The Best Small Dehumidifier For Home and Office Use

Updated on

The best small dehumidifier offers quite a number of benefits. Dehumidifiers help lower the level of humidity and as a result, they reduce the chances of mold, mildew and odors. They also often recommended to those with allergies as they circulate the air, filter bacteria. And prevent dust from dispersing through the air and this, in turn, can reduce the symptoms of your allergies. A small dehumidifier is an ideal choice for small rooms and areas but they also tend to be a lot more affordable, lighter and quieter compared to regular dehumidifiers.

What makes them quieter is that they use a technology known as Peltier which is thermoelectric. It absorbs heat on one side and evaporates it on the other hence while one side heats up the other stays cool and this temperature difference is what creates the dehumidification.

The downside of small dehumidifiers is that they tend not to function as well in colder temperatures. Additionally, because of their size, they have a limited capacity as most reservoirs can only hold anything under 20 ounces depending on the dehumidifier.

If you’re not sure where to start when it comes to buying the best small dehumidifier, we’ve gone ahead and listed some of the 5 best options below.

  • 100% CORDLESS DEHUMIDIFIER: Moisture out: Cords out! No cables or...

This is the smallest dehumidifier on our list. At the size of 5.5” wide and 2.5” thick, it is small enough to fit anywhere. It can be mounted or hang on a hook.

The affordable price might lead you to believe that it is disposable however the Eva dry has a small window on the front which changes color when the beads inside have soaked up as much moisture as they can hold. The length depends on the conditions of the area however for most people it tends to be every couple of months. Additionally, you only need to have it plugged in for 12 to 14 hours daily.

Another great feature of this product is that the silica beads found in the system can actually last for up to 10 years. The Eva Dry E-333 is an ideal choice if you have a space that is under 500 cubic feet and experiences excess moisture. Eva Dry also offers 5 year guarantee which is pretty great considering how affordable their product is.

Something else that’s pretty great about mini dehumidifier is that its completely cordless so all you’ll need to do is charge your device. You don’t need any cables and batteries as the mini dehumidifier can last for about 20-30 days before its next recharge. It also doesn’t have a water tank that needs to be empties.

It's ideal for confined spaces and storage unites where you might want to leave a dehumidifier for an extended period of time. It can also be used in spaces such as a closet, bedroom or car

It uses a renewable silica gel which allows the mini dehumidifier not to heat up the air. The moisture in the air is instead absorbed and contained within the gel and can be left for up to a month before the gel need renewal though this is highly dependent on where you live and the humidity levels. When the dehumidifier reaches the maximum 4-6 ounce capacity, the silica gel crystals change color from orange to red. The Eva dry has a window at the from which allows you to easily check and see the color of the crystals . When they turn green all you need to do is simply plug the Eva dry into an electric outlet and leave it for about 8 to 10 hours. A small, low energy heat pad dries and revitalizes the crystals hence allowing the dehumidifier to be ready to work. It can do this for about 10 years.

It can also be used around children or pets as the Eva-Dry won’t leak or spill, even when at full capacity.

Dehumidifier vs air purifier

They are both designed to minimize allergens and pollutants in a room and are quite helpful to those who suffer from allergies and respiratory conditions.

The differences come in how they are used. Dehumidifiers are designed to remove excess moisture in the air. This in turn helps reduce the buildup of any airborne mold, dust mites and other allergenic organisms. An air purifier circulates air through HEPA (High Efficiency Particulate Air) filters with the aim to remove up to at least 99.97% of common pollutants like dust, pollen, mold, pollen, odors etc. Though most common filters can only remove large airborne particles, air purifiers can eliminate smaller ones, too. Air purifiers have no effect in reducing the humidity level in the air.

What Should You Look For When Buying A Small Dehumidifier

When you live or work in a humid area, some of the things you might begin to notice is that your house or office smells musty and damp. This can result in the growth of mold and mildew and is the perfect environment for common allergy triggers. This is where a dehumidifier comes in and a small dehumidifier at that especially if you’re looking for something that is portable, light and compact. So what are some of the things you need to keep an eye out when searching for one? Well, we created a buyer’s guide that we believe will help point you in the right direction.

a) Size

Small dehumidifiers come in different sizes and styles. Some are designed such that they can be placed on a bedside table while others can be in the corner of a room or in a bathroom or hang on a hook.

Before choosing the best dehumidifiers, you should first consider where you’d like to use it and place it. A compact, lightweight dehumidifier is an ideal choice for offices and RVs also known as mobile homes. A slightly larger unit will be ideal for bedrooms, laundry rooms, nurseries and bathrooms.

The size of the dehumidifier should also match the needs the moisture removal. Large capacity units can emit more than 40 pints of water per day, medium-capacity units can emit from 30 to 35 pints per day, while small capacity units can remove between 20 and 25 pints of per daily.

b) Room Coverage

When thinking of purchasing a small dehumidifier, room coverage is key. It is important to know and understand that most small dehumidifiers will not be able to cover larger or open rooms. Small dehumidifiers tend to cover up to 150 square feet while the larger ones will cover a little over 200 square feet. Other larger units can even cover up to 4,000 square feet.

c) Reservoir Capacity

Reservoir capacity is an important feature to consider as this is where all the water vapor is collected. Since the dehumidifier is small in size, the tanks are on the smaller size hence when choosing a unit, it is important to consider how humid the environment you are in is. A small reservoir will need to be emptied often if used in a high humidity area hence it would be more practical to go for a dehumidifier with a larger reservoir.

d) Eco-Friendliness

Choosing an eco-friendly product is not only good for the climate but also for your wallet. When selecting a small dehumidifier, choose one that is energy efficient as this means that it does need to run on electricity 24/7.

e) Cleaning

Dehumidifiers are created with filters that allow the air to pass through, and these filters eventually get dirty in time. When selecting a unit, you want one that has a notification that will alert you when its time to clean the filter.

f) The Style of The Dehumidifier

There are different types of dehumidifiers. The most popular style is the one that uses the refrigerant and has a compressor. As warm air passes across a surface cooled by a refrigerant, moisture is pulled from the air and collected in the machine.

There’s the Peltier or thermo-electric dehumidifier which is quieter than systems with a compressor. It uses a current, a heat sink and a fan to draw moisture from the room. They tend to be more affordable than a refrigerant-based dehumidifier and come in smaller sizes.

Lastly, there are the desiccant dehumidifiers. It collects water like a sponge and it quieter than dehumidifier with a compressor and puts off more heat but is limited when it comes to capacity. If you live in a warmer area or need a large system with a pump then a refrigerant would be an ideal choice. If size, humidity level and capacity are not a problem then a Peltier or desiccant dehumidifier would be an excellent choice.
