手上也就25+3的N95
还有以前凑单买的一些手术口罩。

N95这种有反复用会有效果吗？ 回家后用酒精喷瓶喷一圈放好。。

4小时就得换，都是一次性的。我搞了个3M 7502+2907，还没送到

过年别出去就行了，一天出门一次，能用一个月

一次性就夸张了，其实灭菌处理后可以反复使用的。

不去人流密集场所，我觉得普通医用的也够了。

不知道紫外线灯可以消毒n95不

没多少人是持续4小时用的，多在家，少出门，差不多的

普通医用的也买不到了。。要不就是高价。。


现在这个N95霍尼韦尔的平均是3块多一个

用完之后丢在紫外线灯下半小时。或者微波炉30秒。。

哪里有买？为啥我淘宝搜都是30多的

美国疾病控制中心的说法是，N95一般规范是用8小时

Respirator Extended Use Recommendations
Extended use is favored over reuse because it is expected to involve less touching of the respirator and therefore less risk of contact transmission. Please see the section on Risks of Extended Use and Reuse of Respirators for more information about contact transmission and other risks involved in these practices.

A key consideration for safe extended use is that the respirator must maintain its fit and function. Workers in other industries routinely use N95 respirators for several hours uninterrupted. Experience in these settings indicates that respirators can function within their design specifications for 8 hours of continuous or intermittent use. Some research studies (14, 15) have recruited healthcare workers as test subjects and many of those subjects have successfully worn an N95 respirator at work for several hours before they needed to remove them. Thus, the maximum length of continuous use in non-dusty healthcare workplaces is typically dictated by hygienic concerns (e.g., the respirator was discarded because it became contaminated) or practical considerations (e.g., need to use the restroom, meal breaks, etc.), rather than a pre-determined number of hours.

出门人多密闭空间用下，这样一个口罩能用好几天

高温干燥紫外线消毒，理论上可以，但无纺布肯定会有损耗的。

CDC在SARS时期建议，如果口罩得不到充足供应，在没有明显污染或者损坏的情况下，可以考虑继续使用。
If a sufficient supply of respirators is not available, healthcare facilities may consider reuse as long as the device has not been obviously soiled or damaged (e.g., creased or torn). Data on reuse of respirators for SARS are not available. Reuse may increase the potential for contamination; however, this risk must be balanced against the need to fully provide respiratory protection for healthcare personnel.

If N-95 disposable respirators are reused for contact with SARS patients, implement a procedure for safer reuse to prevent contamination through contact with infectious droplets on the outside of the respirator.

你是指哪个？

N95的话我是京东买的。京东自营。买了25个的一套3个的一套。

肯定是一次性的，你多次使用那就和中药没区别了

早上看外国文章说N95长时间使用对肺部有影响，联想到薯片说身体不适，应该是真的

不要有侥幸，都是一次性的

那你记得扔衣服

没听说过要扔衣服，又不是核辐射

N95对肺部影响和病毒无关的，你要是害怕把口罩上的病毒带回家，那就是连衣服也得扔，因为如果口罩上有，那衣服上肯定也有。

说实际的，这点口罩后面得顶上两个月，你看看你有多少N95够一次性用吧。

不要放微波炉，会烧掉、别问我怎么知道的，紫外线就好了，实不行扔高压锅煮个十几分钟晾干继续用

买不到，着急
