air temperature, going without the humidifier. The condensation occurs when the saturated air cools down. The solution is to reduce the moisture or humidity in the hose or to keep the airflow at a temperature above saturation. I am sure others will give you additional excellent advice and tips.

I had that problem with my S8 and Activa. The room temp is at 21C, which is low.

The solution was to insulate the small hose from the mask to the long hose. The 6 feet hose was already insulated.

In the past I used S8 an Activa with small tube insulated, no heating at all but long hose very well insulated, the humidifier was not more than 2.5 and I had no problems at all.

The other day I was using the S8 again with the heated hose (Aussie) and I noticed water forming inside the mask (Aeiomed Headrest without small hose insulation) not in the hose. Technically this should'n be happening because I'm heating up the hair and the humidifier is set at only 2. But I think the mask hose need to be insulated too.

Yesterday I installed back again the PR System One and added insulation to the mask's hose. This morning I didn't noticed any condensation. The humidifier is set at 3. I need to say that in summer time the house was at 23C and I had no problem using the PR System One with the Headrest not insulated.

so I suggest you to insulate the mask hose.

Hey Ppharman, instead of working on a heated hose, take a popular mask and re-design it with a heating element in the short hose and cavity over face. john

Living in Australia, we have just come out of winter and its colder nights.
I know of a few people that have had problems of condensation of the out breath in the mask and its corresponding discomfort, but I don't know of any easy solutions.
The easiest solution is to turn the room temperature up, but that's not always feasible.
Turning the humidifier off may help, but that's not very comfortable.
Personally I pull the blankets over my head, something only a hose head can do.

Thank you!

greg-g is on the right track. The physics here is that your exhaled breath is warm and humid. Probably the room temperature has gone down in the last few days, and when your warm humid breath hits the now-cooler-than-before mask, you are getting condensation inside the mask.

The easy solution really is to pull the covers over your head and make a small little tent from them around your head and mask. I like to tuck the sheet under the pillow ABOVE my head. Your head will put off enough heat to warm up your little tent and keep your mask warm. No amount of insulating or heating the hose will fix this problem.

The less easy, but still not difficult, solution is to put some sort of wick inside the mask to absorb the liquid. I suspect if you search on "wick" you can find how people have done it. My favorite wick choice is to fold Kleenex tissue in a tight fold, then cut the Kleenex "rope" to the right length to fit inside the mask around the rim, then secure it with little dots of silicone earplug stuff at the ends and at each point where you need to bend the rope. You may prefer one of the more complicated solutions described by others, but it's really not necessary to make a big production out of this. Take the Kleenex out each day and discard (you can leave the silicone in). Create a new Kleenex fold and put in a fresh one each night.

LoQ is correct....your moisture is forming from exhaled breath.

I've been using a "wick" for two or three years......and it's stopped the problem.

I use a double-strand of cotton "butchers twine"......the string they use to tie up beef roasts with.

I use a different mask than you do....but, the principles are the same. PM me and I'll send pictures of how my system works.
