| | APRIL 20208Air pollution has become one of the major issues in today's climate, and accord-ing to the World Health Organ-isation, more than four million people die early because of the in-creasing level of pollution in the air. While we are only concerned about outdoor air pollution, we often forget that indoor air pollu-tion is equally harmful as outdoor air pollution. The fine particles in the air can penetrate deep into the lungs, heart and bloodstream, where they cause various diseases and cancer. As per established ventilation guidelines, indoor Carbon Diox-ide (CO2) levels must not be more than 650 ppm than the local out-door concentration. Hence, it's necessary to protect yourself and your family from toxic air. Not just home, even industries should install air purifiers to protect the health and well-being of their pa-trons and employees, as the air quality is worsening daily.An air purifier is an electron-ic device that removes pollutants, odour, smoke, and other invisible yet harmful substances & gas-es that pollute the air in order to make the air clean and breath-able. This device is efficient and built to combat air pollution, at least in closed spaces like offices, and homes. However, you need to be careful while choosing an air purifier, as not all devices are ef-fective. Here are a few important elements you must know before purchasing an air purifier:Air Change Rate (ACR) & Clean Air Delivery Rate (CADR)Air Change Rate is the number of times a purifier cleans the room air in an hour. Therefore, high-er air change rate will clean the entire room faster. In addition to ACR, one should also look at CADR. Clean Air Delivery Rate is the quantity of clean air that the air purifier pumps-out and is mea-sured in cubic feet per minute.
