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.”

What is HEPA Air Purifier?

HEPA stands for High-Efficiency Particulate Air, and is a filter type that’s designed to adsorb air contaminants such as pet dander, pollen, tobacco smoke, mold, dust, and dust mites. It’s used extensively to improve indoor air quality, especially for environments that need to be scrubbed of allergens for people suffering from allergies and asthma.

HEPA stands for High-Efficiency Particulate Air, and is a filter type that’s designed to adsorb air contaminants such as pet dander, pollen, tobacco smoke, mold, dust, and dust mites. It’s used extensively to improve indoor air quality, especially for environments that need to be scrubbed of allergens for people suffering from allergies and asthma.

HEPA Filter Definition:

A high-efficiency air filter designed with randomly arranged, fiberglass fibers. Also known as a depth filter, its porous design retains particulates of a specific size (depending on the filter grade), ensuring that they aren’t released back into the environment. Due to the nature of the design, these filters can hold a significant amount of waste before requiring replacement.

China to deploy the world’s largest outdoor air purifier in Beijing

China will deploy world’s largest outdoor air purifier designed by a Dutch engineer in its smog- hit capital Beijing, as the thick heavily-polluted haze returned to haunt the city, driving people indoors. The seven-meter-tall tower, brainchild of Dutch designer Daan Roosegaarde, is undergoing last-minute checks in Beijing’s 751 D Park art area. The ‘Smog Free Tower’ will soon be opened to the public, and will be toured across the country, state-run Global Times said, quoting China Forum of Environmental Journalists, an NGO under China’s Ministry of Environmental Protection.

The tower can capture about 75 percent of PM 2.5 and PM 10 tiny particles in its vicinity and then release purified air to create a “bubble” of fresh air around it. The tower can clean 30,000 cubic meters of air per hour through its patented ozone-free ion technology. Beijing has been plagued with heavy smog since the beginning of October. The city’s environmental authorities issued a “yellow alert” for air pollution on Tuesday. “Yellow alert” is the third-most serious level in a four tier color-code warning system. Red is the most serious and orange the second-most serious while blue is the least serious pollution level.

The average PM2.5 density of the small deadly polluted particles crossed over 300 today even though a cold front in the morning cleared the smog a bit. Liu Guozheng, CFEJ secretary-general said the tower is intended to warn authorities never to forget their duty and encourage the public to pull together to combat the smog. The public, meanwhile, are bemused by the tower’s function and have called on authorities to curb dangerous sources of polluting particles, the daily said.

One-quarter of air purifiers fall short of quality standard

One-quarter of air purifiers sold on the domestic market are substandard, an inspection by China’s top quality authority showed.

The inspection, conducted in the first half of this year, found 15 of the 61 batches of products were substandard, according to the General Administration of Quality Supervision, Inspection and Quarantine.

This is the first time that the administration has organized a national quality inspection aimed at air purifiers, and the inspection covered most well-known air purifier brands available in China, said Zhang Wenbing, chief for quality supervision at the administration.

The inspection covered nearly 20 percent of China’s air purifier producers, and of the models by big enterprises, 90 percent were up to standard, much higher than average, according to the administration.

No products by big brands such as Honeywell, Samsung and Midea were found to be substandard.

However, purifiers made by Chinese firms Guangdong Jingba Technology Co. and Shanghai Xinsong Electronics Co. were found to be substandard, due to respective issues of failing to remove methanol and failing noise standards.

“Results of the inspection can provide the basis for consumers to choose air purifiers,” said Song Guangsheng, director of the National Quality Supervision and Inspection Center for Indoor Environment and Environmental Products.

With increasing demand for purifiers in recent years, the number of producers has also risen, but many purifiers on the market may not work as well as advertised, he said.

“Many air purifier brands claim to be able to remove methanol, but in fact, few of them are able to do so,” Song said.

In the first half of the year, 4.5 million air purifiers were sold in China, 58 percent more than the same period last year, according to media reports.

Zhang Xiao, an inspector at the National Quality Inspection Center for Household Electrical Appliances, said China has strict quality standards for air purifiers, and some key indexes include noise level, capacity to remove pollutants and purifiers’ toxic emissions.

‘Smog Free Tower’, largest air purifier in Beijing, sparks controversy

A “Smog Free Tower” undergoing tests in Beijing’s famed 798 art zone has sparked controversy amid continuous heavy smog in the last couple of days.

The seven-meter-high metal structure, designed by Dutch artist Daan Roosegaarde and introduced to the Chinese capital as the world’s largest air purifier in late September, opened for testing and adjustment recently.

Olans air purifier OLS-K04 1

The tower boasts a capacity to purify 30,000 cubic meters of air per hour and an ability to capture at least 75 percent of PM 2.5 and PM 10 particles, creating a fresh-air area around the tower, China Youth Daily reported.

The designer also said that particles collected by the tower could be processed into black gems.

Some experts questioned the usefulness of the newly-installed air purifying tower. According to calculations by an expert, it can absorb merely 4.5 grams of PM 2.5 an hour on heavy pollution days, which is less than the equivalent of a spoonful of salt, the paper reported.

“It would work better to have the construction site covered by a piece of cloth,” the expert joked.

In other cities, various facilities aimed to combat smog have also been installed. “Perhaps people are desperate about combating smog,” commented He Jijiang of Tsinghua University.

But those smog-treating facilities are only experimental and cannot solve the fundamental problems, He said.

Beijing was again shrouded in smog, with particle concentration in the air continuing to rise from midday on Tuesday, and the heavy pollution had lasted 19 hours as of midday Wednesday.

Six of the capital’s monitoring sites reported heavy pollution, which continued to worsen, prompting the Beijing Meteorological Service to issue a yellow alert for air pollution on Wednesday, the fifth of its kind since the beginning of October.

Static Electricity: A Spark of Interest

We’ve all have experienced static electricity in one way or another. Those unexpected little shocks we get when we touch a doorknob or some other metallic object, the balloons that stick to the wall after being rubbed in the head, or hair itself standing straight when it comes close, all are produced by static electricity. Most of the time it is produced when two objects come in contact or are rubbed together.

What is Static Electricity?

All materials are made up of molecules, and all molecules have tiny atoms, with positively charged protons, neutral neutrons, and negatively charged electrons. Most of the time an atom is neutral with the same number of protons and electrons. When an atom’s proton and electron numbers are uneven, the electron dance begins. If you place two different materials next to each other, electrons will start jumping from one material to the other.

Static electricity is generated when any material gains or loses electrons and becomes positively (when it loses electrons) or negatively charged (when it gains electrons). The accumulated charges are what’s called static electricity. Conductive materials like metals and carbon hold onto their electrons tightly, whereas insulating materials, such as plastic, can be charged by friction because they easily gain or lose electrons.

In 600 BC, the Greek philosopher Thales[1] observed that some combinations of materials have more potential to make sparks fly than others. Materials can be catalogued in order of their tendency to become charged, from positive to negative. The lower an item sits on the list, the more likely it will attract more electrons and become negatively charged. Rubbing objects far from each other on the list creates a bigger charge than objects closer together. For example, polishing a glass plate with a silk scarf electrifies the scarf so that it acts like a magnet.

When you stride across a wool carpet in leather shoes, your shoes pick up extra electrons from the carpet with each step. By the time you lift your foot up off the ground, the electrons will have spread around your entire body, giving you a negative charge. The next time you put your foot on the carpet, your shoe doesn’t have any extra electrons, but your head might. So more electrons make the leap to your foot.

“As you keep walking across the floor, you become full of electrons,” said Todd Hubing, from the Electromagnetic Compatibility Laboratory at the University of Missouri-Rolla. “Eventually more electrons don’t want to come up on you because you’re so charged up. You end up with a high voltage, about 20,000 to 25,000 volts.” That’s serious power at your fingertips, considering a normal electrical outlet on the wall is only around 100 volts[2] of electricity.

Practical Uses of Static Charges

Dust removal: There are some appliances that can eliminate dust from the air, like air purifiers. They use static electricity to alter the charges in the dust particles so that they stick to a filter of the purifier that has an opposite charge as that of the dust (opposite charges attract each other). This effect is also used in industrial smokestacks to reduce the pollution that they generate. The effect is basically the same as the home air purifier.95g58picmfk_1024.

Photocopy: Copy machines use static electricity to make ink get attracted to the areas where we need the information copied. It uses the charges to apply the ink only in the areas where the paper to be copied is darker (usually this means text or other information) and not where the paper is white, this process is called xerography.

Car painting: To make sure a car’s paint is uniform and that it will resist the high speeds and weather to protect the car’s metal interior, it is applied with a static charge. The metal body of the car is submerged in a substance that charges it positively, and the paint is charged negatively.

This process ensures a uniform layer of paint, since when there is enough negative paint in the car the extra will be repelled by the paint already in the car. It also ensures that the paint won’t fall off.
