What does 95% BFE mean?

BFE stands for Bacterial Filtration Efficiency, which is a measure of the effectiveness of a material at filtering out bacteria. The BFE value is expressed as a percentage, and a higher percentage indicates a higher level of filtration efficiency.

For example, if a material has a BFE of 95%, it means that it is able to filter out at least 95% of bacteria that are present in the air or on a surface. This makes the material effective at preventing the spread of bacteria and other microorganisms.

BFE is commonly used to evaluate the effectiveness of face masks and other personal protective equipment (PPE) at filtering out bacteria and other microorganisms. It is important to use materials with a high BFE value when selecting face masks and other PPE, in order to help prevent the spread of bacteria and other infectious agents.

What is a KN95?

KN95 is a type of face mask that is designed to filter out at least 95% of bacteria and other microorganisms. The mask is designed to fit closely over the nose and mouth, and it is typically made of multiple layers of materials, including an outer layer of non-woven fabric, a middle layer of melt-blown fabric, and an inner layer of non-woven fabric.

KN95 masks are commonly used as personal protective equipment (PPE) to help prevent the spread of infectious diseases, such as COVID-19. They are similar in design and function to N95 masks, which are used in the United States, but they are certified to meet different standards. KN95 masks are certified to meet Chinese standards for filtration efficiency and inhalation resistance, while N95 masks are certified to meet American standards.

In general, KN95 masks are effective at filtering out bacteria and other microorganisms, and can help to prevent the spread of infectious diseases. It is important to use them properly, and to follow all local guidelines and recommendations for their use.

What is NIOSH?

NIOSH is the National Institute for Occupational Safety and Health, which is a federal agency of the United States government. The mission of NIOSH is to provide research and recommendations for the prevention of workplace injuries, illnesses, and deaths.

NIOSH is part of the Centers for Disease Control and Prevention (CDC), which is a part of the U.S. Department of Health and Human Services. NIOSH conducts research, develops guidelines and recommendations, and provides education and training on a wide range of occupational health and safety topics.

Some of the key areas of focus for NIOSH include workplace safety and health, occupational injuries and illnesses, occupational noise exposure, hazardous materials and substances, and emergency response. NIOSH also plays a critical role in the development and approval of safety standards for a variety of products and equipment, including respirators and other personal protective equipment.
