1. Tips for Buying a Dehumidifier for the Humid Season
Consumers should focus on the water tank capacity and noise level when choosing a dehumidifier for their family.
Humid weather is a characteristic weather phenomenon of the eastern part of the Northeast region, when the moisture density in the air exceeds 90%, about 0.9 liters of water per cubic meter of air. This excess water will then condense into droplets, sticking to the walls of the house, clothes, and especially the ground, causing discomfort in people's daily lives as well as potential risks of respiratory diseases. Besides air conditioning, dehumidifiers can almost completely handle the humid condition in the house.
Dehumidifiers are constructed based on a principle somewhat similar to air conditioners, where they extract moisture from the air and pass it through a cooling system to condense it into water. However, this is a device that air conditioners cannot replace because the dehumidification feature in air conditioners is not really efficient as it is only a supplementary feature. Moreover, using air conditioning to dehumidify causes significant waste of electricity. In addition, air conditioners usually do not have a hygrometer so they can only operate based on relative humidity, based on standard temperature. Therefore, it will not operate when the room temperature has reached the set level. This makes the humidity level can quickly increase again and make the air in the room more stuffy. Dehumidifiers also have a higher mobility as they can be moved to every corner of the house as desired.
Users currently have many choices of dehumidifiers. However, basically there are two types, devices using a rotor and condensing dehumidifiers.
Rotor dehumidifiers operate on the principle of moisture absorption and evaporation, suitable for environments with high humidity and low temperatures, with high accuracy and large capacity. However, due to their large size and high cost, this type of machine is usually used mainly in warehouses, storage rooms of factories or areas with many electronic components.
The condensing dehumidifier operates on the principle of cooling moist air and condensing it into water. This type of machine operates with relatively high accuracy, but has the ability to dehumidify at different levels, small in size so it is more suitable for households. This line of machines is also divided into two small types, electronic control and mechanical control (using pressure relief).
Water tank capacity is the first factor to consider when buying a dehumidifier.
Consider the power and noise level when deciding which one to buy.
When deciding which one to buy, users should also consider two main factors: power and noise.
The power of the dehumidifier is characterized by the amount of water it absorbs per day, measured in liters. Small rooms under 15m2 should use machines with a capacity of less than 7 liters/day, under 20m2 use machines with a capacity from 7 to 14 liters/day, and larger rooms should use machines with a capacity of over 15 liters/day.
Noise is also an important factor to consider when buying because some types of machines suitable for bedrooms and living rooms in the house have a maximum noise level of only 48dB. However, some devices have a maximum noise level of up to 60dB, only suitable for warehouses or separate rooms. Many people have been disappointed when they accidentally bought a dehumidifier with high noise levels, which cannot be used while sleeping.
In addition, other accompanying features of the machine such as automatic or continuous dehumidification, air blowing, clothes drying, timer, bacteria elimination, and odor removal with ions... should also be considered. However, in reality, users often cannot use all the features that come with the device.
In the current market, various dehumidifier models are being sold and advertised at electronics stores as well as online shopping websites. With a few hundred thousand to over a million dong, users can buy portable, compact dehumidifiers like Dehumidifier, Tiross... Higher-end, there are product lines from Edison, FujiE, Daiwa, Coway, Electrolux... with prices ranging from a few million to nearly ten million dong.
However, there is another option that many people are interested in, which is the domestic dehumidifier models originating from Japan of brands such as Sharp, Mitsubishi, Panasonic... They are priced ranging from 2 to 3 million dong to nearly ten million dong, depending on the capacity and whether the machine is old or new. Electricity savings, high durability, and diversity in accompanying features are also the characteristics of this line of devices.
