Types of car dehumidifiers

If you’re looking for ways to remove moisture and humidity from your car, then you will have a couple of options to choose from, which are as follows.

Electric car dehumidifiers

These dehumidifiers are powered by electricity and are designed to remove moisture from the air using a refrigeration or desiccant process. Electric dehumidifiers are often compact and can be plugged into your car’s power outlet (cigarette lighter socket) or a USB port.

Wireless or rechargeable car dehumidifiers

These dehumidifiers do not require a continuous power source. They typically use moisture-absorbing materials, such as silica gel or desiccant beads, to trap moisture from the air. Once the moisture-absorbing capacity is reached, you can recharge or rejuvenate the dehumidifier by plugging it into a power outlet.

Dessicant bags and pouches

These are moisture-absorbing bags or pouches filled with desiccant materials like silica gel. They are often hung or placed in different areas of the car, such as on the dashboard, under seats, or in the trunk. Dessicant bags are cost-effective and can help control moisture in small spaces.

Hanging car dehumidifiers

These are similar to dessicant bags but are specifically designed for cars. They usually come with a hook or string that allows you to hang them in various locations.

When choosing a car dehumidifier, consider factors such as the size of your car’s interior, your budget, the level of humidity in your area, and your personal preferences. It’s also important to read user reviews and product specifications to ensure that the dehumidifier meets your needs and expectations.

The benefits of using a car dehumidifier

Moisture Removal: Dehumidifiers are designed to remove excess moisture from the air. When you use a dehumidifier in your car, it helps to reduce the amount of moisture present in the cabin, making it less likely for condensation to form on the windows.

Balanced Interior Humidity: Maintaining a balanced humidity level inside the car can help prevent rapid temperature and humidity changes that lead to fogging. A dehumidifier helps stabilize the humidity, reducing the likelihood of foggy windows.

Improved Visibility: With reduced fogging, your visibility improves, making driving safer and more comfortable.

Preventing Musty Odors: Excess moisture will eventually lead to the growth of mold and mildew, which can cause musty odors. Using a car dehumidifier helps prevent these odors by reducing the moisture that fosters their growth.

Here we have reviewed the Eva Dry Wireless, the Afloia Cordless, the Ivation IVADM10, and the Barska Moisture Absorber.

Eva Dry wireless mini-dehumidifier

Trusted brand, Eva-Dry, brings you this small, yet powerful, and easy to use mini-dehumidifier. The best part is that its low maintenance, doesn’t spill or mess, and it doesn’t require any cords or batteries.

The device, which is perfectly safe for pets and kids, is 9 x 8.25 x 2.88 inches in size, yet powerful enough to remove moisture and humidity in spaces of over 300 cubic feet – which makes it ideal for small spaces such as car interiors.

Afloia cordless rechargeable dehumidifier

If you are looking for a highly efficient and convenient dehumidifier for small spaces – such as your car, then the Afloia Cordless Rechargeable Dehumidifier is a great option to consider. It has the ability to remove up to 6 ounces/170ml of water per day, and is perfect for areas up to 55 square feet.

One of the most impressive features of this dehumidifier is its renewable technology, because it can be recharged in just 2 hours and can be reused up to 300+ times. This means that you save money and reduce waste by using a product that is both efficient and eco-friendly.

Also, the 360° circular air inlet design ensures that every silica bead fully absorbs moisture, even in isolated spaces with poor airflow.

As mentioned, the device is cordless and can be used alone without charging, making it ideal for use in small spaces such as bookcases, electronic storage cabinets, cars, closets, boats, cabinets, gun safes, and even bags. It’s non-toxic, odorless, and non-corrosive, making it safe for use around children and pets.

Ivation IVADM10 small thermo-electric dehumidifier

The Ivation IVADM10 thermo-electric dehumidifier is a remarkable product because of its many impressive features. First, the dehumidifier uses thermo-electric peltier module technology, which means it has no moving parts – so it operates quietly and has a longer lifespan. This allows the unit to be small and compact, measuring at just 6.1 x 5.1 x 8.7 inches, yet still packs a powerful punch.

It’s perfect for small spaces and can reduce humidity in closets, basements, crawl spaces, RVs, boats, cars, bathrooms, bedrooms, and other small areas. It has a removable 17-ounce water tank and has a ‘tank full’ indicator light that automatically shuts off the unit once the water reservoir is full. This means that you don’t have to monitor the unit constantly.

It’s also easy to use. All you have to do is make sure the removable water-collection reservoir is securely in place and put it in any area that requires de-humidification.

Barska safe moisture absorber

The BARSKA safe moisture absorber is an excellent product for those looking to protect their sensitive valuables from moisture damage. It is a small, reusable dehumidifier designed for use in any small, closed place such as home closets, safes, cars, RVs, boats, and other storage containers. The bag is filled with moisture-absorbing silicon dioxide, making it safe to use and microwave-safe.

It has a humidity indicator, which turns from blue to pink when it reaches its absorption capacity. This is especially helpful in making sure that the dehumidifier is functioning properly and when it’s time to renew it. You renew it by microwaving it for up to 4 minutes at 600W, which makes it cost-effective over the long-term.

So, how effective is it? The bag can absorb up to 45 grams of moisture, which is enough to bring humidity down from 90% to below 50% in a space of 3 cubic meters. This is remarkable considering its size.

Where is the best place to put a dehumidifier in a car?

Placing a dehumidifier in the right location within your car is essential to effectively reduce moisture levels and maintain a dry interior. Here are some optimal places to consider when positioning a dehumidifier in your car:

Front passenger seat or dashboard

This is one of the most common and convenient locations to place a dehumidifier. You can secure the dehumidifier on the dashboard or the front passenger seat using a non-slip mat or a mounting accessory designed for cars. Ensure that the dehumidifier’s air intake and exhaust vents are not obstructed, allowing it to circulate air effectively throughout the cabin.

Back seat or rear floor area

Placing the dehumidifier on the back seat or rear floor area can also be effective, especially if your car has a larger cabin. Make sure it’s positioned securely and not prone to tipping over during sudden stops or turns.

Center console or cup holder

For smaller car dehumidifiers, the center console or cup holder area can be suitable places. This location keeps the dehumidifier discreet while still allowing it to absorb moisture from the air. Ensure that it doesn’t interfere with your driving or access to controls.

Trunk or cargo area

If your car has a significant moisture issue or you’re looking to dehumidify the entire cabin, you can place a larger dehumidifier in the trunk or cargo area. Keep in mind that this might be less convenient if you need to access the dehumidifier frequently.

Under the front seats

Some car dehumidifiers are designed to fit under the front seats of your car. This can be a good option if you prefer a more hidden placement. Make sure there is enough space and proper ventilation to allow the dehumidifier to work effectively.

Attach to seat backs

For smaller dehumidifiers, you can attach them to the back of the front seats using adjustable straps or hooks. This keeps the dehumidifier out of the way while allowing it to absorb moisture from the air circulating in the cabin.

Remember these important tips when placing a dehumidifier in your car:

Ensure Proper Ventilation: Whichever location you choose, ensure that the dehumidifier has adequate space around it for proper airflow. This allows it to effectively draw in humid air and release dry air.

Secure Placement: Make sure the car dehumidifier is securely positioned to prevent tipping or shifting during driving.

Access: Consider how easy it will be to access the dehumidifier for emptying the water reservoir or recharging (for wireless models).

Safety: Ensure that the car dehumidifier’s placement doesn’t interfere with your driving or create any safety hazards.

Will a dehumidifier stop my car fogging up?

Yes, a dehumidifier can help reduce or prevent your car from fogging up. Fogging of car windows occurs when moisture in the air comes into contact with a colder surface, causing condensation to form. This can happen during cold weather, rain, or when there is a significant difference in temperature and humidity between the inside and outside of the car.

By using a dehumidifier in your car, you can effectively reduce the moisture levels in the air, which in turn helps minimize the occurrence of fogging on your windows.

Does putting a dehumidifier in your car if it’s wet prevent smells?

Yes, using a dehumidifier in your car can help prevent or reduce unpleasant smells caused by excess moisture. Moisture in the car’s interior can create an environment conducive to the growth of mold, mildew, and bacteria, which are common sources of musty and unpleasant odors. So, by using a car dehumidifier, you can effectively remove excess moisture from the air, which in turn helps to inhibit the growth of these odor-causing agents.

Here’s how a car dehumidifier can help prevent smells:

Mold and Mildew Prevention: Excess moisture provides an ideal environment for mold and mildew to thrive. By removing moisture from the air, a dehumidifier helps to inhibit the growth of these fungi, which are major contributors to musty odors.

Bacterial Growth Reduction: Bacteria can also flourish in damp environments. By maintaining lower humidity levels with a dehumidifier, you create conditions that are less favorable for bacterial growth, thereby reducing potential odor sources.

Odor Absorption: Some dehumidifiers are equipped with additional features or materials designed to absorb and neutralize odors. These types of dehumidifiers can actively help to reduce existing smells in your car.

Drying Out Wet Items: If your car’s interior has become wet due to spills or water ingress, a dehumidifier can help accelerate the drying process, reducing the likelihood of odors developing.

While a dehumidifier can be effective in preventing and reducing odors caused by excess moisture, it’s important to note that it may not completely eliminate all odors. If there are persistent or strong odors in your car, it’s a good idea to address the root causes, such as cleaning and disinfecting surfaces, vacuuming, and addressing any underlying issues that may be contributing to the smell.


Maintaining a dry and fresh interior is crucial for the overall comfort and longevity of your vehicle. The best car dehumidifiers mentioned above offer a range of options to suit different needs and vehicle sizes. From compact wireless models to larger capacity units with advanced features, these dehumidifiers can help you combat moisture, prevent odors, and protect your car’s interior. Choose the one that best fits your requirements and enjoy a more enjoyable and pleasant driving experience.
