The small dehumidification performance is affected by many factors, such as the environmental humidity, temperature, space size and airflow speed(windows or door closed or not). 2. Keep the rear air inlets and top air outlets free from being blocked when the dehumidifier is working. 3. Operating temperature: The optimum room temperature is 59℉-104℉(15℃-40℃ )and Relative humidity: 80%RH. If the air temperature is ＜59℉ (15 ℃), the effect of dehumidification is not obvious, and it will not work ＜41°F(5℃). 4. Operating humidity: The optimum room humidity is 40%RH-80%RH, temperature ≥ 68℉(20 ℃), relative humidity ≥ 60%RH. If the humidity is ＜60%RH, the dehumidifier usually does not remove 16.6oz (450ml) a day.
