Dehumidifiers are electrical appliances used to reduce environmental humidity, widely applicable in humid environments such as homes, warehouses, and basements. Their core components include a compressor, condenser, and evaporator, which utilize the condensation principle to extract and expel moisture from the air, keeping it dry. The products come in various types, including small household models, large industrial machines, and portable devices, some of which also have air purification functions. They are suitable for use during the rainy season, in coastal areas, or in places that require moisture prevention, effectively preventing mold growth, protecting furniture and electronic products, and enhancing the comfort of living and working environments. When choosing a dehumidifier, factors such as dehumidification capacity, energy efficiency, and noise levels should be considered.
