Dehumidifiers for Boats, Caravans and Cars


superdry dehumidifier pack


When the winter season starts, the thought of everyone is always on how best to protect their motor home or caravan from mould and damp. Mould is a leading enemy and it loves the damp, stale air found inside a caravan that has been abandoned for winter.

Having good ventilation is fundamental to prevent the air from going stale. However, moisture can require some additional help to keep it far away. For instance, on a moist day, the air entering into the motor home or caravan via the ventilators will be damp and this will condense on cold surfaces.

The ideal solution to this is a power-driven dehumidifier. It keeps the interior dry while preventing mould growth. There are two types of dehumidifier for this; the compressor models and those that make use of a desiccant to dry the air.

You will need to opt for a machine that possesses the extraction ability to handle the air volume in the caravan, but the most essential feature is that the unit be able to work at low temperatures.



Your caravan, mobile home or boat is likely filled with expensive top quality finishes like fabrics and wood.

These materials are very vulnerable to humidity. Caravans and boats are usually left for several months, sealed and even unventilated for a long time. If a de-humidifier is abandoned, damp air will be trapped inside, resulting in that familiar moist, mouldy scent, alongside fungus and bacteria. If left unattended to, your wooden finishes will be stained and soft fabrics begin to develop mould and will finally rot. Without a de-humidifier, it would be very difficult to watch over and regularly be there to keep things aerated.

A de-humidifier will get rid of the humidity of a sealed caravan boat and feed into an outside drain or reservoir tank, successfully removing all humidity from the air, while also keeping your boat damp- free. Such finishes will swiftly worsen and become stained even after a short time period. Dehumidifier units that are handy can be used to dehumidify any interior, either small or large. Additionally, because power cuts are inevitable with these vehicles, the dehumidifier comes with an auto restart in case the power cuts.


Getting in the car during the winter months for an early morning commute is an even nastier affair. Apart from cleaning the frost on the external part of the car, most times we are greeted with mouldy smells and condensation on the inside. Attempting to clear a windscreen of ice when it is on the inside is principally irritating.

Moisture possesses an ill-fated ability to be able to discover a way past door and boot seals, most especially in older vehicles. Mould growth and dampness is a sure way to damage car’s upholstery, therefore it is a thing that should be handled.

There are two basic ways to dry out your car’s interior; it can either be carried out via an electronic dehumidifier that works from your 12V cigarette lighter plug or via humidity absorbers, which is also described as ‘moisture traps’. These moisture traps work surprisingly well by holding about 125ml of water.

If you have a decent-sized boot to stand it in, you simply buy a standard dehumidifier for the home and use an extension cable to run it into the car. You would need to ensure that the car interior was quite sealed for it to function.

Furthermore, there are dehumidifiers that work on the 12V power outlet in your car. By far, the most admired of these is this dehumidifier that comes with the relevant power adapter that has already been supplied. However, the issue with it is that clearly the car must be running for it to work. Whenever they are working, they will strip dampness from the air very fast compared to any other moisture trap.

Dehumidifier uses in basements

How dehumidifiers can help in basements and damp rooms

Meaco 10L Dehumidifier

Damp rooms in houses are unfortunately a very common occurrence and particularly in basements and basement flats.

It doesn’t matter what purpose you intend to use the room for; you should always keep it clean and maintain it properly.

When we talk about maintaining the basement of a house, the first thing which comes to mind is the humidity.

While small amounts of humidity is actually a good thing, the increased concentration of humidity can cause damage to paint and the walls of the basement and it can result in mould.

However, condensation can be significantly reduced if you identify the places where it’s likely to form and then eliminate its causes.




Combat Humidity:

Dehumidifiers are the first thing that you should use for combating condensation and humidity, and it is very handy when you have different rooms in the basement. Heightened humidity levels are eliminated by the dehumidifiers, saving a lot of money in repairs.

Here are some of the complications which are associated with humid rooms and basements, along with the ways in which a great humidifier may help in getting rid of them.

Damp and Muggy Basements:

Dampness can significantly damage the rooms in your home. In case any look or smell damp and wet, then you should immediately get a dehumidifier in order to eliminate condensation.

If you have set the basement as a family room, dampness can destroy the rugs and carpeting, and it can also smudge paint off the walls.

Higher humidity levels may even cause the wood to swell up and to weaken. It may also cause deterioration of the walls.

In case the situation is drastic, and the problem has begun to creep in to the walls of the basement, you will have to get a portable room dehumidifier. Such dehumidifiers are compact, portable and they can smoothly work without making too much noise. You can also purchase mini dehumidifiers with a 300ml capacity for smaller rooms. This rises from 10 to 20 and all the way up to 38 litre capacities depending on the size of the area.

The following are some of the common causes of dampness:

  • Heat from kitchen and unvented tumble dryers
  • Liquid from rainwater or groundwater.
  • Humid air which comes from the exterior of the house and in to the basement resulting in condensation

Mould Spores:

Mould spores are formed on walls and surfaces because of the severe moisture in the basement and other damp rooms.

Mould spores can be effectively dealt with, by maintaining the right humidity levels, which helps to reduce the growth of mould spores.

In case you notice that mould spores are developing on the walls or other surfaces, you should act fast. If you don’t, the spores will multiply, meaning that you will have to spend a lot of money in damages.

To combat this issue, you should get a dehumidifier as soon as possible. The mould spores damage the walls and the surface of the basement and more importantly, they are bad for your health.

Do you know that the severe development of mould in the house may result in symptoms like flu and severe cold? The only way of preventing mould from forming is to keep humidity levels in the house around 35% and definitely below 50%. This can only be achieved by a dehumidifier.

Bad Basement Odours:

It is often the case that dampness in a basement because of severe condensation results in a strong stench. Bad odours may also be caused by a lack of ventilation. In order to keep the things maintained and toned down, you should use a dehumidifier.

Dehumidifiers provide a great source of ventilation:

There are some dehumidifiers which are designed with HEPA and have carbon filters. They help a lot in getting rid of bad stenches and they keep the basement free of dust too.

In case the basement is used frequently for smoking, drinking or gaming, such dehumidifiers can be of great help.

How do the dehumidifiers work?

The dehumidifiers are designed in a way that they suck out the increased moisture levels in the air.

Most of the dehumidifiers have compressor fans; they suck in air as it passes over two refrigerant filled coil sets.

All the condensation and moisture the dehumidifier sucks in goes in to a tank of water. This tank has to be emptied once it reaches the limit.

Sizing capacity for the basement:

When you are selecting a dehumidifier for your basement, make sure that you get one which can take care of the humidity and condensation in your basement.

In case you have a large basement, you should buy a big dehumidifier because if you buy small one, it will not function effectively.

You may size the dehumidifier in terms of pints of moisture that you want to remove.

The level of moisture elimination that you want depends on the total size of your basement and its wetness. The ratings of 30, 40 and 50 refer to total pints of water which the dehumidifier is capable of removing in one day.

In case you want to have an accurate measure of the humidity in the basement, its best that you buy a thermo-hygrometer. It’s a contraption used for measuring the amount of humidity in the surrounding atmosphere.

One of the most important uses for thermo-hygrometers is monitoring the humidity levels in laboratories, industrial places and storage plants etc.

Dehumidifier Brands:

Some of the best brands out there currently producing dehumidifiers are:

These each manufacture a comprehensive range of dehumidifier models to suit any space, depending on your requirements.
