Why is the haze frequent?

Haze weather has both meteorological reasons and pollution reasons. The main reasons for the haze weather are as follows:

1. Increasingly serious air pollution is the main cause of smog formation. A large number of polluting enterprises that do not meet the national environmental protection standards, such as the traditional steel industry, still use a large number of backward equipment. Waste gas and waste residue, including sulfur dioxide, nitrogen oxides and inhalable particulate matter, are the initiators of smog, which is extremely harmful to human health.

2. Private cars are prevalent, and traditional cars can only use gasoline fuel. A lot of automobile exhaust contains a lot of toxic particles, which is an important reason for smog.

3. Unreasonable urban planning and construction, low degree of greening. Flowers and trees are important media for absorbing, decomposing and treating air pollutants, especially carbon dioxide and dust particles. But the present situation is that our greening level is still relatively low, and we need more green messengers to protect our homes.

Hazy weather will also lead to the widespread spread of various infectious viruses with the aggravation of smog. Therefore, wear a mask when going out in foggy days to minimize outdoor activities. Try to use the air purifier at home. If you don't know the air purifier, introduce the function of the purifier.

Role 1:? Dust removal function. Removing dust, pollen and suspended particles from indoor air can effectively prevent respiratory diseases.

Role 2:? Air purification function. It can remove dust, smoke and organic volatiles such as formaldehyde and benzene in the air.

Function 3: Deodorization and deodorization function. Remove indoor residual harmful gases such as formaldehyde, toluene and ammonia, as well as life odor such as tobacco and alcohol; ? The indoor pollution removal rate reached 99.5%.

Role 4:? Sterilization function. Has the functions of sterilization and disinfection, is safe and harmless, and kills germs and viruses in the air; ? The killing rate of natural bacteria in the air reaches 99%.

Role 5:? Kill staphylococcus aureus and Escherichia coli, etc. Obviously increase the oxygen and negative oxygen ions in the indoor air, and provide fresh air.

Role 6:? In addition to small particles such as pm2.5.pm3.0, reduce indoor pollution concentration and prevent smog from posing a threat to human body.

Smog weather often happens, so we should plant more trees, drive less, live a low-carbon life, use more air purifiers at home, and don't open them casually in foggy days.
