BFE (Bacterial Filtration Efficiency) refers to the barrier effect of mask materials on bacteria produced by the wearer. It is mainly used for medical surgical masks and disposable medical masks. Such products may be marked with BFE on the packaging, such as BFE99.
In the BFE test conducted by the laboratory according to the relevant product standards, it is necessary to use the bacterial culture solution to generate a large droplet spray to simulate human droplets, and spray it to the mask material at an airflow rate of 28.3 liters per minute, and then test the mask material. The interception effect usually requires at least 95% of BFE, and the effect of BFE99 will be better.
Based on the functions and applications of BFE99, we can see that this type of mask does not require a close fit with the face to achieve the purpose of protecting the surrounding environment and others. Historically, gauze masks were invented for doctors to protect patients during surgery, and have been successfully used in hospitals for hundreds of years.
Through the above introduction and analysis of the meaning of masks such as BFE99, hope it helps you.
