同问，这种的。Procedure ear loop face mask for protection from fluids and particles generated during medical procedures outside of the operating room, including wound care, line changes, dental work and more.
wiki: A surgical mask, also known as a procedure mask or medical mask[1], is intended to be worn by health professionals during surgery and during nursing to catch the bacteria shed in liquid droplets and aerosols from the wearer's mouth and nose. They are not designed to protect the wearer from inhaling airborne bacteria or virus particles and are less effective than respirators, such as N95 or FFP masks, which provide better protection due to their material, shape and tight seal.
非常值得啊
现在国内老百姓啥口罩都买不到 一般的医用口罩就很好了
N95这里也买不到了 我们从美国寄回去家人的大都是一般的医用口罩吧
好点的是level3 很多人买的连level3的都不是
这个怎么买？我点进去但是没有价钱。是不是一定要有portal 才能买？
我在别的网站上买的，75 刀一盒，40 个口罩。
