Check product packaging and machine appearance.

1. Check the product packaging: The genuine Boss range hood packaging box should have clear trademarks, manufacturer information, product models, etc., with clear fonts and bright colors. The packaging quality of counterfeit products is poor and the fonts are blurry. The color is dull.

2. Check the appearance of the machine: The authentic Boss range hood air duct cover has an anti-counterfeiting label, but the counterfeit products do not.
