All of Yidunpu's products are imported from the United States, and have passed China's 3C certification and various tests, and the quality is guaranteed. Among all kinds of products, electric heaters are the most successful products of Yidupu in the past 10 years, and are well-known in the United States and Japan, of which the annual sales in the United States are more than 1 million units. In 2011, Yidupu officially entered the Chinese market.
 
At present, there are four models of EDUNPU warm boxes: GEN3E, GEN3C, GEN4 and GEN5, which are completely different from traditional electric heaters in appearance, with a square design silhouette and a deep black tone, which is very similar to the subwoofer in a professional surround home theater. Ordinary electric heaters have always had problems such as unsafe, small heating range, dryness, etc., but solving these problems is precisely the strength of Yidunpu warm box, which applies the principle of convection heating to make the overall temperature of the room faster and more uniform, and at the same time, it will not take away a large amount of moisture and oxygen in the air when heating, which can well maintain the humidity of the room, and the comfort is much higher than that of ordinary electric heater products. Moreover, the temperature of the shell part of the warm box is basically lower than 35 degrees when it is in operation, which is not hot to the touch, and the safety factor is extremely high. If users need to use electric heaters in bathrooms and toilets, it is recommended to buy GEN3E warm boxes with a domestic price of 1188 yuan, this model does not have an LCD screen, has good moisture resistance, and GEN3C, GEN4 and GEN5 and other models are equipped with LCD screens, which will not be used in case of moisture.
 
If the user has children at home and has higher requirements for safety performance, it is recommended to buy the GEN3C model, which is priced at 1488 yuan in China. This product can be set to turn on and off the 8-hour timer, and it is designed with a child lock to prevent children from changing settings naughtily. Both the GEN3E and GEN3C have a dust-proof primary filter that can effectively filter > 0.28mm of fiber particulate matter, but the user needs to clean the dust filter once a week during normal use, which is more troublesome.
 
Compared with the previous two generations, the rated power of GEN4 has been increased to 1800W, the heating capacity is better, and the negative ion purification function is added, and the three-layer filter screen design is adopted, after the primary filter filters out 0.28mm fiber particulate matter, the HEPA filter further effectively removes PM2.5, second-hand smoke, oil smoke and other particles, and the third layer of activated carbon can adsorb benzene, formaldehyde and other harmful gases. Having such a product allows you to turn on one less air purifier in the winter, which is very practical for homes with improved air quality. It is worth noting that the filter of GEN4 can only be replaced, not cleaned, it is recommended to replace the filter once a year, the filter is priced at 299 yuan on mainstream e-commerce platforms, and the price of GEN4 is 1688 yuan.
 
GEN5 has not only been improved in terms of heat, safety, intelligence and appearance, but also extended its timed on/off time to 24 hours, with prices ranging from 2288~2688 yuan.
