6 Important Considerations When Buying RV Dehumidifiers
I have told you about the best RV dehumidifiers. Now, let’s also get to know about the factors you should consider when buying a unit. Read below.
1. Size of Your RV
Factors such as the dimensions of your RV and the space you need to cover play a vital role in selecting the most suitable dehumidifier. Consider the following aspects to guide your decision:
Compact Solutions: For smaller RVs and campers, non-electric dehumidifiers can often work well. Look for options suitable for spaces around 200 square feet.
Normal Dehumidifiers For RV: As your space increases, consider dehumidifiers designed to remove moisture from the air for areas ranging from up to 300 square feet.
2. Think of the Weight and Portability
Portability is an important aspect when choosing a dehumidifier, particularly for RVs. Think about how often you’ll need to move these dehumidifiers because they can be carried around. The lighter ones like Eva-Dry or Pro Breeze dehumidifier should be a good pick.
The heavier ones might be harder to keep in place while traveling. If you choose a heavier option, make sure it consists of one of the following things for portability:
Handle;
Wheels;
Cord grooves.
3. Sound Levels of RV dehumidifier
Using a quiet dehumidifier is beneficial. It ensures a peaceful and undisturbed environment, allowing for a good night’s sleep and minimal disruption during daily activities. I would recommend you pick a unit that operates at around 50 dB or less.
4. Drainage and Emptying Tank
The best RV dehumidifiers have two options for drainage:
Water Tanks: Dehumidifiers collect moisture in removable water tanks. The size of the tank determines how often you need to empty it.
Drainage Pipes: Some models come with drainage pipes for continuous use when placed near a sink. This feature is typically not available in most dehumidifiers suitable for an RV.
5. Power Consumption
Considering the power consumption of a dehumidifier is crucial. This is because RVs have a limited power supply. Let’s shed light on a couple of important considerations:
During the journey, if you rely on generators to power your appliances, using a dehumidifier that is energy efficient can help to save fuel.
RVers often spend time in remote areas where electricity is not readily available. If you are also planning to visit a remote area, I would recommend you use a unit that is energy efficient like my favorite HomeLabs dehumidifier. It will help to extend the battery life of the RV.
6. Humidistat & Timer
While it’s not hard to monitor the dehumidifier’s progress, it’s probably not something you want to be worried about. So I would recommend you go for a unit like Eva-Dry EDV-1100 that features automatic settings to save yourself time and effort.
The humidistat measures the humidity level in the RV. It turns off the dehumidifier automatically when the air reaches the desired moisture level. This reduces energy usage while maintaining an optimal humidity level.
