RV Dehumidifiers – What Should You Know?
Condensation In Your RV
Have you noticed the formation of condensation on walls and windows of your camper, especially in colder and damper weather? Condensation happens when water vapor from the warmer humid air inside your camper comes in contact with the colder window surface. The condensation can seep into crevices of your RV and cause structural damage or formation of mold.
Causes Of High Humidity In Your Camper
RVs and campers are peculiar living spaces. There are usually a couple of people living in a little space. The daily activities such as cooking and showering add to the moisture content of the RV. In warmer weather, airing out your RV can help a lot, but in the winter it is not an appealing option. That’s when a dehumidifier comes in handy.
Types Of Dehumidifiers For Campers
The type of dehumidifier you need in your RV depends on the effect you are aiming for and the conditions around your motorhome. If you need to keep the moisture away from just some areas of your RV, a small desiccant or thermoelectric unit will be enough. To dehumidify the entire RV, you should get a nice refrigerant dehumidifier.
Sizing Your Motorhome Dehumidifier Right
When it comes to dehumidifying your travel trailer, sizing is everything. You should get a unit that is just right for the square footage of your camper. A unit that is too small will not show much effect, while a too-large one will cost more to buy and spend too much energy.
