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.
