humidity in bedroom

Hi. I am new to this group but have been using a clap for just over a year now. I have a question regarding humidity in bedrooms. If I don't have the heat on at all in my bedroom, everything feels damp and if I do put the heat on, it feels very humid in there. Hubby thinks it may be due to my clap machine. Has anyone else experienced this?

There is about one cup of water in a cpap humidifier. Adding one cup of water (assuming you use it all) over the period of 8 hours will not make an appreciable difference to a whole room.

You must live in a humid location (relatively near water).

My whole house seems to be humid this year. All my windows are getting condensation on them, even the double pane ones. The only change I have made is a new CPAP machine. I agree with the above poster who says there is not enough water in the machine to make a difference though. Maybe it is body water from breath and perspiration.

Did you seal up any new windows or change the room temperature? Condensation forms where warm humid air meets cold air. Changing the temperature a few degrees can change the dew point and cause that to happen.

There are some cheap digital thermometers that show humidity while recording high an low. You might want to look into one of those.

If you have a real humidity problem, you need to get it fixed soon as it will result in black mold and that is toxic. Make sure you gutters are clean and that your water bill is like what it was last year. Any flat roof spaces should be checked for holding water. Is your clothes dryer vented out side and is that clogged? Have you noticed a musty smell anywhere in the house? Is anyone taking longer showers? Is the vent fan in the bathroom no longer working or no longer used?

The cup of water will increase the humidity but only very slightly. A typical ROOM humidifier will hold a gallon or two and go through that in a night. My S9 might use two ounces at most and many people breath out about 16 oz of water a day.
