Dehumidification mode is a setting on many mini-splits that removes excess moisture from the air without significantly lowering the temperature. This feature is standard on the Cooper & Hunter Single Zone Astoria. It is particularly useful in humid climates where the air feels "sticky." You can find units with advanced humidity control in our Wall Mounts 2 Zones category. Reducing humidity helps prevent mold growth and improves overall comfort. It allows the user to feel cooler at a higher temperature setting.
