How to Guarantee Fresh Air at Home 空气质量检测！如何保证家里的新鲜空气

We care about air quality at YCIS Beijing and we recently completed our programme of air quality tests in Building G following the Learning Community renovations. We ask the experts from Pure Living to explain more. 

我们关注北京耀中的空气质量，最近我们在新装修的学习社区完成了G楼的空气质量检测。我们采访了Pure Living的专家。

Please explain the key results of the test and what this means

请解释测试的关键结果及其含义

We have run a series of tests for formaldehyde in all areas on the 2nd floor of Building G. There were no points of failure for formaldehyde anywhere and the average indoor formaldehyde level was 30% of the national safety standard limit. 

我们在G楼二层的所有区域进行了一系列甲醛测试。测试覆盖了全部区域，平均室内甲醛含量是国家安全标准限值的30％。

Why should we use a company such as Pure Living, and not conduct these tests ourselves?

我们为什么要请Pure Living这样的公司，而不是自己进行这些测试？

Common AQI readers for personal use are not adequate for testing the presence of volatile organic compounds (VOCs) such as formaldehyde. The only way to be sure of VOC pollutant levels is by using laboratory analysis.

一般供个人使用的AQI检测仪不足以测试甲醛等挥发性有机化合物（VOC）的存在。检测VOC污染物水平的唯一方法是实验室分析。

What can families do at home to improve their air quality?

在家如何改善空气质量？

In Beijing, many people are concerned about particulate matter (PM2.5) which is caused by combustion. This can be monitored at home with common AQI monitors. The best way to keep PM2.5 down at home is to purchase air filters and keep your windows closed when the pollution is high outside. 

在北京，很多人担心燃烧产生的颗粒物质（PM2.5）。这可以在家中使用常见的AQI检测仪进行监控。在家中降低PM2.5的最佳方法是购买空气净化器，并在空气污染很严重时禁闭窗户。

Formaldehyde is present in new furniture, renovation materials and household cleaning products. The best way to reduce the presence of formaldehyde is to increase ventilation: open your windows (when the pollution is low!) or keep your fresh air system switched on.

新家具、装修材料和家用清洁产品中含有甲醛。减少甲醛存在的最佳方法是通风：打开窗户（当污染很低时！）或打开新风系统。
