Respiratory Filters come in a variety of ratings that relate to how the respirator performs (how much it filters) and what environment type it is designed to be used in. When choosing a respirator it's important to understand that as the letter rating and number rating increase, breathing fatigue will increase. While you certainly don't want to choose a rating that is too low, you don't necessarily always want to pick a P100 filter for every application - particularly if you're just looking for a simple dust mask to do home improvement work. Typically, an end user will find an N95 respirator cooler, and easier to breath through than a P99 or P95 dust mask.
Respirator Rating Letter Class N - Not oil resistant R - Resistant to oil P - Oil Proof
Respirator Rating Number Class 95 - Removes 95% of all particles that are at least 0.3 microns in diameter 99 - Removes 99% of particles that are at least 0.3 microns in diameter 100 - Removes 99.97% of all particles that are 0.3 microns in diameter or larger. HE or HEPA quality filter.
就这么多
有人穿的比这个多的吗？
进门前在外面先脱外面的，进了屋再脱里面的，喷洒消毒水也是在屋外
我也要上班, 还是办公室在公立医院旁的那种. 我是穿一套贴身运动装, 外面再一套西裤、外衣、衬衫, 戴眼镜、口罩、手套上班, 下班上车前, 脱掉外面的一套和手套再上车, 回到家洗手除口罩, 挂到太阳房, 呆几天在循环再用, 然后赶紧脱衣服扔洗衣机洗, 接着赶紧洗脸、酒精片消毒耳朵, 洗头, 洗澡.
你的方法很好，搁置几天循环再用
不喷洒消毒水的情况下，至少应该搁置几天为妥？
有太阳晒的话, 晒个大半天病毒怎么都杀死了吧, 不过保险点, 我是四五个轮着用的.
to take a leak简单，打开前窗把两根手指伸进去就行了
别的就有点儿麻烦了，要先把外衣脱掉，解开一根背带，还要打开侧面的纽扣
异曲同工，多出汗多喝水有利于清除杂质
多管齐下，誓与病毒争存亡，不是它死就是我活，向你学习，打算七套轮着用
人生如戏，戏如人生，每一个人都在生活中扮演着各自的角色，尽力演好自己的角色，自己就是最佳主角。
P95的功效与N95一样，只是多了一点耐油性，尤其适合于加油站工人，周末去加汽油，戴P95最合适
其实口罩并不能直接过滤掉病毒，就好比后院的篱笆墙阻挡不了小老鼠的通行一样
口罩的实用效能主要有两个：
1、过滤掉随风漂流的携带病毒的尘粒，或咳嗽打喷嚏的吐沫液滴
2、避免口或鼻直接接触到沾有病毒的物体，比如，手
