The predecessor of Maidilon is Ningbo Dongda Air Conditioning Equipment Co., Ltd., although it claims to be "German Maidillon", but in fact, it has little to do with the "Made in Germany" in the impression of consumers, Maidilon currently has three sheet metal production lines and three new fan assembly lines, the overall strength of the enterprise is average, and the products are mainly cost-effective to occupy the market.
 
However, the comprehensive performance of the central fresh air system of Maidilon is still okay, and the product series is also very rich, all of which are full heat exchanger types, users can buy suitable products according to different needs, and the overall price is much lower than that of first-line brands, such as CHRV-3.5Q-DC under the low-noise series, with an air volume of 350m³/h and a price of less than 10,000 yuan.
 
The filtration system of Maidilon adopts pure physical technology, composed of G4 primary H11 HEPA filter, and the performance of haze removal is decent, it is recommended that users living in serious haze areas can choose a purification box, and in terms of full heat exchange efficiency, Maidilon still has a lot of gaps with first-line brands, and the energy exchange rate barely exceeds the minimum limit of the national standard, and the reliability of the product also needs to be improved.
