The industrialized world has brought tremendous changes to our humanity. Severe pollution is one of the changes that affect the environment. Today, air pollution has become a global problem, the severity of which varies from place to place. In view of the fact that the impact on human health is mostly manifested over time, this problem is often overlooked. The World Health Organization (WHO) points out that nearly 2 million people die each year from air pollution.
Outdoor pollution penetrates into houses and buildings and can easily lead to indoor pollution. Effective filtration solutions can cleanse the air and protect human health, but few people know that clean air can also increase productivity and control costs. It takes money to protect human health from the effects of air pollution. For example, this long-term investment can also reduce the losses caused by high sick leave rates at work and reduce related medical expenses. Large-scale scientific research conducted in Scandinavia has shown that improved ventilation conditions have improved the learning efficiency of school children by 15%.
