Lab Face Mask

Description

N95 masks are a type of respiratory protective device designed to achieve a very close facial fit and efficient filtration of airborne particles. They are commonly used in healthcare settings and industrial workplaces to protect the wearer from airborne particles and liquid contaminants.

N95 masks are made from electrostatically charged polypropylene fibers that are designed to capture particles in the air. They can filter out at least 95% of airborne particles, including large respiratory droplets and smaller aerosols.

N95 masks are regulated by the National Institute for Occupational Safety and Health (NIOSH) and are classified as a type of personal protective equipment (PPE). They are different from surgical masks, which are designed to protect the patient from the healthcare professional’s respiratory secretions rather than the other way around.

The fit of an N95 mask is critical for proper protection. It should be snugly fit around the nose and mouth with no gaps or leaks. A fit test can be performed to ensure proper fit, and healthcare professionals who use N95 masks should undergo fit testing annually.

During the COVID-19 pandemic, there has been a global shortage of N95 masks, leading to a search for alternative types of respiratory protection. Some healthcare professionals have used reprocessed or expired N95 masks, but these practices are not recommended due to potential risks to the wearer.
