高科技口罩多少钱？

今天看了下Wired上最受欢迎的22款口罩。前三名分享一下：

第一名,Tom Bihn V4 Cotton Flannel Reusable Face Mask
售价：$16一个
简介：100%纯棉法兰绒口罩，舒适轻巧不过敏，并且有研究表明带有棉纤维质地的棉花是最有助于防止病毒传播的。研究在这里https://t.cn/A6GY71vC 。
应该是进口面料在西雅图缝制，所以也算made in US。黑色蓝色可选。

第二名，Outdoor research face mask kit
售价：$20 三个
简介：别看口罩卖的比第一名便宜，这个口罩是个kit，内部的滤芯每8小时需要替换一次，滤芯大约$1 一个。 过滤技术也有专利，因为是“Outdoor Research”嘛，HeiQhttps://t.cn/A6GY71vN。 多种颜色可选。滤芯只有白色。 可水洗30次。Made in US。

第三名，Sunday Afternoon UVShield Cool Facemask
售价：$12一个
简介：专利材料最多的口罩，包括Coolcore® ，OEKO-TEX® Standard 100 certified exterior fabric; bluesign®。 主打防晒、透气、清爽。可是没有什么信息是关于防病毒的。

当然普通医用口罩也排到了top 10。

小看了街上那些口罩了，原来都是专利产品... ...

Almost lover.
Be a better person for myself!
I’m not just like a 18-year-old girl, being naive and stupid, and I know that the world has changed more complicated.But I still want a simple life for being happy. If everything goes so wired and unexpected, then I’d rather being alone. I would try to look after myself, and I believe that I can do it better.
Stay strong & Stay hopeful. https://t.cn/R2WxdDX

Day3 如何自我介绍[二哈]
I’m new wave ,but I’m old school
My inner child is outward-bound .
I’m hot-wired,heat-seeking warm-hearted cool customer.
Voice-activated and biodegradable.
I interface from a database ,my database is in cyberspace, so I’m interactive ,I’m hyperactive.and from time to time I’m radioactive.
Behind the eight ball,ahead the curve ,riding the wave, dodging the bullet,pushing the envelop.
I’m in the moment ,on the edge , over the top but under radar, a high concept, low profile ,medium range ballistic missionary.
A streetwise smart bomb, a top gun bottom feeder.
