Geneva – The World Health Organization (WHO) publishes the latest Ambient air pollution (A global assessment of exposure and burden of disease). According to the WHO’s new air quality model, 92% of the world’s population lives in areas where air quality levels exceed WHO limits. The information is presented through an interactive map that highlights areas within the country that exceed WHO limits. ‘The new WHO model shows countries where there is a risk of air pollution, and a baseline is provided to help monitor progress in controlling pollution,’ said Dr. Flavia Bustreo, Assistant Director-General of WHO.

This model also reflects the most detailed outdoor (or environmental) air pollution-related health data reported by WHO in the countries. Developed in collaboration with the University of Bath, the model is based on satellite measurements, atmospheric transport models and ground station monitors covering more than 3,000 urban and rural locations.

The cost of air pollution to human health

  • About 3 million deaths each year are associated with exposure to outdoor air pollution. Indoor air pollution can also be fatal. In 2012, an estimated 6.5 million deaths (11.6% of the world’s total deaths) were related to indoor and outdoor air pollution.
  • Nearly 90% of air pollution-related deaths occur in low- and middle-income countries, and nearly two-thirds are in the WHO South-East Asia Region and the Western Pacific Region.
  • 94% are caused by non-communicable diseases, especially cardiovascular disease, stroke, chronic obstructive pulmonary disease and lung cancer. Air pollution also increases the risk of serious acute respiratory infections.
  • ‘Air pollution continues to pose a health penalty for the most vulnerable people (women, children and the elderly),’ Dr. Bustreo added. ‘People want to be healthy, they must breathe fresh air from birth until the last moment of life.’
  • The main sources of air pollution include inefficient transportation, domestic fuel and waste incineration, coal-fired power plants and industrial activities. However, not all air pollution comes from human activities. For example, air quality can also be affected by sandstorms, especially in areas close to the desert.

Important fact

  • Air pollution is a major environmental risk affecting health. By reducing air pollution levels, countries can reduce the burden of disease caused by stroke, heart disease, lung cancer, and chronic and acute respiratory diseases, including asthma.
  • The lower the level of air pollution, the better the cardiovascular and respiratory health of the population, both long-term and short-term.
  • The WHO Air Quality Guidelines assess the health impacts of air pollution and pollution thresholds that are harmful to health.
  • In 2014, 92% of the world’s population lived in places that did not meet WHO’s air quality guidelines.
  • In 2012, environmental (outdoor) air pollution in urban and rural areas is estimated to cause 3 million premature deaths worldwide.
  • About 88% of these premature deaths occur in low- and middle-income countries, with the largest burden in the WHO West Pacific and South-East Asia regions.
  • Implement policies and invest in support for cleaner vehicles, cleaner energy-efficient homes, cleaner power generation, cleaner industries, and better urban waste management to reduce the main sources of outdoor air pollution in cities.
  • Reducing outdoor emissions from domestic coal and biomass energy systems, agricultural waste incineration, forest fires and certain agroforestry activities (such as charcoal production) can reduce major air pollution sources in rural and suburban areas of developing regions.
  • Reducing outdoor air pollution also reduces carbon dioxide and emissions of short-lived climate pollutants such as black carbon particles and methane, thereby helping to mitigate climate change in the near and long term.
  • In addition to outdoor air pollution, indoor smoke is also a serious health risk factor for approximately 3 billion people who use biomass fuel and coal for cooking.

To solve indoor pollution, how big is the role of the air purifier?

It is undeniable that industrialization has covered most of the world. However, with the advancement of human society, the development of science and technology, the destruction of the living environment has reached the red line. For example, the reduction of forests, rising sea levels, etc. have endangered human life. Then the decline in air quality during these crises has undoubtedly caused great harm and inconvenience to our lives.

In this environment, the air purifiers that emerged as the times have become the main means and important means for us to improve and control air quality. The air purifier is a nemesis of indoor air pollution. It is an indoor ‘360 health guard’. The ability to resist indoor pollutants makes it trust people, but there are still people asking, is the air purifier useful? Let’s discuss this issue below.

As one of the most basic substances for the development of life and health, air has a huge impact on life. In the context of the pollution of the environment and the sharp decline in air quality, and the increasing amount of indoor pollutants, air purification Can the device really improve our breathing quality? Of course, the air purifier is not a large ambient air purifier. The environment that can improve the air quality is limited to the indoor space. Some people will question whether the indoor air is the safest place. Is the air polluted? But you can’t underestimate, because indoors are not only affected by air pollution in the big environment, such as car exhaust, garbage smell, factory exhaust, etc., as well as the destruction of various indoor pollutants, such as formaldehyde, tovc, Pathogens, etc. However, according to incomplete statistics, about two-thirds of people spend a day in indoor space. Therefore, indoor air quality is seriously damaged by people’s health, so we will not be polluted indoors. Do not give more explanation for the time being.

However, how does the air purifier clean the indoor pollutants and how to cover the indoor air quality? The air purifier, also known as the air purifier, is composed of fan power, filter net and various purification technologies. The air purifier combines these main constituent elements scientifically and effectively to clean up the pollutants in the indoor air. And purification, which is why air purifiers have such a skill. Next we will talk about the purification of air purifiers.

The HEPA filter is made of laminated antimicrobial peptide PP fiber, which, like paper, is capable of absorbing 99.7% of suspended particles of 0.3 micron size (0.3 micron is the most difficult to filter).

Activated carbon filter Activated carbon is an internationally recognized high-efficiency adsorption material. Activated carbon is a porous carbonaceous material. Its developed void structure makes it have a large surface area, so it is easy to be fully toxic with harmful gases in the air. Contact, a strong adsorption field around the activated carbon hole will immediately inhale the toxic gas molecules into the pores, so the active carbon has a strong adsorption capacity is also the main technology to remove gaseous pollutants.

UV disinfection is widely used. It can purify the air and eliminate the musty smell. In addition, it can produce a certain amount of negative oxygen ions. The room is especially fresh after being disinfected by ultraviolet light.

Negative ions are formed by the combination of free electrons in the oxygen molecules in the air. Negative oxygen ions enjoy the reputation of ‘vitamin’, ‘air vitamin’, ‘longevit’, ‘air vitamin’ in the medical world, and the use of air purifiers. Negative ion purification technology can further improve the quality of indoor air.

The above is the common purification technology in the air purifier. With such a purification method, it is a nightmare for various pollutants in the air, and it is a dream for human health. Therefore, in the face of the huge trauma caused by indoor air pollution, the choice of air purifier is the best choice.

In the summer, do we need an air purifier?

When it comes to summer, the image that people often have in their hearts is a clear sky or a fresh and cool shower, but rarely sees the occurrence of fog. So in many cases we simply judge from our senses that the air purifier seems to be dispensable in the summer. So in the summer, do we need an air purifier? The answer is yes!

First of all, the air purifier is not just for preventing smog

In the summer, smog is rare, even if it is not as polluted as winter, so most consumers will not turn on the air purifier. In fact, although the severity of haze in summer is much lower than in winter, other types of indoor pollutants are much higher than in winter. It is understood that the release of indoor pollution such as formaldehyde is greatly affected by temperature, especially in summer, which will accelerate their release. Because the air purifier is not only used to combat PM2.5 pollution, it also has a variety of effects such as removal of VOC (volatile organic compounds), removal of pathogenic bacteria and allergens.

Secondly, the air purifier can effectively prevent air-conditioning diseases.

When summer arrives, it is inevitable to close the doors and windows to open the air conditioner, but some people will suffer from “air conditioning disease” when they have been air-conditioned for a long time. It is understood that air conditioners use water when they work, and water can form a series of pollutants such as aerosols with some granular materials. Since the doors and windows need to be closed when the air conditioner is turned on, the pollutants can only be circulated indoors, and the air quality is inevitable. If an air purifier is used in combination, fine particles, volatile organic compounds and bacteria in the air can be removed, thereby effectively preventing air-conditioning diseases.

Finally, the negative ion air purifier can purify the air and health care

The negative ion air purifier can generate small-sized, high-activity ecological-grade negative ions equivalent to nature. The ecological grade negative ion is a small particle size negative ion with small particle size, which has the characteristics of high activity and long natural diffusion distance. It releases the small particle size particles in the air by releasing small particle size negative oxygen ions and performs agglomeration and sedimentation to achieve the effect of air purification.

Through the above analysis, we also need air purifiers in the summer to create a good environment for the families we live in. Therefore, in the summer when the haze is not serious, we should not only turn off the air purifier, but keep it in a normally open state.
