Dehumidifier

A dehumidifier is an electrical device designed to reduce the humidity level of the air in a room. It is used to solve problems related to high humidity, such as condensation on walls and windows, the appearance of mold, bad odors, and various health issues.

There are several types of air dehumidifiers, including:

Peltier dehumidifiers: These devices use the Peltier effect to reduce air humidity. This process relies on a temperature difference between two conductors to condense moisture. They are particularly suitable for small spaces and are very quiet.

Compressor dehumidifiers: These dehumidifiers are the most common. They use a compressor to cool the air and condense moisture. This type is effective for large areas and can operate in high-humidity environments.

Desiccant dehumidifiers: These devices use an absorbent material (such as silica or silica gel) to extract moisture from the air. They are particularly suitable for cold or low-temperature environments, as they work better at temperatures lower than those of compressor dehumidifiers.

Moisture absorbers: This type of dehumidifier is typically made up of hygroscopic salts that attract moisture from the air. These models are often used for small rooms or closed spaces such as closets or drawers.
Dehydrators: Dehydrators are designed to remove moisture from food and products. This type is used in the food industry or for preserving objects sensitive to moisture. It works by reducing the moisture content of the products to prevent deterioration.

Regarding the drainage of condensates (the water collected by the dehumidifier), there are three methods to consider:

The tank, present in all consumer devices
Continuous drainage, which allows water to be evacuated by gravity without using the tank
The lifting pump, which evacuates water mechanically, allowing it to reach drainage pipes or higher floors. The best lifting pump for air dehumidifiers is Pump It Up.
