What is PM2.5 and what are the air pollutants? 
With the serious indoor and outdoor air pollution around the world, pm2.5 has repeatedly exploded, and many cities have smog weather. More and more people are beginning to pay attention to an otherwise unfamiliar term – pm2.5. So, what does pm2.5 mean?

Before we understand the hazards of pm2.5, let’s take a look at what pm2.5 means. Pm is the abbreviation of English particulate matter, translated into Chinese called particle. Pm2.5 refers to particulate matter with a diameter less than or equal to 2.5 microns in the atmosphere, sometimes referred to as lung particulate matter. Most of the common haze weather in our daily days is caused by pm2.5. Although pm2.5 is rarely contained in the atmosphere, pm2.5 is truly worthy because of its small mass, long time to carry viruses and harmful substances, diverse transmission channels, long moving distances, and great harm to human body. Invisible killer! There is data showing that because I don’t understand what pm2.5 means, the harm to pm2.5 is not enough. In 2010, the number of people killed by PM2.5 pollution in Beijing and Shanghai was 2,349 and 2,980 respectively. It is much higher than the number of local traffic accident deaths. An icon from NASA in the United States shows that the content of pm2.5 in our country has even surpassed that of the Sahara Desert, and it has become a veritable country.
What are the air pollutants:
1. Outdoor air pollutants:
Sulfur oxides, carbon oxides, nitrogen oxides, hydrocarbons, PM2.5 in the atmosphere, etc.;
2. Indoor air pollutants:
There are mainly carbon dioxide (CO2), formaldehyde, benzene, TVOC, mold, bacteria, pathogens, pet hair, kitchen fumes and so on.
Indoor pollution is 5 times that of outdoor pollution!
How to clear indoor pm2.5
In the face of outdoor smog, the interior is also inevitably affected. The smog of the national environment as the individual itself, we can not prevent, but indoors we still have a way to manage pm2.5.
Numerous experts in the field of environmental protection in the United Nations have confirmed that the eco-grade negative oxygen ion air purifier can take the initiative to capture small particles of dust, causing it to coagulate and precipitate, effectively removing dust of 2.5 micron or less and even 1 micron particles. Reduce the harm of pm2.5 and more human health. The effect of ecological-grade negative oxygen ions on air purification is caused by the combination of negative ions and particles of bacteria, dust and smoke in the air waiting for positive electricity, and they are gathered into balls to eliminate pm2.5. Hazard.

Development Trend of Water Purification Market 2019 Posted on  May 10, 2019   by  olans228 According to the offline monitoring data of AVC, the development speed of high-throughput products greater than or equal to 200L is fast and increasing. The proportion of high-throughput products is nearly 64% in the first half of the year, while the share of low-throughput products is gradually decreasing. The water purification industry is developing towards the direction of large flux, long life, high water saving, and intelligentization. More consumers have opted for high-throughput reverse OSMOSIS WATER PURIFIERS Reverse osmosis technology  has gradually become the mainstream of the market, in ultrafiltration, activated carbon, nanofiltration, and other technologies ranked first. In the first half of 18 years, reverse OSMOSIS technology products accounted for 90% of the total. Large flow for Reverse osmosis with WIFI will be very hot for the market. Welcome...

PM2.5 Air Quality Index

图片
PM2.5 Air Quality Index Here provides comparisons of air quality based on factors that have been shown to increase risk from air pollution. These factors can include life stages (children and older adults), specific health conditions (heart or lung disease), and increased likelihood of exposure from being active outdoors. The Air Quality Index (AQI) is the official index for air quality across the United States. The AQI ranges from 0 to 500. The higher the AQI value, the greater the level of air pollution and the greater the health concern. When AQI values are between 101 and 150, or code orange, members of sensitive groups may experience health effects. This is because they are more likely to be affected at lower air quality levels than everyone else. For example, children and older adults, people with lung disease, and people who are active outdoors (outdoor workers) are at greater risk from exposure to ozone. Older adults and children, and people with heart or lung disease ar...
