June 5th is World Environment Day initiated by the United Nations. Since its establishment in 1974, World Environment Day has developed into the world's largest environmental event and is an important platform for advocating environmental action.

The theme of this year's World Environment Day is "air pollution". For many years, air pollution has been a top priority on the global agenda, but it is not actually a new issue. Scientists have recently found that humans are responsible for at least the continuous increase in air pollution over the past 2100 years by extracting ice layers that have accumulated on Greenland for thousands of years and analyzing methane in them.

Although humans have caused more environmental pollution in recent decades, people's knowledge has also multiplied and they have become aware of the severity of pollution. Environmental organizations, scientists, governments, world leaders, and industry leaders are all working hard to make changes and reverse this trend, and Clearlist is one of them.

Since its establishment in 1969, the British oil mist filter brand Clearmist has been committed to manufacturing and developing sophisticated oil mist filtration equipment, helping global manufacturers improve workshop air and create clean and efficient production environments.

During the half century of Clearlist's operation, the company has witnessed tremendous development in this industry. However, there are still some regions in the world where the pollution level is far higher than the acceptable level stipulated by law, and there are still some individuals and employers who have not fully understood the severity of air pollution and the negative impact of pollutants such as oil mist and dust.

Air pollution refers to the pollution caused to indoor or outdoor environments by any chemical, physical, or biological substances that can alter the natural characteristics of the air. Excessive pollution can have an impact on the environment, such as the well-known global temperature rise; It can also cause harm to human health and lead to diseases.

The pollutants in the atmosphere include carbon monoxide, sulfur dioxide, and particulate matter (PM), among others. Among them, particulate matter includes oil mist particles that are produced during metal processing in various industries. According to the different particle sizes, particulate matter can be divided into different categories: PM10 is classified as less than 10 μ The particle composition of m can enter the lungs upon inhalation; PM2.5 can penetrate the gas exchange area of the lungs and enter the bloodstream.

The use of oil mist filters is an effective way to reduce oil mist particle pollution. Installing an oil mist filter on the machine tool can ensure that the air contaminated by the oil mist is sucked away at the source. Then, under the impact of centrifugal force, the oil mist particles are filtered, and clean air can be returned to the workshop through the top of the filter. This greatly reduces the possibility of polluted air spreading into the workshop, while protecting workers from the impact of harmful air particles and improving enterprise productivity.

Since the 1970s, under stricter regulations, the PM2.5 pollution in most countries around the world has decreased. However, some countries, including India, China, and Greece, have shown a trend of PM2.5 growth due to rapid industrialization.

According to climate change scientists, we only have 11 years left before it's too late to try to reverse the impact of global warming. Many global movements have emerged to raise people's awareness of air pollution and take action to reduce these levels, and the 2030 Breath Life Plan is one of them. According to Breathing Life, 1.94 million deaths in China each year are related to air pollution, with PM2.5 concentrations in Shanghai and Kunshan being 4.5 and 4.6 times the recommended safe levels, respectively. Effectively filtering particles and reducing pollution emissions are measures that every enterprise should consider taking.
