Air purifiers at traffic intersections: Experts call it mere band-aid fix

In a rather desperate move to counter the severe air pollution in Delhi, the government wants to install air purifiers at traffic intersections. But experts feel the idea is flawed on various counts. While this is more of a band-aid solution that doesn’t bring down vehicular emissions, the system may also not be as effective in “purifying” polluted air.

Each device, it is claimed, helps purify the air of up to 40% pollutants, including particulate matter, carbon monoxide and hydrocarbons, over a 30-metre radius. However, the results when the New Delhi Municipal Council installed a similar air purifier in Connaught Place in 2010 weren’t great, and the machine was soon dismantled.


“It did not prove very effective. You have to understand that the air purifier has to have a huge capacity to be able to filter all the pollution,” an NDMC official told TOI. “We installed it more for demonstration and did not even pay the company then.” He, however, added that NDMC was now thinking of reassessing the effectiveness of the machine because air quality has deteriorated so much.

The air purifiers being currently considered by Delhi government are a bit different. They have been designed by the National Environmental Engineering Research Institute (NEERI) and IIT Mumbai and manufactured by a Kerala-based company. These can filter particulate matter, carbon monoxide and hydrocarbons. The team is working on filtration of oxides of nitrogen (NOx) too, but that may take over a year. Delhi government’s press release on Friday said though that they could monitor NOx as well.

Each purifier costs Rs 1 lakh or so. A busy intersection could require up to five of them, depending on the area being covered. On trial in Mumbai at present, the results could determine whether the Maharashtra government will deploy them in parts of that city. A Maharashtra Pollution Control Board official said the trial for a single installation cost them about Rs 20 lakh.

“The system also creates turbulence that helps pollutants to disperse, which is helpful in Delhi’s calm winter when pollutants tend to remain concentrated near the road surface,” elaborated Rakesh Kumar, director, NEERI. The purifiers run on electricity, but can be operated on solar power too. Each machine being test run in Mumbai costs just around Rs 30 a day. China is planning to operate similar purifiers in some locations on a pilot test.

Experts, however, are not too taken by the idea of using the machines. “Air purifiers are definitely not effective, though virtual chimneys that create turbulence may help a little,” said a scientist at an air pollution monitoring agency.

Another expert, Anumita Roy Chowdhury, head of the clean air campaign at the Centre for Science and Environment, said that the use of machines to purify air at a few traffic intersections was a cosmetic measure at best. “The money could have been used more productively to reduce pollution from different sources,” she said. “We cannot afford to make expensive mistakes.”

 

The world’s largest air purifier is turning Beijing’s dirty air into diamonds

As smog season starts to hit China, Studio Roosegaarde, a design team led by award-winning Dutch designer Daan Roosegaarde, unveiled their pollution-fighting Smog Free Tower in Beijing last Thursday.

According to the press release, at 7 meters in height, the Smog Free Tower is the largest air purifier in the world — and it’s mobile! Meaning that it can help to clean up other cities if it ever runs out of smog to eat in Beijing.Reuters reports that the tower sucks in 75% of the particles in the nearby air that are dangerous to humans, and then spits back out clean air into the surrounding space.

The classroom should be installed air purifier cited hot.

As schools in Beijing and other parts of northeastern China suspend classes because of the red alert over air pollution, many parents are demanding that air purifiers should be installed for the students.

With major pollution days becoming more frequent, students are staying home, often without supervision. Their parents say it would be better if their children were in the classroom, and that’s why schools need to install air purifiers.

“Our school bought air filters last year. We did a little fund raising, with each parent throwing in several hundred for that. We’ve already bought two air cleaners for the class, both of which are installed.”

Why does indoor air quality matter?

The U.S. Environmental Protection Agency (EPA) now lists indoor air pollution among the top five environmental health risks that the U.S population currently faces, and warns that your indoor air is, on average, 2 to 5x more polluted than outdoor air. Since you and your family spend up to 90% of your time indoors, removing particles like dust, chemical and and mold particles with an air purifier can relieve your body of a major stress.

When airborne particles are inhaled, they can damage your lungs and cardiovascular system—the extent and severity of damage is directly related to particle size, as well as length and degree of exposure. Anyone with asthma knows that the outdoor air quality can have a big impact on breathing. But even if you don’t have asthma, you’re probably familiar with allergies, sleep apnea, lung disease or other health concerns related to air quality. Air pollution is particularly dangerous for children, people with asthma and other lung diseases, people over 65, people working or exercising outdoors, anyone who has diabetes, cardiovascular disease, high blood pressure, or who has suffered a heart attack or stroke.

 

Indoor air commonly contains microscopic particles made of:

  • dust
  • chemical fumes
  • gases
  • smoke
  • skin flakes
  • mold
  • roach excrement
  • pollen
  • animal dander

Exposure to poor air quality can lead to:

  • Allergies
  • Asthma attacks
  • COPD
  • MCS
  • Lung Disease

How to Protect Yourself

Airborne particles vary in size. Depending on which of these particles are causing aggravation, there is a home air purifier that performs to remove these particles from the air. Air purifier filters with the HEPA classification capture 99.97% of particles that are 0.3 microns and will target most of the contaminants shown in the shaded region below. For contaminants outside the shaded region, including smoke, smog, chemicals, and viruses, specialty air purifiers or filters are designed with specific technology to target those concerns.
