With the emergence of a large number of haze weather, PM2.5 has officially entered our lives, and the PM2.5 concentration of air monitoring has once again exploded. How to deal with such a harsh living environment? People who are aware of pollution, except to go out as little as possible In addition, I also chose to wear a mask to stop the intrusion of PM2.5.

However, when a large number of mask products on the market claiming to be dustproof and anti-haze, and have a good filtering effect on inhalable particulate matter PM2.5, are constantly out of stock, do you feel that the masks you bought bring you safety?

According to GB 18401-2010 "National Technical Standard for Basic Safety of Textile Products", a PH value between 4.0 and 8.5 is a qualified product, a neutral pH value is 7.0, and a "pro-net" product has a pH value of 7.2, which is the closest of all products. Neutral and minimally irritating to the human body. It is also suitable for people with sensitive skin.

Wearing a mask varies from person to person. People with respiratory diseases and the elderly should not wear masks with high resistance. It is best to close the doors and windows when the weather is bad and stay out at home. Children should not wear masks with large breathing resistance. The size of the mask should be suitable for the childs face shape. Once the child is not comfortable breathing, it should be replaced in time. It should be reminded that the environment inside the mask is very suitable for bacterial growth, so it is necessary to keep the mask clean and clean and disinfect it regularly.
