In a city like Delhi, which is, according to a World Health Organization (WHO) report, the most polluted in the country, air purifiers are almost a mandate for leading a healthy life. Not always can we expect our surroundings to be dust-free and residents who live close to the port and on the highways, tend to suffer the most from pollution and contaminated air.
The fundamental purpose solved by an air purifier is removing the contaminants from the air in a room. As a result, people who suffer from asthma and other allergies, can feel a lot more at peace with a room or home air purifier in place than without it.
Although people with allergies tend to benefit the most from air purifiers, air purifiers can be used by anyone to lead a healthy life. The principle by which air purifiers work, varies: some are based on thermodynamic sterilization, some on ultraviolet germicidal irradiation, some on the basis of photocatalytic oxidation, etc.
