Of course I dare to use the Steadfast mask. Steadfast is registered with the State Drug Administration, you can check their medical device product registration certificate.
Every employee in the Steadfast factory follows a strict process of temperature testing, disinfection, donning and hand hygiene. Employee hands are tested weekly for microbial content. And the masks are produced in a 300,000 class clean room, where the floor is disinfected and sterilized with ultraviolet disinfection lamps every day, and then tested for planktonic and sedimentary bacteria.
The finished products are sterilized by ethylene oxide after production, and the fully enclosed carton packages are sterilized by the advanced electron beam sterilization method, which is strictly controlled throughout the whole process. The disposable mask is a medical mask, which can well block the spread of blood, body fluids and splashes. This mask is in full compliance with the national standard for medical surgical masks, with N95 filtration layer, the filtration rate reaches 95%, and it also has a 3-layer pleated design, which can be adjusted according to the face size, and it is very comfortable to wear.
