We are here to pick and choose the best dehumidifier for van life! Or if you should even use a dehumidifier in a van?
Let’s get straight into that question, a van is a small space so a dehumidifier wouldn’t be successful. But there are other alternatives on the list as well as ways you can prevent condensation below.
When it comes to camper vans, condensation is typically formed when you are heating the inside of the vehicle on a cold day.
Warm and moist air inside the van comes in contact with any cold surface, like a window, and it immediately forms into vapor or condensation.
Condensation will form in the coldest parts of your van:
- Windows
- Roofs
- Walls, if not properly insulated.

How Do You Dehumidify a Van?
A dehumidifier catches water vapor present in the air, turns it into liquid, and collects it into a container for easy disposal. In other words, it removes moisture from the air.

Best Dehumidifier For Van Life
A dehumidifier is nothing more than an air conditioning unit designed and optimized for collecting water: instead of focusing on blowing cold air into the room, it focuses on refrigerating the surfaces located within the unit, so water condenses on it.

Why Does My Van Have Condensation?
All air contains water molecules.
Even the heat from your body gives off moisture into the air. Running a heater, cooking, or moving around will give off gas and lots of vapor. In an enclosed space like a van, this builds up fast!
When there is a large temperature difference between the cold outdoors, and a warm humid van interior, condensation will form on the cold surfaces.
The most noticeable condensation will appear on your windows, it can also form on your roof or walls if not properly sealed. When lots of condensation occurs, droplets can stick together and create wet spots that quickly lead to mold or rust if not treated.
Wrapping Up
We hope you found the best dehumidifier for van life or but the absolute best thing is to prevent condensation in the first place. When you’re living in a small space, like a camper van, every bit of extra moisture can make things feel cramped and uncomfortable.
