Maintain appropriate humidity. , pharmaceuticals, etc. Manufactured, produced and stored within the required humidity range.

How a home dehumidifier work

The principle of a home dehumidifier is to absorb the humid air in the room, condense the moisture in the air into water droplets through the heat exchange system, and then discharge the treated dry air out of the machine to reduce the relative humidity through air circulation.


Main uses of household dehumidifiers


Especially in coastal areas and during the southern rainy season, using a dehumidifier can effectively reduce indoor humidity and prevent damp and moldy conditions, and is particularly effective in wet areas such as bathrooms and kitchens, as well as rooms close to bathrooms and heating.

Adsorption dehumidifierAdsorb water vapor in the air through adsorbents (such as silica gel, activated carbon, etc.) to achieve the purpose of dehumidification.

Different types of dehumidifiers have different dehumidification effects, energy consumption, and maintenance, so when purchasing, you need to choose the appropriate type according to your needs.

Consider the dehumidification capabilities of dehumidifier

Dehumidification capacity is an important indicator of dehumidifier performance and is usually measured in “liters per day” (L/D). When shopping, according to their own home area and humidity requirements to choose the right dehumidification capacity. Generally speaking, the family area of 30-50 square meters of home, a dehumidifier capacity of 20-30 liters/day can meet the demand.

Noise level

Concerned about dehumidifier tank capacity

The water tank capacity of a dehumidifier is usually between 2L and 8L. The specific choice of water tank with a large capacity needs to be determined based on the use environment and needs. If the use environment is mainly in the bedroom and living room, it is recommended to have at least a 4L water tank model; if it is a space such as a gym, wine cellar, piano room, or computer room, it is best to choose a large-capacity water tank model of about 8L. If it is used in a bathroom or a space with a floor drain, there is no need to consider the size of the water tank since modern dehumidifiers have a bottom drainage function.

Look at the compressor: it is recommended to choose a big brand

The heart of a dehumidifier is the compressor, but the brand of compressor used varies widely depending on the model. Among them, Meiji, Linda, Panasonic, etc. are good brands!

Anti-spill function
