Prolonged humid weather is a characteristic phenomenon in the Northern region, where the humidity exceeds 90%, about 0.9 liters of water per cubic meter of air. This water condenses into droplets, causing mold and discomfort, posing respiratory health risks.
1. Which type of dehumidifier is recommended for prolonged humid weather?
Apart from air conditioning, a dehumidifier can effectively eliminate persistent indoor humidity. Pay attention to the water tank capacity and noise level when choosing a dehumidifier for your family.
Prolonged humid weather is a characteristic weather condition in the Northern region of our country, with humidity exceeding 90%, equivalent to over 0.9 liters of water per cubic meter of air. This water condenses into droplets, clinging to walls, clothes, and especially the ground, causing mold and discomfort in living spaces and posing respiratory health risks.
After Tet, the Northern region experiences prolonged and uncomfortable humid weather. A solution to cope with this is to invest in a dehumidifier. This device operates on a principle similar to an air conditioner, extracting moisture from the air and passing it through a cooling system to condense it into water.
Using air conditioning to dehumidify can lead to significant energy waste. Moreover, air conditioners often lack a humidity sensor, relying on relative humidity and standard temperatures. They may not operate when the room temperature reaches the set level, allowing humidity to quickly rise again.
Users have a variety of dehumidifier options. However, there are fundamentally two types: rotor-based devices and condensation dehumidifiers.
Rotor-based devices operate by absorbing and evaporating moisture, suitable for high humidity and low-temperature environments, offering high precision and large capacity. However, they come with a higher price tag and are primarily used in warehouses or areas with many electronic components.
Condensation dehumidifiers work by cooling moist air and condensing it into water. This type operates with relatively high precision and can dehumidify at various levels. They are smaller in size, making them more suitable for household use. This category includes both electronically controlled and mechanically controlled (using pressure relief) devices.
When deciding which type to purchase, consider the two main factors: capacity and noise level.
The capacity of a dehumidifier is characterized by the amount of water it extracts per day, measured in liters. For rooms under 15 m2, it's advisable to use a unit with a capacity below 7 liters per day; for areas up to 20m2, opt for a device with a capacity ranging from 7 to 14 liters per day. Larger rooms should utilize a unit with a capacity exceeding 15 liters per day.
Noise level is also a crucial factor. Some devices have a maximum noise level of up to 60dB, suitable for warehouses or individual rooms but unsuitable for use during sleep.
Additionally, other features of the dehumidifier such as automatic or continuous dehumidification, air blowing, clothes drying, timer settings, bacteria elimination, and ion-based odor removal should be considered.
In today's market, a variety of dehumidifier models are available at electronic stores and online platforms. With prices ranging from a few hundred thousand to over a million dong, users can purchase compact and portable dehumidifiers like Dehumidifier and Tiross. Premium options include products from Edison, FujiE, Daiwa, Coway, Electrolux, priced from a few million to nearly ten million dong.
Domestic dehumidifiers originating from Japan, bearing brands such as Sharp, Mitsubishi, Panasonic, are priced between 2 - 3 million dong to nearly ten million dong, depending on capacity and whether the unit is old or new. Energy efficiency, high durability, and a variety of accompanying features characterize this category of appliances.
