How Do You Decide if You Need a Car Dehumidifier?

Many people who come across car dehumidifiers do not even know if they need a dehumidifier for their car or not. If you are also confused about whether you should get a car dehumidifier or not, then don’t worry.

Here is a step-by-step process to determine if your car needs a dehumidifier.

  1. Check the average climate in your region

Depending on where you live, the humidity will be higher or lower. For example, people who live in coastal areas, e.g., near a beach, are more likely to face high humidity. Not only can this high humidity make you feel warm, but it is also one of the reasons why the metal in your home or car corrodes!

So, if your region, city, or area usually has high humidity, you probably need a car dehumidifier.

But, how much humidity is too much humidity?

According to experts, anywhere from 45-50% humidity is perfect for human body. This level of humidity also does not have any side effects on metal. The humidity of more than 50% can cause mold and mildew growth in your car. And humidity lower than that can make the environment drier and cause health-related issues.

  1. Check the humidity of your car

Now, if you checked the humidity in your region and it is higher than 50%, your car will also have high humidity. But how can you be sure?

SensorPush HT1
SensorPush HT1

Well, a simple way to check the humidity level in your car is by using the hygrometer. This device helps determine the humidity level in cars, homes, offices, and other areas. You can use a device like SensorPush HT1. This product is a smart hygrometer and lets you check the humidity with one touch. 

All you have to do is get the device and place it in your car. And check the hygrometer in a few minutes. You need to get a car dehumidifier if the device gives you a number higher than 50% or 50%.

However, if the hygrometer shows a lower than 30%, you should get a car humidifier instead.

My Experience With Dehumidifiers For Cars

Before we go ahead with the tips and tricks and the best car dehumidifier recommendations, let’s get one thing out. There are thousands, if not millions, of people on the internet who have their 2 cents to give about everything.

Well, here is my personal experience, which made me write this car dehumidifier blog:

I have two collector cars in my garage, which I adore. However, I did not know how high the humidity in my garage was until the motors in my collector car started corroding.

And because of the corrosion, the motors had trouble starting. I called a mechanic and then got to know that the main issue was the high humidity.

After that, I did my research and found the best car and garage dehumidifier. I installed disposable car dehumidifiers in each of my cars. And installed a dehumidifier in my garage.

The garage dehumidifier tank fills up every 5-6 days and is easy to empty. On the other hand, the disposable dehumidifier in each of my cars is just a fail-safe.

It has not been filled yet. But if my garage dehumidifier stops working, the disposable dehumidifier will keep the interior of the collector cars safe.

Top 10 Best Car Dehumidifiers

Now that you know why you can trust me, here are top 10 car dehumidifiers I came across. All of the dehumidifiers on this list are tried, tested, and loved by the customers.

But only get the dehumidifier that best suits your needs to ensure the best experience.

So, let’s get started!

Best Dehumidifier for Car: Afloia mini wireless dehumidifier

The Afloia car dehumidifier is called the best for a reason. It is packed with features that are a must in car dehumidifiers. This dehumidifier can remove up to 100 ml of moisture with a single charge. Moreover, it is perfect for a 54 sq. area which makes it ideal for cars, vans, and RVs.

First, this dehumidifier is small. And hence, it is easier to fit in tiny spaces. No matter how small your RV or car is, I am sure you will find a spot to place the Afloia mini dehumidifier.

Secondly, the Afloia dehumidifier is renewable. This car dehumidifier is filled with orange silica beads to soak up the excess moisture from the air. And when the beads change their color to green, they can no longer reduce the humidity.

So, what do you do then?

Well, just plug in the dehumidifier and let the magic happen. The bead will turn from green to orange again, which means you can reuse it.

If you are someone who easily forgets everything, then the auto-off feature will be your savior. This feature is exactly what it sounds like. 

The dehumidifier stops charging after two hours. So, even if it’s still connected to the electricity, the dehumidifier base will cool down and stop the charging process.

This simple feature can prevent many fire hazards.

But, if the beads are still not turned orange after 2 hours, you can unplug and then replug the dehumidifier. This will start the renewing process.

If you thought this dehumidifier had nothing more to happen, then you were wrong!

This Afloia LED screen will surprise you. It tells you the humidity level, and you can also check the current temperature in both Celcius and Fahrenheit.

Moreover, you can check the humidity records with just a touch.

Every RV and car is different. Then why should every car dehumidifier be the same? The Afloia mini dehumidifier offers 3 mounting options.

  1. The standard table stand.
  2. Magnetic mounting.
  3. Hanging hole mounting.


  • Compact and travel-friendly
  • Versatile humidity monitor
  • 3 different mounting options
  • Auto-off charging
  • Renewable
  • 360 degrees air inlet
  • Cordless design

Best Halfords Car Dehumidifier: Afloia Safe wireless dehumidifier

Safety should be your priority when using a dehumidifier in such a closed space. The dehumidifier can even cause a fire hazard if it is not well-made. And this mini dehumidifier by Afloia is made while keeping safety in mind.

The Afloia mini dehumidifier can absorb up to 4 ounces of moisture on one charge. And it is perfect for small spaces like cars, RVs, closets, and bathrooms.

One of the things that I love about this dehumidifier is that it is renewable. You can use it to reduce the moisture and humidity level in your car over and over again.

This dehumidifier is filled with moisture-absorbing beads, which change color when the beads are filled. Then you can charge it, and within 2 hours, the dehumidifier will be ready to work again!

Using a corded dehumidifier while young kids or pets are in the car can be dangerous. If the kid is not careful, they can trip on the cord. Or an untrained pet can even chew on the cord and cause a hazard.

But with the Afloia dehumidifier , that will never be a problem. This dehumidifier is cordless and does not need a direct electrical connection to work.

Traveling in a small vehicle means you cannot let even the tiniest space go to waste. In situations like this, using a full-size dehumidifier can cause problems. But the Afloia dehumidifier will never do that.

This dehumidifier is portable enough to fit in any small car. You can place it on the car’s floor, and the dehumidifier will work perfectly.

The circular air inlet allows the dehumidifier to intake the air from every direction and work faster than conventional dehumidifiers. The 360 air inlet also means that you do not have to place the dehumidifier in a certain way for it to work properly. You can place it wherever you find the space, and the dehumidifier will work to its full capacity.

If you are more interested in an electrical dehumidifier for your car, check out the Eva-Dry EDV-1100 dehumidifier. As the name suggests, this Eva-Dry dehumidifier is perfect for an 1100 sq. ft. area.

One of the main reasons people do not like electrical dehumidifiers is because most of these products are noisy. However, that is not true about the Eva-Dry dehumidifier.

This dehumidifier only makes a 50 dB noise. This noise is so low that you will not be able to listen to it. This quiet operation makes it perfect for small spaces where you can hear everything.

Another reason you might not like the idea of electric dehumidifiers is that most of them consume a lot of energy. But fortunately, you do not have to worry about your energy cost while using Eva-Dry.

This dehumidifier uses less energy than most other electric dehumidifiers on the market. And this makes it perfect for people who are on a tight budget.

Cars and RVs are always on the move. And this means a dehumidifier that collects water will spill it everywhere, right?

If you have multiple devices in your RV, then it must be difficult to keep an eye on all of them at the same time. You do not have to worry about constantly checking the Eva-Dry dehumidifier.

You can put this dehumidifier in your camp and still won’t listen to anything.

As the COYCYQI is an electrical dehumidifier, you might be worried about the energy bill. Well, you should not!

This dehumidifier runs at only 36 watts per hour. You can run it almost daily and will not see a huge difference in your monthly energy cost.

Living in a high humidity area means the dehumidifier would be working extra hours. And sometimes, the tank fills up quicker than you had anticipated.

But that will never be a problem with the COYCYQI dehumidifier. This dehumidifier has a 17 ounces water tank. So, you can let your dehumidifier run without worrying about it filling too quickly.

Moreover, as the water tank is transparent, you can easily see when it fills up. And hence you will be able to empty it before it spills.

It can remove up to 18 ounces of moisture from the air every day! And as this dehumidifier is suitable for a 250 sq. ft. area, it will be perfect for your car or RV.

As this dehumidifier offers a large water tank, it is easier to forget about emptying it every few days. But don’t worry. Even if you forget to empty the dehumidifier on time, the water will not spill.

The energy bill always seems to be a huge factor when buying an electric dehumidifier. Because if the dehumidifier is not cost-effective, it can raise the energy bill drastically.

But, as said before, the DJDK dehumidifier is smaller and has a smaller motor. This means that this dehumidifier uses less energy and keeps the energy bill and humidity low.

Fortunately, the DJDK dehumidifier features a medium-size water tank. But along with that, the dehumidifier also features auto shut-off features.

The dehumidifier’s indicator light starts blinking when the water tank fills to the brim. But if you cannot empty the water tank, the dehumidifier will stop working.

Best Dehumidifier for Car Interior: Afloia dehumidifier without any leaks

Are you a car collector and would like to have your collector car’s interior from humidity? Well, then you should check out this Afloia dehumidifier. 

This dehumidifier is ultra-small and 100% spill-proof. This means you would never have to worry about the water tank spilling in your car again.

One of the best things about the Afloia dehumidifier is renewable. This dehumidifier is filled with moisture-absorbing beads. The beads are orange in color but change to green when they are filled with moisture.

Once the beads are green, plug in the dehumidifier, and within 2 hours, your dehumidifier will be ready to work again!

Most car collectors do not like to turn on their collector cars that much. Moreover, if the car model is old, it might not have a 12V or a USB port. This makes electric dehumidifiers a big no-no.

The Afloia dehumidifier cordless design makes it easy to use in a collector car.

The Afloia dehumidifier can remove up to 100 ml of moisture from the air every day. As collector cars are usually not opened that often, the humidity level in these cars is not that high. So, hopefully, you will not need to recharge the dehumidifier that often.

The Afloia dehumidifier features a 360-degree air inlet. It means no matter where you put this dehumidifier in your car. The dehumidifier will absorb the moisture from every corner.

Yes, I said that this dehumidifier is perfect for collector cars. But that does not mean you cannot use it in any other RV. If you have a small-size RV, then this dehumidifier would be perfect for that.

The Zarpax car dehumidifier is renewable. Once the indicator changes its color from blue to pink, it is time to charge this dehumidifier. And then you can use it again.

Putting a dehumidifier on the car dashboard meant that the device would move significantly. And if the dehumidifier is not well made, it can lead to leakage.

The following are some of the key features of a Moisture absorber dehumidifier:

Electric dehumidifiers are good, but not all-electric dehumidifiers are built the same. If you do not research and buy a random electric dehumidifier, it can affect your energy bill. Moreover, using electric dehumidifiers with toddlers is not safe. So, what’s the solution?

Just use a dehumidifier that works without electricity or a battery!

The moisture absorbers work completely without any electricity or battery. And this makes them the safest dehumidifier to use around kids.

It will not dry out the air if you forget to set a dehumidifier correctly. Just as high humidity is not good for you, humidity lower than 30% can also cause some serious issues. Moreover, it is not good for plants either.

Why Do You Need A Car Dehumidifier?

If you have made it this far in the car dehumidifier article, you are either in dire need of a car dehumidifier or just love reading about it. But do you even know why using a car dehumidifier is a great idea?

Here are some of the reasons why your car needs a dehumidifier!

  1. Safe driving

As absurd as it sounds, having a car dehumidifier can make the driving experience much safer. And here is how!

High humidity in your car means that you would see condensation on your car windows and windshield. In other words, there would be moisture on the car windows and windshield. And this condensation process can make the glasses blurry and block your vision of the road.

As a car dehumidifier reduces the humidity, you will not have to worry about a foggy windshield again. And hence, you will be able to drive much safer than ever.

  1. Prevents mold and mildew

Whether it is your house or car, no one likes to see mold growing in their space. This mold and mildew look disgusting and have dangerous effects on your body. Being surrounded by mold and mildew daily can affect your lungs and breathing.

On top of that, if you are already sensitive and have lung-related diseases, mold and mildew in your car can worsen your symptoms. So, what to do?

Mould is prone to grow in higher humidity areas. For example, if your car has humidity higher than 50%, the mold and mildew have already started growing.

But installing a small car dehumidifier can reduce the humidity immediately. And the reduced humidity prevents the growth of mold and mildew in your car.

  1. Keep electronics safe

Wait, how can a car dehumidifier keep your electronics safe?

Well, as you know, spraying water on your electronics is never a good idea, right? High humidity is almost the same concept. 

High humidity in your car means that the electronics in your car are constantly surrounded by moisture. And if the humidity stays high for a long period, the electronics can malfunction and even stop working altogether.

The moisture can even travel in the device and cause a short circuit. The short circuit can then lead to a fire hazard in your car.

Installing a car dehumidifier maintains the humidity of the car. And by doing this small task, the car dehumidifier keeps the electronics in your car safe and working to their full capacity.

  1. Prevents the wood from rotting

Wood is one of the many materials prone to rotting in high humidity. And if your car has wood installment, then high humidity can be detrimental to your car.

Many people love to have wooden dashboards and panels in their RVs and vans. But if you live in a high humidity area, say goodbye to the wooden aesthetic because the high humidity will cause the wood to rot within a few weeks.

Or, just install a car dehumidifier!

The dehumidifier will lower the humidity and cause the perfect environment for your wood furniture and decor.

  1. Prevents corrosion

Metal corrodes! And it would be great to live in a world where you did not have to worry about any rust and corrosion, but that is not possible. However, installing a car dehumidifier is 100% doable.

You see, metal is a highly reactive element. And there is moisture in the air; the moisture reacts with the metal and causes it to oxide or corrode.

As a dehumidifier removes the excess moisture from the air, the metal will not react. And hence, the metal installments in your car will stay shining and brand new.

Key Factors to Consider Car Dehumidifiers

At first, glance, buying a car dehumidifier seems like an easy and mundane task. You buy the first one that catches your eyes, and that’s it. Right?


You should consider several factors before adding a car dehumidifier to your cart. So, if you want to ensure that you get the best dehumidifier for your car, keep reading.

  1. Dehumidifier type

Dehumidifiers come in different types. And these different types of dehumidifiers have different pros and cons. For example, a cordless dehumidifier would be perfect for your car because most cars do not have an AC power system.

For this same reason, a dehumidifier bag is also considered great for use in a car. These dehumidifiers are small, ways to fit in a small vehicle, and do not need electricity to run.

  1. Operation range

If you have been researching car dehumidifiers for a while, you must have come across product listings that say “suitable for the area.” This phrase means that a certain dehumidifier can successfully dehumidify in x amount of space.

For example, some dehumidifiers are suitable for 100 sq. ft. Meanwhile, others can dehumidify an area as big as 2000 sq. ft. But as cars are usually pretty small, you do not need to buy a 2000 sq. ft. dehumidifier.

A dehumidifier suitable for 100 sq. ft. or less would work perfectly for a regular-sized car.

  1. Dehumidification efficiency

Another factor to consider while buying a car dehumidifier is the dehumidification efficiency. When it comes to dehumidification efficiency, electric dehumidifiers are the best. But that does not mean you can buy an electric dehumidifier for your car.

As cars are usually small, small dehumidifiers can work amazingly and reduce dehumidification. A dehumidifier with 1 ounce or above dehumidification efficiency would work great for a car. However, if your car is bigger than average and you live in an extremely humid area, you might need a dehumidifier with high dehumidification efficiency. 

  1. Dimensions

One of the most important factors to consider when buying a dehumidifier for your car is the product’s dimensions.

Many dehumidifiers are marketed as car dehumidifiers but are bigger and bulkier. Due to their bigger size, the dehumidifier is unsuitable for average cars.

So, when deciding to buy a dehumidifier, check its dimensions. Only buy it if it is small enough to fit in your car.

  1. Noise level

If you are easily irritated by loud noises, you should check out the noise level of the car dehumidifier before buying it. Most car dehumidifiers are usually quiet. This allows the customer to enjoy fresh air without listening to awful noise.

Dehumidifiers with 45 dB or lower are considered super quiet. Meanwhile, the 50db dehumidifier makes a little noise, but they are still tolerable.

  1. Electric dehumidifier vs. dehumidifier bag

Like any other product variants, both electric dehumidifiers and dehumidifier bags come with their pros and cons.

For example, if you get an electric dehumidifier, then it won’t be able to work if the car is turned off. But on the other hand, a dehumidifier bag will work perfectly fine without electricity.

  1. Rechargeable vs. disposable dehumidifiers

The last factor to consider when buying a car’s dehumidifier is whether you want a rechargeable or disposable dehumidifier. As the name suggests, a rechargeable dehumidifier can be recharged and used repeatedly.

Meanwhile, a disposable dehumidifier stops collecting moisture after a certain time. And then, you can replace it with a new dehumidifier.

In my opinion, rechargeable dehumidifiers are the best type of dehumidifiers. Not only are they cost-effective, but they are also eco-friendly.

But, it is always good to get a disposable dehumidifier in your car for emergencies. For example, if you forget to recharge your regular dehumidifier, just whip out the disposable dehumidifier and use it for a single drive.

Where Do I Put the Dehumidifier in The Car?

Usually, you can put the car dehumidifier anywhere in your car. But some spots are perfect for placing the car dehumidifiers. So, let’s find out where to put the car dehumidifier for maximum effect!

Car Dashboard

Does your car windshield suffer from condensation, and you cannot see clearly when driving? If your answer to both of these questions is yes, then you should put the car dehumidifier on your dashboard.

By putting a car dehumidifier on the dashboard, the dehumidifier can easily reduce the humidity near the windshield. And by reducing the humidity, the condensation will also go down. This will lead to a clear windshield and a safe driving experience.

In my opinion, desiccant dehumidifiers are the perfect dehumidifiers to put on the car dashboard.

Centre console

The Centre console is the perfect place to put your car dehumidifier. The humidity in your entire car is high. By putting the dehumidifier on the center console, the humidifier can easily intake from the surroundings and reduce the humidity.

The best car dehumidifier for the center console would be a cordless dehumidifier with 360 degrees air inlet.

Car trunk

Storing damp clothes in the car trunk after a beach picnic is a great way to keep your car dry. But your car might end up smelling like dead fish. To prevent this from happening, put the dehumidifier in the car trunk.

You can use any type of car dehumidifier to put in the car. But Remember that the dehumidifier might trip and spill the water if you take a wrong turn. So, choose a dehumidifier that is spill- and leak-proof.

Rear Windshield Shelf

Last but not least, the rear windshield shelf is also a great place to put your car dehumidifier. If the humidity in your car is not extremely high, but you want to maintain it, then this is the perfect spot. A disposable dehumidifier would be the right choice for a rear windshield shelf.

Other Ways to Reduce Humidity for Your Car?

Car dehumidifiers are a godsend and can make your car feel fresh. But using a car dehumidifier is not your only option.

There are many ways to reduce the humidity level in your car. And following are some of the tips to do exactly that!

  1. Proper ventilation

Proper ventilation will be your best friend if you want to avoid excess moisture accumulation in your car, van, or RV. Just by opening the windows and letting the air circulate through your vehicle, you can get rid of a good percentage of the humidity.

However, this tip will not be effective if the humidity outside your vehicle is the same or higher than the humidity inside your vehicle.

  1. Reduced cooking time

Nothing feels better than cooking in your RV and eating a homemade meal. But excess cooking in the RV can also be a reason for high humidity in your vehicle.

The best way to eliminate this issue is by reducing the cooking time in your RV. You can set up the stove outside of the RV and cook in the open air. This way, the humidity will not build up in your RV.

However, if you cannot cook outside for some reason, just open up the windows and door of your RV while cooking. The active air circulation will prevent the humidity from rising.

  1. Control the temperature

The sudden and constant change in the temperature in your RV and car can also be a reason behind the high humidity. So, if you are dramatically changing your vehicle’s heating and cooling settings throughout the day, stop it!

The cooling and heating should be carried out slowly. This will prevent the humidity from rising and will also stop condensation.

  1. Use moisture-proof products

Another great way to prevent the humidity from rising in your RV and car is by using moisture-proof products. Products with activated carbon are amazing for absorbing moisture and reducing the humidity level.

However, you should be cautious when using such products. Because most of the time, you cannot manually control the humidity level. And if used incorrectly, the humidity level can quickly drop to an unhealthy level.

  1. Turn on the AC

Yes, air conditioners make the atmosphere cooler but do you know this process is done? Conventional air conditioners remove excess moisture from the air and pump out cooler air. This means you can turn on your RV air conditioner, and the humidity level will go down.

But, keep in mind that an AC cannot replace a dehumidifier. So, if the humidity level in your RV is extremely high, then use both AC and a proper car dehumidifier to adjust the humidity level.

  1. Close the windows

Yes, in this exact list, I told you to open the windows for good ventilation. But sometimes, closing the windows is better to control the humidity level in your car. How?

Let me explain!

If the humidity level outside your car is high or it is raining, opening the windows can raise the humidity in your car. So, it is best to close the windows and lock out the humidity outside in both situations.

  1. Remove all wet objects

Wet objects such as wet towels, clothes, and shoes can also cause the humidity to rise. Removing these objects from the car is the best way to prevent this. Let them dry outside before bringing them in.

  1. Remove food waste

This might come as a surprise, but yes, accumulative food waste can also cause the humidity to rise. The best way to prevent it is by simply removing the food waste from your car But it is best to build the habit of removing the food waste every night or every morning to keep the environment in your car as clean as possible.

  1. Check for leaks

Clogged car vents are notorious for raising the humidity in an RV and car. So, regularly check the vehicles for leakage.

If you have interior piping for water in your car, then it is best to monthly or weekly check those for leakage as well. Because if these leakages go unnoticed, they can cause drastic damage to the interior of your car.

  1. Drying Out Your Car With a Blower

Another unusual tip that works is drying out your car with a blower. If you traveled from a high humidity area, drying out your car’s interior with a blower would drastically lower the RV humidity and keep the air fresh.
