评论说产品已经变了,不是KN95。 https://www.costco.com/fltr95-sealing-face-mask%2c-100-masks.product.100670394.html

I ordered this product on 9/1 due to the comments saying they were labeled KN95 and they were! I was very happy, so I ordered another box on 9/8 for a family member on chemo. They arrived with slightly different packaging and no longer the KN95 designation. They now come stamped with FLTR95. When looking over the product qualification certificates I noticed the following changes in Primary Product Materials: - KN95 labeled: Melt-Blown Polypropylene Filter 42.8%, Hot Air Cotton 28.6%, Polyester Shell 28.6% - FLTR95 labeled: Polyester Shell 50%, Hot Air Cotton 16.7%, Melt-Blown Polypropylene Filter 33.3% There is an obvious change in materials that likely change the mask''s filtering properties. If you''re looking for KN95, this product is NOT for you.

买了100个,质量凑活,比蓝口罩要厚实,ear loop 松,得打个结才能扣住脸。呼吸时有雾气到眼镜。

又查里了一下,盒子外面标签写的是made in China, 是GB2626-2019标准,这个标准不是N95,但是根据OSHA.gov 可以替代N95.
