Features To Look Into When Getting A Dehumidifier For Your RV

What is the capacity of the tank?

You need to be able to guess a bit here since you won’t be able to come up with a precise number. If you already have a dehumidifier, try to compare the strength and the size of the room to those that you’re currently looking into. The greater the humidity, the bigger the tank should be. It doesn’t add too much on weight either, which means that it’s better to go up and be safe. 

Do I need a drain hose?

Some of these have a drain hose or a pump that lets you continuously drain the dehumidifier out. With an RV, we don’t recommend that because it’s usually not needed and it can even be a bit tricky to use it during your travel time. 

How much space do I cover and how much do I have?

Here we reflect on two things – number one is the number of square meters or feet than need to be covered. You can see how much a gadget can cover in its description and you should compare that to your estimate of your RVs size. Don’t forget to think about where you’re going to put it and how big the actual dehumidifier can be. There are people that completely forget about this and they get a big one that doesn’t fit the space that’s meant for them, which means it either goes to waste or you need to „remodel the RV a bit“. 

Performance and noise

Since you’re traveling with your RV, this means that you can run into unpredictable situations when it comes to the weather. Constant rain or snow is not something you want on your path, but it can happen. That’s why you need to go for a strong and efficient dehumidifier. 

When it comes to noise, make sure that it’s around 40ish decibels at most, because anything higher than that may annoy you and create you trouble in the time when you go to sleep. Also, you know the rule – the lower the number, the better. 

Extra stuff

Yeah, these are pretty much the features that we don’t exactly need, but they’re really cool and practical to have. The automatic shut off function is one of them, as well as the option where your dehumidifier remembers the last settings you put in. If you can change the speed of the dehumidifying or the level if you can use a pretty user-friendly interface and still make sure that it’s quite simple… You probably hit the jackpot!

What Is an RV Dehumidifier and How Does It Work?

If you know what a dehumidifier is, then you know what an RV dehumidifier is. It’s really not that much of a difference. A dehumidifier is a device that removes excess moisture from your air and provides you with a better daily life. 

An RV dehumidifier is a dehumidifier that’s lightweight, portable and ideal for your traveling phases. It essentially just extracts the water from your air and saves it into a small tank that you empty out when it’s full. 

It’s either water-soaking gels or silicones that take them in or mechanisms related to pressure or temperature. There are dehumidifiers that also filter your air, but those are a bit more pricey as well. 

There are two types – a desiccant and a refrigerant. The refrigerant is probably a better option for homes and RVs since it’s a stronger mechanism. The desiccant can be used for wardrobes and very small spaces only. 

Benefits of Using an RV Dehumidifier

As we’re approaching the end of our talk about dehumidifiers for RV, you probably want to know what are these best RV dehumidifiers supposed to protect you from. Well, we’re going to list some of the positives and you can be the judge to whether you want this change in your life or not. 

No more smelly rooms

When moisture gets trapped in a room, whether it’s in your home or your RV, it starts to create this stale, musky smell. Many people describe it as the smell of old things, but it’s surely not something you want to inhale daily, especially if you see your RV as a way of getting away from stress and anxiety. 

Stop the corrosion

RVs have metal parts that can easily rust if they’re in contact with water. Over time, things usually get rusty, even if we don’t really expose them to liquid. This is the result of air with a lot of moisture constantly being in and around the RV. If you want to save cash and not pay for the next paint job, get a dehumidifier and place the RV in a dehumidified garage. 

Make the RV last a lot longer

Don’t forget that a lot of mechanics that go on in the RV are also made of metal, and it’s also prone to rust. It’s much smarter to prevent these issues than it is to try and fix them when they happen. 

Stop fabrics from deteriorating

The thing about fabric is that it never really becomes dry if it’s exposed to moist air. It will always be „semi-wet“ and have this weird feeling to it. This leads to bacteria and weird smells, but also makes the fabric break much easier. 

Make your wooden furniture pay off

Wood is also one of those things that don’t really do good under exposure to moisture. It starts to rot and peel away, which means that you’ll probably have to invest more in it later or simply throw it away. Why, if there is a possibility to prolong the lifetime of a single piece?

Better health

Bacteria, viruses, spores, and cysts all love humid spaces. Mold and mildew as well. Those who usually have respiratory issues easily feel a difference when you start to use a dehumidifier. It’s like they can finally breathe and they don’t cough as much anymore. You also don’t have to be worried about immunocompromised family members such as kids, pets and elders. 

Why Do You Need an RV Dehumidifier?

If you want to be healthier, but also prolong the lifetime of everything in your RV and the RV itself, you really should get a dehumidifier. Most people see this as an investment, and so should you, because you will finally be able to spend that stress-free and guilt-free time in your getaway dream RV. 


Now that you know everything you need to know about dehumidifiers, RVs and dehumidifiers in RVs, we leave you to check out the list and to see which models may be the more appropriate ones for you. If you think that you need to learn a bit more, do so and come back, but we’re sure that this is pretty much all the information you need. Good luck!
