人的一生中，至少有80%以上的时间是在室内环境中度过，然而，室内空气可能存在甲醛这个危害人们健康的杀手。
In human life, at least 80% of the time is spent in the indoor environment, however, there may be formaldehyde in indoor air, which is a killer to people's health.
甲醛到底有多可怕？
How terrible is formaldehyde?
甲醛超标会使人出现头痛、头晕、乏力、恶心、过敏性皮炎等不良症状，甚至会引起鼻咽肿瘤。甲醛已被国际癌症研究机构（IARC）等列为一类致癌物质。
Excessive formaldehyde can cause headache, dizziness, fatigue, nausea, allergic dermatitis and other adverse symptoms, and even lead to nasopharyngeal tumor. Formaldehyde has been listed as a carcinogen by the International Institute for cancer research (IARC).
室内空气中的甲醛主要来自用作室内装饰的人造板材、粘合剂、油漆和涂料等。令人忧心的是，甲醛释放缓慢，潜伏期可长达3-10年，仅仅通风几个月较难根治问题。因此，林林总总的除甲醛方式和产品应景而生、流传甚广。
Formaldehyde in indoor air mainly comes from artificial boards, adhesives, paints and coatings used for interior decoration. Worrying is that formaldehyde release slowly, incubation period can be as long as 3-10 years, only ventilation for several months is difficult to cure the problem. Therefore, formaldehyde and products occasional born, widespread in the numerous.
为更好地进行室内空气净化产品比较试验和指引消费，深圳市消费者委员会联合深圳市品质消费研究院选择在深圳2012年-2015年间新建商品房住宅小区，对深圳市民除甲醛产品使用情况进行现场调查。通过583个有效样本数据，对消费者眼中的除甲醛产品一探究竟。
In order to make a better indoor air purification products test and guide consumption, the Shenzhen Consumer Council with the Shenzhen Institute of quality consumer choice of new commercial housing residential area in Shenzhen during 2012 -2015, the people of Shenzhen in addition to the field investigation of formaldehyde product usage. Through 583 effective sample data, the formaldehyde products in the eyes of consumers are explored.

大家都愿意自己购买甲醛测试器材
Everyone is willing to buy formaldehyde testing equipment
电子检测仪和检测盒自测甲醛方式受欢迎
Electronic testing instrument and test box, self testing formaldehyde is popular
本次调查，近两成的受访者已经进行过甲醛检测，而近七成的受访者表示未来会考虑进行甲醛检测。对于已进行过甲醛检测的受访者，主要采取了以下检测方式：
In this survey, nearly 20% of respondents have carried out formaldehyde detection, and nearly 70% of respondents said that formaldehyde will be considered in the future. For those who have been tested for formaldehyde, the main detection methods are adopted:
检测盒自测
Test box self-test
电子检测仪自测
Electronic testing instrument self-test
委托除甲醛企业检测
Inspection of entrusted formaldehyde removal Enterprises
委托专业检测机构检测
Commissioned professional testing institutions to detect
调查显示，大部分受访者还是比较信任电子检测仪和检测和自测结果。
The survey showed that the majority of respondents still trusted electronic detector and test and self-test results.

大家倾向开窗通风、曝晒的除甲醛方式
People tend to window ventilation, exposure to formaldehyde removal mode
开窗通风、曝晒是除甲醛的为大众首选
Window ventilation, insolation is the first choice for the public except formaldehyde
除甲醛方式五花八门，开窗通风、曝晒是受访者最倾向选择的除甲醛方式，
In addition to the variety of formaldehyde, fenestration ventilation, exposure is the most preferred way of formaldehyde removal,
其次是放置绿色植物，再次是放置柚子皮等天然吸附性物品，购买除甲醛类产品的占比排名第四，不到一成的受访者使用带除甲醛功能的电器产品，而委托专业机构除甲醛的占比则最少。
The second is placed green plants, again placing grapefruit skin and other natural absorbent articles, buy products in addition to formaldehyde proportion ranked fourth, less than 10% of the respondents with the use of electrical products in addition to formaldehyde function, and entrust professional institutions in addition to formaldehyde accounted for at least.
我们还发现，相对男性来说，女性更加注重居住环境的除甲醛问题，在开窗通风、放置绿色植物、购买除甲醛类产品的比例上都要高于男性，而男性对使用带除甲醛功能的电器、委托专业机构除甲醛的比例要略高于女性。
We also found that compared to men, women pay more attention to the problem of formaldehyde in the living environment, in the ventilation window, placed green plants, in addition to formaldehyde to buy products the ratio of all higher than men, and men to use with function of removing formaldehyde, electrical appliances, entrust professional institutions in addition to formaldehyde is slightly higher than the proportion of women.

“高科技”除甲醛方法你试过吗？
Have you tried the "high-tech" formaldehyde removal method?
在光触媒除甲醛产品领域，受访者对进口产品并无特别偏好
In the field of Photocatalyst formaldehyde removal, the respondents had no preference for imported products
光触媒是一种以纳米级二氧化钛为代表的具有光催化功能的光半导体材料的总称，在紫外线的作用下发生光催化反应，能降解甲醛等空气污染物。
Photocatalyst is a general name of optical semiconductor material with nanometer titanium dioxide as the representative, which has photocatalytic function. Photocatalytic reaction under ultraviolet radiation can degrade formaldehyde and other air pollutants.
受访者在在光触媒除甲醛产品领域，对进口产品并无特别偏好。
Respondents have no preference for imported products in the field of photocatalyst de formaldehyde products.
一般的光触媒产品要满足在紫外线光波长以内的光波照射下等一定的条件，才会达成可能的效果，所以在选购时，要了解清楚所选的光触媒产品是否配有相应的紫外线灯，还是需要另行安装。但紫外线对眼睛和皮肤有损伤，开启后要确保无人在场。
The photocatalyst products in general to meet within the ultraviolet light irradiation wavelengths under certain conditions, will achieve the effect, so at the time of purchase, to understand clearly the selected photocatalyst products are equipped with ultraviolet lamp accordingly, still need to be installed. But UV damage to the eyes and skin, open to ensure that no one is present.
还需确认产品的平均粒径是否达到10纳米以内。
It is also necessary to confirm whether the average particle size is within 10 nanometers.
使用时，如果附着于墙壁等地方的光触媒产品被擦拭弄掉了，也无法起作用。
When used, if the attachment to the wall and other places of the photocatalyst products were wiped out, and can not work.

除甲醛产品最重要的是——本身无害
The most important thing except formaldehyde products is harmless
“产品本身无危害”是消费者选择除甲醛产品最重视的原则
"The product itself is no harm" is the most important principle for consumers to choose formaldehyde products
除甲醛产品具有广泛的消费群体，市场空间较大。具体到除甲醛产品，选择如下图，其中值得注意的是，空气清新剂并无除甲醛功能，但仍有25.7%的受访者使用。
In addition to formaldehyde products have a wide range of consumer groups, the market space is larger. Specific to the formaldehyde products, choose the following picture, which is noteworthy, air freshener without formaldehyde function, but still 25.7% of respondents use.
在除甲醛产品的效果方面，选择活性炭的受访者比例最高，达38.9%；甲醛清除剂次之，占比28.1%；然后是各类绿色植物，以及柚子皮茶叶等天然吸附性物品；空气净化器占比14.6%，也得到一定程度的认可。
In addition to formaldehyde products, activated carbon choose the highest percentage of respondents, up to 38.9% times; formaldehyde scavenger, accounting for 28.1%; and all kinds of green plants, and pomelo peel tea and other natural absorbent articles; air purifier accounted for more than 14.6%, has also been a certain degree of recognition.
对于除甲醛产品的选择，产品本身无危害是受访者最重视的原则，然后才是价格更低、效果更彻底、见效更快。
For the choice of formaldehyde products, the product itself is no harm, is the most important principle of the respondents, and then the price is lower, the effect is more thorough, faster effect.
活性炭是本次调查中受访者使用率最高和普遍认为效果佳的除甲醛产品。它主要依靠自身的孔隙结构，被动吸附那些“飘”过来的有害气体，达到净化空气的作用。优质的活性炭产品应为疏松结构的黑色粉末或颗粒，无异味，如果产品有板结、气味异常等情况请不要购买。
Activated carbon is the highest utilization rate of respondents in the survey and is generally believed to be good effect of formaldehyde removal products. It mainly relies on its own pore structure, passive adsorption of those "floating" harmful gas, to purify the air. High quality activated carbon products should be loose structure of black powder or particles, no peculiar smell, if the product has harden, smell abnormal and so on, please don't buy.
使用时应注意，活性炭达到吸附饱和状态后可能会把空隙里的有害气体再释放回空气里，所以使用48小时左右，宜到室外通风处晾晒。
It should be noted that when activated carbon reaches saturation state, the harmful gas in the gap may be released back into the air. Therefore, it is advisable to use air for 48 hours or so to dry in the outdoor ventilation.
