Damp is a word that can strike fear in any caravan owner. After all, it can shorten the life expectancy of your caravan, with the dreaded mould and mildew following. While good ventilation is the best way to combat this, having one of the best caravan dehumidifiers can help on a shorter-term basis.

Caravanners are going to want to do everything they can to keep damp out of their tourer, with water ingress capable of causing serious damage. Having the best caravan moisture meter can help you detect a problem before it becomes a serious issue, but a caravan dehumidifier can also play a crucial part in drawing excess moisture out of the air.

When you’re thinking about a dehumidifier for a caravan, there are a couple of different options to consider. Models that operate on electricity will be able to absorb more moisture from the air, which may be a practical option if you’re storing a caravan at a facility that lets you use electricity. However, while they come with auto-switch off functions when the tanks fill, you’ll still need to go and empty them. Then there’s the running costs to factor in as well.

There are cheaper options available too, which use crystals or tabs to absorb moisture. Models such as the Unibond Aero 360 Moisture Absorber that we’ve included in this guide require tabs to work, and once they’re set up, will need changing every one to three months, depending on the product. They’re also likely to be less effective than the electrical caravan dehumidifier options.

There’s plenty to consider when you’re looking for the right one, so to give you a helping hand, we’re running through our top picks in our best caravan dehumidifier guide.

The best caravan dehumidifiers:

Unibond Aero 360 Moisture Absorber

UniBond Aero 360 Moisture Absorber

Reason to buy:

  • Compact, operates silently, requires no power

Reason to avoid:

  • Tab need replacing

We think UniBond’s AERO 360 Moisture Absorber is a useful dehumidifier to try when you’re looking for a way to combat damp and unpleasant smells in your caravan. As it doesn’t take up too much space, it should be worth considering for use even for those who have a small caravan.

The non-electric option is budget-friendly, although you will need to buy tabs for it from time to time – each refill should last for up to three months. You’ll be able to keep an eye on when the tab needs changing, thanks to an indicator.

The lightweight and portable product encourages 360 degree air circulation, and we like how easy the spill-safe dehumidifier is to operate too.

Pro Breeze 1500ml Dehumidifier

Reason to buy:

  • Automatic shut-off, operates quietly

Reason to avoid:

  • Requires electricity to operate

Unlike some of the options on our list, this caravan dehumidifier requires electricity to operate, running on 40 watts.

However, what this gets you is a compact product that is capable of absorbing up to 500ml of moisture from the air each day into its 1500ml tank. If the tank does fill up, it will automatically shut off, letting you know that it needs emptying. Then there’s the thermo-electric Peltifer technology – this means the device operates incredibly quietly, so you remain undisturbed while it’s running.

We like that it’s easy to manoeuvre too, weighing only 1.85kg.

Meaco Portable Dehumidifier DD8L

Meaco Portable Dehumidifier DD8L

Reason to buy:

  • Works well in lower temperatures, powerful

Reason to avoid:

  • Most expensive option, only likely to be needed in extreme cases

If your budget will stretch to it, this option from Meaco is definitely worth considering. Coming with a two litre tank, it can extract up to 7.5 litres a day, and will help you keep moisture to a minimum in your caravan.

It’s packed full of useful features – for instance, it will automatically turn off when the tank is full, and comes with an anti-bacterial filter and ioniser to provide you with cleaner air.

Another feature we like is that the fans will run for five extra minutes to make sure the target humility is met, before turning off for 30 minutes. It will then test the air again, and if all is well, it will turn off for another 30 minutes.

The desiccant dehumidifier will be ideal for keeping on top of the moisture when your caravan is in temperatures that are below 10C too.

Kontrol Streamline Moisture Trap

Kontrol Streamline Moisture Trap

Reason to buy:

  • Noiseless, doesn’t require electricity

Reason to avoid:

  • Replacement granules will be needed

This moisture trap from Kontrol is simple to set up, simply requiring a pack of crystals to be added to the tray. Then, after placing it in your tourer, it should get to work on absorbing the excess moisture in the air.

We like that they’re easy to set up and efficient on space, as well as providing a budget friendly way of keeping moisture down in your tourer. The brand advises checking the trays twice a month, as you’ll need to refill it when the granules are dissolved.

Pro Breeze 500ml Premium Dehumidifier

Pro Breeze 500ml Premium Dehumidifier

Reason to buy:

  • Small and compact, runs quietly

Reason to avoid:

  • 500ml tank will need emptying fairly regularly

We think this could be a good option for caravaners with a smaller tourer who may not have the space for a larger electric dehumidifier. Providing a 500ml capacity, it has an automatic shut-off feature to provide peace of mind, while we like how it should operate quietly in the background thanks to its thermo-electric Peltier technology.

It’s capable of absorbing as much as 250ml of moisture each day, so it should provide a relatively effective way of extracting moisture from the air. However, this means you would need to empty it every other day before its auto-shut off feature comes into effect. We like how it’s also very lightweight, coming in at only 1.04kg – this will make it ideal for moving around your tourer as required.

Ansio Dehumidifier pack of five

Ansio Dehumidifier Pack

Reason to buy:

  • No electricity required to operate, simple to set up

Reason to avoid:

  • Will need replacing

Available in packs of five, 10, 20 and more, this set of dehumidifiers are simple to set up and can absorb up to three times their weight in water. Lasting around four to six weeks, the portable dehumidifier comes with crystals that have been formulated to attract moisture from the air.

The brand advises that it will take between one to three weeks for the first drop to appear, but after setting up, it will be able to absorb as much as three times its own weight.

ANSIO Wardrobe Dehumidifier Hanging Bags

ANSIO Wardrobe Dehumidifier Hanging Bags

Reason to buy:

  • Ideal for use in smaller spaces like wardrobes

Reason to avoid:

  • Will need replacing

Coming in packs of three, six, 12 or even 60 if you want to stock up, these reasonably priced hanging dehumidifiers are different to the majority of options to feature in our caravan dehumidifier guide. What we like about them is how they can be hung in your tourer’s wardrobes or cupboards to start absorbing moisture.

Coming with hydrophilic crystals, the brand says they should last for between four to six weeks. The hanging bags are capable of absorbing up to three times their weight in water, with the first drop typically appearing after four to seven days, based on how humid the space is.

How to choose the best caravan dehumidifier

A good caravan dehumidifier can help to play a part in the battle against water ingress, so it is a buy you will want to get right. The biggest decision when you’re choosing the one for you is whether you want it to run on electricity or would prefer a non-electric option.

The advantage of an electrical dehumidifier is that it will be able to draw a lot more moisture from the air than a non-electric option. We reckon these make a useful choice for those who use storage sites where electricity is provided. However, the downside is you’ll have to consider the running costs and you’ll have to be able to empty the tank once it’s filled, even if there is an automatic switch-off.

Then there are non-electric options. The advantage of this type is no electrical power will be required to operate – instead, they rely on tabs or crystals to draw the moisture out of the air. They’re also a more budget-friendly option and are generally more compact too, with one of the choices in our guide perfect for use within a wardrobe, for instance. However, you’ll need to remember to go and change the tabs or crystals around every four to 12 weeks, if not completely replace them, meaning you will still require access to your van to do so.
