Half of India’s urban populations breathes air laced with particulate pollution that has exceeded standards. A High one-third of our population is exposed to critical levels of Air Pollution.
Air purifiers have HEPA (high efficiency particulate air) filters that aid in cleaning the air around that is circulated. They help get rid off contaminants and impurities from the air. It is possible for the HEPA filter to remove about 99.9% of dust particles bigger than 0.3 microns (the standard measure of microns).
