A desiccant dehumidifier operates on a totally different principle to a refrigerant type. The main benefit of a desiccant dehumidifier is that it performs exceptionally well when used in cooler climates, or when a low dew point is required. As there is no actual water produced during the process, these units can work effectively at sub-zero temperatures.

Due to COVID-19 pandemic, the global Desiccant Dehumidifier market size is estimated to be worth US$ 568.1 million in 2021 and is forecast to a readjusted size of USD 697.1 million by 2028 with a CAGR of 3.
