  3. Probreeze Renewable Cordless Mini Dehumidifier
  4. Gurin DHMD Renewable Wireless Dehumidifier

In this guide, I compiled a list of the best dehumidifiers for cars that are excellent at absorbing moisture from the air.

The Best Dehumidifier for Car

1. Patu Renewable Wireless Dehumidifier

A great portable dehumidifier for car

Patu adopts an eco-friendly approach with its power-efficient, wireless dehumidifier. It uses renewable silica gel technology, which you won’t have to replace for a full year of usage. Its compact design and quiet operation make it a natural fit in your car.

The silica gel’s color change indicates when it’s time to recharge your car dehumidifier. It comes with a built-in plug, eliminating the cluttering and inconvenience of cables. However, the dehumidifier’s heavy form factor might make it wobble and unstable when plugged into a wall outlet.

Moreover, you must find a secure spot in your car to place the dehumidifier, as it’s relatively fragile and can stop working if it takes a hard hit.


  • Eco-friendly
  • The moisture-absorbing bags last for a whole year
  • It only takes five hours for a full recharge


  • Fragile build

2. Eva Dry Mini Renewable Dehumidifier

One of the best moisture absorber for cars

We have yet another compact car dehumidifier, this time from Eva Dry. It uses silica gel beads as its moisture-absorbing material, lasting up to 30 days before needing to be recharged.

Though it’s more efficient with its power usage and lasts longer on a single charge, when compared to its Patu counterpart, Eva Dry’s Mini Dehumidifier can take double the time to charge its battery fully.

Such car dehumidifiers work for areas up to 333 cubic feet, meaning one is enough for a small car. Moreover, it comes with a holder to easily clip your sleek moisture-absorbing solution anywhere in the vehicle.

You’ll be happy with your purchase as the spill-free, odorless, and quiet operation ticks all the boxes for what makes an excellent dehumidifier for the car.


  • Portable, sleek form factor
  • It comes with a clip to easily hang it to your car’s mirror
  • Five-year warranty


  • One dehumidifier can’t absorb moisture efficiently from large-sized cars

3. Probreeze Renewable Cordless Mini Dehumidifier

One of the best car moisture absorber

Our third entry follows the same car dehumidifier formula set by Patu and Eva Dry but adds some tweaks that make it unique. Probreeze implemented a color wheel around the silica gel window, so you can easily compare the color gradient and know when your moisture-absorbing substance is saturated and needs recharging.

Probreeze’s Dehumidifier can take up to 24 hours to reach a full charge, which is by far longer than our first two entries. However, you need to keep an eye on the color indicator of the silica gel and unplug the dehumidifier once it’s charged, as it can get damaged if left in the wall outlet for extended periods.

When it comes to portability, Probreeze’s Dehumidifier shines with its sleek, ergonomic design that can stand on any side and fit in tight spaces. So, you can place it under the car seats or in the trunk to eliminate any dampness and prevent mold from growing in your car.


  • Stylish design with a dotted pattern
  • Intuitive indicator for the status of your moisture-absorbing bags


  • Can be damaged if overcharged

4. Gurin DHMD Renewable Wireless Dehumidifier


If you’re looking for a dehumidifier suitable for a large vehicle, Gurin DHMD is the way to go with its 500 cubic feet area rating. It’s relatively larger than other car dehumidifiers on our list, yet it covers larger spaces.

Gurin promises up to 10 years of usage before replacing your car dehumidifier, as the silica gel crystals are specially engineered to last longer. The future-proof design adds value to the consumer and, at the same time, ensures less waste is being produced, which makes it a more environmentally-friendly dehumidifier.

During my testing, I noticed that the dehumidifier has a relatively limited moisture-absorbing capacity. This means that it requires frequent charging, especially if you live in a humid climate.


  • Suitable for large vehicles
  • Future-proof
  • Five-year warranty


  • A relatively bulky form factor
  • Needs frequent charging

5. Eva Dry E-500 Renewable Mini Dehumidifier


Large car owners will be pleased with another dehumidifier suitable for more expansive spaces. Eva Dry E-500 secures its spot among the best car dehumidifiers thanks to its tight seal that never leaks moisture, even if it’s fully saturated.

The car dehumidifier does an excellent job of removing mold hiding in your car’s vent system and eliminating any musty odor that makes an unpleasant driving experience. It can absorb moisture efficiently for up to eight weeks before recharging.

When it comes to design, Eva Dry knocks it out of the park with its compact yet stable dehumidifier. It has a broad base that can sit steadily anywhere in your car, making it one of the most versatile car dehumidifiers on the market.


  • Leakage-free silica gel compartment
  • Sleek and stable form factor


  • Unreliable hanging clip

Are Car Dehumidifiers Any Good?

Yes, especially if you live in a humid area and don’t want mold to find its way into your car. Car dehumidifiers can be handy in the winter season as well. They absorb the water vapor you breathe, which can obscure your windshield and make driving more difficult.

The best car dehumidifiers can also help a lot with allergies. Dust mites and other allergens favor damp surfaces. So, by improving the air circulation in your car and getting rid of moisture, you maintain a healthy environment inside your vehicle.

Where Should I Place Car Dehumidifiers?

You can place your car dehumidifiers anywhere inside your car. Ideally, I’d choose the areas expected to have the most moisture for your car dehumidifiers to be as effective as possible. I suggest you consider some of the following places.


This is one of the most obvious spots to place your car dehumidifier. Being close to the windshield will ensure the condensed water vapor never obscures your view.

Center Console

Due to its proximity to your car’s air-conditioning and vent system, placing the car dehumidifier on the center console will significantly reduce mold growth in such hidden areas.

Car Trunk

Your gym shoes, grocery bags, and sports equipment have probably found their way into your car trunk one day or another. Placing a car dehumidifier will ensure none of their smells find their way into your car.

In Conclusion

On reviewing this list of the best car dehumidifiers, I’m sure that after using any of them, you won’t be able to remember how your life was before using a humidity-absorbing system.

The odorless, moisture-free, refreshing air circulation will make a pleasant driving experience while ensuring your car doesn’t suffer any mold-related damage.

For top-notch results, I suggest you go for Patu’s Renewable Wireless Dehumidifier. Its quiet operations, long lifespan, power efficiency, and overall eco-friendliness make it the go-to for the best dehumidifier for cars. It’s a mix of features that’s quite hard to strike.
