Half face masks can be divided into two types: half face masks and full face masks. Half face masks are generally used in relatively relaxed work environments with short working hours, such as installation, assembly, maintenance, etc. Full face masks are suitable for environments with complex conditions and high concentrations of harmful substances, such as chemical, refining, metallurgical, and spray painting.
According to different types, the service life of half masks also varies. The service life of a half face mask is generally around 6 months, while a full face mask can be used for more than 1 year.
