Best RV Dehumidifiers

The Best RV Dehumidifier

An RV can be a great way to travel, especially if you love escaping to remote locations that require road trips and many rest stops.

The only issue that comes into play is when you end up staying on the road for an extended period of time.

Let's face it, even if you're out on the road, you're still stuck in an RV which has limited space. This means that you'll be cramped in an RV with stuffy air that may be dry and wreak havoc on your respiratory system.

A dehumidifier can help control the humidity within your RV, making it a better living environment. The only question is, what is the best RV dehumidifier?

RV Dehumidifier Buyer's Guide

The dampness that accumulates in an RV can be a real problem, but there are many solutions to help with this problem. The most effective way is by getting a dehumidifier for your RV.

Dehumidifiers can help remove extra moisture from the air. This can reduce bacteria, mold, and other odors from accumulating in a poorly ventilated vehicle. Listed below are a few things you should consider when deciding to purchase a dehumidifier for your RV.

Benefits of RV Dehumidifiers

There are many benefits to owning an RV dehumidifier. Many people don't believe that they offer much use in an RV because the RVs can usually be ventilated. But the truth is, ventilating your RV doesn't get rid of the excess moisture in the air.

Think about it: When you use the faucet or the shower in your RV, where does the moisture travel? It travels directly into the surrounding areas such as the walls, furniture, and any other objects. This can lead to the growth of bacteria and mold, and even mildew. 

Don't waste your time worrying about how effective a dehumidifier is, but instead buy one before your RV has permanent moisture damage. This is extremely important when you're traveling to humid areas with high temperatures, as these climates harbor bacteria growth and mold.

Absorb Moisture

You'll find that your RV can end up accumulating excess moisture from the outside environment. This can harbor unwanted bacteria and odors that can be harmful to humans if not taken care of. A dehumidifier can help get rid of this excess moisture by absorbing it.

Spills

Sometimes there will be an accident, and you will end up spilling a liquid of some kind. You need to remember that you're in an enclosed space and all the moisture that's left over can start to turn into mold and mildew. A dehumidifier can help absorb the residual moisture that your towel doesn't pick up.

Pets

Pets release bacteria and dander into your RV. While you may love traveling with them, it's no secret that taking them along on a trip can end up causing the place to smell. A dehumidifier can work to get rid of these odors and help create a better living condition for both you and your pet.

Storage

When your RV isn't in use, chances are you're going to use it as a storage unit. If you're trying to keep your RV in the best possible condition, a dehumidifier can help prevent the buildup of molds or bacteria that lurk around on objects.

Odor and Stink

Let's be real, if you're traveling with your family, then you're going to be dealing with some heavy B.O. from time to time, especially if you're traveling during the hotter seasons. No one likes smelling sweaty clothing or stinky shoes from summer vacation.

 A good way to help this is by getting a dehumidifier and placing it close to these objects. You’ll also be faced with odors from cooking, grilling, and other food sources. Sometimes opening the window and venting out the RV just isn’t enough.

Things To Consider Before Buying an RV Dehumidifier

Listed below are a few things you should consider before purchasing an RV dehumidifier;

Choosing a Type

The very first thing you should do is determine what type of dehumidifier you will need for your RV. Most of the time, dehumidifiers are designed to be used either at home or in the office. This type is called a refrigerant dehumidifier, and it works to condense moisture that is in the surrounding area.

The second type is a desiccant dehumidifier. This works by absorbing water when the air passes after being pushed through a rotor. They are often smaller and will only work in a single area of an RV.

What Size

There are a few factors that are going to impact what size dehumidifier you will need. If you're operating a larger luxury RV, chances are you're going to need to choose a dehumidifier that covers a larger area. If you have a smaller RV, you can get away with having a smaller dehumidifier.

Also, decide how many dehumidifiers you're going to need. Are you just having one in each room? Or are you expecting one dehumidifier to work for the whole RV? These are all questions you need to ask yourself if you're going to invest in an RV dehumidifier.

Extra Features

One way to choose the right dehumidifier for you and your RV is by looking at the different key features of each product.

One of the most important actors is to have an auto-shutoff feature. This ensures that you're RV won't get overheated and also ensures that you won't be using more energy then needed. Another feature you should look for is one that prevents the unit from tipping over. This is especially important if you're going to be using it while you are on the road.

There should also be a feature that can automatically detect what the humidity level is in your RV. Many products offer you the option of a digital display which will tell you what the current humidity is in the room. It can also tell you when the unit needs to be turned off and when the optimal humidity level is reached.

Another feature that you may want to keep an eye out for is an LED or light notification. This can help notify you if the tank is full or if it is empty. This can be useful to prevent an accident from happening or to help ensure the optimal function of the dehumidifier.

Lastly, think about the portability of your dehumidifier. Do you plan to move the unit into the current room you're occupying? Do you plan to leave it in one area? Are you going to have one for each room? If you're expecting to move the dehumidifier, then you should focus on looking for a unit that has wheels and handles to make it easier to transport it around the RV.

Noise

One of the best features you can find in a dehumidifier is one that has a quiet operation. If you plan to use the unit in your RV, you're going to want a unit that doesn't produce much sound, especially if you're choosing to use it during the night or during times when you're trying to relax.

Many old dehumidifiers can produce a loud crackling sound, which may be irritating to someone who doesn't enjoy excess noises. There are many new technologies that are whisper quiet and are barely noticeable.

Warranty

A warranty can be very beneficial to anyone who is purchasing a device online. The standard manufacturer warranty that comes with the unit will usually last up to one year after the purchase date.

While this can be useful, it doesn't mean you won't find yourself running into other issues with the unit over an extended period. This is where an extended warranty comes in handy. Many companies offer more than a year coverage, and you can usually get free repairs and replacements if the device is defective.

If you're lucky, you can find a unit that has a money-back guarantee, though this usually will only last a total of 30 days. This means that if you're not completely satisfied with how the unit is functioning, you can get all of your money back.

Tips For Maintaining an RV Dehumidifier

Here are a few different tips that we can offer you on how to maintain your RV dehumidifier;

Correctly Size

Always make sure that you're purchasing a dehumidifier that can fit the area you want to place it in. If the dehumidifier is not large enough, you may see no difference, and if you choose to use a dehumidifier that is too large, you may risk the area becoming too dry and the unit overheating. Many dehumidifiers will list the area that they can be used in.

Secure

If you're going to be using the dehumidifier while you are driving, you're going to want to make sure that the unit is secured at all times. You can buy a unit with sides on it, or you can secure it by using tape or other materials. If you don't secure the unit, you could risk the dehumidifier tipping over and becoming a dangerous hazard.

Clean

If your unit or the filter needs to be cleaned, make sure that you follow the manufacturer's cleaning instructions. This can help reduce the chances of the unit malfunctioning and also allow it to function at its optimal performance.

Unplug

The unit can sometimes get too hot, and this can become a fire hazard. Although this is very rare, this doesn't mean that it can't happen. You need to be prepared and check the unit and make sure that the temperature is not too hot. Many units come with a digital display that will help alert you if anything is wrong, but older models lack this feature.

Conclusion

In conclusion, a dehumidifier can be one of the best ways that you can get rid of excess moisture in the air of your RV. While you're traveling, you're going to be exposing your RV to extra moisture through weather conditions, food, cooking, storage, and many other factors. You're also going to be building up other odors that get trapped in your RV's interior.

To help combat these issues, a dehumidifier can help reduce the amount of residual moisture within your RV and thus prevent the buildup of mold, mildew, and odors. This is important when you're taking long vacations, as you don't want to be living in an RV that is hazardous to your health.

Create the best environment for both you and your family, as they will thank you during the trip. Remember, a dehumidifier can help prevent the buildup of bacteria and any other problems, thus saving you money in the long run.
