The positioning of the LOGO on the mask is important as it should be prominently displayed. To achieve this, the LOGO is typically placed facing outward and positioned in the upper right corner when looking at the mask. It is essential to ensure that the logo is correctly written and positioned to enhance brand visibility and recognition.
There is no doubt that the metal strip should be on the top of the face mask. Depending on the number of layers of the metal strip, the single layer needs to face outward while the double layer needs to face inward. It's easy to identify the metal strip when looking at this side of the single layer, and the few layers of the metal strip can also cause bulges. However, the description only mentions the bulge, which might not be intuitive or rigorous enough. The wearing experience confirms that the metal strip position is correct. It's essential not to judge the mask orientation by looking at the thread or direction of the fold since every family may use a different method.
To prevent the public from purchasing fake masks, it's essential to know how to distinguish between authentic and counterfeit products. Checking the authenticity of masks can be done through various channels, including checking the official website of the State Drug Administration. By clicking on the "Medical Devices" and "Domestic Devices" options, individuals can search for the company's name and retrieve information such as the approval number and other detailed information. This approach can help people avoid purchasing counterfeit masks and ensure that they are using effective products to protect themselves and others from COVID-19.
