Where to Place Dehumidifiers in RVs and Cars

Buying the correct dehumidifier to suit your requirement is important. But what is more important is to place it strategically so that you can use it to the maximum capacity. A range of portable dehumidifiers is available in the market that can be placed anywhere in the building or your vehicle where there is high moisture. In small cramped-up spaces such as RVs and cars, it might get difficult to find the right place to keep your little machine. Especially, if they’re non-electric, the importance of placement increases. To tackle this issue, we’ve come up with a list of locations in your RV and your car where placing the dehumidifier will yield effective results!

Where should you place the dehumidifier in your RV?

In RVs, there’s a lot of space to position dehumidifiers, unlike your cars. So, it might be a task to search for the most convenient place. We’ve carefully noted down the best places in the RVs where placing a dehumidifier will yield maximum results. You can place your dehumidifier in the following places:


There’s barely any place that is moister than a bathroom. When you use hot water, it increases the humidity in the room. The vapours will settle onto your bathroom items and accelerate the growth of mold. If you don’t have a powerful exhaust fan, it’ll be difficult to quickly release this humid air into the open. Dehumidifiers placed above the vanity or the sink will assist in ventilation and reduction of humidity. The countertop is ideal as it is elevated and has enough space for a small dehumidifier to be placed without a disturbance.

Living Room

This is the place where we sit mostly to eat, watch television and pursue many other leisure activities. To ensure our personal comfort, a dehumidifier over here will surely work wonders! Moreover, it will protect our expensive couches!


The closet is the place with maximum risk of catching mold. We keep it closed at all times and it’s dark inside… ideal for all the fungus to grow! Especially in humid places, you might have noticed that if you keep the clothes in the closet for over 2 months, they become moldy… And we don’t want that, do we? 


After the bathroom, the next place where water is used in plenty and there’s a chance of the room being moist is the kitchen. Additionally, if you’re someone who enjoys elaborate cooking, the dehumidifier can help reduce the pungent odour that is produced when stale food or unwashed vessels are kept lying around the kitchen for a long time. Placing a dehumidifier here will have a dual function. It will prevent the food from decaying fast and will also provide you with comfort.

Driver’s Cockpit

This is quite a thoughtful area for the placement of a dehumidifier as it will help in defogging your windshield quickly. This is especially true if you do not have defrosters for your windshield. It will help you stay comfortable in while driving as well. 

In case you don’t feel the need or simply do not wish to keep the dehumidifiers in these places, we’ll tell you where else you can keep your dehumidifiers in your RV: Front and Rear Living Areas as well as Storage Compartment near Water Tank.

The Best Place To Put a Dehumidifier In The Car?

If you’re using a dehumidifier in your car for the first time, you might be a bit confused about its placement. If you’re wondering, where should you keep in your small sedan or even your SUV, here are some locations that we’ve carefully selected for the best outcomes!


There are various reasons why most people prefer to keep their dehumidifiers here. This is the most common place where you can place your dehumidifier with almost no hindrance to the driver. Also, it will be quite easy to control the device from the driver’s seat or even the passenger’s seat. Moreover, it will ensure quick defogging of your windshield.

However, if you’re not quite comfortable with this location, we’ve still got you covered!

Center Console

The centre console of your car can be an ideal location for the dehumidifier. We recommend using electric humidifiers in cars as they’re quite efficient and compact. The centre console is usually undisturbed and has enough space, even in the most compact sedans, for a mini dehumidifier. 

Car Trunk

Since the trunk stays separated from the rest of the car interior mostly and is closed at all times, there’s a greater chance of mold growing here. Especially, if you store your shoes or boots and other such items, mold will be a nuisance here! To avoid that, using a compact dehumidifier here will serve its purpose without occupying much space. 

Rear Windshield Shelf

If you don’t have a rear window defroster, placing your dehumidifier here will help defog your rear window quickly! Sometimes, the dashboard doesn’t have enough space or you personally prefer keeping the dashboard decluttered. In such cases, the rear windshield shelf is the perfect location. There’s plenty of space here to place the dehumidifier without compromising on the aesthetics of the car and the view of the rear for the driver. 

We’ve summed up all the locations where keeping dehumidifiers would ensure effectiveness and provide no hindrance to your work either. You can use both refrigerant and electric dehumidifiers in these spaces with no inconvenience at all.
