Abstract

The air purifier industry has
seen a growth in terms of demand and sales lately. All credit goes to massive
industrialization in developing countries such as India and China. As a result,
a lot of research has been focused into the various methods of purifying air.
The most harmful of the pollutants are PM 2.5 particulates and NOx emissions.
The aim has been to bring down the costs without compromising on efficiency as
efficient air purification is an expensive deal. This article presents a study
of the current scenario of the problems of air pollution. Severity of the
issues have been highlighted. A compilation of the most common and significant
methods of purifying air such as those employing the use of HEPA filters,
electrostatic smoke precipitators, activated carbon and UV light has been
presented and their use in air purifiers manufactured by OEMs has been
mentioned. Some of the most modern methods of purifying air such as those using
transparent PAN filters, photochemical materials, soy proteins and silk
nanofibrils have been studied and reviewed. It has been found that these
methods provide an attractive and economical pathway of filtering out PM 2.5
when compared to the conventional HEPA filters.
