One of my cousins installed an air purifier in his house. He stated that he turns it on for a few hours each day, as he does not want to get used to it. He thinks that normal/natural air is the best.
It is right that natural air is the best. However, is this natural air the same as it used to be years back? Pollution, as well as deforestation, is increasing. People are planting fewer trees and cutting more. In addition, ventilation in houses/buildings is not optimal.
If pollution is artificial and natural air purifiers are disappearing then don't we need artificial air purifiers?
