Ways to reduce humidity inside an RV



Your RV’s humidity level needs to be determined first.  A cheap hygrometer / thermometer is the best way to do this.  It is ideal to have a relative humidity of 30%-50% in your home. Following identification of the problem, you can try the following:

Cool the room.

Air Conditioner reduces your electric bill as well as removes moisture from the air in humid climates. Running the AC may help, depending on how hot it is.

Vents or windows

When indoor air is more humid than outdoor air, opening windows or ceiling vents can let some of that moisture escape.  Ceiling vents will work better than single windows since hot air rises.  When performing activities that generate a high level of water vapour, such as showering, cooking on the stove, or releasing pressure from an Instant Pot, this is especially important.

Improve airflow

Your RV’s air temperature can be evenly distributed by running a fan.  A fan will help humid air escape more quickly if a window or vent is open.

Dehumidify the room

Dehumidifiers can help remove moisture from the air without cooling it.  You can choose from a variety of dehumidifiers, just make sure the one you choose is appropriate for the space you intend to use it in.  Especially if you live in an area with higher humidity levels, pay attention to how many pints it can hold; the more it holds, the less often you’ll have to empty it.  You can use two small ones instead, or even start with a small one and then add a second if needed if you don’t have room for one the size you need.

Absorb moisture

Crystal moisture absorbers, such as Damp Rid, are great for boondocking and RV storage when running an electric dehumidifier isn’t possible.
