Camco 44195 RV Mini De-Humidifier
This is, without a doubt, the most cost-effective dehumidifier on the market. It appeals to me because it requires little to no setup (other than removing the exterior packaging). You also won’t have to worry about plugging it in and draining your RV battery all day. Camco says that its dehumidifier can absorb up to three times its weight in water.
So, what exactly does that mean? Because the product weight is specified as little more than 6 ounces, I assume it can absorb approximately 18 ounces of water before being ineffective. You’ll have to replace it after that. That’s not a lot of absorption capacity for RVers who live in extremely humid climates.
As a result, this may be a preferable dehumidifying solution for part-time RVers or people who do not reside in areas with extremely high relative humidity. Consider placing many of these dehumidifiers around your RV’s space if you have a larger RV.

Despite its small size, it can remove up to 350 milliliters of water from the air per day and has a tank capacity of 650 milliliters. This means you’ll need to empty it every other day at most, but it includes an automated shut down feature that prevents it from overflowing until you realize it’s full.
With a power draw of only 25 watts, it won’t drain your RV’s onboard battery. It has a sleep mode that decreases the sound to less than 34 dB. This is an excellent feature if you’re a light sleeper who doesn’t want a lot of white noise while you’re attempting to sleep.
How to buy the Best RV Dehumidifier
Types of Dehumidifiers for RV
Dehumidifiers generally fall into two categories: desiccant (rechargeable) or refrigerant. Refrigerant models use a coil cool method to collect condensation in a bucket or reservoir. Desiccant dehumidifiers absorb moisture using water-soaking material, requiring no power supply or frequent emptying. Each type offers unique benefits and drawbacks for RV owners.
Rechargeable or Desiccant Dehumidifier
Desiccant models are ideal for small spaces like closets and tackling mold in specific RV areas. However, they may not handle excess moisture throughout the entire vehicle.
Refrigerant Dehumidifier
For comprehensive moisture control in your camper, refrigerant models are more effective, provided they have sufficient capacity. If high humidity is not a constant issue, a refrigerant unit might be unnecessary.
Key Considerations
Space Measurement
Accurately measure your van’s space in square feet or meters to select the right dehumidifier size. This ensures effective humidity control and prevents purchasing an ill-fitting unit.
Energy Efficient
Look for energy-efficient models to save power on the road. Some dehumidifiers operate without cords or batteries, using shore power to recharge for up to eight days.
Temperature and Humidity Levels Measurement
Determine your van’s temperature to choose the appropriate dehumidifier. Temperature impacts humidity levels, influencing your dehumidifier choice.
Easy to Transport
Opt for a compact, easy-to-store dehumidifier, ideal for van travelers. Portability enhances manageability and convenience.
Easy to Install
Choose a dehumidifier with simple installation, allowing easy setup and storage during travels.
Water Capacity to Remove Excess Moisture
Consider the dehumidifier’s water capacity. For extended trips, a larger capacity is beneficial, while short trips may require a smaller unit.
Noise
Prioritize quiet models using Peltier whisper technology to maintain a peaceful environment in your van.
Easy to Control
Select a user-friendly dehumidifier with digital controls, allowing you to set specific humidity levels for optimal comfort.
Frequently Asked Questions
What is an RV Dehumidifier?
Dehumidifiers excel at one primary task: removing moisture from the air. Regardless of price, all units serve this function. Air from your RV enters the dehumidifier’s vent and passes over cool coils. As warm air meets these cold coils, condensation forms and collects in a bucket or reservoir. The process varies by dehumidifier type. Basic models require manual emptying of the water bucket once full.
How to choose the right RV dehumidifier size?
To choose the right RV dehumidifier size, consider whether you need a unit with a drain hose or without. It’s crucial to match the dehumidifier’s capacity to your RV’s size. For smaller RVs, opt for compact units that efficiently remove moisture. Check both the unit’s dimensions and tank size. A 30-pint capacity is often ideal for RV use, reducing the need for frequent emptying.
