Introduction

N95 masks are a crucial component in personal protective equipment (PPE) used to safeguard individuals from airborne particles, including pathogens, allergens, and pollutants. The use of N95 masks became globally prominent during the COVID-19 pandemic, highlighting their importance in public health safety and medical environments.

Purpose of N95 Masks

The primary purpose of the N95 mask is to reduce the wearer's exposure to airborne particles, including small particle aerosols and large droplets. It is classified as an air-purifying respirator that filters at least 95% of airborne particles, based on standards set by the National Institute for Occupational Safety and Health (NIOSH).

Features and Specifications

N95 masks are made of multiple layers of synthetic fiber, with the outermost layer acting as a coarse filter and the inner layers providing finer filtration. Key specifications include:

• Filtration Efficiency: ≥ 95% for 0.3-micron particles.
• Breathability: Resistance should not exceed 350 Pa for inhalation and 250 Pa for exhalation under standard conditions.
• Fit: Designed to achieve a close facial fit for optimal protection.
• Fluid Resistance: Provides a degree of fluid resistance, protecting against splashes and sprays.

Performance Evaluation

N95 masks undergo rigorous testing to ensure compliance with safety standards. The following are key performance metrics:

• Filtration Efficiency: Laboratory tests confirm ≥ 95% efficacy against 0.3-micron sodium chloride particles under specific conditions.
• Fit Testing: Fit tests are conducted to ensure the mask seals effectively on the face, minimizing leakages.
• Resistance Tests: Assess the mask's ability to remain breathable while blocking particulates.
