What are common sources of air moisture in an RV?
The following are the most common sources of air moisture:
- Humidity outside the RV
- Showering and bathing
- Steam produced by cooking
- Water vapor as byproduct of burning propane
- Exhaled air by people and pets
Steps to reducing condensation
The precise conditions under which condensation will form varies due to numerous factors, such as: outside & inside temperature differential, size of recreational vehicle (air volume), ambient humidity, number of occupants and their living habits, etc.
To reduce condensation, take one or more of the following steps:
- Run a ceiling exhaust fan while showering
- Run the stove hood exhaust fan to expel moisture caused by cooking
- Run a dehumidifier
- Leave closet doors open to prevent condensation in corners
- Leave cabinets and drawers slightly open to prevent condensation on back walls
- Use a fan to circulate air in trouble spots
Under extreme conditions it may not be possible to completely eliminate condensation. In those cases make it a point to wipe down wet surfaces with a dry towel and consider adding insulation to the affected areas, if possible.
