Introduction

In recent times, personal protective equipment has become an essential part of public health strategy. Among these, 3-layer disposable masks play a critical role in reducing the spread of infectious diseases. This article examines the specific advantages of using 3-layer disposable masks, focusing on their composition and effectiveness.

Construction and Functionality of 3-Layer Disposable Masks

3-layer disposable masks are constructed with three distinct layers, each serving a unique purpose:

1. Outer Layer: Typically made from non-woven fabric, it acts as a water-repellent barrier to protect against droplets.
2. Middle Layer: This is the filter layer, often made from melt-blown material, designed to trap pathogens and small particles. It typically achieves a filtration efficiency of at least 95%.
3. Inner Layer: This absorbent layer is in contact with the face, capturing moisture and providing additional comfort for the wearer.

Benefits of 3-Layer Disposable Masks

The benefits of using 3-layer disposable masks are numerous and can be quantitatively assessed:

• High Filtration Efficiency: The middle melt-blown layer achieves a bacterial filtration efficiency (BFE) of ≥95%, effectively reducing the risk of inhaling pathogens.
• Fluid Resistance: The outer layer is fluid-resistant, an essential feature in preventing droplet penetration, which is particularly important in healthcare settings.
• Breathability: Despite their multi-layer design, these masks maintain adequate breathability, with pressure drop values typically less than 49 Pa/cm², ensuring comfort during extended wear.
• Disposable Nature: The single-use design reduces risks of contamination and eliminates the need for complex sanitization processes required for reusable masks.
