As the city grapples with dangerous levels of air pollution, a Delhi-based start-up has designed a 40-feet-tall purifier which it claims could provide clean air to 75,000 people living in the three-kilometre radius around it.

Kurin Systems has recently got the patent for the "world's largest as well as the strongest air purifier" published by the World Intellectual Property Organization, its co-founder Pavneet Singh Puri said.

Specially designed keeping the national capital’s air condition in mind, a single one of these purifiers can provide clean air in the three-km radius of their placement impacting the lives of 75,000 people.

According to the World Health Organization (WHO), India is home to six of the top 10 polluted cities in the world with Delhi topping the list.

As many as 1.2 million people die every year in India due to air pollution, a Greenpeace report published last year showed.

The purifier, which Kurin calls the 'City Cleaner' measures 40 feet in height and 20 feet on each side. It will have the capacity to clean 32 million cubic metres of air per day, its makers said.

The device will be able to take in air from all 360-degree angles and generate 1,300,000 cubic metres of clean air per hour, they said.

The air will be purified by using the highly effective H14 grade highly effective particulate arrestance (HEPA) filter which can clean up to 99.99 per cent of the particulate matter present in the air in conjunction with a pre-filter and activated carbon.

The mammoth purifier will have 48 fans to keep the flow of clean air going. The device will run on energy generated via solar panels and will be made with materials sourced locally.

Kurin City Cleaner will use nine stages of physical filters to clean out 99.99 per cent pollutants from the air.

There are nine filtration stages followed by centrifugal force in a way to maximise the clear air delivery rate of the entire tower.

Puri noted that the tower can be completed within four months of getting it sanctioned from the authorities.

The expected price range of the purifier would be between Rs 17.5 million to Rs 20 million per tower, he said.

The company has scale models ready that can be tested in any environment with PM levels as high as 2000.
