Like Rinnai, Noble is from Japan, and has more than 60 years of professional manufacturing history in Japan, and is committed to developing high-performance and environmentally friendly products, which led to the recognition of the Japanese government's Ministry of the Environment as "Environmental Choice" in March 2009.
 
Nengsu has a deep R&D strength, and its products maintain a good image in China's kitchen appliance market, but its main products are gas stoves and water heaters, and there is not much focus in the field of range hoods.
 
C1687 is a high-performance side suction product, large air volume and strong suction, no less than the top suction machine A1881, its enclosed motor is made of all copper material, which can effectively prevent water and oil resistance, and the intelligent opening and closing baffle is responsible for preventing the smoke from rising and escaping. The defects of this product are also obvious, the oil separation is low, and the lack of automatic cleaning function will make it more cumbersome to clean.
 
A1881 is priced at 3099 yuan, which is a representative high-end top-suction range hood with energy rate. The full air intake design effectively overcomes the problem of fume escape caused by top suction products. The maximum instantaneous air flow is 20 m³/min, and the oil separation is more complete by increasing the blade area.
