Philips has maintained a stable market share in the domestic home appliance market, subdivided into the field of dehumidifiers, Philips has not invested too many resources, there are only 3 models on the market, but it still maintains a high level in industrial design.
 
The dehumidification capacity of the compression dehumidifier is greatly affected by the environment, the higher the temperature (within the working range) and humidity, the better the dehumidification effect, so the manufacturer's nominal dehumidification capacity should indicate the temperature and humidity conditions. At present, domestic dehumidifiers generally use the daily dehumidification capacity under the condition of temperature of 30 °C and relative humidity of 80% as the nominal value. However, due to the lack of strict specifications in national standards, some manufacturers have set the temperature and humidity to be too high and "falsely marked" the dehumidification capacity.
 
Philips' three dehumidifiers DE4202/00, DE4201/00 and DE5206/00 have a nominal dehumidification capacity of 32°C80%RH/32°C90%RH/35°C90%RH under three different environmental conditions, respectively.
 
The nominal dehumidification capacity of DE4202 is 19L, and in the test conducted by the Shanghai Consumer Council, the measured dehumidification capacity is equivalent to that of the same specification products in the market, and it can be purchased. However, the test conditions of DE4201 and DE5206 are far from the industry standard, and there is no specific conversion relationship between the two, so they are not recommended.
