Best Peltier Dehumidifiers (Buying Guide & Reviews 2019)

Generally going under the name of “thermoelectric dehumidifier,” a Peltier dehumidifier works by creating thermoelectric energy – and using it to dry the humid air into our home. They are perfect for homes where humidity reaches an epic level.

Basically, with a Peltier dehumidifier, electricity is turned into the temperature – giving you hot air that is eventually transformed into the cold air. These temperature differences facilitate dehumidification – a fact that may (or may not) have been observed by scientist Jean Charles Athanase Peltier when he discovered the Peltier effect.

Whether or not he knew that his discovery would lead to the creation of best thermo electric dehumidifier, it is still uncertain. However, we do know that it played a great role. With all that, peltier dehumidifiers are still fairly difficult to understand – and the options make it rather difficult for us to choose.

To make things easier for you, we have compiled some peltier dehumidifiers reviews – as well as a buying guide. This way, making your choice should be quite easy.

How a Thermo-Electric Dehumidifier Works

How a Thermo-Electric Dehumidifier WorksThermoelectric dehumidifiers use a process called the “peltier effect.” This states that differences in temperature – particularly, the sudden changes – can turn energy into temperature and vice versa.

When it comes to Peltier technology, only one process is involved. The electricity goes through the dehumidifier’s module, creating a temperature difference. One module side heats up while the other cools down.

This is where the air is pushed through by means of a fan. The air that has been previously warmed up hits the cold side heat sink – causing the dehumidification to occur. The smooth, angled finish of the cold heat sink allows for the condensed water to drip into the tank – collecting it. The air is then released from the dehumidifier – and the process starts all over again.

Bear in mind that the dehumidifier releases the same air that has been pulled in – the difference being that the air is now “traveled” inside the dehumidifier. It goes through the entire peltier model, as well as its side heat sinks.

The air that comes out of these best small dehumidifiers is warm – but humidification-free. The hot sides warm the air up, preparing it for dehumidification – and the cold sides strip the humidity pit of the air. The result is an air that is relatively warmer – but also dryer.

Thermo-Electric Dehumidifier Advantages and Disadvantages

best thermo electric dehumidifier

There are several advantages and disadvantages to purchasing a dehumidifier that uses thermoelectric technology – which you ought to know about before making your purchase. Some advantages include the following:

  • They are very quiet

Thermoelectric dehumidifiers do not use compressors, which is why they have a very silent action. This makes them very convenient to use in a small bedroom, a bathroom – or any other place that you might want to keep quiet. Peltier dehumidifiers are even quieter than best desiccant dehumidifiers – and this is exactly why people use the first category.

You might hear some slight noise in a peltier dehumidifier – but that will only be coming from the fan. However, you should know that the fan is quite small – which is why you are not likely to hear anything significant from it. This is one of the reasons why the thermoelectric dehumidifier market is on the rise.

  • They are reliable

These top-notch dehumidifiers were basically made so that they will not break. They hardly have any moving parts – and the only one that they might have is the fan. For this reason, they are not very likely to break.

  • They are inexpensive

Peltier dehumidifiers are compact in size and used for small rooms, which is why they are also quite inexpensive. Some are even cheaper than desiccant dehumidifiers, which is why this category has become one of the most popular options.

  • They require little maintenance

For the same reason that boasts their reliability, peltier dehumidifiers need little to no maintenance. Compared to compressor dehumidifiers, they have no removable parts except for the tank and/or the filter – which is why they are very easy to clean.

  • They are portable

peltier dehumidifiers reviewsSince Peltier dehumidifiers are small and lightweight, they can easily be moved from one place to another. You may take them from the cupboard to the bathroom – or use them as the best gun safe dehumidifier.

Obviously, while thermo-electric dehumidifiers may have their advantages, there are also some disadvantages that you should weigh carefully:

  • They are not suitable for small rooms

Most Peltier dehumidifiers are not that good for small rooms. While there may be models that can reach up to 1000 square feet, they are generally effective only up to 250 feet – after which they can no longer extract anything.

  • They absorb less moisture than other types

While they do eventually absorb the moisture, they won’t do it as quickly as a refrigerant or desiccant type. You won’t have to empty the moisture tank as often – but if you live in a home with a very high humidity level, a peltier dehumidifier may be a poor choice for you.

  • They have a limited capacity

The tank of a peltier dehumidifier is a lot smaller than most standard units. You may find models that can reach up to 20 ounces, but most of them have a standard capacity of 16 ounces. They can last through the day and maybe a good part of the next one – but they will still have to be emptied often. They are not a good option if you are away from home a lot.

  • They don’t work in environments with high humidity

As mentioned above, a peltier humidifier will not work in a place with very high humidity – over 50-70%. While some modern peltier humidifiers have very strong power, most of them only work with slightly humid environments.

  • They don’t work in extreme temperatures

When it’s too cold or too hot, the humidity in the air becomes very high. When that happens, the thermo-electric humidifier will no longer be able to absorb the moisture – rendering the unit ineffective.
