Find the best car dehumidifier with our comprehensive review. Minimise condensation on your windows and travel safely every time.
When you get in your car in the morning, are you regularly met with condensation all over the windows?
If this is a common occurrence, then this can quickly get annoying as you'll need to waste time removing all the mist before you can set off on your journey. Over time this can get worse and lead to streams of water flowing down the insides of your window, which isn't nice, especially if it ends up on the driver seat making your journey less enjoyable.
Fortunately as annoying as condensation is, it's fairly easy to treat and remove. Car dehumidifiers work to remove the excess moisture from the air to decrease the humidity to match the levels outside of your vehicle, which stops condensation from forming.
There are several types of options to choose from which can make the buying decision harder, but we've reviewed the best car dehumidifiers and the best car moisture absorbers on the market.
This massive choice means that there is a product to suit everyone's needs, so stay tuned and read below to find your solution. These types include 12 Volt dehumidifiers and reusable moisture absorbers and homemade DIY dehumidifiers.

What Causes Condensation?
When you get in the car in the morning, you'll often notice that although the heating isn't on, it's still slightly warmer than the temperature outside of the car. However, this is the main reason that condensation and misting forms to begin with.
Condensation and misting occur when there's a difference in temperature between the inside and outside of the vehicle. If the inside of your car is more humid than outside, this causes a strong imbalance in moisture and temperature gradient.
This is easily done in the cold winter months in Britain, especially because car doors are sealed tightly when shut, so the moisture and temperature gradient is maintained.
If the temperature outside is lower than inside your car then as the air moves towards your car, they convert to droplets. So the greater the humidity, the worse the issue is, and the more droplets are produced until you can't see through the windows or windscreen.
Types of Car Moisture Absorber
If you're looking for the best solution, then there are only three main types of car dehumidifier that will work effectively. These are the moisture-absorbing and 12-volt models with the third being a combination of two which are battery-powered dehumidifiers.
Moisture Absorbing Dehumidifier
Moisture absorbers are the most affordable option and are popular for car owners because they can be used 24/7 and don't need a power source which means you can use them even when the engines off or when you're driving.
Once you've opened it, they will start to absorb excess moisture until they're full and need the moisture to be removed.
These absorbers work independently, and the best options will usually have an indicator on the packaging that notifies you when it's full. Then you simply can put on a radiator or in the microwave to remove the moisture and then you can re-use it.
They're low priced, and because they're reusable they can often last many years of consistent use, so you definitely get your money's worth.
12 Volt Dehumidifier
As you'd expect, these are more effective and remove moisture faster than non-electric models, but they need the power to operate. They have small water tanks where moisture collects, which means they have larger capacities although these tanks need to be emptied when full.
It's advised not to drive with the unit on, but this will depend on the severity of your condensation. Also, if the tank is too full, it can topple over if you take a sharp turn or brake suddenly.
The price you can expect to pay is more than a moisture absorber, but this is due to the faster dehumidifying process and capacity. This type is ideal if you have strong damp symptoms in your car and need extensive treatment that an absorber may not be able to deliver.
Due to needing a 12V power source, this means that it can be plugged into a cigarette lighter.
Battery Powered Dehumidifier
This type also has a water tank that needs to be emptied once it's full of excess moisture, but instead of relying on a cigarette lighter for the power, it can run off batteries. This means that you don't need to depend on keeping your car engine constantly running.
Car Dehumidifier Buying Guide
Luckily most car moisture absorbers are reusable, which means that they will last a considerable length of time. With 12V models when the water tank is full, all you need to do is empty it down the drain or toilet and then connect it back to the power source in your car and switch it back on.
If you have a moisture absorber, then you either need to put it in the microwave or place it onto a radiator. Single-use models aren't ideal because it'll cost you more money and it isn't great for the environment.
It may be tempting to get a single-use model but is only recommended if condensation isn't a long term problem and you just need a temporary solution.
The shape design of the model is also important. If you have a 12V or battery-powered car dehumidifier then ideally it should have a square or stable base which means that it can be used while you drive without it falling over.
Just like any product that you buy, you need to pick a dependable brand because the top brands will create more reliable products that will last longer. Well established brands will often have products that have been in the market for longer, so have accumulated a greater volume of reviews so you can make a more accurate buying decision.
The price is closely linked with the brand that you decide to buy, and we all know that price is an important factor for most buyers regardless of the type of product we're buying. Higher quality brands will often be slightly more expensive, but this will usually be because they use higher quality materials that will last longer and have stronger dehumidifying effects on your car.
If your product lasts longer, then you'll save money in the long run as you'll need to replace it less often.
Buying a car dehumidifier won't solve the problem if you don't stop the cause and there are several steps you can take.
Maintain Good Air Circulation
If you have a newer car, then you'll be able to make use of the defrost button which should be your first port of call if your vehicle is suffering from condensation. Air conditioning works well to combat condensation because it removes moisture from the air. Using these functions regularly.
However, we understand that not all cars have a defrost setting or air conditioning, so at the bare minimum, you should air the vehicle, which will help to reduce the causes of condensation. When you use the heating or air-conditioning, you should direct the airflow towards the sources of damp in your vehicle which will help to dry them out quicker.
Check for Leaks
Damp and condensation is often caused by leaks that are a result of worn-down seals or vents in your vehicle.
This is common in areas that we rarely check such as the boot of the car. You can either visually check or manually run your hand along with the seals for any signs of damage. If there is any damage then all you need to do it fix the source of the leak.
The windows and door seals are also a common cause of leaks, especially in the winter season where rain can splash on to your car door and leak into your vehicle.
Several solutions are simple to implement:
- In dry weather drive with your windows open as this will draw air In to circulate your vehicle and lower the level of moisture in your car.
- When the weather is dry, leave your windows slightly open as this will provide an escape for the humid air and reduce the effects of condensation. You should avoid leaving them open overnight, though from a security point of view.
- Close your windows when it rains; otherwise, this is another source for water droplets and damp to form in your vehicle.
- Regularly cleaning the windscreen will reduce the level of condensation because water droplets bond to dirt and grime particles.
- Don't keep any sweaty clothes such as your gym kit in your car for days on end as the clothes or towel can cause damp to form.
- Any drink spillages or wet seats should be dealt with immediately to get rid of any moisture in your vehicle.
- If you have access to a garage, then make use of it. This will lower the gradient between your car and your garage, which will reduce the level of condensation. Also, because it'll be locked in a garage, you can leave the windows open for greater results.
