Information
How to choose PM2.5 masks? Today's cities are full of haze, and the air quality is worrying. We discuss that masks refer to protective masks specially designed for PM2.5, while ordinary civil masks are mainly used to keep out the cold. Their materials and specifications have no unified requirements, but in fact, they have no effect on PM2.5 and disease prevention.
 
The Chinese name of PM2.5 is fine particle. Fine particle refers to the particles with an equivalent aerodynamic diameter of less than or equal to 2.5 microns in the ambient air. Because the particles are too small, conventional masks such as cotton masks are difficult to work. In terms of purchasing PM2.5 masks, the higher the specification is, the better the protection level is, the greater the resistance to normal breathing, and the worse the comfort when wearing them. If you wear the products of this specification for a long time, even severe hypoxia may occur.
 
And when the shape of PM2.5 mask does not fit the face, the dangerous substances in the air will enter the respiratory tract from the place where they do not fit, even if you choose a mask with the best filter material. It can't protect your health. So now many foreign laws and standards stipulate that workers should regularly test the fit of masks, in order to ensure that workers choose the right size of masks and wear masks according to the correct steps, so masks must be divided into different sizes to deal with different groups of people.
 
In addition, active carbon masks are more popular at present. This kind of masks can effectively block the smell due to the addition of active carbon while taking into account the efficiency of dust prevention. When you choose this product, you must see clearly its efficiency of renting dust, not just confused by activated carbon.
 
It is recommended to wear PM2.5 respirator with breathing valve as much as possible, so as to reduce the stuffy heat caused by wearing respirator for a long time. At the same time, the lighter the better .
