air bubble shield for dangerous smog to be tested in beijing - most effective air purifier

The device creates a bubble that protects people from 70% of the harmful pollutants that first appeared in Beijing next month, as the capital of China, there is often a toxic haze.
The outdoor air purifier has a canopy and created an area that tries to cover air curtain protection for about 20 people.

In January, Beijing's leaders said they would spend £ 10. 8 billion yuan ($1. 74 billion)
After the city failed to meet its target of reducing smog last year, it responded to air pollution.
The level of pm2. 5 in Beijing raised public concerns in 2013.
5. tiny particles that pose the greatest risk to human health are 35 times the World Health Organization's recommended limit.
At the beginning of 2014, the city's air stayed at dangerous levels again for a week.
The cost of technology and prototype development for air purifiers is approximately HK $600,000 ($77,391).
It is expected to be used at Tsinghua University in Beijing from June.
Chief inventor Jimmy Tong said in Hong Kong that the partners had answered inquiries from commercial building owners and Chinese officials who were interested in transforming the technology into the canopy and facade of the building.
Tong, 38, an engineer with a PhD in fluid dynamics from the University of Minnesota, has experience in designing wind turbines and rocket launchers.
The test of the new outdoor air purifier started at the busy Queen's Road East in Hong Kong and showed a 30% to 70% reduction in PM 2.
5 for users standing under the unit canopy, which is located in front of the new residential development project in China.
Partners have applied for patents for their machines.
Under the Canopy, the air is filtered like an indoor air purifier.
This machine is unable to remove nitrogen oxides, a common pollutant on the roadside.
Tong said he first wanted to filter out the most pressing problem: particulate matter.
He said he was considering applying different filters to eventually help the machine screen out other harmful substances.

The company is working on a cost
An effective way to expand production in the event of demand from government agencies.
All over the world, people filter dirty air in various ways.
Some cities plant trees in polluted areas.
Peru University of Engineering and Technology posted a billboard for filtering air in the middle of a construction site in Lima;
A few years ago, a giant air freshener was installed in the center of New Delhi.
"We certainly welcome any new technology to reduce human exposure to pollutants," Sum said . "
