With purifiers and lawsuits, Pakistanis fight back against smog

December 30, 2019

LAHORE, PAKISTAN - For the past few months Hasan Zaidi's phone has been ringing nonstop with calls from desperate residents in Pakistan hoping to get their hands on his newly invented air purifier as smog blankets the country.

"Some days, I had so many calls that I couldn't answer," says Zaidi during a recent interview with AFP in his workshop.

Tired of choking on putrid air, Zaidi spent six months perfecting his homemade device as he looked for a low-cost solution to battle the increasingly toxic scourge overwhelming Pakistan.

During this winter alone the 31-year-old engineer has already sold some 500 units, which are priced at just 16,000 Pakistani rupees ($103), but admits to refusing hundreds of orders in recent weeks due to lack of manpower and resources.

In cash-strapped Pakistan Zaidi's "Indoor Forest" purifiers are cheaper than imported models, which typically cost about two to five times more.

"Now it is less of a luxury and more of a necessity," explains Sadia Khan, whose company Autosoft Dynamics recently acquired a dozen of Zaidi's purifiers so his 180 employees can "breathe safely".

In the past five years, air pollution has worsened in Pakistan, as a mixture of low-grade diesel fumes, smoke from seasonal crop burn off, and colder winter temperatures coalesce into stagnant clouds of smog.

In 2015, 135,000 Pakistanis died due to poor air quality, according to a study published in the scientific journal The Lancet.

Pollution tends to be at its worst in the country's eastern province of Punjab during winter, particularly in the 12-million strong city of Lahore near the border with India.

In November schools were closed for several days across the province with the level of PM2.5 -- tiny particles that get into the bloodstream and vital organs -- repeatedly exceeding 200 micrograms per cubic meter of air.

The World Health Organization's recommended safe daily maximum is a measurement of 25.

Pakistan is ranked one of the worst countries in the world for air quality and Lahore consistently ranked in the top 10 most smog-hit cities, according to the pollution monitoring site AirVisual.

But Tanveer Waraich, director general of the Punjab's environmental agency, dismisses those figures, saying pollution readings cited by monitors and activists are not from "authentic machines".

"To say that Pakistan and Lahore are among the top polluted cities... this statement is not based on facts," he says, but concedes the country's air quality is largely unacceptable.

Public awareness about the issue is growing due to increased activism on social media about the dangers of pollution and the dire challenges climate change is bringing to Pakistan. -AFP
