DESC:Air Pollution in India is a serious health issue. As per a study based on 2016 data, at least 140 million people in India breathe air that us 10 times or more over the WHO safe limit and 13 of the world's 20 cities with the highest annual levels of air pollution are in India. Air pollution contributes to the premature deaths of 2 million Indians every year. In urban areas, most emissions come from vehicles and industry, whereasin rural areas, much of the pollution stems from biomass burning for cooking and keeping warm. In autumn and winter months, large scale crop residue burning in agriculture fields – a low cost alternative to mechanical tilling – is a major source of smoke, smog and particulate pollution. India has a low per capita emissions of greenhouse gases but the country as a whole is the third largest after China and the United States. A 2013 study on non-smokers has found that Indians have 30% lower lung function compared to Europeans. The Air (Prevention and Control of Pollution) Act passed in 1981 to regulate air pollution but has failed to reduce pollution because of poor enforcement of the rules. In 2015, Government of India, together with IIT Kanpur launched the National Air Quality Index. In 2019, India launched 'The National Clean Air Programme with tentative national target of 20%-30% reduction in PM2.5 and PM10 concentrations by 2024, considering 2017 as the base year for comparison. It will be rolled out in 102 cities that are considered to have air quality worse than the National Ambient Air Quality Standards.

Health costs of air pollution

The most important reason for concern over the worsening air pollution in the country is its effect on the health of individuals. Exposure to particulate matter for a long time can lead to respiratory and cardiovascular diseases such as asthma, bronchitis, COPD, lung cancer and heart attack. The Global Burden of Disease Study for 2010, published in 2013, had found that outdoor air pollution was the fifth-largest killer in India and around 620,000 early deaths occurred from air pollution-related diseases in 2010.According to a WHO study, 13 of the 20 most-polluted cities in the world are in India; however, the accuracy and methodology of the WHO study was questioned by the Government of India. India also has one of the highest number of COPD patients and the highest number of deaths due to COPD. Over a million Indians die prematurely every year due to air pollution, according to the non-profit Health Effects Institute. Over two million children 8 -- half the children in Delhi -- have abnormalities in their lung function, according to the Delhi Heart and Lung Institute. Over the past decade air pollution has increased in India significantly. Asthma is the most common health problem faced by Indians and it accounts for more than half of the health issues caused by air pollution ,CLAIMS:CLAIM 1:

Integration of suction fans, pipes and tunnels to the .

1. Pipes and Tunnels:

A large network of huge pipes to be installed at various points in the city, which will be connected to the Tunnels passing through the main areas of the city. These networks of pipes and tunnels will be used to carry the polluted air to the gigantic air purifiers.

2. Suction fans:

Suction fans will be used to suck in the polluted air from the local area where it’ll be installed. These sucked in polluted air will be passed on to the above mentioned Pipes and tunnels.

CLAIM2:

Algorithm used for efficient air flow.

The flowchart solves the problem of optimising the entire system by calculating and implementing the individual fan speeds to each suction fan such that the air entering the air purifier is synchronous to the speed at which the air purifier can purify.
