Normally, for requirement of high relative humidity from 45% ~ 60% and dew point temperature of the environment should be handled > 10 ° C, the device should be used for dehumidifying with the form of condensation described by the principle of dehumidified diagram as follows:

Air is drawn into the dehumidifier => Gas in blocks of dehumidifiers will freeze the moisture in the air into the liquid water => The water will flow into the container => Dry air will be blown out through the ventilating system.

Through a recent experiment has showed that: All kinds of dehumidifiers which are put into trial operation do not lead to the same result. There are some cheap dehumidifier brands like Fujie, Edison, Aikeno … are capable of dehumidifying very well; some good brands of dehumidifiers, more expensive, more energy so that the power consumption is higher.

  • – Quality of the sieve and filter are not high.

  • – No brand names or unclear logo.
  • – No warranty card or warranty information on the card is very vague.
