Choosing the Right RV Dehumidifier: Your Essential Buying Guide
Keeping your RV dry is super important. Too much dampness can cause mold, mildew, and even damage to your RV’s insides. A good RV dehumidifier pulls that extra moisture out of the air. This guide helps you pick the best one for your adventures.
Key Features to Look For
When shopping, keep these main features in mind. They make a big difference in how well the machine works.
- Capacity (Pint Removal Rate): This tells you how much water the unit removes in 24 hours. Small campers need less power. Large fifth-wheel RVs need units that remove more pints daily. Match the size to your RV’s space.
- Portability and Size: RVs have limited space. Look for a compact unit that fits easily in a cabinet or corner. Wheels or handles help you move it between different rooms or storage areas.
- Water Tank Size and Auto Shut-Off: A bigger tank means you empty it less often. The best units have an automatic shut-off feature. This stops the machine when the tank is full, preventing messy spills.
- Noise Level (Decibels): You want to relax in your RV. Check the decibel (dB) rating. Lower numbers mean quieter operation. Some units are almost silent; others sound like a loud fan.
- Humidistat Control: This feature lets you set a target humidity level (like 50%). The dehumidifier runs until it hits that level, then turns off until the air gets damp again. This saves energy.
Important Materials and Build Quality
The materials used affect how long your dehumidifier lasts, especially when traveling.
Most good RV dehumidifiers use durable plastic casings. This keeps the weight down. Look for UV-resistant plastic so it does not get brittle in the sun if stored near a window. The internal components, especially the coils, should be made of corrosion-resistant metal. Moisture is the enemy, so metal parts must resist rust.
Factors That Improve or Reduce Quality
Quality often shows up in the details. A high-quality unit performs reliably for years. A low-quality one might break down quickly.
- Factors Improving Quality: Look for reliable brand names known for making appliances. Units with electronic controls (digital displays) usually offer more precise settings than simple dial controls. Energy Star ratings show the unit is efficient.
- Factors Reducing Quality: Cheap, thin plastic can crack easily when bumped during travel. Overly simple designs sometimes lack important safety features like the auto shut-off. If the reviews mention constant leaks or failing compressors, the quality is likely low.
User Experience and Use Cases
How you plan to use your RV affects your choice. Think about where you camp and how often you move.
Full-Time Living: If you live in your RV year-round, you need a powerful, continuous drainage option. Many units allow you to attach a hose directly to a drain or sink. This means you never have to empty a bucket.
Winter Storage: When the RV sits unused, moisture builds up slowly. A smaller, low-power unit might be enough just to prevent musty smells. You might even use passive desiccant bags in this case, though powered units work better.
Humid Climates (Coastal Areas): If you camp near the ocean or in the South during summer, you need maximum pint removal. Noise might be less of a concern than sheer drying power.
Good user experience means easy setup, simple emptying, and quiet operation when you are trying to sleep.
RV Dehumidifier Buying Guide: Top 10 FAQs
Q: What is the main job of an RV dehumidifier?
A: Its main job is to take extra water vapor (humidity) out of the air inside your camper. This keeps things dry and prevents mold growth.
Q: Do I need a special RV model, or can I use a home one?
A: You should use an RV-specific or portable model. Home units are often too big, heavy, and use too much power for an RV’s electrical system.
Q: How do I figure out the right size (pint capacity)?
A: Measure the square footage of the area you want to dry. Then, check the manufacturer’s recommendations based on how damp your climate is. Bigger RVs need bigger pint ratings.
Q: Is a compressor model better than a desiccant model for RVs?
A: Compressor models (refrigerant-based) are usually better for quickly removing large amounts of moisture in warm, humid weather. Desiccant models work better in cooler temperatures.
Q: What is “continuous drainage”?
A: Continuous drainage means you attach a small hose to the unit. The water drains out directly, so you do not have to manually empty the water bucket.
Q: Will a dehumidifier use too much electricity in my RV?
A: They use electricity, but modern units are more efficient. Check the wattage. If you are boondocking (not plugged in), you should run it only when your generator or batteries can handle the load.
Q: How loud is a typical RV dehumidifier?
A: Noise varies greatly. Aim for models under 50 decibels (dB) if quiet operation is important to you, especially for sleeping.
Q: Can I leave the dehumidifier running when I am not in the RV?
A: Yes, if it has a reliable auto shut-off feature and you are connected to shore power or have a reliable battery setup. This is great for winter storage.
Q: Where is the best place to put the unit inside the RV?
A: Place it centrally where air can flow easily around it. Make sure there is space behind it for air intake and that it sits on a level, stable surface.
Q: What happens if I forget to empty the water bucket?
A: If the unit has an auto shut-off, it simply stops working. If it lacks this feature, the water can overflow, causing damage to your RV floor.
