10 Suggested Dehumidifiers Analyzed for 2021

Choosing the best dehumidifier for your RV won’t be easy, especially when you don’t know much about these appliances. Luckily for you, here we are going to explain all the critical factors of a dehumidifier so you can pick the perfect one for your trailer:

Dehumidifying Capacity

There are different capacities when it comes to dehumidifying, and they all change the overall performance of the product. This capacity is measured in pints every 24 hours, and it varies depending on the size of the option you want to get.

Most small-sized dehumidifiers offer between 0.5 to 5 pints of dehumidifying capacity per day. Medium-sized options go from 10 to 30 pints. And the largest ones can provide up to 100 pints of dehumidifying capacity every 24 hours.

This means you’ll need to pick something that fits your RV moisture level and the size as well. For dry trailers, we recommend small or medium products. And for semi-wet options in rainy or snowy climates, you can go for the largest ones.

Moisture Tank Capacity

It’s also critical to find a dehumidifier that collects enough moisture with little maintenance. And it all comes down to the tank capacity.

Most dehumidifiers offer between 5 and 25 pints of capacity in their tank, which is enough for medium and large-sized options. For small ones, they can go from 1 to 5 pints, sometimes even measured in ounces.

But it all comes down to picking something that fits your needs and the capacity of the product. If the dehumidifier collects 50 pints of moisture a day, go for a tank with at least 25-pint capacity, so you only have to empty it twice a day.

Otherwise, you may have to go back and forth with the product, and that can be time-consuming.

To get rid of this process, you can eventually get a self-draining option. They also have a moisture tank, but they drain all the liquid without human handling. This adds efficiency & convenience to the product.

Additional Features

There are many other features you may want to go for when choosing a dehumidifier, such as quiet operation (anything less than 55 dB is enough). Great energy efficiency is also useful, so the product doesn’t use more than 30 watts of power from your trailer.

A direct drain connection helps to get rid of performance stops or constant maintenance. And a filter indicator that tells you when to empty the tank will also be beneficial. Features such as auto-humidistat and auto shut-off will help to prevent over-working of the product.

And auto-defrost and low-temperature settings prevent loss of effectiveness in cold climates. Lastly, an auto-reset feature helps to avoid issues of power.


Both desiccant and refrigerant dehumidifiers offer excellent results and similar capacities. However, they change entirely when it comes to working in different temperatures and environments.

For example, refrigeration-based options will be more efficient and perform better in high-temperature places than others. If the temperature goes down too much, the performance of a refrigerant dehumidifier will drop down a lot.

In contrast, a desiccant dehumidifier is more efficient in cold temperatures, providing the highest performance in cool and moist environments. They work better than refrigerant in cold places, as they are made to work with a cold interior and parts.

This means that when it comes to picking the ideal dehumidifier for RV, we recommend going for a desiccant model among any other. It will help you work better inside a trailer that can get really cold sometimes.

How to Maintain a Dehumidifier

To keep your dehumidifier clean and always ready to continue working without issues, it’s essential to follow a few tips. Here we explain how to maintenance a dehumidifier working effectively:

Change the Tank Water

Make sure the stagnant water inside your RV dehumidifier gets changed at least once a day. This will prevent the growth of bacteria and other contaminants which can eventually evaporate and keep adding moisture to your trailer. Also, remember to clean the tank after emptying.

Clean the Humidifier

Whether it is every two or three days, cleaning the product consistently will prevent the growth of contaminants and bacteria outside and inside the dehumidifier. We recommend using distilled water with a soft cloth to clean all the components if possible. This will keep your product working well and free of contaminants.

Frequently Asked Questions

There’s nothing worse when picking a dehumidifier than not really knowing what you’re getting. That’s something that happens with many buyers, but here we are to get rid of that. Read these common questions and forget about doubts you could have:

Does a dehumidifier use too much energy?

Answer: There’s no real way to say that a dehumidifier uses too much energy when the truth is, they actually use too little. These appliances need meager quantities of energy to function (from 20 to 100 watts), which means they will work problem-free on any trailer.

How many times should I refill my dehumidifier a day?

Answer: Most people like to refill their dehumidifier once every 24 hours when they use it almost all day. However, we recommend doing it twice to prevent the creation or growth of contaminants and bacteria in the stagnant water. If you use the product only a few hours a day, go for once every two days.

What type of water should I use to refill my dehumidifier?

Answer: We recommend mineral-free water or distilled water. But using hard-water is still possible, but you’ll have to know that minerals in the water may eventually transfer to the air in your RV and create white dust or irritating contaminants that you could breathe.

Should I replace the dehumidifier filters?

Answer: Yes, filter in dehumidifiers tend to get filled with microbes and bacteria from the air, as well as minerals and other pollutants. We recommend replacing/cleaning them every two months.

Final Words

To get the best RV dehumidifier, there’s nothing more important than to consider all your needs and taking into account the capacities of the products you review.

Doing this will help you not only to understand better what you need to go for, but also help you pick a more reliable, efficient, and performance-oriented product. So, if you want a great machine in your trailer, start picking now!
