Description

TITLE: AN AIR PURIFIER DEVICE
FIELD OF INVENTION:
The invention relates to an air purifying device. More particularly it relates to a device which improves the air quality index value.
BACKGROUND OF THE INVENTION:
Air Quality Index (AQI) is a standard value which generally measures the amount of acidic oxide such as (CO)x (NO)x, (SO)x and particulate matter which are unhealthy and a big concern in recent times. If air has low value of AQI then the air is termed as healthy whereas air with high AQI is considered as health hazards. Because when AQI values are above 100 ppm, air quality is considered to be unhealthy, especially for members of populations at greatest risk of a health effect, such as person having asthma, bronchitis and other breathing issues. It is not safe for entire population as if AQI values gets higher (greater than 200ppm).
In 2018, the World Health Organization (WHO) estimated that about 7 million people die each year as a result of breathing tiny particles in contaminated air. In addition, diseases including stroke, heart disease, lung cancer, chronic obstructive pulmonary disease, and respiratory infections including pneumonia develop. According to the WHO, air pollution kills about 700,000 children each year.
Vehicle and industrial pollution are the most common causes of air pollutants, and both are connected to climate change, consequently it indicates that global warming is affecting around the globe.
Every year during the winter season, harvested leftover crops’ burning produces a blackout in the northern region of our country. It was the first thought, but after profound study of the surroundings, it was determined that it was fossil fuel, which is also a by-product of plants and animals. CO, CO2, SO2, NO, NO2 at very high concentrations are the end result of combustion. It also causes a large number of particles to get suspended in the air. All of these issues together implicate that innovation is taking shape.
The seriousness of the issue can be seen from the below data:
Figure imgf000004_0001
Air purifiers have been developed to remove the health risks associated with poor air quality. Currently, a big smog-towers have been installed in few of the cities of India.

While working on air pollution they contribute to noise pollution. Thus, there was a need of a system or device which will reduce the air pollutants and improve the air quality index of surrounding air. Current invention fulfils this need. Rapidly rising pollution levels and an increase in airborne illnesses are the primary reasons of developing the current invention. It’s a device which will not require any special set-up to install as in case of the smog-towers. It is a cost effective and silent device.
