Comprehensive Review

Shape and Size

The E-333 is a small compact dehumidifier. It has a rectangular shape, which structurally differentiates it from the Eva-dry E-500. The rectangular shape makes it easy to balance the dehumidifier on any flat surface, without worrying about it tipping over.

It has a minimalistic feel because of its small size and can fit in many small spaces within your home. It weighs 1.2 pounds, which makes it a lightweight dehumidifier that you can carry around in your gym bag or when you are travelling.

The E-333 also has a hook that can be used to hang it on wardrobe rails, bathrooms, gym lockers, or any other small spaces that you might wish to use the dehumidifier.

The hook ensures that the dehumidifier will offer you maximum performance by improving air circulation around the dehumidifier.

Area Coverage

The Eva-dry E-333 was designed for rooms and spaces of up to 333 cubic feet. The incorporation of the cubic feet value on the model’s number makes it easy for you to determine the capacity of the dehumidifier when comparing it with other options such as the E-500, which was designed for spaces of up to 500 cubic feet.

Functionality/Moisture Removal Rate

This dehumidifier removes about 4 to 6 ounces of moisture from the air for a period of 4 to 8 weeks. It has a low moisture removal capacity when compared to the E-500, which makes the E-333 unsuitable for large rooms or spaces.

Despite its small size, it is powerful and will offer you great performance if you stick to using it in small spaces of up to 333 cubic feet.


It is easy to use. All you will have to do after buying your unit is turn on the dehumidifier and leave it to do its work. You do not have to keep it plugged into an electric outlet.

Since the Eva-dry E-333 was designed for small spaces, some of the areas where you can use the dehumidifier include, drawers, kitchen cabinets, under the sink, small bathrooms, small safes that might contain jewelry and important documents, gym bags, and gym lockers.

You can also use the dehumidifier in music instrument lockers, gun safes, office supply lockers, small basements, and in your bedroom to reduce the level of humidity if you have a relatively small-sized bedroom.

It is important to note that this dehumidifier will not offer you optimal performance if you use it in a room that has very high levels of humidity such as a recently flooded home that has not been cleared.

It would also not be a suitable option for drying your laundry indoors. Aside from tiny spaces, you can use this dehumidifier in a mildly humid room or remove unpleasant odors from the air.

Silica Gel Beads Technology

This dehumidifier uses silica gel desiccants (drying agents) to absorb moisture from the air. The beads absorb moisture and hold as much water content as they can before they become saturated and in need of recharging.

These silica gel beads can absorb up to 40 percent of their weight in moisture because of the nature of the silicon dioxide molecules.

The silica gel beads used in the dehumidifier are similar to those used in clothing or food packaging to keep excess moisture from ruining the quality of the product.


The Eva-dry E-333 will need to be recharged after using it for about 20 to 30 days. You will notice that after this period of time the silica gel beads in the dehumidifier will start turning green. When they attain a dark green color that will be an indication that the beads are saturated and the dehumidifier needs to be recharged.

You will need to recharge the dehumidifier for approximately 10 to 12 hours according to the recommendations provided by the manufacturer.

Avoid recharging your dehumidifier for shorter hours as the silica gel beads will not dry well and you will not get maximum performance from the dehumidifier.


This dehumidifier has been made with environmental friendly silica gel beads and does not contain toxic chemicals. It is also leak-proof, so you do not need to worry about leaks, spills, or any messes. The silica gel beads are not exposed, which reduces the risks of choking hazards and makes this dehumidifier safe for children and pets.


The Eva-dry E-333 comes with a five-year warranty, which ensures that you can get your dehumidifier repaired or replaced within the period if you notice any manufacturing faults that might affect the dehumidifier’s performance.

How does the Eva-dry 333 work?

The Eva-dry E-333 works by absorbing excess humidity from the air. It is a desiccant dehumidifier and uses silica gel technology.

The silica gel beads in the dehumidifier absorb moisture within their structure and can hold up to 40 percent of their weight in moisture. When you recharge the dehumidifier, the silica gel beads dry and after that, they are ready to absorb more water.

How long does it take to recharge an Eva-dry dehumidifier?

Different Eva-dry dehumidifiers have varying charging durations. For instance, when using the Eva-dry E-333, it takes approximately 10 to 12 hours to recharge the dehumidifier after the silica gel beads are fully saturated and have turned green.

If you recharge the dehumidifier before the silica gel beads are completely saturated, the recharging time will be significantly shorter.
