How to Choose the Best Dehumidifier for RV?

Here’s your step-by-step guide to choosing the perfect dehumidifier that fits your RV lifestyle, your budget, and your square footage.

Understand Why You Need a Dehumidifier in Your RV

RV interiors are compact, often poorly ventilated, and exposed to changing weather. Cooking, showering, and even just breathing all add moisture to the air. Without proper humidity control:

• Condensation builds up, damaging windows and walls
• Mold and mildew can take hold in fabrics and corners
• Allergens increase, making it harder to breathe
• Your RV’s structure and resale value can suffer

So, whether you’re parked in the humid South or braving chilly Northern mornings, a dehumidifier can be your quiet protector.

Start with Your RV Size and Layout

Not all RVs are created equal. A Class A motorhome will have drastically different needs than a teardrop trailer.

Tips:

• For small campers or vans, go for a compact or mini dehumidifier (typically for spaces under 250 sq. ft.).
• For mid-size travel trailers and fifth wheels, choose a medium-capacity unit that covers up to 500 sq. ft.
• For large Class A RVs or full-time RVers, you may need a high-capacity unit or even two smaller units placed strategically.

Consider Moisture Removal Capacity

Dehumidifiers are rated by the pints of moisture they can remove in 24 hours. Here’s a rough breakdown:

• 20–30 pints/day: Small to mid-size RVs, light humidity
• 30–50 pints/day: Full-time RVers or high-humidity regions
• 70+ pints/day: Overkill for RVs, unless your unit is unusually large or extra wet

💡 Pro Tip: More capacity means less runtime and fewer tank emptyings.

Choose Between Desiccant vs. Compressor Models

Both have their place, but here’s how to decide:

• Compressor Dehumidifiers (like Frigidaire, hOmeLabs):
  • Best for warm, humid climates
  • Efficient for larger RVs
  • Noisy and heavier, but powerful
• Desiccant Dehumidifiers (like Ivation or EcoSeb):
  • Excellent in cooler environments
  • Quieter and more energy-efficient
  • Great for off-grid or solar setups

Don’t Forget Drainage Options

Do you want to babysit your dehumidifier every day? Probably not. Look for these features:

• Removable Water Tank: Easy but needs regular emptying
• Gravity Drain Hose: Great for continuous draining if your RV is parked level
• Built-in Pump: A must-have for permanent setups or if drainage is above the tank level

Portability and Storage Matter

Space is premium in an RV. Before you buy:

• Check dimensions—Will it fit near your outlet or under a table?
• Check weight—Can you lift it into storage when not in use?
• Wheels or handles—These are small wins that make a big difference on moving day.

Look for Smart Features That Make Life Easier

Modern dehumidifiers come with features that are surprisingly handy:

• Auto-restart after power outages
• Auto shut-off when the tank is full
• Built-in humidistat for set-it-and-forget-it use
• Digital displays to monitor exact humidity levels
• Timer functions for better energy use

Frequently Asked Questions When Selecting the Best Dehumidifier for RV

1. What size dehumidifier do I need for my RV?

The size of the dehumidifier you need depends on the square footage and layout of your RV. For small RVs or camper vans (under 250 sq. ft.), a compact unit or mini dehumidifier is usually sufficient. For medium-sized RVs or fifth wheels, a 30–35 pint model works well. If you live full-time in a large Class A motorhome or travel to high-humidity regions, consider a 50-pint dehumidifier for optimal performance. Always choose slightly above your size requirements if you want faster moisture removal and less frequent maintenance.

2. Is a desiccant or compressor dehumidifier better for RV use?

Desiccant dehumidifiers are better suited for cooler climates or low-power situations, such as off-grid or solar RV setups. They’re typically quieter and more energy-efficient. Compressor dehumidifiers are ideal for warmer, humid environments and can remove more moisture quickly, making them perfect for large RVs or long-term stays. Your choice depends on your travel region, climate, and power availability.

3. Can I use a home dehumidifier in my RV?

Yes, but with caution. While home dehumidifiers offer high performance, they’re often bulkier, noisier, and less power-efficient—factors that matter in an RV. If you choose a home unit, ensure it fits your space, has energy-efficient features, and includes a drainage option. Ideally, look for units marketed as portable or small-space models.

4. How do I drain a dehumidifier in an RV?

There are three main drainage methods:

• Manual tank: You empty the reservoir when full.
• Gravity drain hose: Connect a hose to allow continuous draining into a sink, shower, or floor drain.
• Built-in pump: These models can push water vertically into sinks or drains, ideal for permanent setups. If your RV is stationary or level, a hose drain is simple and low-maintenance. For on-the-go use, a unit with a large tank or pump is more flexible.

5. Where should I place the dehumidifier in my RV?

Place the dehumidifier in the area most prone to moisture—usually the living area, kitchen, or bathroom. Ensure the intake and exhaust vents have space to circulate air freely. Avoid cramming the unit into tight cabinets or corners unless it’s designed for enclosed spaces. For larger RVs, you might need to move the unit between rooms or use two smaller ones for balanced coverage.

6. How often should I run the dehumidifier?

It depends on your climate and how often you use your RV. In humid regions or during rainy seasons, you may need to run it daily. Modern units with built-in humidistats can automatically maintain your desired humidity level (ideally 40–50%). If you’re storing your RV, consider leaving the dehumidifier on with a drain line to prevent mold buildup.

7. Do RV dehumidifiers use a lot of electricity?

Most portable RV-friendly dehumidifiers are energy-efficient, especially those under 35 pints. Desiccant units tend to use less power than compressor models. Look for Energy Star certified products to reduce electricity use. If you’re boondocking or using solar, prioritize low-wattage models and consider using them only when necessary.

8. Are there quiet dehumidifiers for RVs?

Yes, some models operate at noise levels as low as 30–40 decibels, which is comparable to a quiet library. Desiccant dehumidifiers are generally quieter than compressor types. If noise is a concern (e.g., while sleeping), look for a unit with a “quiet” or “night” mode, and check user reviews for real-world sound feedback.

9. Can I use moisture absorbers instead of a dehumidifier in my RV?

Moisture absorbers like DampRid or silica gel work well in small, enclosed areas like closets, cabinets, or during RV storage. However, they can’t match the performance of an electric dehumidifier for full-time RV living or in larger open areas. Use them as supplemental tools, not as your primary solution.

10. What’s the best dehumidifier for full-time RV living?

For full-time RV living, the best dehumidifier is one that offers:

• High moisture capacity (35–50 pints)
• Continuous drainage or a built-in pump
• Auto-restart and humidistat control
• Portability with wheels or handles Top choices include the hOmeLabs 35 Pint, TOSOT 50 Pint with Pump, and the Frigidaire 22 Pint model for mid-size setups. Choose based on your RV size, climate, and how much automation you want.

11. Do I need a dehumidifier during winter RV camping?

Absolutely. Cold air holds less moisture, so condensation builds up quickly inside the RV, especially from cooking and showering. A desiccant dehumidifier works best in colder temperatures and helps prevent foggy windows, damp bedding, and mold during winter camping. Pair it with good insulation and ventilation for best results.

12. How can I maintain my RV dehumidifier?

Basic maintenance includes:

• Emptying and cleaning the water tank regularly
• Cleaning or replacing the air filter monthly
• Checking the drainage hose for clogs or kinks
• Inspecting coils for dust or ice buildup A well-maintained unit lasts longer and performs more efficiently, saving you time, energy, and repairs down the line.

Conclusion

After hands-on testing and careful review, it’s clear: the best RV dehumidifier is the one that fits your space, lifestyle, and climate needs. Some excel in small campers, while others dominate in high-humidity, full-time setups. Whether you’re looking for whisper-quiet operation, energy efficiency, or powerful moisture removal, there’s a top-rated option on this list just for you.
