Best Small Dehumidifier for RV Reviews

A major problem that is not usually seen at first is the air moisture when living in an RV full time. You can measure the air’s humidity level and you will discover that RV living needs a dehumidifier. When the level of humidity in the air is high, things are not going to dry up as quickly as you want it to and when this is the case, mold buildup is very common and will increase.

When there is low humidity, the AC unit is going to help in removing air moisture. However, when it is cool or if it is winter in the southern part, there has to be an alternative to getting rid of moisture. If most of the air goes through condensation and goes into the joints, it can lead to major damage to the structural integrity of the RV. Due to the constant showering and cooking being done in the RV, there is a possibility to get a lot of mold fungus growth without you knowing it. That and living in climates that have high humidity only makes the situation extremely damaging to your RV.

Things to Consider Before Buying Small Dehumidifier for Your RV

1. How a dehumidifier protects your RV

RVs experience a lot of humidity because it is always outdoors for a long time. The major factors that cause humidity are washing, cooking, and changes in temperature. All of these are contributors in the RV’s body because damp air stays on the walls and lead to extreme damage, which affects the whole structure.

2. Make sure it is for RVs and not for houses

An alternative to keeping moisture levels low is using an electric dehumidifier. There are a lot of them you can buy, but remember that you need to choose one that is only made for RVs, or pick a small one because the standard ones made for houses are too large for motorhomes.

A small dehumidifier can collect about 1 liter and there are some that are good for 2 liters and these are the medium-small ones in size. What you pick will depend on your surroundings and the dampness of the area.

3. Why get a dehumidifier

They are small and really simple to use because even first-timers never have trouble using them and ae very efficient in keeping humidity level low. If you have pets, there is nothing to worry about because no harmful chemicals are included. If you have been using replacement crystals, owning a dehumidifier will save you the trouble of constantly buying them again.

4. The way dehumidifiers function

Condensation happens because of water vapor formation that seeps in and goes to the environment while the temperature has reached zenith. This moisture is going to the walls and the structure of the RV and this is where mold and mildew come from. Ultimately, the RV’s walls and interiors are the most affected by the high humidity.

5. When is it time to place a dehumidifier in your RV?

You can place the dehumidifier anywhere inside the RV. The only consideration you need to make is the safety. This is because a dehumidifier has toxic chemicals, which you need to make sure that it is located in a safe place where it will not get knocked over.


6. Where you should put the dehumidifier

The usual areas where dehumidifiers are stored are the gravel area, garage stores or shelter facility. Although, these places are prone to mold and mildew because of high humidity level in the environment. However, the garage store does not have the same moisture factor because their spaces and packed and there are outlets where air can enter. While gravel areas and open spaces or parking lots are prone to excessive moisture compared to a garage store.

7. Look for these when buying a dehumidifier for your RV

It should be small and contains everything you need, it should be spill proof because you will be wasting water and functionality if it is prone to spilling. The dehumidifier should not be toxic and non-corrosive. The dehumidifier has to be renewable to lessen waste and expenses.
