OMEX- N95 Respirator Face Mask – Available with or without Exhalation Valve (50 Pcs)

N95 face masks are designed to filter at least 95% of airborne particles, providing effective respiratory protection. They are available in two primary configurations: with an exhalation valve and without an exhalation valve. Below is a detailed comparison of both types:

N95 Face Mask with Exhalation Valve

Description:

• Design: Incorporates a one-way exhalation valve to facilitate easier breathing.
• Purpose: Enhances user comfort by reducing heat and moisture build-up inside the mask.

Key Features:

• Breathability: The valve allows exhaled air to escape, making it more comfortable during extended use, especially in hot or humid conditions.
• Filtration Efficiency: Provides the same level of inhalation protection as non-valved N95 masks, filtering at least 95% of airborne particles.
• Source Control: Less effective in preventing the spread of respiratory droplets from the wearer, as unfiltered exhaled air is released through the valve.

• Specifications:

  • NIOSH Approval: Certified under NIOSH 42 CFR 84 N95 requirements.
  • Usage: Suitable for environments where user comfort is prioritized, and source control is not critical.

  Example Product:

  • 3M™ Particulate Respirator 8511, N95: Features the 3M™ Cool Flow™ Exhalation Valve for enhanced comfort.

  N95 Face Mask without Exhalation Valve

  Description:

  • Design: Lacks an exhalation valve, ensuring that both inhaled and exhaled air pass through the mask's filter material.
  • Purpose: Provides respiratory protection while also serving as source control to prevent the spread of respiratory droplets.

  Key Features:

  • Breathability: May feel warmer and slightly more resistant to exhalation compared to valved versions, due to the lack of an exhalation valve.
