What's the quality of blue crown technology mask?

Personally, I think the quality of Blue Crown Technology Mask is very good.

High-efficiency medical masks are blue-crowned, hydrophobic and breathable, and have a significant filtering effect on tiny aerosols with viruses or harmful dust, but they cannot effectively filter PM 10 and PM2.5, and the overall filtering effect is good, and the materials used are non-toxic and harmless. The products produced by Languan Technology meet the GB2626—2006 standard, and have passed the European CEEN 149: 2009 industrial dust certification, American FDA certification and Mohsen certification.
