This IIT-Delhi Startup’s Innovation Tackles Air Pollution for Just Rs 10!

Did you know air pollution kills an estimated seven million people worldwide every year? According to the World Health Organisation (WHO) data, nine out of 10 people breathe air containing high levels of pollutants.

Closer home, in June 2019, a report by an environmental organisation, Centre for Science and Environment (CSE), stipulated that life expectancy in India has gone down by 2.6 years due to the deadly diseases caused by air pollution. The third highest cause of death, ranking just above smoking in India, is the combined effect of outdoor particulate matter (PM) 2.5, ozone and household air pollution.
But what if we told you that a low-cost invisible nasal filter that sticks on your nasal orifice could prevent dust and air pollutants, especially PM 2.5 from entering your system?

 

Or that a Rs 400 filter could turn your AC into an air purifier?

Or that a pollution net fixed on your doors and windows could not only stop dust and pollutants but also protect your home from harmful UV rays?

Shocked?

Meet Prateek Sharma, an IIT-Delhi alumnus who with a dream team consisting of fellow IIITians, Tushar Vyas and Jatin Kewlani, supported by faculty members, Prof Ashwini Agrawal and Prof Manjeet Jassal, established award-winning startup, Nanoclean Global Private Limited. A startup that has been developing low-cost preventive measures for polluted air and innovations for air filtration.

Nanoclean was awarded the National Startups Award by former President Pranab Mukherjee in 2017, recognised among the top 25 technical startups from over 118 countries by the Republic of Korea and selected among Top 100 Startups in the World by the Hong Kong government, making it the only Indian startup to achieve this feat.

Who is Prateek Sharma?

 

Born in Jaipur and raised in Bikaner, Rajasthan, Prateek Sharma had grown up watching his own mother, an asthmatic, struggle with both indoor and outdoor pollution and sand storms, a common phenomenon in the desert state.

“It ached me to always see her cover her mouth with a dupatta when she walked outside. Growing up, I would either alter existing masks in the markets or gift her different types of equipment like nose-insertion buds. But nothing seemed to work. She refused to wear a mask stating that people would think she is sick if she stepped out with it and the nose-insertion buds created a lot of discomfort.”

Today, the innovative nasal filter that his team has developed, christened ‘Nasofilter’, costing close to Rs 10 a piece, is protecting people in 30 countries against air pollutants.

 

What is Nasofilter?

Launched as one of the first commercial products by the startup which was incubated at IIT-Delhi, it is a respiratory filter that restricts the entry of dust and tiny suspended particulate matter from entering your system while breathing.

Particulate matter refers to the microscopic solid particles and liquid droplets floating in the atmosphere. Fine (PM2.5) and coarse (PM10) particles are considered to be the most hazardous pollutants.

Nasofilter uses nanotechnology to create nanofibres by reducing the thread diameter of a normal fabric by 100 times, creating millions of pores in a tiny area to filter out pollutants.

The resulting device can combat 90 per cent PM2.5 and 95 per cent PM10 particles.

What is its USP?

  • It is small and easy to wear biodegradable polymer. In stark contrast to large traditional face masks, it is a transparent filter that covers your nostrils, is invisible from a distance and can be worn for up to 24 hours.
  • It filters out PM2.5 and other air pollutants
  • Does not restrict breathing or speaking
  • It is also one of the cheapest options available in the market.
  • The team was able to successfully patent the technology behind the innovation two months ago.

Another product that the founders worked on is aimed to combat indoor air pollution. This refers to the Nanoclean AC filters.

 

 

Costing as low as Rs 400, this device has been designed to complement existing filtering screens of wall-mounted air conditioners. Simply put, it converts your AC into an air purifier at no recurring electricity cost, using nanotechnology.

It removes PM2.5 and other Micro-Particle pollutants from the air inside homes while cooling it at an affordable cost.

Features:

  • It can purify the air from various pollutants such as PM 2.5, dust, allergens, etc inside a room by 90 per cent within the short span of one hour
  • It is compatible with both window & split ACs
  • It has no recurrent electricity costs
  • It does not affect cooling or increase power consumption.
  • It is easy to install and you change its filter by yourself.
  • Even though one filter can last for two months, for best results, it is recommended to change it every month.

Indoor air pollution is considered 10 times worse than outdoor air pollution due to the potential of contained spaces to allow pollutants to build up more in our system than open spaces. And while major cases are often seen in rural areas owing to use of chulhas and firewood, indoor pollution is also witnessing a steady rise in leading cities.

 

And so for those who do not have ACs at home but want to combat indoor pollution, the innovators have also developed the ‘Nasofilters Pollution Net.’

 

Designed to replace your mosquito net on existing doors and windows, it allows your home to be free of PM 2.5 & 10 particles, dust, UV rays, and allergens.

The outer layer of the net is a hydrophobic mesh, which repels water and makes it water-resistant.

It is a three-structured net, while the first layer is designed to fit the net in existing moulds of your doors and windows, another white layer ensures water resistance and provides protection from harmful UV rays. Sandwiched between the two layers is the nanofiber layer which filters PM 2.5 PM matter

With durability of up to five years, unlike the AC filter which needs to be replaced every month, the pollution net can be easily cleaned with a damp cloth.

Currently selling in the Indian market at Rs 200 per sq feet, the cost of installing the pollution net on all doors and windows of a 2BHK home may come up to 7,000-8,000, says Prateek. The product which is currently being sold in the B2B market has received positive feedback and testimonials from builders and architects, adds the co-founder.
