Dehumidifying 101 for RV Enthusiasts

Open Road

If you're an RV enthusiast and love traveling across wideopen spaces, then you need to know how to keep your RV in tip top shape. Condensation can affect your RV and if buildup occurs - which it most often does- then you need a way to keep it under control.

Lots of things can increase moisture levels. Colder outdoor temperatures, cooking, showering, washing, and even breathing can increase humidity.

This kind of moisture buildup can cause severe damage to the structure of the unit. Moist air seeps into the walls and between joints, causing them to bow over time. For this reason, the structural integrity of your traveler is at risk. Not to mention the growth of mold and mildew. We all knowhow harmful these things are. There's a lot of money invested in your outdoorvehicle, so why not protect it?

With a dehumidifier you can keep excessive moisture under control and enjoy your RV for years longer. Extend the life of your treasured vehicle and fight moisture with the best possible means.

What causes condensation?

Moisture on Leaf

Typically the weather causes condensation. Condensation isthe formation of liquid drops of water from water vapor. Usually for condensation to take place, the atmosphere must be fully saturated. In otherwords, the maximum vapor pressure has been reached and therefore must be released.

Once excessive saturation occurs, it needs a surface tocondense on. In the case of your RV, condensation collects on the ceilings andwalls. This condensation is what causes mold and mildew to grow and eventually leads to a weakened structure.

Controlling moisture isn't difficult

Invest in a dehumidifier and use it when you're traveling. There are a number of compact options available that will help. Simply plug it in and secure a proper place for the collected water to be drained. Some models include a drain hose that drains moisture directly into a sink. Some include atank that needs to be occasionally emptied.

Another product to invest in is a hygrometer. This useful utility measures humidity so you know exactly how high it's actually getting. Recommended humidity levels are between30% and 50%. If humidity levels in your RV are exceeding this point, then you definitely need a dehumidifier.

A common question associated with dehumidifying is whetheror not it can make the atmosphere too dry. The answer is no. If you use a dehumidifier when humidity levels are high, you won't experience dryness only comfort.

If you use a dehumidifier when humidity levels are already low, then it's possible to make the environment too dry. The hygrometer will take the guesswork out controlling humidity levels. You'll know exactly when to use the unit and when not to.

Storing your RV?

Parked RV

If you're storing your RV in a storage facility, in your driveway, at a trailer park you still need to control moisture. In fact, some of the worst damage can happen while the vehicle is in storage. Why? This is because you park the vehicle and then forget about it until you're ready to use it again.

It's easy for condensation to occur without even knowing it. You'll discover the damage next time you plan a trip. Water spots, swelling, and bowing will be visible to the naked eye and the damage could end up costing thousands of dollars to repair.

To prevent this kind of damage use a dehumidifier while the vehicle is being stored. There are options available that don't require electricity.

Some models feature moisture absorbing crystals that can last as long as ten years. This dehumidifying technology is called desiccant and is quite effective.

The type of dehumidifier you choose should depend on how much moisture control you need. Assess humidity levels inside your RV with a hygrometer and ask your product professional to advise you on the best possible purchase. Purchasing the wrong unit can lead to insufficient moisture control and difficulties down the road.
