Globally, the brand concentration of dehumidifiers is relatively low, and De'Longhi is one of the brands with the highest coverage. Both evaluation agencies have good reviews, but in the evaluation report released by the Hong Kong Consumer Council in 2018, the measured dehumidification capacity of its DEX16F model under 30°C/80%RH conditions is seriously inconsistent with the nominal amount, with a difference of 34.8%, and the same model is also sold in the mainland, so it is not recommended for consumers to buy.
 
De'Longhi and TCL have established a joint venture company in Zhongshan, Guangdong, specializing in the production of dehumidifiers and mobile air conditioning products, in addition to De'Longhi dehumidifiers from different foundries in Kaiping, Guangdong and Changzhou, Jiangsu. The dehumidification capacity of De'Longhi dehumidifier covers 8.5-40L, but the corresponding environmental test condition is 32°C/80%RH, which is different from the 30°C/80%RH commonly used in the domestic market, and there is a suspicion of "false standard".
 
The DDSE20 is one of De'Longhi's best-selling models, with a dehumidification capacity of 20L, and in the 2017 test conducted by the Shanghai Consumer Protection Committee, the measured dehumidification capacity and dehumidification efficiency are among the best, and the performance can be described as strong, but the noise is below average, and the user experience is somewhat compromised. In addition, the control panel of De'Longhi dehumidifier is also designed in European and American style, there are only icons and diagrams on the buttons, and there is no text description, if it is used by the elderly, it takes a certain amount of time to get used to.
 
DD40P and DD30P have a dehumidification capacity of 40L and 30L respectively, in addition to the standard water tank and external drain pipe drainage, it also supports pump pressure upward drain function, and the drainage height can reach up to 5 meters, which is more convenient when draining continuously. The overall weight is close to 20kg, but fortunately it also comes standard with hidden handles and swivel casters.
