The Ultimate Buying Guide for Your RV Dehumidifier
Owning an RV is fun! But dampness can sneak in. High humidity inside your RV causes musty smells and even mold. A good dehumidifier keeps your space dry and fresh. This guide helps you pick the best one for your travels.
Key Features to Look For
When shopping, check these important features first. They make a big difference in how well the unit works.
Capacity and Coverage Area
Dehumidifiers remove water. You need a unit sized right for your RV. Small RVs need less power. Large fifth-wheel trailers need more. Look at the pint capacity (how much water it pulls out in 24 hours). Most RVs do well with a 30 to 50-pint unit. Check the manufacturer’s suggested square footage coverage too.
Water Collection Method
There are two main ways units collect water:
- Bucket Collection: The unit fills a tank. You must empty this tank often. This is simple but needs regular attention.
- Hose Drainage: Some models let you attach a garden hose. This lets the water drain directly outside. This is great for long-term parking or if you hate emptying buckets.
Portability and Size
RVs have limited space. Measure where you plan to put the dehumidifier. A compact, easy-to-carry unit is best. Wheels or sturdy handles help move it around.
Energy Efficiency
You run this unit using your RV’s power. Look for an Energy Star rating. This means it uses less electricity to do the same job. This saves battery life or shore power.
Important Materials and Build Quality
The materials used affect how long your dehumidifier lasts. RV environments can be rough.
Durable Outer Casing
The outside plastic should feel strong. Cheap plastic cracks easily. Look for thick, tough ABS plastic. This resists bumps while traveling.
Internal Components
High-quality internal coils and compressors last longer. While you cannot easily see these, reliable brands usually use better parts. Read reviews to see if users report early breakdowns.
Factors That Improve or Reduce Quality
Some features boost performance; others cause headaches.
Factors That Improve Quality:
- Built-in Humidistat: This lets you set a target humidity level (like 50%). The unit turns off when it hits that level. This saves energy and prevents over-drying.
- Automatic Defrost: If you use the unit in cooler weather, ice can build up. An auto-defrost feature melts this ice safely.
- Quiet Operation: Nobody likes loud humming while relaxing. Check the decibel (dB) rating. Lower numbers mean quieter running.
Factors That Reduce Quality:
- No Auto Shut-off (Bucket Models): If the bucket fills and the unit keeps running, water spills. Always ensure the unit stops when the bucket is full.
- Weak Fans: A weak fan means the air doesn’t move well through the machine. This lowers the effective drying power significantly.
User Experience and Use Cases
Think about how and when you will use the dehumidifier.
Winter Storage vs. Summer Camping
If you store your RV during winter, you need a reliable unit that can handle cold, damp air (look for those with auto-defrost). For summer use, powerful moisture removal during humid trips is the priority.
Ease of Use
Setup should be simple. Can you figure out the controls quickly? Is emptying the water bucket easy to reach? A confusing interface means you might not use the dehumidifier correctly.
Top 10 FAQs About RV Dehumidifiers
Q: How big of a dehumidifier do I need for my 25-foot travel trailer?
A: For a standard 25-foot trailer, a 30-pint unit is often enough. If the climate is very rainy or humid, step up to a 40 or 50-pint model for faster results.
Q: Can I use a regular home dehumidifier in my RV?
A: You can, but it is not recommended. Home units are often too large, use too much power, and might not handle the temperature swings inside an RV well.
Q: Is it better to use a desiccant dehumidifier or a compressor model for an RV?
A: Compressor models (the common type) work best in warm, humid conditions. Desiccant models work better in cooler temperatures, like during winter storage, but they can be noisier.
Q: How often should I empty the water bucket?
A: This depends on the humidity. On very damp days, you might empty it twice a day. On average days, once every 12 to 24 hours will suffice.
Q: Will a dehumidifier stop mold from growing?
A: Yes, if you keep the humidity below 60%. Mold needs moisture to grow. The dehumidifier pulls that moisture out of the air.
Q: Are portable dehumidifiers safe to run while driving?
A: No. Most portable units are not designed to handle the movement of a driving vehicle. Always turn them off and secure them before you travel.
Q: What is the ideal humidity level to maintain in an RV?
A: Experts suggest keeping humidity between 40% and 55%. This feels comfortable and discourages pests and mold.
Q: Do I need a special electrical cord for these units?
A: Most RV dehumidifiers use a standard three-prong plug. However, always check the power draw (amps) to ensure your RV circuit can handle it safely.
Q: Why is my dehumidifier running constantly but not collecting much water?
A: This usually means the air isn’t circulating well over the coils. Check if the air intake or exhaust vents are blocked by furniture or walls.
Q: Can I run the dehumidifier without the AC unit on?
A: Yes, you can. Dehumidifiers work independently of your air conditioner. Running them together is usually overkill unless it is extremely hot and wet outside.
