Top 5 Peltier Dehumidifiers Review 2021
Pro Breeze FBA_PB-03-US – Editor’s Choice
Coverage area: up to 220 sq. ft.
Dehumidification performance at AHAM: 0.14 gal/day
Tank capacity: 0.4 gal
Dimensions: 6.6 x 9 x 12.7 inches
More features: Lightweight, compact and portable; Auto shut-off
Our best Peltier dehumidifier, rated as our Editor’s Choice, is an excellent combination of features: it’s compact but effective and we think it’s a sleek design you’ll be proud to use in any room without ruining your aesthetics.
This one can remove 18oz of moisture per day—that’s quite a few cups! We love that it has an auto shut-off feature which will kick in when the tank is full. That makes it a safe device that doesn’t require much effort: you don’t have to monitor it the whole time just to prevent overflows.
This also makes it energy efficient because you know it won’t stay switched on without having any effect on the room. The device itself also uses less power than some other models, so if you’re concerned about your carbon footprint, this is a model to look at.
When you need to empty the tank, simply take it out and pull out the plug so the water can run into a drain or sink. That’s less messy than splashing the water all over yourself because you’re tipping over a large tank.
Know that it’s designed for rooms up to 2200 cubic feet, making it appropriate for rooms, caravans, closets and more. However, its compact design makes it a suitable choice for smaller spaces as well, so you can even use it as a grow tent dehumidifier.
Yes, it’s quiet as most high-end Peltier dehumidifiers are, so you can even place it on your office while you work without it disturbing you.
Note that this one is sensitive to temperature: you won’t be able to use it in very cold rooms. Anything below 41°F and it won’t work.
Ivation Small-Area Compact Dehumidifier – Best Smart Memory
Coverage area: not specified
Dehumidification performance at AHAM: 0.54 gal/day
Tank capacity: 0.7 gal
Dimensions: 9.4 x 7.5 x 17 inches
More features: Cooling circulation system; Smart memory
This square design is a great space saver, even though it’s a bit bigger than some models, because you won’t lose any floor space unnecessarily: there are no odd angles so it’s easy to fit it next to other items on the floor or a shelf. In small spaces such as attics you’re still likely to fit this inside.
Here’s another example of energy efficiency in this niche of dehumidifiers: this model even has an Auto-humidistat. It detects when it’s necessary for the device to run, based on the humidity around it. That means power is only used when necessary. You simply need to program it, so it knows at which RH level it needs to operate.
This one contains some innovative technology because it can even remember some of your settings, such as the fan speed you prefer. If you have a power outage and the machine comes on again it will remember your preferences and continue working accordingly. That’s why we named it our Best Smart Dehumidifier.
If you want low maintenance, you’ve got it. This one comes with a drain hose so you can let the water run out automatically. If you don’t have a place for the water to drain into in the room you use it in, simply use the water tank feature. We love that the machine will automatically switch off when the tank is removed, so there’s no chance of a mess.
It’s more expensive than the Pro Breeze above, but the extra features justify the expense.
Dehumidification performance at AHAM: 0.16 gal/day
Tank capacity: 0.52 gal
Dimensions: 6.8 x 8.5 x 14 inches
More features: Compressor based dehumidifier contains a pressurized refrigerant
Eva-Dry is a popular brand and we love that they make similar products with different capacities. It enables you to shop according to your needs.
We picked the Edv-2200, but you can also consider the smaller model, the Edv-1100. Both work efficiently, but the Edv-1100 Electric Petite Dehumidifier just has a different capacity. The model is small enough to carry in one hand. The Edv-2200 is also compact and will work well for areas up to 2200 cubic feet.
Consider the modern design. This thermoelectric dehumidifier will look stylish so you can even use it in your office or living room.
Though it’s simple to use, it comes with impressive technology: this one will shut off when the reservoir is filled to capacity. There’s also a light that signals you when it’s full, so you know when to empty it. This is better than having to check manually.
It’s important to note that this was designed with the focus on helping people manage humidity in RVs or in boats, not necessarily large rooms. But yes, you can use it in your home too. We saw that this unit may take a little longer than some other models to dehumidify the air, but it does work.
It works with a power cord, so make sure there’s a power source where you need to use it.
More features: included drain hose, switchable fan speed & programmable timer
Here’s another model with an impressive design: the smooth, white front panel will look ultra-modern and be inconspicuous between other features in your home or office.
The brand gives you more than one option for discarding the water: take out the tank or simply attach a hose for drainage. Yes, the hose is included in your purchase!
When you’re moving your dehumidifier around the house it will also be effortless because this one has a recessed handle. That makes it easy and safe to carry, resulting in it being our customers’ choice. At almost 25lb it’s heavier than some others on our list, but still manageable.
Note that this one is meant for smaller spaces than some others on our list, but it’s still impressive when doing what it’s designed to do: capturing moisture in rooms of 1056ft².
Because it’s a Peltier dehumidifier it runs quiet, but note that the alarm—which tells you when the tank is full—is quite loud. If you place this in your room and it fills up quickly, the long beeping may wake you during the night.
This is one of the smart options on our list, because you can pick different fan speeds, it has an auto-off function and you can pick the humidity level you prefer. On the user friendly control panel you can control all of this.
What makes it special?
Recessed handle for easy carrying
Large capacity and impressive performance
What cons did we find?
Beeping is loud
Not best performance on our list
RINKMO Portable Mini Dehumidifiers – Budget Pick
Coverage area: up to 215 sq. ft.
Dehumidification performance at AHAM: 0.15 gal/day
Tank capacity: 0.63 gal
Dimensions: 7.5 x 7.5 x 13 inches
More features: Whisper quiet and energy efficient
You can still get one of the best Peltier dehumidifiers at a reasonable price. From RINKMO you get a portable unit with a unique design: the unique shape will look stylish in your home or office and the LED lights add to its charm. The shape also makes it easy to place it in a corner area without losing too much floor space.
Special note: the LEDs are very bright so turn them away from you if you’re using this at night and you don’t want the light to bother you. At least it runs quiet so the sound won’t keep you awake.
For a budget pick it has impressive features, such as an auto-off and you can even set the desired humidity level you want it to maintain. Bonus: it tells you the humidity in the room so you don’t need another device to measure this.
This one is easy to carry around the room or house because it weighs only 4.6lb. With the recessed handle it’s effortless and safe; you won’t drop it. It’s also safe because it will switch off when the tank is full so there’s no risk of spills or overflow.
This is not ideal for large rooms, as it’s meant for compact spaces. For this price, you’re getting great value for money though.
Peltier dehumidifiers can be the easy answer to caring for your home and your health. Don’t give mold and bacteria a chance to grow. But you need to pick the right type for your unique application if you want to get value for money. Our buying guide will make you understand the market better and shop like a pro.
What is Peltier technology?
With Peltier technology, a dehumidifier pulls moisture from the air in a unique way. A Peltier dehumidifier can also be called a thermoelectric dehumidifier as it creates thermoelectric energy. Voltage is applied across different metals. This results in temperature differences and this is called the Peltier effect.
In the dehumidifiers we reviewed, power is used to create a cold zone and a hot zone in one appliance. You need the cold surface for water from humid air to condense so you can collect it. This is how moisture is removed from air. The hot panel will heat up the air again before it exits the Peltier dehumidifier.
In a Peltier dehumidifier the air is pulled inwards and forced past the cold and hot zones thanks to the fan inside the appliance.
Features to consider while choosing a Peltier dehumidifier
You’ll find many Peltier dehumidifier models on today’s market. So, how do you identify the best option for your home? We listed the main features to consider and we’ll tell you how you’ll know which type is worth the buy.
One of the first things you need to do is to decide which room in your home or office needs the dehumidifier. Measure the space and then get shopping.
Each dehumidifier can only work for a certain amount of space. Aspects such as size of the unit affect how much air it can work for effectively.
This specification should be listed with the unit’s details, as can be seen with the Eva-Dry Edv-2200 that will work for spaces up to 2200 cubic feet. It’s important to look at both the floor space and the cubic feet it’s appropriate for, because a room’s height and layout will affect efficiency.
If you purchase a small unit to save money and then place it in a large room, the air simply won’t become as dry as you prefer it to be.
You can see from our list that Peltier dehumidifiers are mostly small in size. Note that they’re not designed for large rooms but rather created for small spaces, such as cupboards, small bathrooms or smaller sized bedrooms. You can use them in other spaces, but won’t get the same results you’ll see with other types of dehumidifiers.
You need to have an idea of how much moisture will be extracted from the air. Most Peltier dehumidifiers can only extract a certain amount each day. Do you need one that can perform impressively like the Inofia model above, or will one with a lower performance — less moisture extracted per day — suffice? Can it do what you need it to do?
You will need to empty it in order for the unit to keep working effectively and not overflow. You don’t want to run to your dehumidifier every now and then simply to empty the tank, do you?
A larger tank is an asset and manufacturers try their best to add these bigger tanks while still keeping a compact design, as can be seen in the Inofia 30 Pints Dehumidifier.
In a very humid bathroom the tank is bound to fill up faster than when you place the unit in a closet or room. You need to determine how humid the air is as well as the size of the space to determine which tank will suit you best: pick a compact dehumidifier that you don’t have to empty too often.
Dimensions and weight
Where do you want to place your dehumidifier and will you often relocate it?
Size and weight of your Peltier dehumidifier determine where you’ll be able to store it, whether it will take up too much space on a counter or in a cupboard and whether you can easily carry it from room to room. If you know you’ll be using it in various spaces in your house it’s better to go for a light item that’s not cumbersome to carry. If you need it for health reasons you may also want to consider a unit small enough to travel with.
Also see how much space you have for storage so your new appliance doesn’t rob your of cupboard space during months you don’t use it. If you’re going to use it in a specific place such as your bathroom, measure out the available space on a shelf or wherever it will be out of the way. Pick a size that fits this space, so your new dehumidifier doesn’t clutter the room or rob you of floor space.
Also, if you’re opting for a unit with a drainage system like the Ivation Small-Area Compact Dehumidifier, what available space do you have next to the drain. Will your new unit fit?
A humidistat isn’t a prerequisite, but a handy extra if it’s built into your new dehumidifier. The humidistat measures the humidity in the room throughout. The collected data can be used to determine when it’s necessary for the appliance to start working. If humidity rises above a certain level, the unit can switch on and start extracting moisture.
You’ll see this technology in the Peltier dehumidifier review of the Ivation model above.
This makes for effortless usage since you don’t have to switch it on yourself whenever the humidity is high.
You need to make sure there’s a warranty in place, as with all electrical devices. You may have to test it to see if it works for your unique setup. It’s handy if there’s a return policy you can use.
Peltier dehumidifiers are simple appliances and that’s part of their attraction. But consider investing in those with additional features to give you even more value for money. For instance, if your unit requires an outlet and the purchase includes a hose it means you have everything you need on hand.
You may also enjoy a more modern, high-end unit with a control panel that makes it easier to monitor.
To make sure you get a unit that will function as promised, a certification always gives some peace of mind.
How to keep your dehumidifier in top condition
Apart from emptying the water tank you also need to keep your dehumidifier clean. You don’t want dust and grime to clog the unit. So, give it a wipe down regularly.
It’s also smart to keep the room clean where you’re using your dehumidifier: if the air movement causes dust to swirl around it may end up in the dehumidifier and block inlets or outlets when it mixes with the water.
When dehumidifiers ice up it’s often because they’re operating in colder temperatures than they’re designed for. Perhaps the corner it stands in doesn’t have enough circulation, so move it away from the walls. Alternatively, it may simply be too low; elevating it by placing it on a counter can fix the problem, because warm air rises.
A Peltier dehumidifier is a quieter appliance compared to many other dehumidifiers. In part this is because there are no heavy machine parts that move while it works, except for the fan. You’ll hear some sounds, but some units are quiet enough to use in your room while you sleep.
Yes, Peltier dehumidifiers are easy to clean. Unlike other dehumidifiers, such as compressor types, you can easily remove the components that require cleaning. This is usually the filter and the tank. This makes for easy cleaning at a basin. Apart from this you don’t have to do much maintenance on them.
We looked at all the specs in our Peltier dehumidifier reviews and chose the following three as our winners. Firstly, the Pro Breeze FBA PB-03-US came out on top with 9.7 out of 10 because it’s such a good mix of features. It’s easy to use, energy efficient and even looks great.
If you prefer a model with a drainage hose, you’ll love our second choice. The Ivation Small Area Compact Dehumidifier is easy to drain and it has impressive technology so you can set your preferences. That earns it a 9.6 rating.
From Eva-Dry comes our third option with a rating of 9.3. Remember that this brand gives more than one size option, making it easy to get one that works for your unique setup.
You can see there’s the best Peltier dehumidifier for every scenario. Which one will you get to create a healthier home environment?
