前言:
PM2.5测试表是抗霾必备工具。新风系统是抗霾唯一终极解决方案。
能装中央新风系统的尽量装中央新风系统,不能装中央新风系统,也要至少装几个壁挂式新风。
什么新风系统都不能装的情况下,才考虑空气净化器。

IV、相关知识介绍:
一、PM(Particulate Matter,颗粒物,空气中固体颗粒或液滴的总称的危害性。
PM也称为可入肺颗粒物,直径标准有多种,包括但不仅限于PM10/PM2.5/PM1.0/PM0.5/PM0.3这几种。
PM2.5(每立方米空气中空气动力学当量直径小于或等于2.5微米的颗粒物重量)是目前官方会经常公布监测数据、和PM相关的大气污染指数。
1、科学松鼠会:关于PM2.5的十个问答
2、果壳网:是的,PM2.5能致命
3、钟南山:人体能对PM2.5产生抗体说法毫无依据。在广州,不少人到了四五十岁,肺变成黑色。
4、8岁女孩吸入雾霾患肺癌:大气污染成第一致癌物
5、柴静:苍穹之下(原始视频已被屏蔽)

二、现有解决途径:
室外:戴专用口罩。钟南山:防PM2.5需用N95型口罩
防PM2.5口罩哪家强?反正不是N95
室内:
1、带净化空气功能的空调:
净化能力极其有限,基本可以忽略。
2、空气净化器:
1)常规情况下需在密闭空间中(关闭所有门窗)使用,对降低有限的几种空气成分比如甲醛和PM2.5的浓度,有较好的效果。
(空气净化器的说明书上各项性能参数均为密闭环境下测试得出。)
在密闭空间使用的关键缺陷是,二氧化碳、油漆的各种味道、特别是人的体味(人味),都和室外对流缓慢,基本只能通过窗户缝对流,浓度会逐渐积聚的很高。
这些成分浓度过高对人的健康是有不良影响的。
2)如若开窗使用,室内空气和室外形成了良好对流,PM颗粒物的浓度也会基本一致,空气净化器就完全是做无用功了。
所以结论是,空气净化器独立使用,不能较好的解决室内空气净化问题。
3、新风系统:
新风系统源源不断的把室外空气过滤之后,送入室内,并把室内污浊的空气抽到室外,比较完美的达到了了换气+过滤的效果。
医院手术室和各种博物馆,都已经使用了多年的新风系统。

三、结论汇总:
1、室外:带专用口罩;
2、室内:新风系统主力+空气净化器补充
所以,目前解决室内空气PM颗粒物污染问题较好的办法,是装新风系统(365*24小时关窗关门)+空气净化器
