上個月,廣東省、北京市以及上海市據報道正在生產一種新型口罩,這款口罩使用的材料不是傳統的熔噴無紡布,而是用納米材料薄膜材料來過濾細菌、病毒以及其他病原菌。
Last month, companies in Guangdong province, Beijing and Shanghai reported producing a new type of face mask that uses a nanomaterial membrane1, rather than the typical melt-blown fabric2, to filter bacteria, viruses and other pathogens, according to local health and medical products authorities.
 
The new masks are on par3 with N95 standards, meaning they filter particles of all sizes with at least 95 percent efficiency.
 
The masks are also comfortable, easy to breathe through and can be reused up to 20 times depending on the user's setting and wear time, the authorities said.
 
The retail4 price for the masks created by companies from Shanghai will be around 15 to 20 yuan ($2.14 to $2.85) each.
 
The prices for the ones made by Beijing and Guangdong companies are still unknown because those companies just recently began production.
