First, distinguish from each series. Divided into cloud Rubik's cube, wind Rubik's cube and star Rubik's cube series products. The first two letters of each series model are different. For example, EM is the European top range hood of Cloud Cube, JQ is the near-suction range hood of Wind Cube, and Z 1 is the Star Cube. The design of each series of products is different, but the functions are actually similar. Just choose the right range hood according to the decoration style.
