Made-in-India Smog Tower Spells Hope For Delhi, Can Clean 130 Crore Litres of Air Per Day!

Kurin Systems has designed a 40-feet-tall purifier christened ‘City Cleaner’, which claims to provide clean air to 75,000 people living in the 3-km radius around it.

The National Capital is gasping for air. And with the festive season here, the air quality continues to degrade from worse to severe.

In this grim scenario, a Delhi-start-up’s innovation could spell relief for its people.

Speaking to PTI, co-founder Pavneet Singh Puri revealed that the company’s patent for the “world’s largest as well as the strongest air purifier” has been published by the World Intellectual Property Organisation.

Here’s all you need to know about it:

  • The purifier which will be 40-feet tall and 20-feet wide, will have the capacity of cleaning 32 million cubic metres of air per day.
  • Designed on the air quality of the capital, one such purifier will be able to provide clean air in the 3-km radius of its location, impacting about 75,000 lives, said Puri.
  • The purifier will take air from all angles, which in turn, will help generate 13,00,000 cubic metres of clean air per hour.
  • The Kurin City Cleaner will work using nine stages of physical filters to clean out 99.99 per cent pollutants. Apart from the pre-filter which will remove the visible (Particulate Matter 10 & above) particles; H14 grade HEPA filter (Highly Effective Particulate Arrestance) will clean out PM 2.5 particle (small particles) up to 99.99 per cent.
  • The activated carbon filter will remove all offset, volatile organic compounds (VOCs) and scents/smells, added Puri.
  • The tower will also be equipped with as many as 48 fans to keep the flow of clean air constant.
  • The air-purifier will skip the electric grid and run on solar energy, provided there is adequate space. Thus making it cost-effective and environment-friendly.

“China has already witnessed huge success with their Smog Tower in Xian which has been successfully able to clean 10 million cubic metres of air daily. But our product will be to clean three times of that number,” he claimed.

What then is the difference between the City Cleaner and the Xian Smog Tower?

Delhi’s City Cleaner will be different from China’s Smog Tower as it wouldn’t use the ionisation technique to clean the air.

“The ionisation of air does not eradicate the pollutants but works by separating the pollutants from the oxygen, which could be a part of the problem itself,” Puri explained.

Hope for Delhi

While a section of citizens is privileged to afford air-purifiers at home, the City Cleaner will come as a relief for those who can’t.

Puri added that the tower would take four months to be completed after it receives the required approvals from the authorities.

The estimated cost of the purifier per tower is between Rs 1.75-2 crores.

“Not only is our device cheaper than existing devices being used in other parts of the world which cost around USD 300,000 (but) it also cleans many more times than the ionisation towers,” Puri told PTI.

The team has been pitching the idea of city-level air cleaning to central as well as state governments.

The co-founder added that the company tested the technology in one of their at-home devices before filing the patent.

“We created a six-foot-tall model using the core technology and found out that it works great. To be doubly sure, we gave samples to hospitals, veterinarians, commercial spaces and to people living around Anand Vihar and in Ghaziabad to test out the device in the toughest situations,” Puri shared.

Madhur Mehta, Co-Founder, Kurin Systems, noted how the innovation could spell hope for Delhi, saying, “We wish to show how tremendously effective this technology can be, if used before things get out of hand. We can still save this city and this country and most importantly, countless lives.”
