Should I Run A Dehumidifier In My Rv?

It can be a challenge to keep your RV in good condition during the winter months. One question that often comes up is whether or not to run a dehumidifier.

In this blog post, we will explore the pros and cons of using a dehumidifier in your RV and help you make the decision that is best for you!

Should I Run A Dehumidifier In My Rv?

 Even if the rig is stored it is still necessary to control the humidity inside your RV. Dry air in an RV is perfect.

 In an RV, humid air is a potential problem that could be manifested as decay, mold, and even destruction.

 The most effective method to decrease the amount of water present within the atmosphere is to utilize an RV dehumidifier.

When it comes to RV dehumidifiers, there are a few different types on the market. The most common type is the small, portable unit that can be placed on a shelf or table.

These units typically have a bucket that needs to be emptied periodically. Another type of RV dehumidifier is called a whole-house unit.

 As the name implies, these larger units work to remove humidity from the entire RV, not just one area. Whole-house units need to be vented to the outside of the RV.

No matter what type of dehumidifier you choose, be sure to empty the water reservoir as needed and keep an eye on the humidity level inside your RV.

What is the best setting for a basement dehumidifier?

The majority of HVAC engineers believe that the best basement dehumidifier is set at 40 percent. Perhaps 50% would suffice.

 However when temperatures are higher, like 90degF or 80degF the chance of growth of mold is dramatically more likely to occur.

A basement dehumidifier should be set no lower than 60 percent, according to the International Energy Conservation Code (IECC).

The IECC is a model code published by the International Code Council (ICC) that has been adopted by most U.S. states and municipalities.

At these levels, you are also more likely to have dust mites, which thrive in humid environments

Dust mites are tiny creatures that live in dust and are known to cause asthma and other respiratory problems.

If you have a family member with allergies or asthma, it is especially important to keep the humidity level in your home at a safe level to prevent triggering an asthma attack.

When should I turn on my dehumidifier?

When you are debating whether or not to utilize an air dehumidifier in winter, it is important to check the humidity levels of your home.

 If the relative humidity remains high, it may be beneficial to use your device. In reality, if the humidity is at or above 50 percent, then your space is likely to benefit from the basement dehumidifier.

If you have never utilized a dehumidifier before, it is important to note that these devices work by pulling moisture out of the air.

 This can cause your home to feel cooler than usual. As a result, you may want to lower your thermostat when you turn on your dehumidifier.

 Doing so will help offset the cooling effect and maintain a comfortable temperature in your home.

In short, if the humidity in your home is high, utilizing a dehumidifier can be beneficial.

What number do I set my dehumidifier to?

Here’s some expert advice by CR as well as Energy Star, on getting the most out of your dehumidifier. Determine the desired level of humidity.

 The ideal relative humidity is between 30 and 50 percent in accordance with Energy Star (and 30 to 40 percent in areas that are colder during the heating season).

If you’re not sure what the current relative humidity is in your home, you can buy a hygrometer at most hardware stores for less than $20.

To maintain this relative humidity in your home, set your dehumidifier to the recommended level and empty it frequently.

If your model does not have an automatic shut-off feature, unplug it when the bucket is full to avoid overfilling and possible water damage.

Also, keep in mind that portable dehumidifiers are less energy efficient than whole-house models.

If you have a central air conditioning system, consider having a whole-house unit installed.

What should I set my humidity level to?

The majority of people feel that a relative humidity of 30-60 percent is the best for their comfort indoor humidity, and the ideal indoor humidity is between 30 and 50 percent.

The ideal indoor humidity levels vary depending on the season. In the winter, it’s recommended to keep the indoor humidity level at 30-40 percent to prevent health problems such as static electricity, sinus congestion, and dry skin.

In the summer, the ideal indoor humidity level is slightly higher, between 40 and 60 percent, to prevent heat stroke and dehydration.

You can use a humidifier or dehumidifier to help maintain these relative humidity levels in your home.

Check the relative humidity in your home with a hygrometer to ensure that it’s within the comfortable range for you and your family.

What should I set my dehumidifier at in my camper?

Weather stations can provide you with an idea of the amount of humidity is present inside your vehicle.

 This is useful in managing the moisture and condensation that you might experience. The best guideline is to keep the humidity to somewhere between 30 to 50 percent.

If the humidity is too high, you might experience musty odors. You might also notice that your windows are fogging up more often. Too much moisture can also lead to the growth of mold and mildew.

If the humidity is too low, you might start to experience static electricity shocks. You might also find that your skin feels dry and itchy. Low humidity can also cause wood to crack.

The ideal setting for a dehumidifier will vary depending on the conditions inside your camper.

What should basement dehumidifier be set at?

Many HVAC engineers believe that the best basement dehumidifier is set at 40 percent. Perhaps 50% is enough.

 However at higher temperatures, like 90degF or 80degF the chance of mold growth is greatly higher.

So what is the ideal temperature for a basement dehumidifier?

The answer is that it depends on the level of humidity in your basement. If you have a lot of moisture in your basement, then you will want to set your dehumidifier at a lower setting.

If you have less moisture in your basement, then you can set your dehumidifier at a higher setting.

 It is also important to check the humidity levels in your basement regularly so that you can adjust the settings on your dehumidifier accordingly.

By following these tips, you can help to ensure that your basement stays dry and free of mold and mildew.

Should a dehumidifier run all the time?

To summarize, you should keep your dehumidifier running all day, at least twelve hours per day.

 This is a great general rule of thumb. You’re free to do this even that you don’t adhere to the same schedule each day, but you should be aware that the more frequently your family uses your dehumidifier the cleaner and fresher it will stay throughout the year.

If you have any questions about using or purchasing a dehumidifier, please reach out to us.

Please note that if the humidity levels in your home are particularly high, you may need to run your dehumidifier for more than twelve hours per day.

In these cases, it is best to consult with a professional to ensure that you are taking the necessary steps to keep your home at a comfortable level.

Should you leave a dehumidifier on all the time?

In short, keep your dehumidifier running continuously for at minimum 12 hours per day. This is a great general rule of thumb.

 You’re free to do this even that you don’t adhere to this routine every single day, but remember that the more often your family members use your dehumidifier, the cleaner and fresher it will remain all through the year.

The key is to strike a balance. If the air in your home feels too dry, then you should leave your dehumidifier on for a longer period of time.

On the other hand, if the air feels humid and sticky, then you may want to consider running your dehumidifier for a shorter period of time.

At the end of the day, it is important to listen to your body and trust your instincts. If you feel that the air in your home needs more humidity, then go ahead and leave your dehumidifier on for a longer period of time.

What is the comfort setting on a dehumidifier?

In Comfort mode the humidity is set to be between 45 and 55 percent, this is dependent on the temperature of the room.

The dehumidifier will automatically adjust its humidity output to maintain the humidity level you selected.

You may notice that the unit runs more frequently in Comfort mode than other modes because it is working to maintain a narrower range of humidity. This is normal operation for the dehumidifier.

What should the humidity be in my camper?

The majority of people prefer 35 to 55% of humidity. This is the same zone that blocks mold from having the chance to develop.

 Sabrina and I try all we can to ensure that the air humidity of our RV at or below 50%. We also utilize monitors for temperature and humidity throughout our RV to make sure that we’re staying close to that target.

There are a few things you can do to maintain your desired humidity levels:

  • Use a humidifier: This will add moisture to the air and is great for those who live in dry climates or during the winter months.
  • Just be sure to empty and clean it regularly to prevent mold and mildew from forming.
  • Place bowls of water around your RV: As the water evaporates, it will help to humidify the air.
  • You can also add a few drops of essential oil to the water for a pleasant scent.
  • Dry your clothes outside: Hang up wet towels, swimsuits, and clothes outside to dry instead of inside your RV.


Maintaining the correct humidity level in your RV is important for preventing mold and mildew from growing.

You can use a humidifier, bowls of water, or hang wet clothes outside to help achieve this.

By following these tips, you’ll be able to keep your camper comfortable and healthy for you and your family.
