据中国之声《新闻纵横》报道，昨天(15日)北京下小雪了，空气清新了许多，不过，雾霾仍然没有完全散去。最近几天，我国大部分地区遭遇严重污染，北京城区PM2.5值一度爆表逼近1000。空气污染人人叫苦，不过，有一部分人却可以苦中作乐了。

According to the sound of China[News aspect]reports,yesterday(15)Beijing under the snow,A lot of fresh air,but,Fog haze is still not fully dispersed.In recent days,In most regions of China have suffered a serious pollution,The Beijing city PM2.5 value once detonation table approaching 1000.Air pollution everyone complain,but,Some people who can the pleasure of taking pains.

　　受污染影响，昨天多支PM2.5概念股开盘就涨停，口罩、空气净化器的销量直线上升，甚至连环保部都加入了采购净化器的大军。有人感慨，雾霾天气已经够闹心了，买空气净化器"排排毒"吧，竟然又被商家五花八门的"高科技宣传攻势"弄了个一头雾水。

Contaminated influence,Yesterday a PM2.5 concept stock open quotation harden,mask/Air purifier sales in a straight line,Even LianHuanBao department joined the army of purchasing purifier.Some regrets,Fog haze weather has enough the could,Buy air purifier"Row row poison"it,Actually, by the businessman omnifarious"High-tech propaganda"Make a confused.

　　空气净化器真的能过滤污染物么？开机器和开窗户，到底哪个更健康？

Air purifier can really filter pollutants yao?Open the machine and open the window,Exactly which is more healthy?

　　日前，中国政府采购网上发布的一条竞价公告引发网友热议。环境保护部机关服务中心，要公开招标购买一台空气净化器。虽然环保部相关人员回应说：这台净化器是专门用于环保部档案室，为了档案防尘而专门配置的，与近日的北京空气质量无关。不过，市面上各大卖场的家用空气净化器，早已开始热卖。在济南泉城路一家大型家电卖场，记者就遇到了前来为家人选购空气净化器的市民姜先生。

a,The Chinese government purchase online publication of a bidding announcement cause net friend of hot debate.The environmental protection department authority service center,To public bidding to buy an air purifier.Although she related personnel response said:This machine is specially used for filter she archives,In order to file dust and special configuration,And the air quality in Beijing has nothing to do.but,The big box on the market of household air purifier,Had begun to hot.In jinan QuanChengLu a large home appliance sells,Reporters were met for the family to choose and buy air purifier citizens Mr Ginger.

　　姜先生：这两天主要也是看微博上济南这个PM2.5"爆表"，从外边走路的时候也是发现有味，雾蒙蒙的，感觉嗓子喉咙也不舒服，回到家之后家里有小孩，也不敢开窗子了，家里的空气老是那么闷着也不舒服嘛，所以过来买个空气净化器。

Ginger Sir:This two days is primarily see micro blog jinan this PM2.5"Detonation table",From the outside walk is also found that pleasure,foggy,My throat is uncomfortable feeling,Home after home have children,Can't open the window,The air is always so boring at home is uncomfortable!,So come to buy an air purifier.

　　经过一番精挑细选，姜先生选择了一台主要针对清除Pm2.5和甲醛等有害物质的空气净化器，价格在两千多元。

After some fine selected,Mr Chang chose a is aimed at clearing Pm2.5 and harmful material such as formaldehyde air purifier,The price is in two thousand multivariate.

　　姜先生：这一款主要是看重去除Pm2.5功能，我比较了一下，因为空气净化器的价格也是非常多，有一千多两千多，也有五千多六千多的，不一样，我觉得适合家庭用的买个两三千块钱的，平时放客厅，睡觉的时候放卧室。

Ginger Sir:This one is mainly regard to remove Pm2.5 function,I compare it,Because the price of air purifier is also very much,There are more than one thousand more than two thousand,Also has more than five thousand more than six thousand,different,I think that is suitable for family use buy a 23000 dollars,Usually put the sitting room,Sleeping of time put the bedroom.

　　电器卖场经理赵靖赢告诉记者，往年顾客购买空气净化器多为新房装修之后用来清除甲醛，但是随着楼市调控、住宅销售量下降，这一类顾客今年明显减少，也使空气净化器销售一度陷入冷清。好不容易逮到了"雾霾天气"这根救命稻草，商家都在着力推广产品清除PM2.5的功能。

Electric appliance store manager ZhaoJingYing told reporters,Ever more customers to buy air purifier for bridal chamber decorates later used to remove formaldehyde,But as the market regulation/Residential sales are down,This kind of customer significantly reduce this year,Also make the air purifier sales once in cold and cheerless.Very not easy to catch"Fog haze weather"This life-saving straw,Businessmen are focus on the promotion of products clear PM2.5 function.

　　销售人员：咱们这个第一层可以吸20微米的微尘，第二层就是活性炭除烟味的，第三层滤芯是除0.3微米的灰尘，所以这个2.5更没有问题了。

Sales staff:Let's the first layer can absorb and micron dust,The second is activated carbon in addition to smoke,The third element is in addition to 0.3 micron dust,So the 2.5 more have no questions.

　　销售人员：去甲醛，去苯，去PM2.5。

Sales staff:To formaldehyde,To benzene,To PM2.5.

　　记者：它PM2.5去除率能达到多少？

reporter:It PM2.5 removal rate can achieve much?

　　销售人员：大于99%，他们这个没有很低档的，销量比较大的就是三千块钱、四千块钱左右。

Sales staff:More than 99%,This is not cheap,Larger sales is three thousand dollars/Four thousand yuan.

　　按照销售人员的说法，能够清除PM2.5的空气净化器都是高档货，这些动辄上千的空气净化器真的能实现他们口中的神效吗？吉林省社科院研究员李晓群持否定态度。

According to the sales staff said,Can remove PM2.5 air purifier is high-grade goods,These frequently thousands of air purifier can really realize their special mouth?Jilin academy of LiXiaoQun researchers a negative attitude.

　　李晓群：现有的空气净化器基本上对PM2.5不起作用，真正有效的只有极高级的。即使真能过滤掉的话只是小范围内的，整个屋子过滤不掉，不能听销售员说的，销售员有的时候为了把东西销出去夸大其词。

LiXiaoQun:The existing air purifier basically to PM2.5 doesn't work,A truly effective only very advanced.Even if really can filter out words only in a small area,The whole house filter does not fall,Cannot hear salesman said,Salesman sometimes in order to put the things pin out exaggerated.

　　理论上讲，目前市面上的空气净化产品基本可分为两大类，一类靠的是各种各样的吸附材料，比如活性炭、光触媒吸收有害物质。另一类用的是等离子放电技术，产生臭氧，分解空气中的污染物。专家表示，臭氧本身就是一种污染物，而吸附材料的原理和饮用水的净化器一样，必须经常换吸附材料，否则还会作为一种污染源把有害物再次释放出来。河北省疾病控制中心病毒防治所副所长刘京生认为，单纯为了雾霾天气而购买净化器的消费者，与其说是在买健康不如说买的是放心。实际上，除了极端的雾霾天气，开窗通风仍然比开机器更有效。

In theory,In the present market condition of air to purify a product basic can be divided into two categories,A kind of by all kinds of adsorption material,Such as activated carbon/Smooth accelerant absorption of harmful substances.Another kind is plasma discharge technology,Produce ozone,Decomposition of air pollutants.Experts say,Ozone is itself a kind of pollutants,And adsorption material principle and drinking water as the purifier,Must often in adsorption material,Or will the pests as a kind of pollution released again.The centers for disease control in hebei province virus dispensary deputy director liu jingsheng think,Simple to fog haze weather and buy purifier consumers,Is not so much in buy health as buy is assured.In fact,In addition to extreme fog haze weather,Open a window ventilated still more effective than machines.

　　刘京生：对这个雾霾天气，实际上没多大的意义，大概就是个心理作用。如果咱们预防呼吸道感染，室内要每天在适当的时间里通一通风，最好的时间段应该是在上午10点左右和下午3点左右，这两个时间段大家可以开窗通风20分钟左右，这样就可以了。不开窗户，指望着空气净化器把你的家里面空气净化特别新鲜，它也只能净化，也不能保证无菌、没有病毒啊，它起不到这个作用。咱们老百姓因为这次的雾霾天气就去买空气净化器，那没有必要。

Liu jingsheng:For the fog haze weather,In fact not much meaning,It is a psychological effect.If we prevent respiratory infections,Indoor to every day in the appropriate time pass a ventilation,The best time should be at around ten o 'clock in the morning and afternoon at 3 o 'clock,The two time you can open a window ventilated twenty minutes,This is ok.Don't open the window,Hope the air purifier to your house inside air purification special fresh,It also can purify,Also can't guarantee sterile/No virus!,It is less than the role.Let's common people because of the fog haze weather to buy air purifier,That there is no need to.

　　其实听了专家的解读可能咱们很多人心里都有一个底了，就是买了空气净化器大多数还是买一个心里安慰，所以说咱们还是应该多听听专家的意见，用科学的方法来抵制雾霾的天气。(记者舒晶晶 实习记者张闻)

Actually after listening to the expert's reading may let's a lot of people may have a bottom,Is buying the air purifier most or buy a heart comfort,So we should listen to the opinions of the experts,Use the method of science to resist fog haze weather.(ShuJingJing reporter intern reporter zhang wen)
