This unit is 100% renewable, meaning that the silica gel technology used will never run out or need to be replaced. Additionally, this unit also lasts 20-30 days before needing to be recharged, making it a very low-maintenance option. Plus, it shows when it’s time to charge the item by changing the color and it will take around 10 hours to fully charge.

The Pro Breeze Wireless Mini Dehumidifier shares similar design and functionality traits with the editor’s choice. For instance, it covers the same 333 cubic feet of space as the Eva-dry E-333. Another similarity is the indicator light turns orange when working and green when it’s at capacity. You also get between 20 and 30 days before having to renew or recharge both models. However, one difference is its five-ounce capacity, while the E-333 can hold up to six ounces. This can be attributed to its smaller dimensions.

  • No noise;
  • No water tank so no leakages.

Choosing a dehumidifier for your car can be a daunting task as you need to take into account various features that will affect your purchase – from the size and type of dehumidifier to the price.

Why do I need a dehumidifier in my car?

Car dehumidifiers are essential for anyone who wants to keep their car clean and free of mold.

5 Best Dehumidifiers for Cars to Keep Your Air Fresh (Winter 2023)
When it comes to car dehumidifiers, placement is key.

Dehumidifiers are most effective when placed in areas where there is little or no air movement, such as:

  • In the trunk: Trunks are one of the best places to install dehumidifiers as they are typically dark and humid. By placing a dehumidifier in your trunk, you can prevent mold and mildew from forming on your belongings.
  • Under the seats: Another great place to install a dehumidifier is under your car seats. This will help to remove moisture from the upholstery and keep your car seats dry and comfortable.
  • In the glove box: The glove box is another ideal spot for a dehumidifier as it is often one of the most humid areas in the car. A dehumidifier placed in the glove box will help to keep your belongings dry and prevent mold and mildew from forming.
  • On the dashboard: You can also place a dehumidifier on your car’s dashboard. This is a great option if you want to avoid window fogging, as the dehumidifier will start working immediately. Plus, it’s easy to check on the dehumidifier and see when it needs to be emptied.
  • At the back window: Keeping the back window clear can also be a challenge, especially for those without rear window defrosters. Dehumidifiers placed on the back window ledge can help prevent fogging.

Type of Dehumidifiers for Cars

5 Best Dehumidifiers for Cars to Keep Your Air Fresh (Winter 2023)
When it comes to car dehumidifiers for cars, there are two main types – electric 12V dehumidifiers and chemical dehumidifiers.
  • Electric 12V Dehumidifiers: Electric 12V dehumidifiers are the most popular type of car dehumidifier as they are easy to use and require no installation. Simply plug the dehumidifier into your car’s cigarette lighter socket and let it run.
  • Chemical Dehumidifiers: Chemical dehumidifiers work by absorbing moisture from the air and trapping it in a porous material. These dehumidifiers are more effective than electric 12V dehumidifiers, but they can be more difficult to use. They are mostly renewable, so you don’t have to worry about them running out of power and harming the environment.

Reusable vs. Disposable

Dehumidifiers can either be reusable or disposable. Obviously, electric dehumidifiers are reusable, but did you know that some chemical dehumidifiers can be reused as well?

If you want a reusable dehumidifier, be sure to choose one that has an indicator light to let you know when it’s full. You’ll also want to make sure the dehumidifier has an easy-to-empty tank and a fast recharge time.

On the other hand, if you don’t want to worry about recharging or emptying a dehumidifier, a disposable one might be a better option for you. Just be sure to choose a dehumidifier with a high moisture capacity so you don’t have to replace it too often.

Coverage Area

The coverage area is the size of the space that the dehumidifier can effectively remove moisture from. When choosing a dehumidifier for your car, be sure to consider the size of your car and the level of humidity you want to remove.

Noise Level

Noise level is an important consideration when choosing a car dehumidifier. Some dehumidifiers can be quite loud, which can be distracting or even annoying. If you want a quiet dehumidifier, look for one with a low noise level. Alternatively, you can choose a chemical dehumidifier, as they tend to be much quieter than electric dehumidifiers.

Dehumidification Capacity

The dehumidification capacity is the amount of moisture that the dehumidifier can remove from the air per day. This is usually measured in ounces or liters. Be sure to choose a dehumidifier with a high dehumidification capacity if you live in a humid climate or if you want to remove a large amount of moisture from your car.

Likewise, if you have a large car, you’ll want to choose a dehumidifier that is big enough to cover the entire car.

Price

Dehumidifiers can range in price from around $20 to $200. The price will depend on the type of dehumidifier, the coverage area, and the dehumidification capacity. In general, the more expensive dehumidifiers are more effective and have higher dehumidification capacities. However, there are some great budget-friendly options available that will still do a good job of removing moisture from your car.
