这篇NYT的文章提到了美国本土的ArmBrust USA发现amazon上卖的KN95全部不达标。虽然反馈但是根本没法禁止。于是他们自己也做KN95,说能保证质量(网站附上了检测标准)。而且KN95不需要像N95经过FDA严格的验证(很花钱和精力),节省了一定成本。不过价格还是比Amazon上来自中国的KN95贵。 Omicron海啸来临之际,cloth mask和外科口罩基本不顶用了。最好是N95级别的(比如KN95, KN94和FFP2)。 想了一下还是支持一下美国企业吧。刚刚下单了ArmBrust USA的3盒kid专用KN95口罩以及2个mask brace。运到咱们州没有税,用上了一个30% off coupon(下面提到了),最后大概每个KN95口罩的价格是$1.75(before 10% portal cashback)。小娃戴着印了made in USA的口罩也许比较拉风和自豪? https://www.armbrustusa.com/collections/usa-made-n95-masks-respirators/products/armbrust-usa-made-kids-kn95-mask 可以通过很多cashback网站有10% cashback(比如Topcashback和MrRebate)。 MrRebate还有一个30% off coupon (Stop-Delta)可以兼容使用,12月31日过期。这个code不保证在topcashback网站能兼容10% cashback。 如果没有MrRebate帐号,可以考虑使用我的referral :) http://www.MrRebates.com?refid=953030

亚麻就有,但是注意seller要是Dr.puri official
这种Dr Puri在哪里可以买到? 求link, thanks
搜到一些idea...
挂在脖子上又怕擦来擦去反而弄脏了😅
🛋️ 沙发板凳
现在最烦的是要不要带小孩去打疫苗,纽约市感觉没有恢复网课的意思
我天happy masks也太贵太难买了。mm最早是怎么发现这个牌子的?
为什么不打呢?纽约数据显示疫苗对小孩子是有保护作用的:https://abc7.com/covid-in-kids-vaccine-omicron-variant-children-with/11393077/ 新变种感染的大部分是没打疫苗的小孩。
当然这个是小样本。以后样本大了,数据更可靠。但我更希望多一点小孩打疫苗,少一点感染的大样本。
防护效果好和戴着舒服是矛盾的,就一般医用口罩就好了,升级了大人还能受得了孩子哪受得了。芬兰那里好像六七岁都不要戴口罩的,老师戴,小朋友戴其实还真是对他们各种发展有限制的
我也在纠结。效果好的怕孩子难受,戴不住。那就还不如一层普通医用的。
我家离学校还挺近,不知道可不可以白天去一两趟学校帮小孩戴戴口罩。在家网课一年多了,真是快疯掉了。

种草了:)
duck是bluna吗?
是的
不知道dr puri 比医用口罩如何? 前者不知道材料比医用的怎么样?但是肯定更fit
确实是有顾虑 12-17岁接种率大概超一半,住院的1/3就是打过疫苗的了 5-11接种率不到20%,样本小
材料比一般的surgical也好一些
最早是play date的妈妈推荐的。当时没有缺货,但是太贵了所以就买了几个试试,用过觉得对小娃们真的是太友好了,设计也很棒。
在这理看到5-11的by dec初,不过好像是一针的。vt贡献了一半啊。 https://www.kff.org/coronavirus-covid-19/issue-brief/an-update-on-vaccine-roll-out-for-5-11-year-olds-in-the-u-s/
你是对的,曼哈顿的确是99%,有这么高?
纽约地区华人接种率整个都非常高
以前都是儿童版的byd,还有costco的那款儿童口罩。
的确是贵,而且我排了2个月才排到,然后发现它们是弯弯产的,自称弯弯是一个口罩技术强国
没人用以色列的那种 sonovia 吗?据说是黑科技口罩里面处理过可以杀病毒。好多媒体报道过。
墙裂推荐 Lutema ASTM level 3. 这个口罩产自 San Diego. 4-layer. 我们用着很满意。 https://lutema.com/collections/made-in-usa-masks/products/made-in-usa-astm-level-3-breathable-face-masks-for-kids-50-pack

我早就排到了。。。然后被价格劝退了,实在也太贵了
要买 NIOSH-Approved的
问一下楼主在哪里看到Dr Puri只是防粉尘的? CDC网站上的测评好像还不错啊。https://www.cdc.gov/niosh/npptl/respirators/testing/results/MTT-2020-252.4_International_KMCorp_DrPuriKF94_TestReport_Redacted-508.pdf
不推荐 排队排了整整3个月才买到。 小孩的size偏小。 太脆弱了。 不能揉搓 。 清洗只能泡 了然后清干净。 毕竟是布的, 感觉有很多机会会被揉搓到。 如果揉搓就会导致防护性能下降, 这个估计很快就远达不到开始号称的那么高的防护程度了
贵是一回事,怕size不合适,这small给多大孩子的?
这个不错,但我家初中的嫌小
看看aaron collins的测量就发现这些filtration一般
平时带带可以,爆发期可能不够
正在找小孩口罩,谢谢推荐
请问如何请假?有什么好excuse?怕学校直接劝退…
你到Amazon网站看包装照片,盒子上写的….
直接说病了能行吗?或者因为家里有high risk大人?我家真是第二种情况,就怕孩子带病毒回家。
防粉尘没问题的,可以防新冠。医生用防溅的是因为他们做手术可以溅到体液
这种kf94 (比如bluna和dr puri) 以及成人用的n95 看着贵,实际上可以用不止一次的。用完了把它晾半天,然后用纸包起来放置在干燥处10天再带一次,这样一共可以带几次。
实际上最先坏掉的是鼻子wire和绑带,导致不能密封了,口罩体本身可以up to 40h use.

看了一下网站, 过滤效率99.9%又完全不影响呼吸和舒适度,让人生疑
起个名儿
我疫情期间也是这么用N95口罩的。
我给孩子是KF94,因为孩子受不了太紧,3D造型方便他说话 大人去人少得地方是一次性医用口罩,人多的就是KN95 KN95时间长了有点勒耳朵,孩子估计也受不了
原来可以这么用啊, 我女儿除了Dr. Puri,别的牌子都不愿意戴。 因为每天去学校,所以几乎一天一换。 以后可以用你说的方法,可算省钱了。太感谢MM了。
看到滤过99.9% 细菌和病毒,还不妨碍呼吸,就知道是吹牛了,还没有FDA批文!!!!!
哈哈,不客气,可以循环个3次。每次带上记得检查一下鼻子不漏气。 带和摘得时候轻柔点
而且医用口罩里面有致癌物,娃长期一天到晚戴着也担心,真是矛盾,唉
Washable的,可以重复使用啊?
这款耳朵非常容易滑下来
看了一下可以洗50次啊?平均下来也不贵
普通医用口罩也有不少chemical, 还致癌。N95我猜更多?Happy Masks我看了一下是washable的,应该好一些
你在开玩笑吧mm?😂
我也是看了这个人的视频,开学前买够了一年量的KF94。每天一换,虽然贵,但是花钱买个安心。
请问是dr puri的吗
https://store.savewo.com/products/3dkidsl2
我也发现这个救世口罩测评很好,有人买过吗?
不知道是啥材料,为什么会比其它得透气呢?
是呀,我同意。那个过滤效率我从来都不信在现实中可以达到的,因为小朋友们不会戴得严丝合缝的。 我觉得这个口罩材质是真不错,然后就是小朋友戴起来舒适。 另外不推荐买成人版的,我买了,但是觉得脸部没有小朋友版的贴合
我家带着个好像鼻梁的地方总掉下来,还没有BYD的罩得住,我也犹豫给她带哪种?
它家现在有英文网站了 可以直接订 我还没买过 这一波又严重了 在考虑要不要团购一箱回来
