The Best Dehumidifier for RV

Based on the criteria above, choosing the best RV dehumidifiers can seem daunting. But we have listed the top options for you based on what we think you’ll appreciate most in an RV dehumidifier.

And it only uses 23W per hour of energy so you can run it off your inverter or shore power if you have it. This is great for a small RV, but can also be useful if you have multiple rooms and want to dry out the kitchen, bedroom or bathroom separately.

RV Dehumidifier Buying Guide

RV dehumidifiers come in a variety of shapes and forms and have numerous bells and whistles. But their purpose is always the same – to keep humidity levels low to protect against mold and mildew.

Here are a few things to consider when deciding which is the best RV dehumidifier for you.

  • Type of RV dehumidifiers. There are two major types of RV dehumidifiers: desiccant and refrigerant.
    • A desiccant dehumidifier uses a silica gel to draw moisture out of the air. They are as simple as the disposable moisture absorbers and can get more complex and mechanical.
    • A refrigerant dehumidifier pulls air past cool coils where water from the air condenses and is collected to be removed.
    • You’ll also come across Peltier dehumidifiers, which use thermoelectric principles to grab moisture from the air. Our favorite – the Pro Breeze Electric Mini dehumidifier- is a Peltier.
  • Power Consumption/Energy Efficient. Since power consumption for any appliance in an RV is important, you are going to want to have an RV dehumidifier that removes the most moisture from the air with the least amount of energy. All of our recommendations below have relatively low energy consumption.
  • Extraction Rate. You want a dehumidifier that will remove excess moisture in the air without taking it all day. Some RV dehumidifiers have higher extraction rates than others.
  • Quiet Operation. Choosing an RV dehumidifier with quiet operation is essential for enjoying life on the road. Most options range from a light hum to having a noise level of virtually nothing at all.
  • Portability/Size. A portable dehumidifier, like those recommended for RVs, tends to be quite small. And since space is always an issue, having a small dehumidifier for RV living is essential.
  • Tank Capacity. Because most RV dehumidifiers are small they typically cannot remove very much moisture in the air per day without being emptied. There are continuous drainage options so you won’t have to empty the tank very often. But most portable dehumidifier options will require that you monitor when the tank is full to empty it.
  • Additional Features (automatic shut off feature, water tank indicator light, timer). There are always bells and whistles you can find when shopping for the best RV dehumidifiers.
    • An automatic shut off feature will allow the dehumidifier to shut down once the desired humidity level is reached. While not necessary, this can be nice.
    • Likewise, a water tank indicator light that tells you when the water tank capacity is full is helpful to manually maintain the humidity level inside your RV.
    • And a timer can be useful if you’d like to set specific times when you want the dehumidifier to run or not run.
