Welcome to the NextLevelTips.com guide on the best dehumidifiers on the market!
Do you have a problem with excessive humidity in your home?
Are you considering buying one of the best domestic dehumidifiers but you don’t have the slightest idea on the way they work, and their most important features?
You’re in the right place!
The main goal of the best dehumidifiers is obviously to remove excess humidity from a room.
It can be used at home, at the office, in the basement, in your garage and in many other places.
Excessive humidity is an enemy that should not be underestimated!
In fact, remember that spending too much time in a very damp place can be harmful to your health and of those around you. An unhealthy environment can in fact cause allergies and rheumatism.
Not to mention that the walls would soon be covered with stains and mold and you will lose a lot of time and money for maintenance. That’s why it’s important to choose one of the best dehumidifiers!
If you live in an area with high humidity, buying a dehumidifier could be a good investment.
Best Dehumidifiers: Drying the Laundry
Another aspect of our everyday life where a dehumidifier can be useful is when drying the laundry.
It may seem irrelevant to you, but consider for example the following situations (which actually occur quite frequently):
- your home does not have enough outdoor space (in terms of terrace, garden, etc.) to be able to place a drying rack to dry your clothing
- or you have enough outdoor space, but it’s raining outside
In both these situations you will be forced to hang your washing inside, and this will increase your home humidity even more.
By purchasing one of the best dehumidifiers for home and basements, your rooms will remain dry and your clothes will dry out much faster.
Let’s then see together the most important features of home dehumidifiers!
What Are the Best Dehumidifiers For Home?
How to Choose The Best Dehumidifier?
When you are thinking of buying a dehumidifier, you need to keep these factors in mind:
- Noise Level: how silent the home dehumidifier is
- Energy Class
- Value for Money
What’s Dehumidifier Capacity?
The first parameter to take into consideration when choosing the best dehumidifier is capacity. Capacity indicates how many pints (or liters) of water your dehumidifier can extract from the air in 24 hours.
How can you understand the right capacity for your needs?
You must take these factors into account:
- the room size you need to dehumidify. The larger the size of the room, the greater the capacity must be.
- the average humidity rate present in the environment in which you live or work. The higher the humidity rate, the greater the capacity should be.
If the environment to be dehumidified is large or the humidity rate is high then it is better to consider a dehumidifier with a capacity of at least 40 pints (about 20 liters) per day.
Otherwise, you can also choose one with a lower range. For example, if the room where you put the dehumidifier is relatively small or if the humidity is not too high, you could opt for a capacity of 25 pints (about12 liters) per day.
Let’s also talk about the dehumidifier size: they are typically quite bulky!
Therefore, keep in mind:
- overall dimensions of the dehumidifier in terms of volume
- total weight of the dehumidifier
These features may not be all that important if you place your dehumidifier permanently in a room without ever moving it. However, if you plan to move the dehumidifier from one room to another, then you will have to consider buying a product that is not too difficult to move.
Best Dehumidifiers: Noise Level
The best dehumidifier must be a silent tool, so that you can carry out your daily activities like sleeping, relaxing, working or reading a book.
It would be rather annoying if, after buying a new product, you discovered that its noise constantly disturbs you. These devices must necessarily generate a bit of noise to work, but the best dehumidifiers for home are today characterized by low noise.
But let’s try to better understand what we mean by low noise.
You must know that the device noise is measured in decibels (symbol: dB). The greater the number of decibels, the more noisy the dehumidifier will be. Write down the noise level in decibels declared by the manufacturer, and limit your choice to those that are quieter (that is, that make less decibels of noise).
Nowadays dehumidifiers have different operating modes. Among these there is also silent mode. The best dehumidifiers on the market make about 37 dB of noise. They are so silent that they wouldn’t even disturb you while reading in a library!
Energy Saving Dehumidifiers
How much energy a dehumidifier uses to operate depends very much on the type of use you make of it. Energy efficiency is certainly one of the selection criteria that we must carefully consider.
In fact, consider that a dehumidifier could remain on for many hours a day and therefore we have to carefully consider its energy efficiency.
Don’t forget that saving energy is also positive in environmental terms!
Normally, as the capacity increases, power consumption also rises. From about 200 Watts for the smallest to 450 Watts for the 40 pint (about 20 liter) capacities per day. The principle of course is that the more powerful it is, the more energy it consumes.
The best dehumidifiers also have a control panel with which you can set the desired humidity level. This functionality has an important impact on overall energy consumption. Once the target is reached these dehumidifiers turn off automatically, thus avoiding wasting unnecessary power.
How Does a Dehumidifier Work?
Have you ever wondered how a dehumidifier works?
Dehumidifiers are based on two types of operation, namely mechanical-refrigeration and those with a Peltier effect.
Mechanical Refrigeration Dehumidifiers
This type of dehumidifiers is the most common and sold on the market.
Inside the dehumidifier there is a coil containing a coolant connected to a compressor exactly like in a kitchen refrigerator.
The coolant undergoes the following steps:
- The compressor compresses the liquid and consequently increases its temperature.
- The liquid passes into a coil and, being very hot, heats it up giving out much of its heat to the outside.
- The expansion of the liquid together with the previous heat loss produces a lowering of the temperature.
- the liquid flows into another coil it cools and begins to capture heat from the outside.
- The liquid re-enters the compressor again and the cycle starts again from point 1.
So there are two coils inside the dehumidifier: an hot one and a cold one.
A fan sucks air from external environment and pushes it towards the cooling coil, that is the cold one. As the water saturation vapor pressure decreases with decreasing temperature, the water vapor found in the air condenses on the cold coil.
The water drops that gradually form are conveyed towards a collection tank.
Instead the dehumidified air passes on the heating coil, that is, the warm one and returns approximately to the same inlet temperature.
As a last step, the air is filtered just before going out to remove dust and impurities.
The process described above is more efficient in conditions of high temperature and high relative humidity (greater than about 45%). Therefore this type of dehumidifiers is less suitable in geographic regions with more rigid climatic conditions.
Peltier Effect Dehumidifiers
Similarly to mechanical refrigeration dehumidifiers, even in this type of dehumidifiers a surface gets so cold that the air moisture condenses.
However, dehumidifiers based on the Peltier effect do not use compressors but instead include a Peltier cell.
The Peltier effect takes its name from its inventor and is the phenomenon whereby an electric current flowing between two different metals or semiconductors placed in contact through a junction produces a heat transfer.
The temperature difference between the two sides can also be 160 ° F (about 70 ° C).
The Peltier cells are very compact and are widely used in refrigerated minicells, in portable camping refrigerators or to cool PC components.
In the Peltier effect dehumidifiers a fan sucks air from external environment and passes it on the cold side of the cell obtaining the condensation of the water vapor. The water drops thus produced fall into a collecting tank.
The freshly produced dry air is conveyed towards the warm side absorbing heat and finally returned to the environment as dry air.
The Peltier effect dehumidifiers do not require any defrosting mechanism and consume a small amount of energy, moreover they are silent because they lack the most noisy component, that is compressor.
The only limitation of Peltier effect dehumidifiers is the relatively narrow range of action. They are therefore only suitable for small volumes such as a bathroom or a small room.
