This Rs 10 Device May Help You Tackle Pollution


New Delhi: As the air quality in the national capital continued to worsen every day, putting residents at high risk of respiratory problems, Nasofilters – a revolutionary respiratory filter – developed by a team of researchers from Indian Institute of Technology-Delhi (IIT-Delhi), in collaboration with Nanoclean Global Private Ltd, may help tackle air pollutants that go into your nostrils.

As per reports, the product costing just Rs 10 and designed to protect users from air pollutants, including PM 2.5 particles will be available for purchase from Tuesday.

The device, which will initially be available online before it hits retail shops, received the ‘Startup National Award’ 2017 by former President Pranab Mukherjee. It also made it to the South Korean government’s list of ‘Top 50 technical startups in the world’.

“From tomorrow (Tuesday), the filters will be available on our website After a few days, we will make them available on all recognised e-commerce websites, and finally in retail shops. We hope to start physical sale in January. It would come in the box of 10 nasofilters initially. Subsequently, we will also introduce a box of 30,” said Prateek Sharma, chief executive officer of Nanoclean Global Private Ltd, the company which was incubated at IIT-Delhi to produce the filters.

The filters can stick to the user’s nasal orifice and restrict foreign particulate matter from entering the body, and at the same time gives very little pressure drop, which makes it unique. It is a use-and-throw biodegradable product.

The inventors said the filters, which can last up to 8-10 hours, can keep away PM 10 particles by 100 percent, and PM 2.5 particles by 95 percent.

The air quality in Delhi reached ‘severe-plus or emergency’ levels on Monday, which turned out to be worst air quality on New Year’s day in the past two years.

On Monday, the average air quality index (AQI) of Delhi was at 400, considered severe. According to System of Air Quality and Weather Forecasting And Research (SAFAR), the air quality is set to deteriorate further on Tuesday, however, it will get better after three days.
