VOCs: Invisible Killers in Your Home & Office II


In our last article “VOCs: Invisible Killers in Your Home & Office“, we talked about sources of chemical pollutants in your home & office and how to reduce exposure. In this article, we look at professional testing & remediation services.

在上一篇文章“VOCs:家庭和办公室的隐形杀手”中,我们谈了家庭和办公室中化学污染物的来源以及如何清除。这篇文章,我们将会介绍境纯环境的专业检测治理服务

At PureLiving, we always recommend testing prior to taking any professional remediation steps due to the fact that, with accurate data and analysis we will then be able to identify pollutants, pinpoint sources, and recommend the most appropriate solutions.  For example, installing a HEPA-only air purifier into a home with strong chemical odors will not solve the VOC issue.  In fact, it may lead to a false perception of safety––occupants will “feel” safe while in reality they are sitting in a potentially hazardous environment. Another example is if the source of VOC was your wooden bookcase, it would be more affordable and efficient to recommend removal of the bookcase rather than perform PCO (photocatalytic oxidization) treatment throughout your entire apartment! 

在境纯环境,我们始终强调在实施任何专业清除作业之前,先进行空气检测。原因是,只有基于准确的数据和分析,我们才能够确定污染物的种类,查明来源,从而推荐最合适的解决方案。例如,在一个化学气味严重的家里安装一台只有HEPA滤网的空气净化器并不能解决VOC问题。事实上,这还可能造成错误的“安全感”–居住者身处有潜在危险的环境中,却以为是“安全”的。又比如,如果检测出来污染源是你的木质书架,搬走这个书架会比对整个公寓进行PCO光化学处理更经济有效。

To help you understand your environment, PureLiving has designed a Chemical Investigation package, which uses a combination of real-time chemical sensors and certified laboratory analysis to precisely identify TVOC sources and levels in air and common household furnishings/objects.

为了帮助您了解自己的室内环境状况,境纯环境设计了一个化学气体检测套餐,组合使用实时化学探测器和认证级实验室的数据分析,来识别TVOC的来源并分析其在空气、家具、物体中的数量级。

This testing package is comprised of three components: air testing (3 points), TVOC sniffer testing (3 sources)and package bonus.

这个检测套餐包括三个组成部分:空气采样(3个点位),TVOC点源检测(3个点源)以及套餐优惠。

 

For professional remediation, photocatalytic oxidization is a type of remediation where a chemical (typically titanium dioxide TiO2) is vaporized and applied to furniture, walls, and floors in a room with high levels of odor or VOCs. The Titanium dioxide-coating decomposes nitrogen oxide (NOx), formaldehyde, benzene and other volatile organic compounds (VOC) in the air.

在专业清除手段方面,光触媒技术利用化学物(通常为二氧化钛),将其喷洒于家具、墙壁和地板等物体表面,用于处理室内较高的VOC和气味水平。喷洒的二氧化钛能够降解空气中的氮氧化物、甲醛、苯等挥发性有机化合物(VOCs)。

The coated surfaces then become the treatment area.  When exposed to UV light, TiO2 becomes a photo catalyst oxidizer (PCO). The TiO2 facilitates the oxidation process of carbon bonds (which keeps most organic compounds like germs together) through a photocatalytic reaction. This reaction breaks up these bonds over and over again until only carbon dioxide and water (safe substances) are left behind.

被喷洒的物体表面就成为了治理区域。当紫外线照射时,二氧化钛就变成了光催化氧化剂(PCO)。碳氧键(形成大多数的有机化合物、细菌的结构)在TiO2的催化氧化作用下产生光化学反应而断裂,经过一轮一轮的作用下,最终只留下CO2和水(安全物质)

In our experience, PCO treatment is most appropriate when levels of TVOCs or other gases are more than twice the safe level and need to be immediately reduced.  PCO treatment generally has an immediate effect of 40-90% reduction in levels. Approved by the United States Food and Drug Administration (FDA), it is considered a safe substance that is harmless to humans.

以我们的经验来看,PCO治理是TVOC或者其它气体超过安全值两倍级以上、必须马上处理时最合适的方式,通常可以立即降低40%–90%的污染物。经美国食品药品管理局(FDA)认证,这是一种对人体无害的方式。

The process leaves behind a clear layer which continues to inhibit gas release and is antimicrobial as well.  The clear layer will have no effect on surfaces nor will it change the texture of fabrics and furnishings. The oxidization process works better with light (artificial or natural sunlight), but also works (though at approximately 30-50% effectiveness) in darkness.治理过后留下的二氧化钛层的保护作用并没有结束,它将持续抑制气体的释放同时抗菌。这个保护层即不会损坏物体表面,也不会改变家具和织物的纹理。氧化过程最好有光(人工或自然光均可),在黑暗中也能发生反应(有效性约为30-50%)。

The coated surface’s lifetime can last between five and ten years, depending on the treatment of the coated surface and the surrounding conditions. Besides, re-testing is always recommended after initial application to check the effects.

被处理的表面有效时长可持续5-10年,取决于使用情况以及周围环境状况。另外,在初次治理后,我们都建议对室内空气进行采样复测以评估治理效果。

In addition, purifiers containing active carbon/charcoal media can help control chemical off-gassing in the indoor environment (carbon filters can help aid in chemical absorption but should not be used in-lieu of fresh air ventilation).  BlueAir purifiers with Smokestop filters can not only control chemical build up, but are designed stylishly to fit seamlessly into any home or office.  Their contemporary look has earned the Excellent Swedish Design award, one of the most prestigious in the industry.

另外,含有活性炭的净化器能够帮助控制室内的化学物浓度(活性炭滤网能够吸附化学物质,但不能取代新鲜空气,房间还是要进行通风)。使用复合滤网的BlueAir空气净化器不仅能控制化学气体水平,同时其设计时髦,能够无缝化融入任何家庭或办公室。时髦的外表为其赢得了设计业内最著名的奖项之一的瑞典优秀设计奖。

 

· The NGB Smokestop filter is composed of:Particle (HEPA) layer and Carbon layer

  新国标复合滤网由两种滤网组合而成:粒子层(HEPA)和活性炭层

· The carbon layer eliminates odor, formaldehyde and VOC’s effectively, up to 98% removal rate

  活性炭层作用于特殊气味、甲醛和VOCs, 清除率高达98%以上

· The Particle (HEPA) layer captures 99.97% of all airborne particles (like pollen, dust, and pet dander particles) down to 0.1 micron in size

  粒子(HEPA)滤网能够捕捉空气中99.97%直径小于0.1微米的颗粒物(如花粉、灰尘和宠物毛屑颗粒)

· For heavily polluted air with odors, formaldehyde & VOCs  (e.g. recently furnished), the carbon layer can be replaced earlier

  对于污染严重且有明显气味、甲醛和VOCs的空气(例如,新装修的房间),活性炭层需要提早更换

· The Particle (HEPA) filter can be used on its own if chemicals filtering is not required. The carbon filter is not a standalone filter. For chemicals reduction, the Smokestop NGB version is recommended.

  如果没有化学物质污染,可以仅使用粒子(HEPA)滤网。活性炭滤网不能单独使用,如果需要去除化学物质,推荐使用复合滤网
