Maintaining a comfortable and healthy living environment in your RV is essential, especially when you’re on the road for extended periods. One challenge many RVers face is excess humidity.
Whether it’s due to cooking, showering, or simply breathing, moisture buildup can lead to condensation, mold growth, and a stuffy atmosphere.
This guide explores the best dehumidifiers for RVs, helping you understand the different types, key features to consider, and our top recommendations for keeping your space dry and comfortable.
Why You Need a Dehumidifier
Humidity is a common problem in RVs, especially in humid climates or during rainy seasons. Everyday activities like cooking, showering, and even breathing contribute to moisture in the air.
This moisture can condense on windows, walls, and other surfaces, creating a damp environment that can lead to a variety of issues.
Humidity and Condensation
Condensation occurs when warm, moist air comes into contact with cooler surfaces. This can happen when you cook, shower, or even breathe, especially when the outside temperature is lower than the inside.
Condensation can lead to water damage, mold growth, and a musty odor.
Preventing Mold and Mildew
High humidity levels create an ideal environment for mold and mildew to thrive. These fungi can damage your interior, including fabrics, upholstery, and even the structure itself.
Mold and mildew can also trigger allergies and respiratory problems, making it essential to control humidity and prevent their growth.
Comfort and Air Quality
Excessive humidity can make your living space feel stuffy and uncomfortable. It can affect your sleep quality and overall well-being.
A dehumidifier helps to remove excess moisture from the air, creating a more comfortable and breathable environment.
Types of Dehumidifiers
There are two main types of dehumidifiers commonly used in recreational vehicles:
Compressor dehumidifiers and Desiccant dehumidifiers.
How Compressor Dehumidifiers Work
Compressor dehumidifiers use a refrigerant to cool the air, causing moisture to condense on cooling coils. The condensed water is then collected in a tank or drained through a hose.
These are generally more effective in warmer temperatures and are a suitable choice for larger RVs or those with significant moisture issues.
Desiccant Dehumidifiers: A Different Approach
These devices use a desiccant material, such as silica gel, to absorb moisture from the air. They then heat the desiccant material to release the moisture, collecting it in a tank or draining it.
They are more effective in colder temperatures and tend to be quieter and more energy-efficient than compressor models.
Choosing the Right Type
The best type of dehumidifier for your needs depends on several factors, including your climate, the size of your RV, and your personal preferences. Consider the pros and cons of each type to determine which is best suited to your needs.

Choosing the Right Dehumidifier: Factors to Consider
Capacity: Understanding Dehumidifier Capacity
Dehumidifier capacity is measured in pints, which refers to the amount of water the unit can remove from the air in 24 hours. Choose the right pint dehumidifier based on the size of your RV, the level of humidity you experience, and the number of occupants.
A 30-pint dehumidifier is generally sufficient for a medium-sized RV, while a larger RV or one with high humidity levels may require a 70-pint or larger unit.
Size Matters
Consider the physical size of the dehumidifier as well. Choose a compact unit that fits comfortably in your RV without taking up too much space.
Some dehumidifiers are designed specifically for small spaces, such as the oz small dehumidifier for bedrooms, bathrooms, and RV closets.
Features: What to Look For
Look for dehumidifiers with features that make them simple to use and maintain. Auto-shutoff features prevent the unit from overflowing when the water tank is full.
A continuous drain option allows you to connect a hose for continuous water removal, eliminating the need to empty the tank manually. Adjustable humidity settings allow you to customize the humidity level to your preference.
Hose: Continuous Drainage
A continuous drain hose can be a convenient feature, especially if you plan to use the dehumidifier for extended periods. It allows you to connect the dehumidifier to a drain, such as a shower drain or even your RV’s gray tank, for automatic water removal.
You could even use a garden hose for draining outdoors.
Quiet Operation
Choose a quiet dehumidifier to maintain a peaceful environment. Look for units with low decibel ratings or those specifically designed for quiet operation.
Energy Efficiency
Energy efficiency is an important consideration for RVers, especially those who rely on shore power or limited battery capacity. Look for dehumidifiers with high energy efficiency ratings to minimize power consumption.
RV Dehumidifier FAQs
Placement and Maintenance
Place your dehumidifier in a central location in your RV for optimal performance. Avoid placing it near vents or heat sources, as this can affect its efficiency.
Regularly empty the water tank and clean the filter to ensure proper operation.
Troubleshooting Common Issues
If your dehumidifier is not collecting water, check that the unit is turned on, the humidity setting is correct, and the air filter is clean. If the unit is making unusual noises, check for any obstructions or loose parts.
Beyond the Dehumidifier: Controlling Humidity
Ventilation and Air Circulation
Proper ventilation and air circulation are essential for controlling humidity. Open windows and vents when possible to allow fresh air to circulate.
Use exhaust fans in the kitchen and bathroom to remove excess moisture.
Moisture Absorber: Alternative Solutions
Moisture absorbers, such as DampRid, can be a helpful addition. They are particularly useful for small spaces or areas prone to moisture, such as closets, storage areas, and under sinks.
