With the emission of car exhaust and factory waste water, it is too much for us to live in a unhealthy environment, particularly when we come across windy weather. Usually by instinct we will wear a mask to prevent dust entering our breathing system. Then a question for you: is the mask can be divided into good or bad?
Effective anti-haze masks are labeled with a clear anti-particulate respirator enforce standards, such as GB GB2626-2006, American Standard N95 or European standard EN149FFP1 etc. If you bought a mask, on the packaging or product there is not visible labels. Then at least it can be concluded that the respirator is without mandatory standard certification and there is a high possibility that it is a pseudo anti-haze masks. The second is to check if there is inspection reports. The test report issued only by the authority department can be useful. Widely recognized in the industry is the national authority detection masks labor protection products quality supervision and inspection center or a medical device detection and the like. Therefore, you have to check before buying masks to see if it indicates having passed GB2626-2006 standards. Only with the standard adopted, can it is able to show masks anti-fog and haze pm2.5 or instructions on the packaging.
Finally tips for you, PM2.5 does great harm to the human body due to minor nature of its particles and ordinary masks and cannot achieve a good defensive effect. Under severe haze weather, we recommend you try to wear KN95 anti-haze masks.
