Air pollution is one of the most serious environmental problems facing the world today. It is mainly caused by industrial activities, transportation, and the burning of fossil fuels. This pollution leads to severe health issues such as respiratory and cardiovascular diseases, in addition to its negative impact on the climate. Therefore, modern technologies have been developed to purify air and reduce pollutants before they spread into the atmosphere. One of the most important methods is the use of industrial filters that trap fine particles and harmful gases. Chemical absorption systems are also used to remove toxic gases such as sulfur oxides and nitrogen oxides. Electrostatic precipitators are widely used in factories to capture very fine particles produced during combustion processes, significantly reducing harmful emissions. In addition, technological advancements have improved the efficiency of these systems, making them more effective and energy-efficient. Alongside technical solutions, environmental regulations play an important role in forcing industries to comply with emission standards, which helps improve overall air quality. In conclusion, air purification technologies are essential for protecting both the environment and human health. Continuous development of these systems is necessary to address increasing environmental challenges.
