The capacity of a dehumidifier refers to the maximum amount of moisture that can remove from the air within 24 hours. This capacity is based on optimum operating conditions. For example, our Compact Domestic Dehumidifier has a capacity of 19 Litres per day. This is based on a Relative Humidity of 90% at 32.2 degrees Celsius. A typical performance in conditions of 60% Relative Humidity at 26.7 degrees Celsius is 9 Litres per day.

A damper room with a warmer temperature will result in faster water extraction. In a cooler space, or when a dehumidifier has been running for some time (and therefore removed the initial humidity) the water extraction rate will decrease.
