Air pollution can increase the risk of several respiratory infections, heart disease, stroke, lung cancer and many other health problems.
According to the Global Air Quality Index, the air quality in Delhi reached dangerous levels in June of this year, the national capital registering a value of the index air quality (composite measure of pollution by ozone, nitrogen dioxide, sulfur dioxide and particulates) of 999.
Experts say that exposure to high levels of air pollutants increases the risk of respiratory infections, heart disease, stroke, lung cancer and many other health problems. The alarming levels of air pollution in India, however, have also represented an important market opportunity for global brands. Actors such as Honeywell, Daikin, Panasonic and many others have entered the Indian market with their anti-pollution offers.
Start-ups have also come up with innovative ideas for combating air pollution and proposing solutions at different levels. Here are a few.
Phoenix Robotix
This The Odisha-based IoT startup has designed Aurassure, an environmental monitoring device. It's a cloud network of online air pollution monitoring systems for smart cities. Through the network, industries can access high-resolution pollution data "via a hardware-integrated software platform."
The device captures various air quality settings from different locations and stores them on a web platform. The data can be viewed via a mobile application. Some of the recorded parameters are nitrogen dioxide (NO2), nitrogen monoxide (NO), ozone (O3), methane (CH4), ammonia (NH3) , PM2.5, PM10, UV, meteorological parameters such as temperature, humidity, precipitation, etc. pressure, speed and direction of the wind. To make it compatible with smart cities, the device is compatible with Ethernet, GPRS, wifi and LoRa.
The company says the "portable solution" can be rolled out to schools, colleges, hospitals and research institutes to raise awareness of air quality. This device can also be useful in agriculture, because the recorded data can be used by farmers to improve irrigation and take measures to protect crops against climatic hazards. It also has an urban flood monitoring system capable of tracking water levels in canals and rivers.
Phoenix Robotix, founded in 2015, is spearheading six NIT Rourkela engineers – Amiya Kumar Samantaray, Kishan Kumar Patel, Akansha Priyadarshini, Asish Sahoo, Nataraj Sahoo and Ashutosha Sarangi.
Shellios
Shellios, a startup based in Delhi, is testing a user-friendly solution for bikers that will help combat air pollution. The company has designed a 1.6 kg helmet with an integrated air purifier and is currently testing it.
There are lots of innovations on air pollution measuring devices, but Shellios go a little further. The purifier filters the air so that the rider can breathe. It also comes with a Bluetooth-enabled application that allows the rider to know when the helmet needs to be cleaned.
The indoor cleaning function runs on a battery operated module, carrying a 2600 mAh unit. A micro-USB port can be used to charge the battery. In addition, the leather padding and protective layers on the helmet are detachable, making it easy to clean the parts.
Chakr innovation
Founded by IIT-Delhi graduates Arpit Dhupar, Kushagra Srivastava and Prateek Sachan in 2016, Chakr innovation converts diesel soot from generators into inks and paints.
Chakr Shield works on a solvent-based method. he collects about 90% of particulate emissions, which are essentially black carbon. The emission is then subjected to various proprietary processes to remove heavy metals and carcinogens. (substances or agents that can cause cancer). It is then converted into a purified carbon-based pigment. In the last stage, carbon undergoes another chemical process to make different types of inks and paints, thus ensuring that pollutants are disposed of in the most environmentally friendly way.
The technology claims to capture over 90% of particulate emissions from diesel generator exhaust without causing any negative impact on the diesel engine.
In a previous interview with YourStory, Kushagra said, "We are also in talks with several industrial houses, IT companies, hotel complexes and public sector companies for our product. The ink we manufacture against pollution is used by a major computer manufacturer to print their packaging in India. Until now, there are 35 sites using Chakr Shield in the NCR of Delhi, in sectors such as telecoms, consumer products, real estate, educational institutions and well d & # 39; others. "
Nasofilters
The nasal filter is sold by the Nanoclean company, based in Delhi. It was founded by a team from IIT-Delhi – Prateek Sharma, Tushar Vyas and Jatin Kewlani in 2017.
At only 10 Rs, this nasal filter can limit the penetration of harmful particles when you inhale. The company claims that the filter has a 95% efficiency rate by blocking PM2.5. Particles are a mixture of tiny particles lodged in liquid droplets in the atmosphere. PM2.5 can cause respiratory and cardiac conditions when they are lodged in the lungs.
Nasofilters use nanotechnology to minimize breathing difficulties. The team created nanofibers by reducing the wire diameter of a normal tissue 100 times in order to filter pollutants.
Unlike other traditional options (face masks) available on the market, this does not restrict breathing because it can simply be worn on the nostrils.. A nasofilter can be used for 12 hours and is intended for single use.
These are available on the company's website, at Amazon pharmacy, Flipkart, Snapdeal, Paytm and Apollo stores in Delhi.
They also claim to protect themselves from dust and pollen, helping asthmatic and allergic patients. (pollens are bigger than PM2.5)
Parsapien
Launched in 2017, Airlens, a portable nasal garment, was developed by a team of IIT scientists – Professor Padmashri Randeep Guleria (Director of AIIMS) and Professor Paul Yock (father of Biodesign, Stanford University), and the Shashi Ranjan team, Debayan Saha, Yogesh Agarwal, Akanksha Gupta and Harsh Sheth. It is sold under the company PerSapiens. The portable nasal is a product to use and discard and does not require cleaning. It limits the entry of pollutants into the lungs, requires no attachments and measures just 2 cm.
The laptop is supported by an app that helps to assess the degree of protection needed. The startup's air quality data system provides real-time air quality data in the immediate area (within 1 km). Its technology uses "satellite, meteorological and traffic data with advanced models to provide accurate data on air quality" for user location.
Once the application suggests when to use the laptop and how long to use it, one can wear accordingly and track their progress on it. The device is available on Amazon and on their website at the introductory price of Rs 347 for children and adults. The Airlens Data app, by contrast, is free.
