N95 respirators are a type of personal protective equipment designed to achieve a close facial fit and efficient filtration of airborne particles. They are primarily used in healthcare settings to protect against respiratory hazards, including viruses and bacteria. The "N95" designation indicates that the respirator can filter at least 95% of airborne particles, making it a crucial component in infection control protocols.
    
These respirators are equipped with a filter that is capable of trapping microscopic particles, including those that are too small to see. Proper fit is essential for maximum efficacy, as any gaps can allow unfiltered air to enter. N95s are often used during outbreaks of respiratory diseases, including influenza and COVID-19, to safeguard both healthcare workers and patients.
    
In addition to their use in healthcare, N95 respirators can be employed in various industrial settings where workers are exposed to hazardous airborne substances. It is important for users to be trained in the proper use and maintenance of these respirators to ensure optimal protection.
