Best RV dehumidifier – What To Look For

If you’re looking to purchase an RV dehumidifier but aren’t sure which one to choose, here are some key factors to consider:

Size and Capacity

Choose a dehumidifier with the appropriate capacity for your RV or camper size. You don’t want to select a unit that’s too small and underpowered or too large and bulky.

Type of Dehumidifier

There are two main types of RV dehumidifiers: compressor and desiccant. Compressor dehumidifiers are more powerful and better suited for larger RVs, while desiccant dehumidifiers are quieter and more energy-efficient.

Power Source

Consider the power source required for the dehumidifier you’re interested in. Some run on AC power, while others require a DC power source, such as a battery or solar panel.

Noise Level

Remember the noise level of the dehumidifier, especially if you plan on using it while sleeping or relaxing in the RV. Look for models with noise-reducing features or that operate quietly.

Energy Efficiency

Choose an energy-efficient dehumidifier to save on power usage and costs. Look for models with an Energy Star rating or those that use a minimal amount of power.


If you plan on traveling frequently in your RV, choose a dehumidifier that’s portable and easy to move around. Look for lightweight models that are easy to pack and store.


Consider the quality and durability of the dehumidifier. Choose models with sturdy construction and good customer reviews to ensure the product lasts for years.


Finally, consider your budget when choosing an RV dehumidifier. Look for models that offer good value for money, balancing quality and affordability.
