1, what is the haze?
Haze is suspended in a large number of tiny dust particles, smoke particles in the atmosphere or sand aggregate, make the air turbidity, horizontal visibility to less than 10 km of a weather phenomenon, haze has milk-white, generally it lessened the color of the object, make the light in the distance the object microstrip yellow, red and dark microstrip blue object.
According to the city center for disease control and prevention - 2013
Related studies in 2015 found that haze main components are water soluble inorganic ions (
Nitrate, ammonium sulfate and ion, etc. )
, metals and metals (
Lead, cadmium, arsenic, etc. )
, carbon material (
Organic carbon and inorganic carbon)
And so on.
2, haze, influential to the body?
Smog has an impact on the human body!
According to data of fog on the health effects of the generally divided into direct effect and indirect effect.
Direct impact: the main atmospheric pollutants concentration is increased sharply in a short time, people can be caused by a large number of pollutants inhaled acute damage, respiratory and eye irritation, symptoms such as cough, sore throat, headache;
If long-term exposure can cause chronic inflammation, decreased immunity, allergies, etc.
Indirect effects: through the indirect effect of long term, such as by influencing the radiation from the sun and tiny climate, produce the greenhouse effect, ozone depletion, acid rain, affect our health.
3, why haze weather out less activity?
The city center for disease control and prevention - 2013
2015 studies show that under the condition of the doors and Windows sealed, serious indoor PM2 haze weather.
5 concentration is lower than outdoor concentrations of three to forty percent, it is recommended that the fog haze weather to minimize outdoor activities, especially to reduce the time and strength of the outdoor sports.
4, smog coming do you want to wear a mask?
How to choose?
How to wear a mask?
Haze days if you must go out wearing a face mask is the main protective measures.

A level corresponding & other;
Serious pollution & throughout;
In the PM2.
5 concentration using up to 500 ug/m3;
D corresponding & other;
Moderate and throughout the following pollution &;
5 concentration is less than or equal to 150 ug/m3.
Use it shall comply with the instructions to wear mask.
Wear must be completely covered the nose and mouth and chin, mask and facial fit closely, sealing the better protective effect is better.
5, what issues should be paid attention to when wearing masks?
Not everyone is suitable for wearing a mask.
Masks the seal structure and the filtering material increases respiratory resistance, reduce the comfort.
Different people wear masks to note: pregnant women wearing the respirator, combined with their own conditions, should be paid attention to choose comfort better products, such as an exhalation valve respirators, reduced expiratory resistance and hot feeling;
Children are in growth stage, and its face is small, general mask is difficult to achieve or effect, advised to choose a normal manufacturer production children respirators;
Elderly people, chronic patients and patients with respiratory system diseases, such as special advice when people wear masks should be used under the guidance of professional doctor.
Masks are not suitable for long time wearing, on the one hand, masks external adsorption the particulate pollutants, causing respiratory resistance increased;
On the other hand mask internal also accumulates breath of bacteria, viruses, etc.

have certain effect to purify air.
When choosing to pay attention to the following three points: first, clear purpose, to choose and buy of PM2.
5 has the purification effect of purifier;
The attention to the performance index, the air sterilizer
according to the national standard, a truly effective air purifier
to do air disinfection machine & other;
3 tall one low & throughout;
Noble and pure clearance volume: clean air quantity (
Is air disinfection purification effect index, CADR value, the greater the purification ability of sterilizer stronger, purification effect is better.
High cumulative purification rate: the cumulative amount of purification,
The more the higher the value, purification of the contaminants, filter the longer service life.
Efficient value: the higher the level of energy efficiency, save electricity.
