Comprehensive Review


The Eva-dry E-500 has an oval shape. Its shape and design reduce the risks of spillage of the silica gel beads (desiccants) in the dehumidifier. It has a small compact design, which also makes it suitable for both small spaces and relatively large rooms.

Aside from that, another unique feature of the E-500 design is that it has a hook at the upper part.

You can use the hook to hang the dehumidifier in your closet, wardrobe, or anywhere else in your home to ease air circulation and effective adsorption of humidity from the air. This feature also ensures that you can keep the dehumidifier out of reach of children and pets.

Area Coverage

This dehumidifier was designed to be used in areas of up to 500 cubic feet. It can be used in smaller spaces comfortably but will not effectively eliminate humidity from rooms that are over 500 cubic feet.

While you might notice a change in the humidity levels if you use it in a larger room, the changes will be quite slow and that can be frustrating especially if you want a quick result. As such, we recommend using this dehumidifier in areas that are 500 cubic feet or less.

Functionality/Moisture Removal Rate

The E-500 Eva-dry dehumidifier removes approximately 6 to 8 ounces of moisture from the air every 4 to 8 weeks. It has a higher moisture removal capacity than its counterpart the Eva-dry E-333, which removes about 4 to 6 ounces of moisture from the air after every 2 to 4 weeks.

If you are looking for a smaller dehumidifier for closets and other tiny spaces in your home, the Eva-dry E-333 would be a great and much cheaper option when compared to the Eva-dry E-500.


While the company indicates that this dehumidifier should be used in areas of up to 500 cubic feet, there are several spaces around your home where you can use this dehumidifier comfortably.

Some of the common areas that could benefit from the functionality of this dehumidifier include the area under the kitchen sink or bathroom sink, gym cabinets, small to medium closets or wardrobes, large toolboxes, small bathrooms, a safe with valuable jewelry or documents, or a boat’s cabin.

It is important to note that, the Eva-dry E-500 just like any other home-based dehumidifier is not the right device for eliminating excess moisture and water from home after floods.

If your home has been filled with water after a flood, you should consider alternative options for eliminating the water and cleaning your home because a dehumidifier would take a very long time to reduce the humidity levels in the home.

Silica Gel Beads Technology

The Eva-dry E-500 uses silica gel beads technology. You will notice that the beads are orange when the dehumidifier is fully charged. The silica gel beads absorb moisture from the air and retain the moisture.

When they are fully saturated, the beads will turn a dark green color, which will help you know that you need to recharge the dehumidifier. Once the beads are fully saturated, you should charge the dehumidifier.


The Eva-dry E-500 requires about 14 hours to get fully charged. To know if your dehumidifier is fully charged, simply check if the silica gel beads have turned from green to orange. After the dehumidifier is fully charged, you can comfortably use it for 30 to 40 days before recharging it.


The Eva-dry E-500 comes with a 5-year warranty. If within this duration you notice any mechanical issues with your dehumidifier, you should call customer support or the manufacturer for a consult.

According to customers’ reviews and tests conducted by the manufacturer, this dehumidifier can function properly for up to 10 years without any issues.

You should note that the warranty does not cover any repairs that might occur if you drop the dehumidifier and ruin it or if you attempt to open the internal parts of the dehumidifier yourself and ruin it in the process.

Ensure that your warranty is still valid before reaching out to the manufacturer.


• A great option for travelling to areas without electricity because it can last for up to 40 days without recharging
• Uses renewable silica gel beads which can be recharged after they become saturated with humidity.
• The design of this dehumidifier makes it leak-proof
• It is child and pet friendly
• Has a 5-year warranty
• Slightly more powerful than the Eva-dry E-333
• According to the manufacturers, this dehumidifier can last for 10 years life span
• Has a higher moisture holding capacity than the Eva-dry 333
• It is 100% cordless
• It does not use batteries


• The main downside of buying this dehumidifier is that it requires a longer charging time, which can be frustrating if you are about to leave your home and you have not recharged it yet.
• It is also slightly more expensive than the Eva-dry E-333, which is a smaller dehumidifier from the same brand.
• If you are looking for a dehumidifier for a large home, this might not be a great option as it is suitable for rooms of up to 500 cubic feet.

Final Verdict

Other than the three drawbacks, the Eva-dry E-500 is a great dehumidifier that will serve you well and will effectively reduce the humidity levels in your home. The Eva-dry E-500 is a great rechargeable cordless dehumidifier.

If you are looking for a dehumidifier for a tiny space that is approximately 300 cubic feet, you might benefit from the Eva-dry E-333, which is a smaller rechargeable cordless dehumidifier that offers almost the same performance as the Eva-dry E-500.


Are Eva-dry dehumidifiers safe?

Eva-dry dehumidifiers are safe. They use eco-friendly silica gel technology to absorb moisture from the air. They are also child and pet-friendly/safe because the design of the dehumidifier does not allow you, a child or a pet to access the silica gel beads.

How do I know if my Eva-dry dehumidifier is working?

There are several ways that you can tell if your Eva-dry dehumidifier is working. First, you can assess the humidity levels in your home before by using a hygrometer. A hygrometer is a device that measures the amount of moisture or vapor in the air, confined spaces, or soil.

Another approach is observing the color change of the crystal beads (silica gel beads) in your dehumidifier. The Eva-dry dehumidifier has an indicator window that you can use to assess the changes in the silica gel beads.

If the beads turn from orange to green after a few days, then that is an indication that they are removing moisture from the air.

You should note that you will not notice the color change within the first few hours of using the dehumidifier because the dehumidifier has been designed to last for 30 to 40 days before the silica gel beads get saturated.

If you buy a dehumidifier that has beads that are green that could indicate that the dehumidifier has already absorbed moisture from its surrounding. Simply recharge the dehumidifier for about 14 hours or until the silica gel beads turn orange and it will be ready to use.

There is a very low chance that you will buy a dehumidifier that has already absorbed moisture from the air because the packaging of the dehumidifier does not allow entry of moist air.

What happens if you leave Eva-dry plugged in?

If you leave the Eva-dry rechargeable dehumidifier plugged in for a long time defeats the purpose of having a rechargeable dehumidifier and can slowly harm your dehumidifier.

The silica gel beads get recharged through an electric dehydration process. If you develop the habit of leaving your dehumidifier plugged in for long hours, the plastic material might warp over time.

Although I have not seen or heard of instances where leaving the dehumidifier plugged in has caused a fire or any other accident in the home, I believe that it is important to stick to the manufacturer’s recharging instructions and avoid overcharging the dehumidifier.

How long do cordless dehumidifiers last?

Cordless dehumidifiers can last for a long time depending on how you care for your dehumidifier. For instance, the Eva-dry E-500 can last up to 10 years. If you are in the habit of dropping the dehumidifier, it might not last for the estimated 10-year duration.

If you take care of your dehumidifier, it might last for more than 10 years.
