Currently, environmental pollution is at an alarming level. Therefore, overcoming the situation of fine dust plays an important role in protecting human health and the living environment.
1. Fine dust PM 2.5
PM 2.5 fine dust is known to be a complex mixture of many inorganic and organic particles in liquid or solid form. And this mixture has the ability to float in the air. These airborne fine particles can vary in shape, composition, and characteristics. Dust particles are quite small in size and can only be detected with a microscope.The best known microscopic particles ( microns ) are:
PM10: Fine dust with a diameter of 2.5 to 10 microns the size of a millionth of a meter. PM2.5: Fine dust less than 2.5 microns in diameter. PM1.0: Ultra-fine dust with a size of 1 micron. PM0.1 nano dust: Ultra-fine dust less than 0.1 micron in size. PM2.5 fine dust is tiny dust particles present in the air with a size of 2.5 microns or less (about 30 times smaller than a human hair).
2. Harm of PM 2.5 fine dust on human health
PM 2.5 fine dust particles are known as silent killers. The level of danger of fine dust will depend on the size of the dust. However, PM 2.5 dust particles are quite small in size and can enter and get stuck in the nose, mouth, and upper respiratory tract. Therefore, it will increase the risk of acquiring or aggravating respiratory-related diseases such as allergic rhinitis, bronchitis, asthma, pneumonia,... More serious is PM fines. 2.5 affects both internal organs and increases the risk of cardiovascular diseases.Some infectious diseases can also be caused by airborne microorganisms, such as meningococcal meningitis.
PM 2.5 fine dust reaches all subjects without exception. And people who are more exposed to PM2.5 fine dust need to experience more health problems.
Especially susceptible groups of this agent include: infants and young children, the elderly, people with a history of respiratory diseases such as asthma, bronchitis, people who have a habit of smoking. , people with a history of heart disease, lung disease...
3. How to remove PM2.5 . fine dust
To remove PM 2.5 fine dust, it is necessary to understand its operating cycle. These fine dusts usually operate in a markedly increased trend at peak hours from 7 am to 8 am and from 6 pm to 7 pm, but vice versa from 13 pm to 14 pm and at night from 23 pm. From hour to 1 am, fine dust tends to decrease to low. In addition, the dust content in the air also depends quite a lot on the movement of vehicles.PM2.5 fine dust often occurs in areas with construction works or road intersections with high traffic volume. Therefore, the most effective way to clean fine dust and prevent fine dust is to limit going to these areas during peak hours. Besides, we should use masks to protect our health and avoid polluted air.
In addition, you can choose from a number of air purification devices to help reduce pollution or spread in the outdoor environment every day:
Using Ion eco-airway technology can Prevent viruses, bacteria in the air. At the same time, the filter technology also helps to keep the air fresh and fresh, helping to protect the health of the family when outside. Compact bracelet weighing from 20 grams generates 2 million negative ions that continuously bind viruses, bacteria in the air and fine dust particles into larger, heavier masses that can fall to the ground from damage. our inhalation. In addition, the device as well as the invisible mask (mask) with negative ions are able to effectively remove small pollutant components in the air, protecting the user from inhaling polluted air as well as the air. pathogenic bacteria and viruses.
