Introduction

N95 masks and surgical masks are widely used for respiratory protection. Although they may appear similar, they are designed for different purposes. Understanding their differences is critical for selecting the appropriate mask for specific situations.

Composition and Structure

N95 masks consist of multiple layers of non-woven polypropylene fibers. These fibers are electrostatically charged to enhance filtration efficiency, and the masks generally include an adjustable nose clip for a tighter fit. Surgical masks have a three-layer structure comprising an outer hydrophobic non-woven layer, a middle melt-blown layer for filtration, and an inner absorbent layer.

Filtration Efficiency

N95 masks are designed to filter out at least 95% of airborne particles with a diameter of 0.3 microns. Their performance is verified by the National Institute for Occupational Safety and Health (NIOSH). In contrast, surgical masks primarily protect against large droplets, sprays, and splashes; their filtration efficiency can vary significantly, typically offering lower protection against smaller particles.

Fit and Seal

One of the key differences between N95 masks and surgical masks is the fit. N95 masks are designed to form a tight seal over the face to minimize leakage. The fit is often tested through qualitative and quantitative fit tests. Surgical masks are looser-fitting and do not provide the same level of seal against the face, allowing more air leakage from the sides.

Intended Use and Regulations

N95 masks are primarily intended for medical personnel, frontline workers, and others who require high levels of protection from airborne particles. They are regulated by NIOSH under 42 CFR Part 84. Surgical masks are intended for use during surgical procedures and in environments where there is a risk of fluid exposure. They are regulated by the FDA under 21 CFR 878.4040.
