High humidity is a problem no matter where it is.

No matter where the area is, maintaining ideal relative humidity level is crucial to keep tons of problems at bay. Mold growth, mildew, fungal problems, bacteria and allergens, damp property, rotting wood; are a few of the many issues that come with increased moisture levels in the environment.

RV dehumidifiers are the best devices to combat high humidity levels. They come with inbuilt units that are designed to absorb the excess water vapour from the air. There are different types of RV dehumidifiers available in the market. You can choose the best option for your RV based on the extraction rate, cubic feet coverage, renewable mini dehumidifier or desiccant models, the functionality of the unit in different temperatures, etc.

Here we have a list of the best RV dehumidifiers available in the market that will deliver excellent performance at maintaining relative humidity. Find out which is the best dehumidifier for your RV by doing a good research into the products and their features.

Should I run a dehumidifier in my RV?

Humidity in RV

Yes! It is highly recommended that you run a dehumidifier in your RV. Just like homes, RVs are equally prone to high levels of moisture and humidity. A damp environment inside your RV will bring damage to property and health. There are many RV dehumidifier models to choose from in the market. You can look into renewable mini dehumidifier models, portable dehumidifiers, silica gel beads, or any kind that best suits your need and comfort.

What size dehumidifier do I need for my RV?

The size of the RV dehumidifier that you require depends on two main factors. The size of the RV and the amount of dehumidification required. It has been estimated that large RVs have maximum square footage of 400 feet. For this capacity, a smaller dehumidifier would do the perfect job. A typical large home model, like a 70-pint dehumidifier, would certainly be overkill (even for larger RVs).

How to choose the best dehumidifier for your RV

Choose the right dehumidifier

Choosing the best dehumidifier for an RV cannot be done in haste. It requires observation and planning, just like how you would treat your house. Before you begin looking at the best dehumidifiers on the market, you must first look into your RV. Here are some important factors to consider before purchasing a dehumidifier for an RV.

Humidity level:
What is the level of relative humidity a dehumidifier is expected to deal with within the RV? this is the basic foundation for getting the right unit. The moisture extraction rate you aim to cover must be possible by the unit too.

Size of the RV:
How big is your RV and what is the layout? This is the second most important question. The dehumidifier you purchase must be equipped to cover the entire space of the RV, in the right measure. It should be neither be too much or too little. A high capacity device can dry out the air too much make it extremely dry. On the other hand, a low performing device cannot remove the excess amount of moisture in the atmosphere. For example, a 70 pint dehumidifier is not necessary for a small space. Even of the features list on this 70 pint dehumidifier are hard to resist, you cannot go with that option.

Condition
If there is pre existing damage that has to be attended to immediately, you must have dehumidification done in accordance with that. If the RV experiences fluctuating temperatures, for example, that is when you have to look deep into the features that will best suit a condition like that.

Features
This again is based on the requirement you have and the price you can shell into it. There are different kinds of dehumidifiers and the one that best suits your need must be the one you settle down with.

How do I keep the humidity down in RV naturally? 4 simple ways to try

RV with children

Here are 4 simple ways you can try that will help to keep the relative humidity in the environment of your RV under control naturally. Although it is recommend that you use a dehumidifier, these are some small steps that can help in keeping humid air away.

1. Ventilation
This is probably the foremost thing to help with dense air. Ensuring there is plentiful room for air circulation will help you to keep condensation away. This is what you can do:

★ Have a window opened.
★ Remember to open or turn off the roof top vents or fan when you take a shower or when you cook.
★ Always keep the lid of the pan or pot on when you cook. This will help to keep the heat in.
★ You can opt to cook outdoors as and when possible.
★ Avoid drying any damp clothes in the RV as much as possible.

2. Invest in double-pane windows
Double pane windows are definitely a better choice in comparison to single pane windows. These will insulate your RV and keep the temperatures indie the RV warmer than the one outside. You will be able to avoid condensation this way, which occurs due to change in temperatures.

3. Keep the floor warm
Avoid building in more water vapour inside the RV and find ways to keep the floor warm. You can avoid spills or get rid of them at the earliest, insulate the floors with carpets, etc.

4. Use an air conditioner
Although an air conditioner is not designed to effectively or actively remove humidity from the air; it certainly does cause a change in the existing temperature. When you have cool air being circulated inside the RV, you will experience lower humidity.

Types of Dehumidifiers for RVs

The two types of dehumidifier models are Refrigerant models and Desiccant dehumidifiers. The two models or dehumidifier types do have their own share of pros and cons. You can choose desiccant dehumidifiers or compressor dehumidifiers based on which will assist your need best. Let us look briefly into desiccant units are different from refrigerant models.

You should know that desiccant models are rechargeable, which is a key feature many owners look for. Here are few other highlights of a desiccant dehumidifier. Their ability to give powerful moisture removal in enclosed spaces will ensure the area is free from mold, mildew, fungal growth, and a damp environment, they generate minimal noise, they have a lightweight profile. A desiccant dehumidifier comes with a highly efficient unit that can continue to function seamlessly even when temperatures drop below 33 degrees Fahrenheit.

Desiccant models are been appreciated for their design that blows hit air across the RV. This will keep the RV warm at al times. The cons of a desiccant dehumidifier would be; it can be very expensive investment which not everyone can afford, and just one desiccant dehumidifier might not be sufficient terminate the humidity problem that persists in your RV (more than one unit might be required).

Compressor Refrigerant Dehumidifiers:

Refrigerant models is comparatively cheaper than a desiccant dehumidifier. Moreover, a refrigerant unit is said to have higher extraction rate for lower power consumption. If you opt lean towards refrigerant models for your RV, you can be guaranteed that just one device is sufficient to cover the entire area. Your RV will be free from moisture and from mold. The downside t getting a refrigerant unit is that it might not be efficient in its functioning when temperatures drop below 41 degrees Fahrenheit. These units are also noisier when compared to desiccant dehumidifiers. If you suspect that temperatures dropping under 41 degrees Fahrenheit is going to happen often in your RV, you may want to reconsider this option.

FAQ Section

1. What happens if the humidity is too high in RV?

High humidity in an RV can cause serious damage to health and property. Mold is one of the major problems that arise from high humidity. If this has been the case, you might notice that the wood on the sub flooring, walls, and cabinets will slowly begin to swell, rot and deteriorate if left unattended.

2. What causes mold in RV?

Mold growth stems from mold spores. These are naturally present in the environment in dormant conditions. When they find the favourable conditions, like a moist dark place, they will slowly begin to grow. When an RV is being stored, it offers the moist and dark place. All the moisture that its trapped inside the RV will soon give rise to mold.

3. Is it safe to run a dehumidifier in RV constantly all the time?

It is safe to run a dehumidifier constantly, but it must be done when necessary. You can run your dehumidifier when the humidity level shoots above 50 percent. There are other ways to keep humidity at bay, naturally, as discussed above. You can pout those methods into practice to avoid using a dehumidifier at all times.

4. Does DampRid work in RV?

DampRid is incapable of creating air flow for dehumidification, unlike a dehumidifier. You must remember that the volume of air that exists inside an RV is too high for DampRid. It cannot be as effective as a dehumidifier could. However, DampRid can be used for certain area in an RV where there is restricted airflow (perhaps under the sink, in the shower, etc.).

5. What should the humidity be in my RV?

The ideal relative humidity level is recommended to be within 30% to 50%.

6. What are RV crystals?

RV crystals are moisture absorbers. They can be used to eliminate condensation (on windows, walls, ceilings), musty smells and mold. These are best out into use when an RV, trailer, or camper is sent to long periods of storage or lay-ups. These crystals can be used to keep the interiors moisture free during these periods.

7. How to keep moisture out of RV in winter?

Here are some simple tips to keep moisture out of an RV during winters.
» Check how you can insulate RV slide-outs.
» Use a dehumidifier as and when required.
» Temperatures indoors can be increased.
» Make use of vent fans.
» Avoid using gas furnace and hanging things to dry within the RV.
» Try opening a ceiling vent or window.

8. How to stop condensation in RV?

Condensation in RV can be prevented either by following the list of steps mentioned above or by using products that help in moisture-control. RV crystals, DampRid, and dehumidifiers are the best among them. Keeping the inside of an RV warm, insulating it, creating some space for ventilation, and avoiding activities that increase humidity within the RV will ensure the space is free from condensation.
