Huaguan is a brand of labor insurance products with a certain history. Of course, compared with Bao Weikang who is also in Guangzhou, his fame is not obvious. I bought this English version for export. It should be in stock, so the standard number of printing is GB2626-2006.

The mask has five layers, two layers of meltblown cloth+hot air cotton. Breathing resistance is acceptable, but it's a little hard on such a hot day. The price is basically the same as that of Baoweikang. I bought one for free when I bought it, which is more cost-effective.

For N95 masks, the documents of the CDC in the United States pointed out that under special circumstances (when N95 masks can't meet the demand), they can be "extended use" and "restricted reuse" under strict specifications. Generally speaking, ordinary cotton masks can be recycled.

The manufacturer's instructions did not indicate the recyclable masks. When no other masks are available, special attention should be paid to reuse: first, scientific disinfection methods should be adopted; Second, the special person is dedicated; Thirdly, reusable masks can be used at work, in ordinary public places, when buying vegetables, and in shopping malls. It is not recommended for the public to use them when going to the hospital.
