当雾霾久久挥散不去，当呼吸新鲜的空气、享受湛蓝的天空成为一种奢侈，穹顶之下的我们应该如何应对呢？为了对抗雾霾，世界各地的创新达人设计出了各种创意十足的空气净化妙招。快随本文一起来开开眼吧，说不定你会为之心动哦！

Beijing is hardly alone in its air pollution woes1）. The World Health Organization has said that roughly half of the world's urban population is exposed to pollution at least 2.5 times higher than it recommends.

While it may take years to fix this global problem， innovative minds in the Asia region have come up with creative solutions for living with air pollution.

在空气污染问题上，北京一点都不孤单。世界卫生组织表示，全球约有半数的城市人口生活在污染程度至少2.5倍于其推荐标准的环境之中（编注：英文原文发表于2014年7月）。

虽然解决这个全球性的问题或许还需要许多年的时间，但在亚洲地区，一些创新达人已经为在有空气污染的环境中生活提出了各具创意的解决方案。

DIY Purifier

Thomas Talhelm started worrying about the air inside his Beijing home during "airpocalypse2）" in 2013 when Beijing's air quality index skyrocketed to a terrifying 755—a 500 reading is considered hazardous3） for health， meaning people should avoid outdoor activity.

The Fulbright4） scholar couldn't afford the luxury of5） an expensive air purifier. "Filters are actually very simple—an HEPA6） filter is all you need to get over 96% of the PM2.5，" he said， referring to particulate7） matter smaller than 2.5 micrometers that can penetrate deep into lungs， leading to fatal diseases.

With three of his friends， Talhelm created Smart Air8）， an air purifier consisting of a basic household fan with an HEPA filter attached to it.

It works as efficiently as the big brands selling for thousands of dollars， removing more than 90 percent of PM2.5 in your room， according to Talhelm's research.

Clean Air Forecasts

A blue sky may be rare in Beijing， but when it appears， the city becomes a beautiful place to live.

Dustin Grzesik， the former Beijing resident created a free website and a free Android app—they share the same content and both forecast the next clean air day based on weather patterns.

Grzesik， who is now based in San Francisco， created the website （Banshirne！9）） and the app （Beijing Smogcast） by observing Beijing's weather reports， air quality reports and the US embassy's Air Quality Index Twitter feed.

Invisible Mask

Infipure's10） "nose mask" claims to cut 99% of PM2.5 without the bulkiness of a surgical face mask.

The disposable11） filters， made from non-toxic， latex12）-free materials， are inserted into your nostrils and aim to be undetectable.

"People care about their health， but don't want all the downsides that come with a traditional face mask，" Infipure co-founder Francis Law explained.

Master Battery

Stanford professor Cui Yi and his team have developed a high-energy battery that could potentially increase an electric car's mileage by three times without being recharged.

The nanotube13） lithium14）-ion15） battery is said to outlast current conventional batteries. After 1，000 charging cycles， the battery still retains over half its energy capacity.

Yi's invention can help bolster16） the appeal of electric cars since cheaper， high-energy batteries are needed to compete against traditional vehicles.

Plant Backpack

Taiwanese artist Chiu Chih has designed a survival kit for an apocalyptic world.

Dubbed17） "Voyage on the Planet"， a potted plant is housed inside a clear backpack hooked up to two tubes to funnel18） fresh air into a face mask. It's a bold， abstract take19） on an oxygen tank.

自制净化器

空气质量指数达到500即被认为有害健康，意味着人们应该避免户外活动。所以在2013年，当“空气末日”来临时（当时北京的空气质量指数飙升到了骇人的755），托马斯·塔尔赫尔姆开始为北京家中的空气质量感到担忧了。

这位富布莱特学者享受不起昂贵的空气净化器。“过滤器其实非常简单——你只需一个高效空气过滤器就可过滤掉96%的PM2.5。”他所说的PM2.5是指直径小于2.5微米、能够深入肺部引起致命疾病的颗粒物质。

塔尔赫尔姆和三个朋友一起用一台简单的家用风扇外加一个高效空气过滤器制作出了“聪明空气”空气净化器。

根据塔尔赫尔姆的研究，这台净化器和售价数千美金的各大名牌产品同样有效，能够去除房间中90%以上的PM2.5。

洁净空气预报

在北京，蓝天也许难得一见，但在有蓝天的日子里，这座城市就会变成一个宜居的美丽地方。……
