Key Things to Look for 

Before you go ahead and buy your caravan dehumidifier, there are a few things that you should be keeping an eye out for. 

Space. Think about the size of your caravan. Are you in a cosy model, or one that has a massive amount of space to offer? Humidifiers are each design to handle a specific amount of space, and you will need to determine the area you want to cover before you buy. Make sure you check this before you purchase so that you make the right choice. 

Settings. Even when you are on the road, you want a model that has a few different settings. For example, a laundry setting is really helpful if you’ve got a load to dry but it’s raining outside. 

The dehumidifier will absorb the excess moisture while your clothes dry so that you can get on with your trip in peace. Additionally, sleep mode is incredibly helpful if you need it to run overnight but don’t want to be kept awake by the often loud humming of the machine. 

Continuous Drainage. This is a great option to have. You won’t need it when you are in your caravan, but it does make it more versatile so that you can use it at home too. Continuous drainage means that the tank is hooked up with a hose that then connects it to a drain or sink.

So, you never have to worry about it becoming full and needing to empty it again. It’s possible to use in a caravan but makes more sense for home use. Having this as an option just means that you can use it in multiple settings, saving you money and also creating less of an environmental impact. 

Refrigerant or Desiccant. These are the two main types of dehumidifiers, but you need to decide which one is going to work best for your home. To put it briefly, desiccant dehumidifiers work best at low temperatures (below 10C) and refrigerant dehumidifiers work better at higher temperatures (above 10C). 

Refrigerant dehumidifiers also cost less money to run, which is especially good if you end up leaving it on constantly. However, desiccant dehumidifiers models also tend to be quieter, which is good for small spaces where you might be sleeping and living. 

Finally, refrigerant dehumidifiers are often more reliable than their desiccant material counterparts. This is an important aspect to consider if you are planning on leaving your dehumidifier to run for prolonged periods of time. 

Energy Saving. Having your dehumidifier running constantly can really add up on your energy bill, and you’ll end up noticing it at the end of each month. A timer can be really helpful in this situation as you can set it to switch off after a certain amount of time. 

If you have an automatic humidification detector built into the machine, this can also be a great way to save energy. It will only switch on when it detects humidity above the levels you set, and will switch itself back off once it brings them down again. 

In a caravan, you often have a limited amount of electricity that you can use each day. Having a dehumidifier that possesses these extra features saves you a lot of energy so that you can keep your dehumidifier running when you need it. 

To Conclude

The task of finding a good dehumidifier is never easy, after all there is a lot of choice when you go to look online.

When choosing the best dehumidifier for your caravan or motorhome, you will want something that is powerful but also doesn’t use up a great deal of power.

It may even be a good choice to go with something that doesn’t require any power so that you don’t end up using your electricity on the machine.

As long as the dehumidifier removes the excess moisture from the air and keeps things like mould and mildew away, you know it’s doing its job correctly.

Plus, the dehumidifier you use in your caravan can also be used in your home.
