“…Air purifiers are high-tech devices that clean the indoor air by removing impurities such as dust particles (including PM 2.5 particles—the tiny particulate matter that causes the most damage to human health), pollen, smoke and other airborne irritants. Their aim is to typically provide uncontaminated air, though many companies also claim that their purifiers reduce allergic reactions and asthma attacks….But here’s the problem: No one’s quite sure about how much of an impact these purifiers have. While doctors and medical experts agree that these machines could provide people with clean air, they are unsure whether air purifiers actually help in controlling the incidents of respiratory attacks among those who are prone to such diseases.” Quartz India.
