- What is the difference between P2 and N95 masks?

Introduction

The P2 and N95 masks are both widely used for respiratory protection against airborne particles. However, they are often compared due to their similar appearance and purpose, yet they differ in several critical areas. This article provides a detailed comparison of these masks, focusing on their technical specifications, physical characteristics, filtration efficiency, and fit.

Technical Specifications of P2 and N95 Masks

The P2 mask is certified under the Australian and New Zealand standards (AS/NZS 1716:2012), whereas the N95 mask is certified under the US NIOSH standards (42 CFR 84). Both masks are designed to reduce the wearer's exposure to airborne particles, including aerosols.

• P2 Mask: Must filter at least 94% of airborne particles.
• N95 Mask: Must filter at least 95% of airborne particles.

Physical Characteristics

Despite their similar functional purpose, P2 and N95 masks may have different physical characteristics based on the standards they adhere to.

• Materials: Both masks typically use non-woven polypropylene fabric.
• Design: They are both available in cup and foldable designs, but differences may exist in the design specifics based on regional preferences.
• Color and Markings: Masks might differ in color coding and markings as per local regulatory requirements.

Filtration Efficiency

Filtration efficiency is a critical factor distinguishing P2 and N95 masks. The N95 mask must demonstrate at least 95% filtration efficiency for particles of 0.3 micrometers in diameter, while the P2 mask must demonstrate at least 94% filtration efficiency.

Both masks undergo rigorous testing to verify their capability to filter out particulate matter, including dust, mist, and fumes. The slight difference in filtration figures can affect the choice of mask depending on specific environmental requirements or standards.

Fit and Seal Capability

Proper fit and seal are essential for the effective performance of any mask. Both P2 and N95 masks are designed to form a secure seal around the face, minimizing leakage.

The performance of the mask heavily relies on fit testing, which ensures that the mask effectively limits the exposure of the user to airborne particles. Although the standards may differ slightly, both require rigorous checks for facial fit and seal.
