Dehumidifiers for Boats, Caravans and Cars

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.
